Non-rigid image Reconstruction of 3 d Motion Simulation Optimization Model

  • 摘要: 现有的基于幂因式分解法非刚体三维运动重建算法,对不连续运动帧进行变换矩阵求解较为复杂,并且该方法的重建误差较大.为了解决这一问题,提出一种基于改进幂因式分解法的非刚体三维图像运动重建算法,在传统算法的基础上针对非刚体运动中产生的不连续性,加入了结构连续性约束,再通过把运动矩阵分解为加权系数矩阵和旋转矩阵两部分,利用最小二乘法分别迭代求解加权系数、旋转矩阵和形状基,完成重建.最后利用真实动态图像序列对算法进行试验验证,试验结果表明了改进算法的有效性和精确性.

     

    Abstract: Based on the existing power factorization method of three dimensional rigid body motion reconstruction algorithm, the discrete motion frame to carry on the transformation matrix to solve more complex, and the reconstruction error of the method. To solve this problem, this paper puts forward an improved power based on factorization method of three-dimensional image non-rigid motion reconstruction algorithm, on the basis of the traditional algorithm for non rigid motion of discontinuity, joined the structure continuity constraint, then through the motion matrix weighted coefficient matrix and the rotation matrix is decomposed into two parts, respectively using the least squares iteration weighted coefficient, rotation matrix and shape, to complete the reconstruction. The algorithm to make use of the real dynamic image sequence test, test results show the effectiveness and accuracy of the improved algorithm.
