Problems solved by technology

[0004] The existing road information extraction methods mainly rely on manual marking, that is, manually marking the information in the point cloud data. Due to the slow speed of manual marking, the efficiency of map drawing is low
[0005] On the other hand, traditional maps contain rich road information, but the precision of the data is not enough to support autonomous driving scenarios

Abstract

The invention relates to a device and method for acquiring road information from map data. The method includes: acquiring point cloud map data and semantic map data; extracting road information in a semantic map from the semantic map data; acquiring a primary road boundary from the point cloud map data; matching a road boundary in the road information in the semantic map with the point cloud map data to obtain road boundary information of a to-be-generated semantic map; matching lane line information in the road information in the semantic map with the point cloud map data to obtain lane lineinformation of the to-be-generated semantic map; obtaining road information of the to-be-generated semantic map according to the road boundary information and the lane line information of the to-be-generated semantic map. By means of matching of data in a traditional data map with point cloud in high-precision map data, manual annotation is greatly saved, and the map drawing speed is increased.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method, device, computer equipment and storage medium for obtaining road information from map data. Background technique [0002] With the development of science and technology, vehicle automatic driving technology is becoming more and more mature. Vehicle automatic driving technology relies on the cooperation of artificial intelligence, visual computing, radar, monitoring devices and global positioning system, so that the computer can operate without any active human operation. , to automatically and safely operate motor vehicles. [0003] Tasks such as obstacle detection, obstacle prediction, and driving planning in vehicle automatic driving technology generally rely on high-precision map data; the existing high-precision map data is mainly point cloud data collected through lidar, from which Extracting road information is a crucial step. [0004] The existing r...
