用双目视觉方法重建交通事故现场空间点
Two-eyes-visual Method to Reconstruct Measuring Point on Traffic Accident Scene
【摘要】 由于交通事故现场测量对象呈静态特性 ,根据计算机视觉中的双目视觉原理 ,可以使用两幅从不同方位拍摄的事故现场图像对事故现场进行测量。在实现过程中用预制三维方块标定物对拍摄使用的照相机内外参数进行标定 ,求取投影变换矩阵 ,并用基于面积的配准方法进行对应点匹配。模拟事故现场的测量结果表明用该方法对交通事故现场进行测量 ,可为事故再现提供大量数据
【Abstract】 Because the objects measured on accident scene are generally static, they can be reconstructed by using two photographs taken at different position on the accident scene according to the method of two?eyes vision in computer vision Three?dimensional reference object has been used to calibrate the camera,and image has been matched based on area according to the comparability The program has been given on the base of this method It can be used to measure the accident scene
