Sometimes there are situations when, when shooting from a copter, the horizon “collapses”. The effect is not fatal, but unpleasant, spoiling the picture and attitude to shooting. The DJI X5 and X7 cameras allow this effect to be deliberately achieved with dynamic shooting, but in this case it is a justified step.
In some cases, problems arise due to errors in setting the gimbal for new drones, and in some situations, there are no visible reasons for the appearance of such a problem. Calibration allows you to eliminate a defect in the picture, which almost every person can do on their own at home.
DJI Gimbal Calibration
In general, the calibration procedure is identical for most DJI quadcopters, including the Mavic series and the Phantom family.
Simple calibration requires you to turn on the aircraft and remote controller, connect to the remote controller via your smartphone, and turn on the DJI Go 4 app.
After entering the camera window, you must click on the image of the ellipsis (upper right corner)
In the drop-down menu, select the option “suspension”
In this submenu, the line “Calibrate Gimbal” is selected
Calibration requires the copter to be on a level, stable surface that does not wobble.
After the calibration is done, you need to reboot the quadrocopter.
In the absence of a positive result, the problem may lie in the accelerator that was damaged earlier. It, in turn, can affect the IMU. Its calibration is recommended even if the system does not warn about the presence of problems in this element.
Calibrating Inertial Measurement Sensors (IMUs)
Calibration is carried out on a flat surface. The process begins similarly to the previous option, by selecting the three dots in the corner of the screen.
The topmost sub-item in the form of a copter is selected
In the proposed list, the action “Advanced Settings” is selected
Next, select the sub-item of the new menu “Sensors State”
Under the values of each of the sensors there is a button “IMU Calibration”
Next, the user is required to execute commands prompts displayed by the system on the camera screen.
Upon completion of the calibration, the drone will reboot.
Calibration did not change the situation
Horizon obstruction can occur when the copter is turning in flight. Sometimes, the camera is initially installed with an inclination to one side, and even with a straight movement it gives a blockage.
In such a situation, problems may lie in the correct operation of the compass, which is responsible for the accuracy of determining the direction. It can fail for various reasons, for example, due to metal being located close to each other, proximity to a car subwoofer, or other circumstances.
The compass can also be self-calibrated. This will require a wasteland devoid of metal objects. Metal, if possible, should not be on a person (rings, chains, watches). It is required to turn on the drone, connect to the control via a smartphone, select the ellipsis in the corner of the screen.
In the menu that appears, click on the quadrocopter (first in the list)
Select “Advanced settings” from the list
In the next submenu, select the option “Sensors state”
Then click “Compass” — “Calibrate Compass”.
After that, you only need to follow the prompts displayed on the screen. If successful, it will start flashing green. A red flash will indicate a failed attempt. It can be repeated in an identical way, but moving even further away from any metal objects, so as not to knock down the fine settings.
If this does not help, you will need to reset the compass. This procedure requires the use of special equipment, so for its implementation you will need to contact our service center. This procedure is carried out free of charge, and the owner of the copter is only required to go through a preliminary appointment using a phone or e‑mail.
Other causes of gimbal instability
The so-called “horizon collapse” in dynamic turns is also widespread. It is almost impossible to completely get rid of such a problem, and calibration will only reduce the size of the effect, making it less visible. In this case, there are two situations: a flat horizon in place with a littered one. In the latter case, mechanical damage may be the cause of the problems, so the drone should be shown to service specialists who will check it and, if necessary, carry out the necessary repairs.
