同时开发设计了交通事故现场图绘制技术与事故再现技术一体化的数据结构框架。

And the same time developed the construction of data frame for the road traffic accident spot diagram drawing technology and the integration accident reappearance technical.

目前我国道路交通事故现场的数据采集、绘制现场图以及分析事故原因基本上还是靠手工进行，费时费力且难以保证其准确性。

At present, the traffic accident spot data collecting, graph drawing and reason analyzing is still transact by hand, it is difficult and uncertainty, therefore it takes much more time.

然后在此基础上，开发了汽车碰撞事故模拟再现软件系统，实现了现场图的输入和碰撞点坐标的自动计算，并可以显示事故发生的全过程。

Then, the road traffic accident reconstruction and simulation system is developed. This system is able to input the traffic accident scene information and simulate the traffic accident whole process.
