AI Technical Summary

Technical Problem

Existing technologies cannot guarantee accurate matching of the same area reported by different vehicles at different times, especially in autonomous driving, where the polygons of the areas detected by vehicles may be inconsistent at different times, leading to chaotic area matching.

Method used

By acquiring the regional information reported by different vehicles at different times, the unique identifier code of the centroid of the region polygon is determined. Combined with the relative position code of the surrounding map elements, the coding algorithm version number and map version information are used for coding to achieve accurate regional matching.

Benefits of technology

This improved the accuracy of regional matching reported by different vehicles at different times, avoided regional confusion, and enhanced the stability and reliability of the autonomous driving system.

Abstract

The application relates to a region matching method, device, equipment and storage medium. The main technical scheme comprises the following steps: obtaining region information of a specific region reported by different vehicles at different time points, wherein the region information comprises a region polygon and region coordinates of the specific region; determining a centroid unique identification code of the region polygon according to the region coordinates; obtaining element information of a plurality of map elements around the specific region, wherein the element information comprises element coordinates of the map elements; determining a relative position code of the map elements and the centroid of the region polygon according to the element coordinates and the region coordinates; and matching the specific region reported by different vehicles at different time points according to the centroid unique identification code, the relative position code of the map elements and the centroid of the region polygon and current coding information. The application can ensure accurate matching of the same region reported by different vehicles at different time points.
