Abstract

Nondestructive testing by IR thermography with heat injection has found numerous applications in the industry. However this technique is not always reliable for the inspection of nonplanar objects. The goal of the method presented here is to determine the shape of objects present in the field of view from the corresponding single early recorded IR digital image, in order to first correct distortions due to inspected object shape and second to detect potential subsurface defects.
