当今社会交通事故频发,因为事故责任认定引发一些争议屡见不鲜,现场勘查人员对事故现场进行拍照固定和实地勘查测量,运用成像透视测算法和图像重合法,利用Photoshop CS4软件,可以解决部分交通事故责任认定问题。本文通过一起交通事故案例来具体说明,运用上述方法分析,得出前方车辆骑线停车应当负主要责任的鉴定意见。结果表明,成像透视测算法测得数据精准,图像重合法可以作为参考。

A growing number of traffic accidents have occurred in recent years. The determination of the main liability in traffic accident will cause controversy. Crime scene investigators need to fix the scene of the accident by photography and field survey measurement. However, some inaccuracies and omissions may occur when taking a photograph due to many reasons and thus cause some problems in determination of traffic accident liabilities. By applying imaging perspective measurement method and image superposition method with Photoshop CS4 (Referred to as PS) software, it can solve part of these problems. We take a traffic accident occurred in Shaanxi province for example to illustrate. When the crime scene investigators took a photograph at the scene of the accident, they missed some details, which made it difficult to determine the liabilities. Then the methods mentioned above was used and the results indicated that the car parking between the slow lane and the emergency lane should be mainly responsible for the accident. The experimental results demonstrate that imaging perspective measurement method can be accurate and the image superposition method can provide a reference. The actual application should also depend on the specific situation.
