Unmanned vehicle path planning method, system and terminal

The invention discloses an unmanned vehicle path planning method, system and terminal, and the method comprises the steps: obtaining an image shot by an unmanned aerial vehicle, and carrying out the semantic segmentation of the image, so as to recognize a ground unmanned vehicle and an obstacle; extracting an interested area in the image, and positioning a ground unmanned vehicle and an obstacle based on the position of the unmanned aerial vehicle; and planning the shape of the ground obstacle according to the positioning result of the ground unmanned vehicle and the obstacle, and performing path planning on the ground unmanned vehicle according to the shape planning result of the obstacle. According to the method, the unmanned aerial vehicle is used for carrying out semantic segmentation on the ground unmanned vehicles and the obstacles in the environment, and then the planning path is generated, so that one unmanned aerial vehicle can provide obstacle avoidance and planning path providing services for multi
