摘　　要：已知三视图极值点和三视图划分点,提出了建立各分视图坐标中心及局部坐标系的方法。给出了两种算法:坐标中心通用求解算法和原点取整平移算法。采用ObjectARX的选择集函数及视图变换建立了各分视图的局部坐标系,为后续的图形正误判断或三维重建作了准备。It is supposed that the extreme points of three views and the center point of views-dividing are given. Then the method of establishing the origin of coordinate and coordinate system of sub-view is presented. Two algorithms are given, i.e. Finding Coordinate Center General Algorithm （FCCG） and Origin Point Integrating and Linear-Moving Algorithm （OPIL）. By using selection functions in ObjectARX and views transformation method, the local coordinate system of each sub-view is established.
