摘要 纹理的力触觉表达不仅能增强虚拟环境的真实感,还能用于盲人的对环境感知和信息获取。提出了一种新颖的纹理的力触觉建模和表达方法。它是基于图像处理的方法提取纹理表面的几何轮廓,根据物体表面粗糙特性,分别建立法向和切向的接触力模型,通过6自由度DELTA手控器实时作用于操作者,让操作者感受到触摸虚拟物体表面的作用力,从而实现纹理的力触觉表达。进行了实验并证明了方法的有效性。 The texture display is an important issue in virtual reality research. It not only can be used to enhance the realistic of virtual reality system, but also can be used for the blind to acquire the information in the real world. A novel texture display method is proposed. The image processing methods are used to extract the contour of the surface, and the textural features are acquired, then the resultant force （ normal and/or tangential） when sweeping the surface is modeled. The contact force is generated and applied to the operator through the 6 DOF DELTA hand controller in real time. The simulation experiments are carried out and validity and practicability are proved.
