Experimental Evaluation of ‘Shape from Shading’ for Engineering Component Profile Measurement

Abstract
This paper examines the application of the ‘shape from shading technique’ for three-dimensional surface geometry measurements and object inspection. The results for diffuse, specular and combined models are presented for a range of components exhibiting flat to highly curved surfaces. A more representative relationship between surface radiance and image intensity has been developed which, when incorporated in the models, is shown to change the accuracy of profile measurement.
