Abstract

The invention relates to map construction and application, and belongs to the technical field of map construction. The map construction method comprises the steps of successively collecting road image information on a road by multiple vehicles running on the road, and obtaining locating information at a position point where the road image information is collected; extracting road information from the road image information; uploading the road information and the corresponding locating information obtained by the vehicles through the vehicles; and generating or updating road map information on the road based on the road information and the corresponding locating information of the vehicles.

Description

technical field [0001] The invention belongs to the technical field of map construction, and relates to the construction of a high-precision map based on road image information collected by an image sensor and its application. Background technique [0002] High-precision maps are different from traditional road-level maps, which have more detailed information about roads than road-level maps. High-precision maps are the data basis for automatic driving and an important input for automatic driving systems. They are of great significance for improving the performance of automatic driving. which performed. [0003] The accuracy of existing navigation maps is generally not high, and the entire road is used as an object to provide road information data or issue navigation instructions. This kind of navigation map is called a road-level map, which greatly simplifies the actual traffic environment and can provide The amount of information is small and the accuracy is low. [000...
