| 摘 要： | 本文提出一种在工程上实用的Ｂｅｚｉｅｒ曲线匀化方法。在一定条件下，匀化曲线可按照指定精度逼近（过）原曲线的型值点列。文中首先介绍了基于离散与归并方法的匀化条件及实现步骤。对过节（型值）点的曲线归并方法做了进一步阐述。文中所述内容已在ＮＰＵ－１／ＣＡＤ－ＣＡＭ系统软件中实现和应用。

| Abstract: | This papor intreduces a practical method of Bezier curve uniforming for approximating given da-ta points on origual curve. The conditions and realization procase of curve uniforming are prasented ,themerging alsorithm for two Bezier curves is given in detail. The methfor and tectuiiques prasented in thispapor have been applied in NPU-1 /CADCAM system and surface medeling of complex parts. |
