摘要
为解决设计图纸差异分析问题,提出一种基于CAD电子图纸技术的自动比对算法。通过CAD技术提取图纸图元,使用快速排序和分组算法对两张图纸的图元进行快速筛选和对比,对图纸间的增加、修改、删除情况进行快速判断和渲染。实验结果表明,此算法识别准确,处理速度快,有较高的适用价值。
To solve the problem of analyzing different drawings,an automatic comparison algorithm for CAD drawings is proposes.It extracts the entities of drawings using CAD technology,uses the quick-sorting algorithm and grouping algorithm to select and compare the entities in two drawings,and then quickly judges and renders the changes of adding,modifying,and deleting on drawings.The experimental results demonstrate this method has good recognition accuracy,rapid processing speed and high practical value.
