Abstract

The invention provides a vehicle trajectory determination method and device, electronic equipment and a computer storage medium. The vehicle trajectory determination method comprises the following steps: acquiring position features and motion features of a target vehicle; matching a target road mode from each preset road mode based on the position features and the motion features, wherein the roadmode is a mode obtained by preprocessing historical traffic flow data acquired by a roadside camera and clustering based on the preprocessed historical traffic flow data; calculating a regional constraint point based on the track tail end of the target road mode; generating a candidate track set based on the regional constraint points; and determining a target trajectory from the candidate trajectory set according to the motion model of the target vehicle. According to the embodiment of the invention, the track of the vehicle can be determined more accurately.

Description

technical field [0001] The present application belongs to the technical field of intelligent transportation, and in particular relates to a vehicle trajectory determination method, device, electronic equipment and computer storage medium. Background technique [0002] At present, bicycle intelligence has realized most traffic scenarios, but it has its own limitation of limited perception of the surrounding environment. Most of the trajectory prediction algorithms in the field of autonomous driving are based on the real-time acquisition of vehicle status information by vehicle-side sensors to predict future vehicle driving trajectories. The implementation of the above algorithms mostly relies on the real-time vehicle state data of the vehicle-side sensors, and the global perception range of the self-driving vehicle to the road is limited, and errors in the perception of the surrounding environment due to occlusion and other reasons are more likely to occur. [0003] Therefor...
