Embodiment 1
[0071] The autonomous positioning experiment of the mobile robot lidar in Embodiment 1 of the present invention is shown in FIG. 5 . The positioning experiment was carried out on a grid map with a size of 16.075m×9.9m and a resolution of 2.5cm. It can be seen from Figure 5(a) that a large number of particles are generated near the initial pose estimation (small arrows, the minimum number of particles is 500, and the maximum number is 5000). During the movement of the robot, the particles converge gradually, as shown in Figure 5(b) and Figure 5(c). The big arrow in the figure indicates the running posture of the robot at each moment, and the point cloud is the laser scanning point cloud.
