Today, the county police authorities deal with road traffic accidents and more to measuring wheel as the main measurement tool. The police officer in the field to measure the relevant data and draw the traffic accident scene sketch is completed, and then return to the unit to operate Microsoft Visio software or Easy Street Draw and other computer graphics software to computerize the traffic accident scene sketch and upload, which inevitably exists human error, and can only be presented in 2D way restrictions. The scene sketch of the traffic accident is an extremely important part of the accident handling. The factors such as the drawing ability, the search technique and the subjective judgment of the police officer are directly related to the good and bad of the accident scene sketch, which in turn affects the accident analyst to make a correct report. Affect the interests of the parties to the traffic accident is huge. In recent years, unmanned aerial vehicles (UAV) for aerial imaging applications becomes more and more widely. The aerial photography of UAV which is equipped with high-resolution cameras can provide Point Cloud, Digital Surface Model (DSM) and Orthophoto image for the planning of traffic engineering improvement and analysis of driving behavior simulation. This study is based on using multi-axis aircraft in unmanned aerial vehicles for traffic accident dealing , which is discussing the performance of multi-axis aircraft and simulation reconstruction function of Pix4Dmapper and Comparing the benefits and the difference between the traditional scene of the accident. It is expected to 3D simulation of traffic accident scene with shoot of the multi-axis aircraft will be more realistic than 2D sketch. On the other hand, it is hoped that the multi-axis aircraft can be used as a measurement tool to reduce the man-made error caused by the use of the measuring wheel. Finally, it is hoped that the study will be used as a reference for the current traffic accident investigation.
