AI Technical Summary
Technical Problem
The accuracy of road sign point cloud generation in existing technologies is low, especially in low-cost solutions.
Method used
By acquiring multiple road images on the target road, feature matching and 3D reconstruction are performed to obtain the road plane in the image. Based on these planes, a road marker point cloud in a point cloud coordinate system is generated.
Benefits of technology
This improves the accuracy of road sign point cloud generation and ensures accurate road surface calculations, thereby generating more accurate road sign point clouds.

Abstract
The application provides a road sign point cloud generation method and device. The road sign point cloud generation method comprises: acquiring a plurality of first road images on a target road; acquiring an image road plane of each first road image in a point cloud coordinate system and road sign pixel points on each first road image; fitting based on the image road planes of the plurality of first road images to obtain a fitted road plane; and projecting the road sign pixel points on each first road image to the fitted road plane to obtain a road sign point cloud in the point cloud coordinate system. The application can improve the accuracy of road sign point cloud generation.
