摘　　要：复杂形体是工业设计、艺术设计、陶瓷设计中常见对象,可采用NURBS(非均匀有理B样条)曲面、细分曲面、隐式曲面等加以描述,但对其成形过程目前尚无有效的数字设计工具。人们认识、改变外在事物时,主要利用视觉与触觉的感官功能,通过手眼协调设计出新的事物。现有的数字设计系统大多是基于形体数学描述方式的系数调整,缺乏直观性、易用性。提出了、实现一套视觉与触觉相结合数字设计系统,以数码相机和触觉系统为工具,快速实现复杂形体的数字建模。详述了系统原理及组成,并给出了设计实例,验证了方法的有效性。Freeform shape can be represented using NURBS surfaces、implicit surfaces,or others,but how it can be designed easily is still a difficult problem.A new method integrating vsion and haptic is proposed to solve the problem.The integrated system can be looked as the eyes and the hands of a sculp-turer,and its user can easily obtain the main capcility of a sculpturer with aid of the system.During the design process,a reference object is capertured by the vision system,and its digital model is transferred to the hapic system in which the details and skeleton can be changed quickly.The final output is a re-designed freegorm shape.The principles of the system are discussed,and two examples are given to prove the benefits of the new method.
