本文提出了一个位置自由的接口系统,使用户能够输入和获取信息的环境中的任何地方与投影仪相机系统。在图像中检测到的挥手被用作启动系统的提示,以将基于用户的操作意图的手势与其他日常生活动作区分开,并指定用户的手的位置。基于背景差分法和肤色提取相结合的方法实现了手势检测。此外,我们还重点研究了每个像素的亮度值的变化。使用粒子滤波算法跟踪用户的手。用户用他/她的手在环境中的平面上自由地指定投影区域。安装在摇摄-倾斜单元上的投影仪根据用户的指定投影信息。然后,使用简单的模板匹配来检测用户的指尖,并且他/她与投影信息交互以在没有任何设备的情况下输入命令。作为应用之一,我们开发了一个界面系统,在日常生活场景中直观地操作电器(电视)。
This paper proposes a position-free interface system that enables a user to input and obtain information everywhere in the environment with a projector-camera system. Hand-waving detected in the image is used as a cue to start the system, to distinguish gestures based on the user's intension of operation from other daily-life motions, and to specify the position of the user's hand. Hand-waving detection is implemented based on combination of background subtraction method and skin color extraction. In addition, we focus on changes of brightness value in each pixel. The user's hand is tracked using a particle filter algorithm. The user designates the projection area freely on a plane in the environment with his/her hand. The projector mounted on a pan-tilt unit projects information according to the user's designation. Then, the user's fingertip is detected using simple template matching and he/she interacts with the projected information to input commands without any devices. As one of applications, we have developed an interface system to operate electrical appliances (TV) intuitively in a daily life scene.
