[0002] As the number of motor vehicles and driver possessions continues to increase rapidly, the increase in traffic density has also led to an increase in minor traffic accidents. If a minor traffic accident is handled improperly, it may cause a "small accident and large traffic jam". There may even be a second accident. Therefore, many cities have implemented rapid handling of traffic accidents that cause only small vehicle damage or minor injuries. In the process of rapid handling of minor accidents, both parties may solve the problem by self-consultation, or take photos and obtain evidence of the final state of the accident site, as the main evidence for the determination of the liability of the accident. However, before the scene is evacuated, if the scene is not photographed in advance, or the shooting effect is not good, the accident may not be determined.

[0003] The patent authorization document with the application number 201210125038.2 publicly discloses a method and system for automatically obtaining evidence for highway traffic incidents, and specifically discloses the steps: The camera ball camera is panoramicly monitored at a predetermined position, and if a violation target is detected, the ball machine Automatically track forensics, and then re-position it at the predetermined position, the dome camera captures the current frame image and detects the violation target. If the target is detected, the similarity between the target image region of the current frame and the corresponding region of the target image is calculated, if the similarity is greater than When the threshold is predetermined, the target area is integrated into the background image and the panoramic monitoring is continued at the predetermined position, otherwise the forensic is automatically tracked.

[0004] The above-mentioned monitoring range of the prior art can only be based on the limited area acquired by the fixed-point surveillance camera, and the monitoring range is too large, and it is difficult to accurately capture the evidence of vehicle violation, especially in the accident-prone area, which cannot be targeted for evidence; further, Field wiring construction and related hardware and equipment support are also required, and the maintenance cost is high.
