本文介绍了一种新型的单摄像头投影屏触摸传感系统。为了实现相机图像的触摸感应,需要克服两个挑战。一是建立鲁棒性,防止被投影内容误导的图像处理。二是利用单摄像头图像实现触摸检测和指尖定位。在这项工作中,我们使用斜率视差门控并仅捕获投影屏幕略高于的区域。该选定区域以几何方式设置,以便在触摸时捕获手指的一部分,而在不触摸时不捕获手指。这项研究的一个关键特征是,投影仪可以在相机中启用这种选择性成像功能,同时仍然向用户的眼睛显示正常的投影图像。该投影仪既是用于捕捉系统的可编程光源,又是用于用户的界面显示设备。我们建立了一个原型系统和触摸传感算法,评估了触摸精度,证明了对投影内容的鲁棒性。
This paper introduces a novel touch sensing system for a projected screen with a single camera. To achieve touch sensing with camera image, there are two challenges to overcome. One is to establish robustness against image processing being misled by projected contents. The other is to realize both touch detection and fingertips localization with a single-camera image. In this work, we use Slope Disparity Gating and capture only the region slightly above the projected screen. This selected region is set geometrically so that a part of the finger is captured when touching, and no finger is captured when not touching. A key feature of this study is that the projector can enable this selective imaging capability in the camera while still displaying a normal projected image to the user's eyes. The projector is both a programmable light source for capturing system and an interface display device for the users. We built a prototype system and touch sensing algorithm, evaluated the touch accuracy, demonstrated robustness to a projected content.
