| Abstract: | A method called Digital Speckle Correlation Method of non-contact strain measurement based on digital image processing is introduced. The method has been proved to be reliable by experiment. DSCM has its own advantages of full-field, high-accuracy, easy-operation. So it has good perspective for application in engineering material testing. Thereby, the development of DSCM expand application field for photo-mechanics and present a new prospect for different strain measurement. |
