摘要

机载超声触觉显示器(AUTD)是一种能在人体皮肤上产生振动触觉的触觉显示器。将AUTD与投影相机系统相结合，可以在3D空间中呈现物理对齐的同步视觉和触觉刺激。为了保持尽可能真实的同步感觉，需要在AUTD和投影-摄像机系统之间进行精确的空间校准。因此，本文提出了一种利用毛皮材料识别相机坐标系中AUTD输出焦点的AUTD系统标定方法。该方法简化了标定过程，标定误差为2.63 mm。

Spatial Calibration of Airborne Ultrasound Tactile Display and Projector-Camera System Using Fur Material

Airborne Ultrasound Tactile Displays (AUTD) are tactile displays that can generate vibrotactile sensation on human skin. Combining an AUTD with a projector-camera system, it is possible to present synchronous visual and haptic stimuli that is physically aligned in the 3D space. To maintain the synchronous sensation as realistic as possible, an accurate crucial to spatial calibration between the AUTD and the projector-camera system is required. This paper thereby proposes a calibration method for the AUTD system by utilizing fur material to recognize the output focal points of an AUTD in the camera coordinate system. Our method simplifies the calibration procedure with calibration error of 2.63 mm.
