AI Technical Summary

Technical Problem

Traditional lane binding methods are prone to misjudgment when the lane line curvature changes greatly or the lane width is uneven, and it is impossible to accurately identify the lane where the vehicle is located, resulting in insufficient accuracy of lane binding.

Method used

By obtaining the lane track point coordinates and vehicle coordinates, the vehicle outer envelope range is determined, and the projection distance of the vehicle to the lane corresponding to the lane track point coordinates are calculated. The lane is dynamically selected and bound to the vehicle based on the projection distance and preset binding conditions.

Benefits of technology

It improves the accuracy of lane binding and can accurately identify the lane where the vehicle is located in the case of large changes in lane line curvature or uneven lane width, improving the quality of the intelligent driving data set and the accuracy of decision-making.

Abstract

The invention discloses a lane binding method, device and equipment and a storage medium, and relates to the technical field of automatic driving, and the lane binding method comprises the steps: obtaining a lane track point coordinate and a vehicle coordinate; determining a vehicle outer envelope range according to preset vehicle outer envelope parameters and vehicle coordinates; calculating a projection distance from the vehicle to a lane corresponding to the lane track point coordinate according to a position relation between the lane track point coordinate and the vehicle outer envelope range; and determining a lane meeting a preset binding condition based on the projection distance, and binding the vehicle with the lane meeting the preset binding condition. According to the invention, the accuracy of lane binding can be improved.
