Title:
TRAVELING TRAJECTORY GENERATION METHOD AND APPARATUS, AND COMPUTER DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/012492
Kind Code:
A1
Abstract:
A traveling trajectory generation method and apparatus, and a computer device and a storage medium. The method comprises: acquiring a turning angle and a running distance of a target vehicle within one historical time period (S1); marking angle nodes and an angle peak of the turning angle, wherein the maximum value of the turning angle in one turning direction is the angle peak (S2); marking, according to the angle nodes and the angle peak of the turning angle, a distance node and a turning point on the running distance (S3); performing traveling trajectory simulation by means of the angle node, the angle peak, the distance node and the turning point, so as to generate a simulated traveling trajectory (S4); importing the simulated traveling trajectory into a map for matching (S5); and correcting the simulated traveling trajectory on the basis of the map to obtain a traveling trajectory of the target vehicle (S6). The method can acquire a traveling trajectory of a vehicle in the situation where a GPS signal cannot be used for positioning.
