Abstract

The invention discloses a point cloud-based positioning method, device and electronic equipment. The method comprises the following steps: after receiving current frame point cloud data, determining the previous frame point cloud data of the current frame point cloud data according to an environmental map corresponding to an object to be positioned; performing primary matching on the current framepoint cloud data and the previous frame point cloud data according to positioning azimuth information of the previous frame point cloud data; determining positioning azimuth information of the current frame point cloud data according to an initial matching result of the current frame point cloud data and the previous frame point cloud data; positioning the object to be positioned according to thepositioning azimuth information of the current frame point cloud data. By using the scheme of the invention, the object to be positioned can realize the functions of real-time positioning and mappingeven when no satellite positioning signal exists, and the acquired multi-frame point cloud data can be used to realize accurate positioning of a robot.

Description

technical field [0001] The invention relates to the technical field of intelligent robots, in particular to a point cloud-based positioning method, device and electronic equipment. Background technique [0002] With the development of science and technology and the continuous improvement of people's requirements for the quality of life, intelligent robots gradually appear in people's daily life, such as cleaning robots, industrial robots, service robots, robots that carry goods in warehouses, etc. In order to understand the working conditions of the robot, it is necessary to locate the robot in real time, so as to obtain the walking route and location of the robot. [0003] However, the inventor found in the process of realizing the present invention that most existing robots use satellite positioning technology for positioning when they work indoors. However, when the robot works in a working environment without satellite positioning signals, its positioning function canno...
