中文摘要：

针对运动车辆在单目视觉下轮廓重构的问题,本文通过特征目标识别的方法解算出无约束运动车辆的运动参数,将无约束运动物体的轮廓重构问题转化成已知约束运动物体的轮廓重构问题,提出了一种基于视频序列的单目视觉下的运动车辆轮廓重构算法.实验结果证明,新算法能够较好地重构出不同大小车辆的3D轮廓,其车辆高度估算值的误差在4%以内.

英文摘要：

To solve the problem of contour reconstruction of moving vehicle on monocular vision, the au-thors propose a new algorism based on video sequence. In this paper, we obtain the motion parametersof unconstrained moving vehicle by solving the characteristic equations, and convert the contour recon-struction problem of unconstrained moving vehicle into the problem of constrained moving vehicle. Ex-periments show that the new algorism can reconstruct contour of different vehicle, and the error of vehi-cle height estimation is less than 4%.
