Abstract

The invention discloses a mobile robot path planning method. The method comprises the steps that the three-dimensional grid map of a target area is acquired, wherein the three-dimensional grid map is generated according to a three-dimensional point cloud graph; the target location and the current location of a mobile robot are acquired; and according to the three-dimensional grid map, a planned path to the target location is generated. According to the invention, the path planning of the mobile robot is carried out by using the three-dimensional grid map; the height information of an obstacle can be acquired through the three-dimensional grid map; and the obstacle avoidance function of the planned path can be effectively optimized. The invention further discloses a mobile robot path planning device which has the advantages.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, in particular to a method and device for path planning of a mobile robot. Background technique [0002] As a machine system with mobile functions, mobile robots can provide humans with services such as ground cleaning, consignment, and detection, and can also replace humans in some dangerous and harsh environments. It has broad application prospects. [0003] When a mobile robot is moving, it is essential to carry out path planning in order to operate according to the planned path. In the prior art, path planning is generally based on a two-dimensional grid map. The so-called two-dimensional grid map is based on a set of grid data models composed of rows and columns, forming a grid data set consistent with the topographic map in terms of content, geometric accuracy and color, and using the data of each grid to represent the actual geography A digital map image of a fea...
