Inspection robot positioning method, system and equipment

The invention discloses an inspection robot positioning method, system and equipment, and the method comprises the steps: dividing the anchor points of a plant station region into four regions according to the environment characteristics of the plant station region, namely a laser normal positioning region, a plant station positioning gradual change region, a plant station GPS normal positioning region and a plant station narrow region; the current position information of the robot is obtained, so that the anchor point area where the robot is located currently is positioned, and the corresponding positioning strategy is adopted for positioning according to the anchor point area. The robot is accurately positioned in different plant station area environments by adopting laser radar positioning, GPS positioning, IMU and odometer positioning modes with high credibility, and the technical problems that the positioning accuracy of an existing inspection robot is limited by the plant station area environments and t
