Summary:
Image-based 3D (three dimensional) reconstruction technology has been widely used in many fields. Aiming at the specific scene of road traffic accident, relevant 3D reconstruction materials based on UAV (Unmanned Aerial Vehicle) aerial photography accident scene images have been collected. Moreover, the most popular open source and commercial 3D reconstruction methods are studied and compared. Then the simulated accident images acquired by UAV are reconstructed with the above methods, and the dense point cloud model of the accident site is obtained. Finally, each reconstruction result is evaluated in terms of geometric accuracy. The experimental results show that COLMAP, Altizure and PIX4D methods are more suitable for traffic accident scene reconstruction.
