If the shooting scene is converted from land to water, what should the aerial flying operator do with the aerial uav shooting the scene similar to the picture below?
Aerial uavs are usually required to take off on the surface of the boat to keep the aerial uavs in sight when following the subject of the movement on the surface of water. Unlike land filming, the risk of water environment is much bigger. What are the points for attention from aerial uav’s power, take-off and return?
Aerial uav should be powered up when the ship is as stable as possible.
Because the aerial uav has a self checking process after power up, the self inspection process will cooperate with multiple sensor modules, such as IMU, GPS module and barometer. The aerial uav needs a stable environment to complete self-test so as to ensure that the above sensors could work normally, and to make correct posture correction after take-off.
The undulating water surface will affect the calibration process of the initialization of the sensor, which leads to the failure of the calibration. If the self inspection cannot be passed, the subsequent flight program can not be carried out.
The attitude mode should be used for the takeoff of a aerial uav on a ship
Because most of the ship's body is made of steel, it may interfere with the surrounding magnetic field. Under the GPS positioning mode, the compass interferes with the magnetic field, causing the direction sensing error and the UAV moving to a certain direction, which will lead to the danger of collision. Therefore, calibration of compass should be carried out at shore before calibration.
The aerial UAV's runaway behavior is set to "runaway hovering"
Because the aerial UAV
will record the current GPS coordinates as the return point when taking off and the ship only moves away from the take-off point in the shooting process, it will not fall back to the ship but fall back to the take-off point when the UAV is out of control. That is, the starting point has already been the surface of water.
Protect equipments from being dampened
The moisture on the water is even bigger. When the aerial UAV is not flying, the staff should take the equipment in the box or the package in time to prevent the moisture of the precision parts.
