摘要
提出了在数字散斑时间序列相关三维面形测量中提高计算速度的局部搜索快速算法。通过寻找合理的搜索空间 ,缩小相关计算的范围 ,从而减少相关计算的次数 ,达到了提高计算速度的效果。本文介绍了快速算法的基本原理 。
A method of increasing the calculation speed for shape measurement by digital speckle temporal sequence correlation is presented in this paper.The method is named as regional searching fast algorithm.Through searching for appropriate region,the scope between which the correlation calculation implemented is narrowed,then the times of the calculation is lessened.Thus the calculation speed can be increased in evidence.In this paper,the basic principal of the fast algorithm is proposed,and the application of 3D shape measurement for complex objects is also given.
