Abstract

The invention relates to the positioning technology field and especially relates to a global positioning system and a method based on a laser radar. The system comprises a data acquisition module, a data processing module, a global coarse positioning module, a local fine positioning module and a positioning feedback module. In the invention, the laser radar adopts a 3D laser radar. Compared with aprevious 2D laser radar, the 3D laser radar can acquire a lot of point cloud data information, can acquire environment information of a vertical plane and can comprehensively include the environmental information so that more data is acquired. By using the system and the method, processing is convenient and the data can be visually visualized.

Description

technical field [0001] The present invention relates to the technical field of positioning, and more specifically, to a global positioning system and method based on laser radar. Background technique [0002] With the development of the times, lidar is more and more used by people. Lidar is used in navigation, positioning, maps, etc. There are also many methods for positioning, such as camera positioning, 2D lidar positioning, 3D lidar positioning and so on. However, the current 3D lidar positioning does not have a relatively fast and effective global positioning method, and now 3D lidar positioning is used in many places. Contents of the invention [0003] In order to overcome at least one of the above-mentioned defects in the prior art, the present invention provides a laser radar-based global positioning system and method. By using 3D laser radar to collect data, the collected data is processed, and global rough positioning The method draws a part of data from the gl...
