Abstract

The invention discloses a hybrid navigation method, device and system based on laser radar and light reflection boards. The method comprises the following steps: acquiring point cloud data of the laser radar; calculating pose information of the carrier according to the point cloud data of the laser radar; and formulating a motion strategy, and driving the carrier to move, wherein the step of calculating the pose information of the carrier according to the point cloud data of the laser radar comprises the steps of judging whether the point cloud data of the laser radar includes at least three special data accordant with return signal features of the light reflection boards, if so, calculating pose information of the carrier according to the special data, otherwise, directly calculating poseinformation of the carrier according to the point cloud data. According to the method, the laser radar is cooperated with the light reflection boards in use, the accurate position of the carrier canbe calculated according to the special data with relatively high strength returned by the light reflection boards, the position can be further corrected when the environmental scene is changed hereby,and the light reflection boards can be flexibly distributed according to requirement, so that the distribution density of the light reflection boards is decreased, and a dead corner on which the carrier is lost is not formed.

Description

technical field [0001] The invention relates to the field of robot technology, in particular to a hybrid navigation method, device and system based on laser radar and reflector. Background technique [0002] At present, robot and AGV technologies are booming, and various industrial, commercial, and household robots and AGVs, such as logistics robots, navigation robots, home robots, and handling AGVs, are emerging on the market. In the entire robot system or AGV, navigation technology is one of its most important core technologies. Navigation technology mainly determines the current pose information of the robot through sensor technology, and clarifies the guidance angle, speed and operation of the car according to the destination information. route. The current mainstream solution for various robots on the market is based on lidar, which uses lidar to obtain environmental information to build maps and navigate. However, lidar has the problem of low accuracy in mapping and n...
