摘要
建筑图纸中的建筑对象多而繁杂,包含孔洞结构的地板属于复杂且较难识别的建筑对象。采用ObjectARX可以实现对CAD图形数据库的访问,进而从建筑图纸中提取信息。经过数据预处理后,通过编写对地板的自动识别算法,能够对地板各个组成部分的轮廓进行提取,最终输出有序坐标序列点集,以供三维引擎使用。
There are many and complex architectural objects in architectural drawings,and the floor containing the structure of holes is a complex and difficult to identify architectural object.ObjectARX can be used to access the CAD graphics database,and then extract information from architectural drawings.After data preprocessing,by writing an automatic recognition algorithm for the floor,the contours of each component of the floor can be extracted,and finally an ordered coordinate sequence point set is output for use by the 3D engine.
