【 摘 要 】

In order to get the interference information extraction aircraft aluminum honeycomb structure defect extraction, reliability of testing. This paper uses image processing technology to find a method about image processing composite, with the help of laser shearography detection method detecting detection. The flaw speckle results show that, after Fourier filtering, unpacking of step by step, linear trend processing of the image, gray scale processing method can extract powder composite suited interference information, effectively improve the reliability of detection of the scattered laser displacement suited, provides a new image processing program to help speckle image processing.
