AI Technical Summary
Technical Problem
Existing methods for updating road signs have low accuracy, rely heavily on manual operation which is inefficient, and lack sufficient two-dimensional image data, leading to inaccurate updates.
Method used
By acquiring multiple road images of the target road segment, 3D reconstruction is performed to generate point cloud information. Then, 3D coordinate transformation and clustering are performed in combination with existing road sign information to update the existing road sign information.
Benefits of technology
It improves the accuracy of road sign updates by using 3D point cloud information to update road signs more comprehensively, thus improving the accuracy and efficiency of the updates.
