Path planning method and device and automatic inspection equipment

The invention provides a path planning method and device and automatic inspection equipment, and relates to the technical field of computers. The path planning method comprises the following steps: determining a first planning path from a starting point to a target point according to a first bionics algorithm; initializing parameters in the ant colony algorithm; determining a plurality of candidate paths according to the pheromone concentration, and determining a path with the maximum current fitness according to the plurality of candidate paths; updating the pheromone increment according to a plurality of candidate paths; updating the pheromone concentration according to the updated pheromone increment and the pheromone volatilization factor, wherein the pheromone volatilization factor is related to the number of iterations or the iteration time; and iteratively executing the steps of path determination, pheromone increment updating and pheromone concentration updating until the maximum number of iterations
