Each UAV launched by Dajiang Innovation in recent years is not the focus and hot topic of the digital industry and intelligent hardware industry. Every digital enthusiast yearns to have his own fairy, or even a more high-end Wu series. I started to play with the assembled multi axis aircraft a few years ago, and got a basic understanding of unmanned aerial vehicles. It is also from that time that I learned about innovation in Xinjiang. Every time I saw a reality show on TV with a cloud of somersault hanging on a SLR shuttling back and forth in the sky, I was very curious and yearning, so I started my own way to assemble drones and played for two years. At that time, I felt very good about myself. I felt that the UAV assembled by myself could fly very well. It was also possible to take aerial photos with a sports camera. Until one contact GJI I was deeply poisoned after watching its steady attitude of taking off, hovering in the air like a sea calming needle, and the pictures taken were clear and stable. It feels like the previously assembled UAVs are all toys. And this time I'm lucky to experience the latest version of DJI Phantom4 It is very lucky. Talk less and start this experience right away.

DJI Phantom4 is the latest generation of Genie UAV launched by Dajiang Innovation at the beginning of the year, and this UAV has put Dajiang Innovation in the front row of the industry. DJI Phantom4 uses various advanced intelligent technologies to give users a better experience. It is also this UAV, which makes the UAV enter the intelligent era. The visual positioning system used for the first time should improve the obstacle avoidance ability of DJI Phantom 4. Whether the obstacle avoidance function is strong or not, we will talk about it in detail in the experience. The addition of this visual sensor has also enabled the DJI Phantom 4 to have more intelligent flight modes, greatly improving its playability, and its operation is simpler and more convenient than the previous wizard. The standard 4K camera captures very clear images, and the PTZ is also easy to operate through the scroll wheel and the custom key on the remote control.

    Use this experience Phantom4 I have flown many times and many places in my own city. I grew up in this city little by little and never felt the history, culture and beauty of this city carefully. This experience let me know that the city I grew up with was so beautiful. When the aircraft flew high, I also felt that I was so small, just a part of the small and medium-sized of this huge city. So I have the idea that the world is so big that I want to see it. Life time is so limited. It's a waste of time not to seize the time to see more scenery and feel more things. I forget the scenery around me when I am busy working every day. In the future, I should pay more attention to the beauty around me, go out more, see more scenery, and recover more time. Say and start to understand life, close! The book belongs to the true biography.

First DJI Phantom4 The packaging of DJI The appearance design of the spirit series is simple and clean. All are white boxes, and this time DJI Phantom4 There is no color bar attached to the fuselage of. Instead, the color light under the motor is used to distinguish the direction of the fuselage. The spirit without the color bar on the body looks cleaner and feels better overall.

In addition to the outer packing carton, the handle on the outside of the carton was integrated with the inner carton, and a foam protection box was hidden under the carton. This protection box can be said to be very conscientious. The previous version of the genie needs to purchase an additional equipment box. This time, it is a direct gift, which is more convenient to store. The gray and some metallic colors also look very textured. The soft materials under my hand make the box feel good. The design pays attention to details.

To open the storage protection box, just pull the buckle on the top of the box and rotate it clockwise ninety The upper cover can be opened by lifting it upwards. The buckle is made of metal. It can be pulled and rotated smoothly. The metal material feels good.

Open the protection box, and the lower part of the box is the mold made of the whole material, Phantom4 It is placed in the center of the box, and the preset groove firmly fixes it in its position. Because the box is made of foam material, it has certain elasticity, Phantom4 It is fixed without any gap, so it looks very safe to put it in the box. Each component has its own fixed position, and the design is compact and reasonable.

Take out all parts in the box, which are Phantom4 Body, remote control eight Paddle blades, charging power supply, data cable, data cable adapter and multi language user manual placed in the storage bag.

DJI Phantom4 And previous generations Phantom The design of the series fuselage has not changed. The integrated streamlined shell makes the visual effect look very comfortable. It is believed that the smooth streamline design will also reduce a lot of wind resistance in high altitude. And this time Phantom4 The installation mode of quick dismantling blades is used, which is much easier to operate and has a much higher safety factor than the installation mode of the previous generation of rotating blades. It should reduce a lot of propeller shooting accidents. The front and back of the blades are distinguished by the black spots at the connection of the upper blades of the motor. The specific differentiation method is described in detail below. The length and width of the fuselage are 289.5mm . Distance between diagonal motor center points is 350.00mm 。

From the side, we can see the deconstruction details of the quick release blade snap. The bottom of the snap is the spring that supports the blade upwards. The elasticity is an important factor in the number of propeller shooting accidents. The motor is gray, and the bottom is the heat sink.

Be sure to remove the protective cover on the PTZ before starting the power supply of the fuselage, or the PTZ will jam the PTZ and burn the PTZ steering motor during the PTZ self inspection after starting. Be careful, or you will regret burning the motor. The PTZ protective cover is directly stuck on the left and right landing gears, and the clips stuck on the left and right landing gears need to be removed. Remove the left clip downwards first.

Then remove the right clip. The action should be gentle, and the force should not be too strong. If the force is too strong, the PTZ will be damaged. The PTZ is very precise, and excessive action will affect the accuracy of PTZ action.

Remove the buckles on the left and right landing gears, and the protective cover of the PTZ can be removed. The PTZ is free to move when it is not powered on, and it looks fragile, so you should act gently and carefully.

We can see clearly after removing the PTZ protective cover Phantom4 The overall structure of PTZ has been improved. this Phantom4 The shock absorber of the PTZ is hidden in the battery compartment, so that Phantom4 It seems that the PTZ is much simplified and equipped with aperture F/2.8 field ninety-four ° FOV Of 4K camera.

There are many video formats available for shooting and taking pictures. Different video formats and frame rates can be selected according to different needs.

When the power is turned on, the PTZ actively maintains the angle after the command of the remote control. Regardless of the posture of the body, the PTZ always maintains the angle of the last command, and the PTZ operates flexibly and stably.

The power switch of the fuselage is on the back of the fuselage. Press it once, release it, and press it twice. The power is turned on, and the power indicator lights up. The light is green. The indicator lights under the four motors light up. After hearing a clear prompt tone, the PTZ self checks, and the PTZ camera enters the working state.

After the power supply is turned on, the motor lowering indicator lights up, the head direction lights are always red, the tail lights flash green under the normal takeoff status, the status is abnormal, yellow, and the power is low, red.

The memory card slot is on the left side of the body. Press it to eject, and the data interface is also on the side of the card slot.

The tail of the fuselage is a horizontal sonar probe and a visual probe. The probe is surrounded by dense battery compartment cooling holes. It seems that when flying, the heating capacity of the battery should not be underestimated. This is also the part that lets Phantom4 Good control of flight altitude. The appearance doesn't look like some kind of insect, which is bionic.

Phantom4 With eight Only blades, four Only forward rotating blades four Only reverse the blades. The forward rotating blade has a black cap ring on its cap, and the reverse rotating blade has a gray cap ring.

The blade length is 240mm . The blades are flexible and very thin.

When installing blades, the black spot on the slot above the motor can distinguish between forward rotation and reverse rotation. The motor with black spots is a forward rotating motor, and forward rotating blades with black cap rings are installed.

The motor without black spots is a reversing motor, which is equipped with reversing blades with gray cap rings.

When installing the blade, press the motor body and press the blade downward. The forward motor rotates counterclockwise, and the reverse motor rotates clockwise. The rotation range is not large. It feels that the blade can be installed with a click. Shake the blade back and forth to ensure that the circlip completely locks the blade, so as to avoid propeller shooting accidents during flight.

With blades installed Phantom4 Waiting quietly for takeoff. Take advantage of a ray of sunshine outside the window in the morning Phantom4 Go out for a walk and see how beautiful the world is. After getting familiar with all parts of the fuselage, let's take a look at the remote control. Before flying, be sure to understand the functions of each switch and rocker on the remote control, so that you can operate skillfully and quickly during the flight Phantom4 Flexible flight.

Phantom4 The remote control is clean and simple, and the center of the remote control head is silver DJI brand LOGO , looks very textured, the shell is white, the rocker base is black, and the black and white visual effect is very comfortable. The pan tilt control rollers on the upper left and right of the remote control are made of metal and have certain damping. All function keys, including rocker and bracket, are made of metal. The texture is very good, and the use experience is very good.

The remote control of the Genie's standard configuration PTZ series is equipped with a flat bracket. The bracket can be folded up when the remote control is not in use to save space and facilitate storage. The left and right sides of the remote control are designed with soft anti slip pads for a better feel. It feels very soft and has a very good anti slip effect. The anti-skid function plays a major role after operating the aircraft palm for a long time and sweating.

The back of the remote control also uses a large area of anti slip sticker. The material is the same as the edge material. It is very soft and has an unusual feel. The bottom is additionally designed two A custom key can be set into various shortcut functions. I set the left button to PTZ back to the center according to my own operation habit / Down, right click to set the PTZ to follow /FPV . Others can also be set into different user-defined key functions according to different operation habits, including: advanced camera settings, back to center / Down, pan tilt follow /FPV , Map /FPV Switching, battery page and undefined can meet the call of shortcut function in daily operation.

The left front of the remote control is the flight mode switch, and the modes are three Species, respectively P 、 S 、 A File. The red dot button is a video button, and the scroll wheel at the bottom is the tilt angle operation scroll wheel of the PTZ. The scroll wheel is elastic when rolling left and right, and automatically returns to the center. The surface is sawtooth treated, and the skid resistance improves the feel. Tear off the sticker on the flight mode gear switch to see the switch, which is still made of metal.

On the phone APP Of DJI GO Various flight modes are introduced in, P The mode is the most commonly used mode, and the obstacle avoidance function and GPS Functions and down looking perception positioning are all involved in the work, which is generally required for outdoor ordinary photography. S The mode is motion mode, which improves the maneuverability. The remote control operation of the aircraft can respond quickly and quickly 20m/s . The front view obstacle avoidance function is turned off, and the bottom view and GPS The positioning works normally. This is Phantom4 The new gears replace the original ones FPV In fact, the sports mode is upgraded FPV pattern. The speed is faster and the required site conditions are greater. For old players, open S The video recorded must be very shocking. A Mode is generally used indoors None GPS When it is used in mode, all safety functions are closed, and it is only operated manually. It is also the mode that most tests the operator's experience and ability. Generally, novices are advised not to use it.

On the right front of the remote control are the photographing button, the pause button, and the camera exposure compensation adjustment wheel. The exposure compensation roller is different from the tilt angle roller of the PTZ in feel. It is neither elastic roller nor automatic centering. Like the aperture roller on the camera, it is an evenly distributed click gear. this Phantom4 The pause button added to the remote control is a specially designed button for the new intelligent game guidance flight. When entering the intelligent guidance flight mode, the aircraft will fly in the set direction all the time. The aircraft will stop until it reaches the preset maximum distance or press the pause button halfway, and the aircraft will hover in place.

The fuselage battery continues the battery compartment design of previous generations of models. Just press the card up and down to pull out the battery. The weight of the battery is not small, and the weight of the whole body is reduced by half when the battery is removed.

The power switch of the machine body is designed on the smart battery. After inserting the battery, press the switch to release it once and then press it again two The smart battery is turned on. At the same time, the power display is beside the switch, four The grid light is green.

The connection interface between the battery and the body is of multi contact type, which is much more than that of the previous model. Does this increase the interactivity between the body and the battery, and make the information exchange more real-time and intelligent.

Phantom4 The battery pack of is shorter and thicker than the front battery pack, and the working voltage is also 15.2V , for 4S Lithium ion battery pack, power 5350mAh ， 81.3Wh , compared to Phantom3 It's too much 870mAh , which can make Phantom4 Staying in the air for a few more minutes is also a big improvement in endurance. Although a few minutes is not very long in ordinary times, it is really important for the aircraft to increase the dead time.

The remote control and smart battery use the same charging adapter, and the cables with different interfaces are split in the middle two Connectors, corresponding to remote control and smart battery respectively. It is convenient to use an adapter for charging at the same time. After the power is connected, the power indicator of the remote control and the smart battery will flash step by step, and the power will be fully charged and off.

Phantom4 The connection between the remote control and the display device returns to the data cable connection mode, so that it does not occupy the WIFI and 4G It is not necessary to cache the map data offline in advance, but use the real-time map data in the mobile phone or tablet in real time to avoid the situation of no map before. Although this use may sometimes lose some data traffic, it makes the aircraft increase the guarantee of real-time map data in flight, which is more stable and safe.

First, you need to download a DJI GO Go to your phone or tablet and update to the latest version. Connect the mobile phone to the remote control, Phantom4 Only the connection cable of the Android device is attached, not IOS Equipment connection line. Connect the mobile phone with the remote control, turn on the body power and remote control power, and enter APP Prompts you to connect the camera. Before connecting the camera, it was found that the firmware of the remote control and the aircraft needed to be updated. The firmware package was downloaded for upgrading. Firmware update requires connecting the phone to the corresponding device with a data cable to update the firmware. Check the updated content to improve the obstacle avoidance function. New intelligent systems always need continuous improvement to become more intelligent and easy to use.

First entry APP There will be various introductory tips to find a suitable takeoff site, which is also a necessary condition before flight. Check GPS The number of stars, check the power, and set the return altitude. The return altitude should be based on the highest object around the flight site as a reference, and should be higher than the highest object around to ensure the return safety.

First use Phantom4 The hardware needs to be activated, and the hardware warranty time is calculated at the hardware activation time node. Officially one Years of warranty. To activate hardware, you need to apply for one DJI The hardware is bound to the account after activation.

After the account is activated, you need to set the operation habit of the remote control. There are three modes: American, Chinese and Japanese. The American manual operation mode is selected by the author. The left joystick controls the height of the aircraft up and down, the left and right controls the steering, and the right joystick controls the front and rear, left and right in the horizontal direction. Next, set the parameter unit and video format. For the sake of safety, the author first chose the novice mode for operation, and then after being familiar with various operations of the aircraft, he can APP Turn off novice mode in. The novice mode is regulated in the absence of GPS Under such circumstances, takeoff is not allowed, and the flight altitude and distance are limited to a safe range.

After all the preparations before takeoff are completed, you can connect the camera to the operating system. get into DJI GO There are a lot of operation keys around the main operation page of. Novices will be dazzled when they first enter the page, but don't worry. Take your time. Each operation key is in graphic form, which is very intuitive. You can probably see the function of pressing the key from the perspective of graphics. Various parameters during flight can also be displayed on the page in real time through the image transmission system. You can also use the buttons on the remote control to quickly operate the video and camera functions.

All the preparations have been done, and I have a certain understanding of the various operations of the aircraft. Taking advantage of a sunny and spring day Phantom4 Come outside and fly in the sky. First, I chose the stadium of the nearby University of Architecture, because the venue is very open, and there are no surrounding tall buildings. Not familiar with Phantom4 Before his flying habits, it was appropriate to have an open and secure place. There is no wind around, and the temperature is also very pleasant. This weather is perfect for flying.

After the remote control is connected, everything is ready. First, the aircraft needs to search for stars, calibrate the compass for the first flight, and rotate the aircraft three hundred and sixty ° Then rotate the aircraft vertically three hundred and sixty °, after which the calibration is completed, GPS Number of connections ten After setting the takeoff location, the screen displays that takeoff is allowed. Select automatic takeoff, and the aircraft will take off automatically to leave the ground one point five Hover at an altitude of m, waiting for instructions.

Phantom4 Hovering in calm weather is very stable, like a sea calming needle. Occasionally, there is wind passing by, and the aircraft will have a small deviation, but the built-in GPS Give Way Phantom4 Return to the original position immediately.

Push the throttle rocker, Phantom4 Slowly rise to the required height and release the rocker, Phantom4 Hover at the final height and control the height through the sonar and vision system at the bottom. The lower vision probe is composed of one , upgraded to two The altitude control will be more stable.

After lifting, you can see that the indicator light below the motor lights up, two Red is always bright, two Green flashes, and red is the head direction. The indicator light can be turned off when there is sufficient sunlight to save some power. The indicator light will display at night. The brightness is still OK one hundred The sky above meters can still clearly distinguish the light indication.

Phantom4 The forward-looking system added for the first time not only upgrades the obstacle avoidance function, but also adds a lot of intelligent flight modes to the aircraft, greatly increasing the playability and controllability of the aircraft. Click the intelligent flight mode button, and the lower part of the screen will appear four There are commonly used shortcut buttons, which are pointing flight, intelligent follow, normal mode, and other intelligent flight modes.

The first is the intelligent follow mode. Click to enter, it is the flying distance of the aircraft followed by the object five Within meters, then draw a box with your finger in the camera's field of vision at will to circle the following object, and the aircraft will directly enter the intelligent following mode. During the following process, you can adjust the following height of the aircraft at will. It is not allowed to enter the intelligent follow mode when the altitude is too low. The intelligent follow mode should be like a fish in water when shooting moving objects, moving people, extreme sports and other scenes. This intelligent follow mode greatly frees the operator's hands from grasping the remote control. As long as you pay attention to the height of the aircraft at any time, it is good to avoid accidents when the flight height is too low.

The addition of pointing flight mode facilitates continuous shooting in a wide area. After selecting the pointing point and flight angle, the aircraft will fly at a constant speed in accordance with the preset direction, angle and speed until the maximum distance is reached, or the operator presses the pause button of the remote control, the aircraft will hover in place. After entering the pointing flight mode, a horizontal line appears in the center of the screen to control the flight angle.

The function of surrounding interest points is not a new function, and the operation has not changed from the previous model operation. First, fly the aircraft above the point of interest, select to set the point of interest, and then fly away from the point of interest. The fly away distance is the radius of the circle. After setting, click to start hovering around the point of interest.

Several intelligent flight modes with high playability are introduced, and other intelligent flight modes such as hot spot following, waypoint flight, homing lock, and heading lock will not be described in detail. Phantom4 Various intelligent modes play different roles in different scenes and are easy to operate.

Finally, several photos taken during the video recording are attached to show the beautiful scenery of the city from different angles. Phantom4 This one 4K The video image captured by the camera is very satisfactory, and it is fully competent for both large frame rate video required in motion mode and high-definition video required in landscape.

Write at the end

After a long period of ten Multi day and Phantom4 With Phantom4 I walked around the city where I have lived for a long time, appreciated the familiar city from another angle I have never seen before, and found the beauty of the other side of the city where I live. It is not too late to discover the beauty of this other side, which is also an opportunity for me to really go into aerial photography. I also found that I am familiar with Phantom4 Some advantages and disadvantages of. Phantom4 There is no doubt that the advanced intelligent flight system is once again ahead of other competitors in the industry. In particular, the addition of visual perception system makes Phantom4 It has really become a UAV close to intelligent robot, which can also be said to be Phantom4 It is an intelligent robot with wings. The visual perception system makes UAVs seem to have an idea, which can imitate the perception of obstacles in front as human glasses see obstacles, so as to make flight safer. It's also the visual system Phantom4 The intelligent flight mode that other UAVs do not have is added, which greatly improves the playability and operation convenience of UAVs. However, the visual obstacle avoidance function can not completely identify all obstacles. Large monochrome objects can not be identified, too smooth surfaces can not be identified, and the obstacle avoidance function will give an error prompt when the flight environment is too dark at night. Later, it should be optimized and improved through firmware update. Another powerful function of the vision system is the intelligent follow mode. This mode reduces the degree of dependence of traditional UAVs on remote control control and frees the operator's hands. When carrying out various activities, the UAV can follow itself like its own shadow, thus recording various wonderful moments. This new intelligent function is believed to be favored by more extreme sports players. Phantom4 It can be said that all kinds of probes and sensors are armed to the teeth. So many sensing devices make it stable and accurate in attitude control during flight, even when 20m/ Seconds of high-speed movement mode, Phantom4 It can also brake easily in the air. The brake response is very sensitive, and the attitude control is also satisfactory. However, battery life and cost are still problems that can not be solved by UAVs today Phantom4 It can only fly for more than 20 minutes, but only one battery is on hand. There is no replacement battery. If you want to fly more quickly, you need another battery. If you buy another battery, you need another budget. Although it is not particularly expensive Phantom4 In terms of positioning, it is also a good choice to add a battery to create a cool flying version. On the other hand, the storage of the UAV's PTZ is a problem. At the end of each flight, the PTZ needs to be stuck with the PTZ protective cover to store the PTZ in the box more safely. The protective cover of this PTZ can be improved to make it easier to disassemble, Phantom4 The protective cover is just a plastic bayonet. There is a certain risk of breakage after long-term use. Will there be a more professional PTZ protective cover for players to choose? ten Multi day and Phantom4 After getting along with each other, every flight attracted many people to look around, which satisfied my vanity. I took this snow-white industrial design with a strong sense of remote control Phantom4 Be the focus wherever you go. Of course, flying UAVs is not just for the sake of wind, Phantom4 I also saw more beautiful cities. It was really beautiful to see the world from another angle, which also made me feel the urge to go out for a walk. The world is so big, I will take it with me Phantom4 Go to see.
