Spring Semester

In the spring semester, we designed and implemented the overall system for updating HD maps with video from vehicles. We adopted COLMAP for accurate scene reconstruction and camera pose estimation.  Then a 3D-to-3D similarity transformation is estimated to project traffic sign positions in COLMAP coordinates to HD map coordinates. Finally some post-processing steps are designed to ensure consistent projection results and to remove duplicate detections.
