Abstract

The projection of structured light is a technique frequently used in computer vision to determine surface structure of scene objects. In this paper, higher level features are extracted from the images and used for a direct estimation of second-order object surface models. The algorithm is based upon a predictor-corrector approach which utilizes an initial estimate for the surface parameters, followed by iterative parameter refinement. A predicted passive image is generated using the current surface parameter estimates and significant features are extracted and compared with those in the true passive image. The extimated surface parameters are corrected based upon feature disparities. The algorithm is well-suited for a particular vision task involving recognition of cylindrical drums. In computer simulations and laboratory experiments, the algorithm was found to converge quickly and to yield accurate results.
