Research on Road Traffic Accident Scene Investigation Technology Based on 3D Real Scene Reconstruction

Road traffic accident scene investigation is the basis for road traffic accident processing, which carries important significance for comprehensively analyzing the cause of the accident, and then improving road traffic safety in a targeted manner. Traditional road traffic accident scene investigation methods have disadvantages of long time consumption, difficulty in re-investigation and low precision. In view of this, the paper explores the technical method of road traffic accident scene investigation based on 3D real scene reconstruction technology. The UVA tilt photography process model and 3D model construction method are proposed for different types of accident scene investigation, and the accuracy inspection method is designed for accident scene investigation & measurement based on real 3D model. The model construction and accuracy verification are carried out based on specific accident cases. The research shows that the road traffic accident scene investigation based on the real 3D model can meet the investigation accuracy requirements, which provides efficient and realistic reproduction of the accident scene, and can be used to assist in accident scene investigation.
