摘要
本文介绍了一种通过运用矢量运算方法对平面多边形顶点的凹凸性进行快速自动识别的原理和方法。该方法自动识别准确、可靠性高,已成功地应用于快速成形技术的分层实体制造过程中激光光斑半径的自动实时补偿。
This paper introduces the principle and the method of using the vector operation to recognize concave or convex, vertices of polygon and the recognition speed is very high. The method has been successfully applied to the laser facula radius compensation in the process of rapid prototyping manufacture.
