CONSTRUCTION OF MEASUREMENT SYSTEM FOR CONTINUA BY IMAGE PROCESSING TECHNIQUE

Abstract

In this study, the measurement system for continua by image processing technique is developed. At first, the correlation method for Eulerian coordinate system is updated to trace the large deformation field in Lagragian coordinate more accurately by considering the deformation of the template. Then, the method to correct the measured field by using the volume constraint condition is proposed. Finally, to demonstrate the effectiveness of the proposed system, the system is applied to the measurement of the deformation field of the devices that deforms largely.
