A STEREO-PHOTOGRAMMETRIC METHOD FOR MEASURING DISPLACEMENT FIELDS

A NEW WHOLE FIELD DISPLACEMENT MEASURING TECHNIQUE IS DESCRIBED WHICH IS SUITABLE FOR MEASURING PLANAR DISPLACEMENTS OF ANY TEXTURED PLANE SURFACE. THE METHOD USES ORDINARY PHOTOGRAPHS, TAKEN FROM A FIXED CAMERA POSITION, AND A DEVELOPMENT OF NORMAL STEREO- PHOTOGRAMMETRIC CONTOURING PROCEDURES. DISPLACEMENT MEASUREMENTS OF THE ORDER OF 0.01 MM ARE POSSIBLE ON THE PHOTOGRAPHIC PLATES USED FOR PLOTTING. THE TECHNIQUE IS DESCRIBED IN DETAIL AND ILLUSTRATED WITH DISPLACEMENT CONTOURS OBTAINED FROM A SAND MODEL DEFORMING IN PLANE STRAIN. /RRL(A)/
