为增强纳米操作的交互性,本文结合虚拟现实技术,借助力觉反馈设备搭建了基于虚拟3D视觉反馈与虚拟力觉反馈的遥纳操作平台.为确保虚拟环境能够正确反映真实的纳米操作环境,对虚拟模型的碰撞检测和力觉渲染进行了详细设计;同时在力觉反馈设备和虚拟环境之间引入虚拟匹配环节保证力觉交互接口的稳定,增强主端控制模块的协调性.为实现准确的纳米操作,采用基于兴趣区域的图像特征方法提取探针深度信息,快速建立图像模糊度与探针到基底的距离的关系,实现对探针的闭环控制.最后,利用所述的系统平台以及操作方法,完成了单根ZnO纳米线的转移实验.
In order to enhance the interaction of nano-manipulation, this paper combines the virtual reality technology and the force feedback device to build the remote nano-operation platform based on virtual 3D visual feedback and virtual force feedback.In order to ensure that the virtual environment can accurately reflect the real nano-operating environment, At the same time, a virtual match between the force feedback device and the virtual environment is introduced to ensure the stability of the force-sense interaction interface and enhance the coordination of the master control module. In order to achieve accurate Of the nano-operation, based on the region of interest image feature extraction method of probe depth information to quickly establish the relationship between the image ambiguity and the distance from the probe to the substrate to achieve the closed-loop control of the probe.Finally, the use of the system platform and Method of operation, completed a single ZnO nanowires transfer experiment.
