Embodiment Construction
[0039] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0040] figure 1 It is a flow chart of the obstacle avoidance path planning method based on the shortest distance vector field histogram provided by the present invention. like figure 1 As shown, the obstacle avoidance path planning method based on the shortest distance vector field histogram provided by the preferred embodiment of the present invention includes steps S1-S3.
[0041] Step S1: Divide the current scanning range of the robot into n sectors, if the shortest distance vector between the obstacle in the kth sector and the center point of the robot is NDV k , Get|NDV k-1 -NDV k |Compared with the diameter of the robot, the number of obstacles in the local environment of the robot's curre...
