摘要： 提出一种基于图形理解的几何约束二义性处理的自组织方法。讨论了约束求解过程中的距离约束、角度约束和圆弧约束中的二义性问题,通过有向图的几何约束识别方法,保留了图形变化前几何元素之间的几何和拓扑信息,并以该约束信息为模板,利用多种图元关联约束方法图,唯一确定变参后的求解结果。该方法不需要繁琐的数值求解,避免了求解结果的二义性。

Abstract: A promising approach to processing geometric constraints ambiguity based on the comprehension of graph has been put forward . In the first, the paper discusses the ambiguity of distance constraint,angle constraint and arc constraint . By identifying constraints among graph elements , topology and geometric constraint relations in no-relationship-graph element are set up . Design process is simplified to avoid user operation of alternation pointing out a reasonable solution result . ;;
