提出一种新的数字散斑照相计量方法， 该方法将ＣＣＤ和计算机相结合， 在自然光照明下对被测量物体照相， 通过一种快捷的图像处理技术， 直接提取出物体变形信息。突破传统光测的激光照明及傅里叶变换模式， 实现光测量技术真正自动化。
A new digital speckle photogrammetry method is proposed. This method combines CCD and computer to take pictures of the object to be measured under the illumination of natural light, and directly extracts the object deformation information through a fast image processing technology. Break through the traditional optical measurement of laser lighting and Fourier transform mode, to achieve true optical measurement technology automation.
