中文摘要：

针对传统事故现场测量中存在占道时间长、人为误差大等缺点进行分析,提出了事故摄影测量的方法。首先介绍了三维全景的获取并建立了相机的三维摄影测量模型,用于事故现场几何信息的提取。其次通过对事故车辆运动轨迹分析,建立了车辆运动和碰撞过程中的动力学模型,用于车辆运动轨迹的模拟。通过Pc-Crash仿真,将仿真后车辆运动轨迹与摄影测量获得真实的路面轨迹进行对比,利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,通过对一起交通事故案例的仿真再现,验证了该方法的有效性,并指出其中的不足。

英文摘要：

It researched on disadvantages related to measurement for a long time and high artificial error in the traditional method, photogrammetry is proposed.Firstly, 3D panorama acquisition and model for 3D photogrammetry are used to extraction of geometric information in the accident scene. Secondly,through the analysis of trajectory of accident vehicle, the vehicle movement and collision dynamics models are set up to simulate the movement trajectories. Compared the simulated trajectories with true marks obtained by photogrammetry in Pc-Crash simulation, trajectories optimization method is used to realize 3D reconstruction of traffic accident.Finally, the simulation for a real accident case is given to verify its effectiveness and explain its shortcomings.
