摘　　要：基于CATIA数模的CMM测量软件开发过程中,对于采用非CAA模式的开发者,必须解决测量点在绝对坐标系下与测量坐标系下的坐标转换算法问题。为此,本文借助VBA工具对CATIA测量点实现坐标转换的算法进行了深入研究,总结了8种三维线性变换矩阵,以供开发者进行进一步研究和验证。During the development of CMM measurement software based on CATIA digital modeling,developers who do not use CAA mode must solve the problem of coordinate conversion algorithm between measurement points in absolute coordinate system and measurement coordinate system.Therefore,this article introduces VBA tool used to conduct deep study on the algorithm of coordinate conversion for CATIA measurement points,and summarizes 8 kinds of 3D linear transformation matrices for developers to conduct further study and verification.
