| 摘 要： | 首先建立了相机的三维摄影测量模型,用于轮胎印迹的准确勘测和建模。然后建立了车辆运动及碰撞过程中的动力学模型,用以模拟车辆在碰撞前、碰撞过程及碰撞后的运动轨迹,和摄影测量得到的轮胎印迹模型比较,采用轨迹优化的方法实现交通事故在计算机上的三维模拟再现。最后通过在典型事故再现中的应用阐述此方法的应用价值。

| Abstract: | First,a model for 3-D photogrammetry is built for the measuring and modeling of tire marks.Then the vehicle movement and collision dynamics models are set up to simulate the movement trajectories of vehicle before,during and after impact,which are compared with the tire mark model obtained by photogrammetry.Trajectories optimization method is used to realize 3D reconstruction of traffic accident on computer.Finally the application to a typical accident case is given to verify its effectiveness. |
