Three-dimensional Computer Vision Techniques for Full-field Surface Shape Measurement and Surface Flaw Inspection 920246

Two three-dimensional computer vision schemes will be presented, one for diffusely reflective surfaces, and the other for specularly reflective surfaces. Both techniques are based on the marriages of optical techniques and computer image processing algorithms which allow full-field precision measurement of surface depth. The techniques can also be used for inspecting surface quality of car bodies.
