Embodiment Construction

[0017] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0018] Method example:

[0019] figure 1 The flow chart of the embodiment of the UAV IMU collision detection method provided by the present invention, the specific implementation steps of the anti-collision method are: when the UAV collides with an object, the following steps are performed, S101 detects the signal input by the IMU sensor in the UAV ;

[0020] Specifically, when a collision occurs, the IMU sensor will generate a collision signal, but the collision signal will be mixed with the vibration signal of the normal flight of the UAV. At this time, it is necessary to filter out the normal flight signal, and then pass the filtered signal to the into the drone;

[0021] S102 Determine the direction of the collision through the IMU input signal.

[0022] Specifically, the UAV does a large number of collision experiments in advance, and the IMU data ge...
