【摘要】 介绍了柴油机排气道的逆向造型过程,通过激光扫描仪的非接触测量获取零件表面的云状数据,并由测量数据逐步生成扫描曲线,型值曲线,通过曲面拟合形成光滑自由曲面,最终实现零件的重构。更多还原

【Abstract】 The paper introduces the digitizing reconstruction of diesel engine modeling. Surface cloud data comes from laser scanner.The scan curve, the style curve are created from above measuring data. And then the surface is fitted from the style curve. At last,the part modeling can be reconstructed.更多还原
