Abstract

The invention provides a lane sideline automatic extraction method and a lane sideline automatic extraction system based on a laser point cloud. Through automatically extracting lane sideline data elements which are very important to unmanned driving in a certain accuracy according to reflection strength of each laser point according to the reflection strength of each laser point in a high-precision electronic navigation map data element production process based on the laser point cloud that is acquired by a mobile measurement vehicle, basic lane shape data are supplied for subsequent lane-grade high-precision map, thereby improving lane sideline data element acquisition efficiency, lane sideline data element production efficiency and accuracy. Furthermore the lane sideline automatic extraction method and the lane sideline automatic extraction system greatly improve production efficiency of the lane-grade high-precision map.

Description

technical field [0001] The invention relates to a method and system for automatically extracting lane sidelines based on laser point clouds, which belong to the intersection field of navigation and electronic maps. Background technique [0002] With the rapid popularization of automobiles, there are more and more traffic accidents every year, and the driving safety of automobiles has become a very urgent problem. In the active safety technology of automobiles, the prior information of high-precision spatial maps is effectively used, Avoiding some potential risks in advance is a very important active security research and application direction. At the same time, research on next-generation autonomous driving technology is also in full swing. In driverless technology, high-precision map information is introduced and applied, and the prior information of high-precision spatial maps is used to effectively fuse with information from other sensors. , Complement each other, so as ...
