Abstract

The present application discloses a driving trajectory generation method, device, electronic device and storage medium, and relates to the field of automatic driving. The specific implementation scheme is: determining the target Bezier curve corresponding to the first line of the roundabout scene, the first line being the line that does not enter the roundabout; determining the loop curve corresponding to the second line of the roundabout scene, the first line being the line that does not enter the roundabout The second route is a route within the roundabout; the driving trajectory of the roundabout scene is generated according to the target Bezier curve and the circular curve, which can effectively improve the driving trajectory generation efficiency of the roundabout scene and improve the generation quality of the driving trajectory.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of automatic driving technology, and in particular to a driving trajectory generation method, apparatus, electronic device, and storage medium. Background technique [0002] Due to the complexity and diversity of real traffic scenarios, large-scale simulation testing has become an indispensable part of the iterative process of autonomous driving algorithms, and manual editing of scenarios is one of the important components of simulation testing. [0003] In the related art, manual editing is usually used to add waypoints, so as to assist in generating the driving trajectory of the roundabout scene. [0004] In this way, the generation efficiency of the driving trajectories of the roundabout scene is not high, and the generated driving trajectories are not smooth, resulting in low quality of the generated driving trajectories.
