| Abstract: | 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. |
