Now, taking DJI Elf series UAV as an example, the basic operation method of UAV is introduced, and the operation of other brands of UAV may be different. Open it&; Power off: Press the power button on the battery/remote controller once, and then press the power button for 2 seconds after the indicator light comes on. When all the indicator lights are fully charged, let go, and the power of the drone and the remote controller can be turned on smoothly.
Check that no one will complete the basic hardware self-test after booting. The states of IMU (Inertial Measurement Unit), compass, pan/tilt and motor can be viewed in the supported mobile phone client DJIGo and calibrated according to the corresponding methods. At this time, users need to manually check: the remaining power, voltage and battery life of the aircraft.
Remote control signal, picture transmission signal, you can also check the interference level of the current picture transmission signal channel in the setting menu. If the interference is serious, you need to manually adjust the channel. Compass status. In theory, the compass does not need to be calibrated frequently, but for safety, please calibrate the compass manually before each takeoff, and stay away from all metal objects when calibrating.
SD card remaining capacity. The power of drones is limited. It would be a pity if you waste electricity and can't take pictures.
Take-off: After all the inspections are completed, everyone can start the motor. The motor starting mode of DJI and Zero-degree UAV is to toggle the two rockers below the center line of the remote controller in the form of "inner eight characters". After starting the motor, the motor will drive the propeller to idle. By default, the rocker on the left side of the UAV remote controller is responsible for controlling the UAV to rise, fall, rotate to the left and rotate to the right.
The rocker on the right is responsible for the horizontal movement of the drone. When taking off, just push the left rocker up slowly, and slightly increase the throttle when the drone leaves the ground, so that the drone can rise to more than 2 meters as soon as possible, and then it can fly freely.
Wizard 4 remote control has built-in photo and video buttons, which can be clicked to start recording or taking photos. After recording, you can click the "Play" button to view the captured videos and photos on the mobile phone client. With DJIGo, you can choose between automatic exposure and manual exposure. Using the setting wheel in the upper right corner of the remote control, you can adjust the exposure compensation or shutter speed directly on the remote control.
A must-have aerial camera for novice drones
Straight flight: Straight flight means that the drone flies straight in only one direction, such as up and down, back and forth, left and right, or along the diagonal. Flying in a straight line is very simple, just dial the joystick in a specific direction. When flying, with the stable rotation of the pan/tilt, the picture can be focused on an object. When the lens shoots a rising or falling picture vertically to the ground, if the plane rotates slowly, it can also improve the impression of the picture.
Orbital flight: Orbital flight, referred to as "brush pot", refers to the uniform flight of an aircraft around a shooting target. During the flight, the shooting target is always in the center of the picture, which is suitable for showing the surrounding environment where the object is located and has a strong three-dimensional effect. Orbital flight can be divided into rotation and lateral flight of aircraft. You can "brush the pot" by pulling the two rockers of the remote control in opposite directions at a specific rate.
Tracking flight: a "variant" of flying in a straight line or flying around, which takes a moving target as the tracking object and enhances the movement of the picture. Dive/Pull-ups If you think that flying in a straight line is too simple and hovering tracking is too complicated, you can try this compound lens shooting. When flying horizontally, you can toggle the left rocker to make the plane rise or fall at the same time. The shooting of this kind of lens requires the operator to have a good sense of three-dimensional space.
