Detecting wings in quadric surface scenes
Greg C. Lee, George C. Stockman · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1992
A method is given for detecting primitive parts of rigid objects whose surfaces are approximated well by quadric patches. From fused range and intensity images, primitives are detected by simultaneously fitting a 2-D object contour and a set of adjacent 3-D surface points. Simulation results show that combined fitting is superior to fitting either range or intensity alone. Experiments with 10 real fused images indicate that a recognition system could be built upon the outlined primitive detection subsystem.
