- 摘要:
- 为了解决三维运动矢量计算的问题，提出一种算法，这种算法是在静态三维重建的基础上用二维图片计算刚体运动的线性方法，利用QR分解求解线性方程的最小均方误差解，迭代来消除离群值，来得到运动矢量.这种算法不需要摄像机标定，实时性好，有利于视频的流畅显示，实验结果表明，此种算法具有一定的鲁棒性.
- Abstract:
- In order to solve a 3D motion vector calculation, a new algorithm was proposed. This algorithm is a linear method that calculates the rigidbody movement from twodimensional views based on the static 3D reconstruction. The QR decomposition was adopted to obtain the minimum mean square error of a linear equation set and an iterative process enables the method to eliminate outliers and thus obtain motion vector. This algorithm does not require camera calibration, and it is realtime, which enables smooth video. The experimental results show the algorithm has good robustness.
