Abstract

The embodiment of the invention relates to the field of computer vision, and discloses a construction method of a laser point cloud map, a terminal and a readable storage medium. The laser point cloud map construction method comprises the steps that in the moving process of a terminal, a pose information set of the terminal and a point information set of the surrounding environment are obtained, point information is used for representing coordinate position information of points, the point information set is obtained through scanning of a single-line radar in a first plane scanning mode, and a first plane intersects with a plane making contact with the terminal in the moving process; and a point cloud map of the surrounding environment is constructed according to the pose information set and the point information set. According to the embodiment, the cost of constructing the point cloud map of the surrounding environment of the terminal can be reduced, and the accuracy of the determined point cloud map is ensured.

Description

technical field [0001] The embodiment of the present invention relates to the field of computer vision, in particular to a method for constructing a laser point cloud map, a terminal and a readable storage medium. Background technique [0002] With the continuous advancement of science and technology, various intelligent terminals such as driverless cars, intelligent robots, and intelligent wheelchairs have emerged. During the mobile process of the smart terminal, it is usually necessary to construct a point cloud map based on the point cloud data obtained by the lidar, and then perceive objects in the surrounding environment based on the point cloud map, or to avoid obstacles based on the point cloud map. [0003] The inventors have found that there are at least the following problems in related technologies: At present, the point cloud data of the surrounding environment is usually obtained based on multi-line lidar, but multi-line lidar is relatively expensive and the cos...
