中文摘要：

变形车辆测量是道路交通事故再现的重要基础性工作。建立基于普通数码相机的事故变形车辆自标定三维重建模型，可以避免在现场设置标定物，有利于提高变形车辆的勘测效率和三维重建设备的使用方便性。研究了基于基础矩阵估计的事故变形车辆摄影图像自标定三维模型，并分析了其实现过程。实验表明，自标定三维重建能为事故再现提供详细的车辆变形描述。

英文摘要：

Building a three-dimension reconstruction model for a vehicle crushed in traffic accident based on self-calibration technique and using common digital camera can avoid setting reference object on scene and enhance the efficiency of crushed vehicle survey. In this paper a three-dimension reconstruction model for crushed vehicle photographs is set up and analyzed with self calibration technique based on fundamental matrix evaluation. The test results show that the detailed description on crushed vehicle can be provided using 3 D reconstruction modeling with self-calibration technique.
