本文提出了散斑载波法的图象处理方法。针对带有方向性的各种散斑条纹图,设计了一种简单、迅速的空间滤波器,以消除斑点效应,并用计算机实现了条纹倍增。通过一个实例,说明了散斑载波图的采集、处理、计算全过程,并验证了结果的正确性。 In this paper, the speckle carrier method image processing method is proposed. Aiming at the various speckle fringe patterns with directivity, a simple and rapid spatial filter was designed to eliminate the speckle effect. The stripe doubling was realized by computer. An example is given to illustrate the whole process of collecting, processing and calculating speckle carrier images, and the correctness of the results is verified.
