Apply digital image technology in material mechanics property test and research and analyze the application process and structure. At material tensile stage, improve previous calibration and matching method based on traditional stereoscopic measurement, improve the accuracy and timeliness of several calibration points, change the factor and accelerate the matching speed combining small included angle to timely and accurately rebuild three-dimensional topography of deformed surface. Beside, measure the displacement field and strain field by using the unilateral camera. Finally obtain the curves of maximum tensile strain and tensile strain rate of strain point VS time. Application of digital image technology in material mechanics property test is key technology to guarantee the accuracy of test result, so it has certain promotion and application value.
