Plant protection robot autonomous navigation path planning system and method

The invention discloses a plant protection robot autonomous navigation path planning system and method, and relates to the technical field of plant protection robots. The problems that when an existing plant protection robot conducts orchard operation, positioning is not accurate, the obstacle avoidance capacity is poor, and the operation efficiency is low are solved. An autonomous navigation path planning system for a plant protection robot comprises a path planning unit, an autonomous navigation unit, an automatic obstacle avoidance unit and an advancing braking unit. The operation path of the robot is precisely planned through the path planning unit, autonomous navigation and intelligent obstacle avoidance are achieved through the vision assisting device, the operation efficiency and safety of the plant protection robot are improved, the plant protection robot can operate according to the optimal path through the autonomous navigation unit and the automatic obstacle avoidance unit, the operation efficiency
