| 摘 要： | 针对双目视觉中两摄像机的固定约束关系,提出了基于双目视觉的光束法平差新算法.对传统光束法平差法方程构造过程进行了改进,使每次迭代过程中只需对拍摄的两幅图像中一个摄像机的外参数进行优化,更好地将两个摄像机绑定为一个摄像机,使优化精度更高;新算法中,法化矩阵的维数比传统算法降低了1/2,所以每次迭代计算所需要的时间也会减少...

| Abstract: | In this paper,we propose a new algorithm for bundle adjustment based on the fixed constraints between the two cameras in stereo vision.The new algorithm improves the normal equation of traditional bundle adjustment,and it only needs to optimize extrinsic parameters of one camera in each iteration.The two cameras can be better bounded as one and it can achieve a higher accuracy.The dimension of the matrix in the new algorithm is half of that in the traditional algorithm.Therefore it will reduce t... |
