  • Patent number: 12105522
    Abstract: The present application relates to a multi-sensor-fusion-based autonomous mobile robot indoor and outdoor navigation method and a robot. The method includes: acquiring inertial measurement data and three-dimensional point cloud data of a robot at a current position; determining a pose change of the robot based on the inertial measurement data of the robot at the current position; performing distortion correction on the three-dimensional point cloud data of the robot at the current position based on the pose change of the robot; and matching the three-dimensional point cloud data after the distortion correction with a navigation map, to determine the current position of the robot. With the method, the robot can be accurately positioned.

  • Patent number: 12019453
    Abstract: The present application relates to a multi-sensor-fusion-based autonomous mobile robot indoor and outdoor positioning method and a robot. The method includes: acquiring GPS information and three-dimensional point cloud data of a robot at a current position; acquiring, a two-dimensional map corresponding to the GPS information of the robot at the current position; projecting the three-dimensional point cloud data of the robot at the current position onto a road surface where the robot is currently moving, to obtain two-dimensional point cloud data of the robot at the current position; and matching the two-dimensional point cloud data of the robot at the current position with the two-dimensional map corresponding to the GPS information of the robot at the current position, to determine the current position of the robot.
