【摘要】 利用产品原形的三维测量数据,通过逆向工程设计新产品、改进或生产旧产品的过程中,曲线拟合及曲面重构是关键。采用B样条曲线拟合及B样条曲面重构,曲线更改灵活,曲面连接光滑,在逆向工程中具有广泛的实用性。更多还原

【Abstract】 Curve and curved surface fit is the key in reverse engineering.A new method is presented in the paper that B-splines is used as an analysis tool to fit curve and rebuilt curved surface according to measured data on 3-dimensions from primary shape of mechanical products.Advantage of the new method presented in the paper is smooth of curve and curved surface fit and easy in revising.更多还原
