Construction of infrastructure for tele-immersive collaborative work with tiled display wall

在本研究中，我们利用拼贴显示墙技术来研究远程沉浸式协同工作的基础设施技术，即在两个或多个LCD面板上配置有效的广域屏幕系统。作为研究成果，我们提出了通过图像识别技术从参与者的S视频中估计人脸方向来实现远程通信中传输视频的自动切换技术。然后，通过传输多个摄像头采集的视频数据并合成成高分辨率视频图像，构建了在拼接显示墙上实现逼真高分辨率视频图像高速显示的环境。此外，我们还研究了用于远程协同工作的超大规模数字内容的有效显示和控制技术。

In this research, we study on infrastructure technology for tele-immersive collaborative work by using tiled display wall technology which configures effective wide-area screen system with two or more LCD panels. As research results, we have proposed the technique for automatic switching of transmission video in remote communication by the estimation of face direction from participant' s video with image-recognition technique. Then, we have constructed the environment to realize high-speed display of realistic high-resolution video image on tiled display wall by transmitting each video data which captured by multiple cameras and compositing as a high-resolution video image. In addition, we have studied on effective display and control technique for ultra-scale digital contents which used in remote collaborative work.
