摘　　要：通过研究设计人员在绘图中的绘制行为及习惯,提出了一种笔触语义与几何特征相结合的草图理解技术,目的是建立一个在创意阶段适合概念设计人员的手绘交互界面系统。这种方法按照草绘过程提取笔触类型并分析其中所含的语义特征,通过定义弯曲度阈值、压力度阈值的概念,采用阈值检测来判断和理解草绘笔触类型,将其融入到草绘各个阶段。结果使得不同阶段、不同功能笔触类型得到有效分类和辅助识别,并且草绘过程中可以通过人机交互方式实现草绘稿和规整线稿的转换。实验表明,这种手绘方法既在一定程度上达到了手绘效果,又不妨碍设计者创意思路的延伸,满足了个性化的绘制习惯。Through the study on drawing behavior and habit of designers, the paper gave a sketch understanding method which combined stroke semantic feature and geometric feature. The paper＇ s purpose was to build a hand-drawn interface system for concept design personnel in the creative development research. According to conceptual sketching process, the paper extracted strokes types, and analyzed the semantic features. By the concept definition of ＂bending threshold＂ and ＂pressure strength threshold＂ ,it used threshold detection to determine the strokes types, which could be used into rough stages. The results made different stages, different types of stroke function effectively classified and auxiliary recognized. The designers could choose the way between drafting interface and understanding interface by man-machine interactive function in the sketching process. The test result shows that this kind of method not only can get a hand-drawn effect, but also shall not prevent the designer＇ s crea- tive thinking process and can meet the personalized drawing habit
