Problems solved by technology

[0002] With the gradual intelligentization of Advanced Driver Assistance System (ADAS) functions, the requirements for external environmental information input are getting higher and higher, but (such as vision-based) lane line recognition capabilities have not improved so fast, in some working conditions There will still be short-term missing lane detection (for example, only the left lane line of the current lane and the right lane line of the right lane are detected), so that the wrong judgments in the real world (that is, the constructed road model deviates) cannot be satisfied.

Abstract

The invention relates to a method for constructing a road model, and the method comprises the steps: constructing a lane line pool which comprises one or more historical lane lines; updating the lane line pool based on the matching of the current lane line and the one or more historical lane lines in the lane line pool; and performing lane matching processing on all the lane lines in the updated lane line pool so as to construct the road model. The invention further relates to equipment for constructing the road model, a computer storage medium and a vehicle.

Description

technical field [0001] The present invention relates to the field of building road models, and more particularly, to a method and device for building road models, a computer storage medium, and a vehicle. Background technique [0002] With the gradual intelligentization of Advanced Driver Assistance System (ADAS) functions, the requirements for external environmental information input are getting higher and higher, but (such as vision-based) lane line recognition capabilities have not improved so fast, in some working conditions There will still be short-term missing lane detection (for example, only the left lane line of the current lane and the right lane line of the right lane are detected), so that the wrong judgments in the real world (that is, the constructed road model deviates) cannot be satisfied. Design requirements for more functions. Contents of the invention [0003] According to an aspect of the present invention, there is provided a method for constructing ...
