On views separation and coordinate standardization , a coordinate axis projection - based approach and an image scanning - based approach are proposed for views separation , the former reduces the compare times of 2d primitive in drawings and raises the efficiency simultaneously , the latter can separate free nember views of engineering drawing accurately and it has no correlation with complexity of primitive , then , two sets of 2 . 5d coordinate systems are introduced as intermediates to relate the 2d original drawing system to the 3d space projection coordinates anfd a formal technique is developed for constructing transformation matrices between coordinates
3 .在工程图视图分离和坐标规格化方面,提出了改进的坐标轴投影分离算法和基于图像扫描的视图分离算法。前者减少了工程图中二维实体的比较次数,提高了运行效率;后者可以准确分离具有任意视图数目的工程图,且算法的稳定性与边界复杂度无关。通过引入二维半中间坐标系推导出了从绘图坐标系到空间投影坐标系转换的转换算子并给出了基于转换算子的坐标规格化算法。
