Accuracy Comparison of Fringe Projection Technique and 3D Digital Image Correlation Technique

Abstract

Fringe projection technique and 3D digital image correction technique are widely used in experimental mechanics field for 3D shape and deformation measurements. In spite that the two techniques have fundamental similarities, they also have considerable differences. This paper presents an experimental comparison of the two techniques in terms of measurement accuracy. Considering that 3D imaging and 3D printing are very hot topics in today’s world, we believe that the accuracy comparison can be of great interest to the technical community.
