Title:
LANE STRUCTURE DETECTION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/170140
Kind Code:
A1
Abstract:
A lane structure detection method and apparatus. The accuracy of lane structure detection can be improved by means of determining a change in a lane structure according to a change in the distance between a vehicle and a lane boundary. The method comprises: acquiring lane boundary information (S101), wherein the lane boundary information comprises position information of a left lane boundary and a right lane boundary; acquiring position information, respectively corresponding to at least two time points, of a vehicle (S102); determining, with regard to each time point, the distance between the vehicle and the left lane boundary and the distance between the vehicle and the right lane boundary according to the position information, corresponding to the time point, of the vehicle (S103); determining a change in a first distance between the vehicle and the left lane boundary at the at least two time points and a change in a second distance between the vehicle and the right lane boundary at the at least two time points (S104); and determining a lane change on the basis of the change in the first distance and the change in the second distance (S105).
