Path planning method and system for inspection robot

The invention discloses an inspection robot path planning method and system. The method comprises the following steps: acquiring and preprocessing point cloud data of a working environment of the inspection robot, and constructing a point cloud picture; establishing an initial population based on a KOA algorithm and completing initialization by adopting the point cloud atlas, determining a starting point and an ending point of an inspection task, iteratively updating positions of individuals in the initial population in a search space and searching for an optimal position, selecting an optimal individual based on a tournament selection strategy, and completing inspection of the inspection task. Combining the optimal positions of the optimal individuals into a global path of the inspection robot between the starting point and the terminal point; obstacle data of a working environment are obtained in real time, obstacle avoidance action of the inspection robot is set, a safe time interval is determined accordin
