【Abstract】 Extracting geometric parameters of quadric surface from measured data is an important problem in reverse engineering of mechanical parts. It helps understand the designer’s intention and improves accuracy and efficiency of parts reconstruction. This paper proposed to use immune algorithm based on real-number-coding to extract quadric surface. Numerical experiments and comparing with other algorithm show the high efficiency, robustness and accuracy of this algorithm. A new method is offered to extract quadric surface based measured points for reverse engineering.更多还原
