Abstract

In tele-communication via WAN, the existence of participant by transmission of a video in real scene is important. In addition, we consider that non-verbal communication such as eye-to-eye contact and gesture play an important role. In order to realize realistic communication between remote places, the display of video image in remote site with the large-scale screen is effective. However, the video image by wide-area display using a projector and large screen is low-resolution, and sufficient presence is not obtained. In this paper, we have constructed tele-immersive environment with scalable tiled displays wall and study on the possibility of realistic communication. We have implemented an application to display high-resolution real video streaming, and realized to display by setting parallel transmission video images captured by 2 sets of cameras on tiled displays wall in remote place. Moreover, 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 in order to realize effective remote communication method between multi-point remote sites.

瓷砖显示墙的逼真通信技术研究

在广域网远程通信中，真实场景中视频传输参与者的存在是非常重要的。此外，我们认为非语言交流，如眼神交流和手势也起着重要作用。为了实现远程场所之间真实的通信，采用大屏幕在远程场所显示视频图像是有效的。然而，使用投影仪和大屏幕进行广域显示的视频图像分辨率较低，存在感不足。本文利用可伸缩的瓷砖显示墙构建了远程沉浸式环境，并对现实交流的可能性进行了研究。我们实现了一个显示高分辨率实景视频流的应用，实现了在偏远地区的平铺显示墙上通过设置2台摄像机采集的视频图像并行传输的方式进行显示。在此基础上，提出了利用图像识别技术对参与者视频的人脸方向进行估计，实现远程通信中传输视频的自动切换，以实现多点远程通信的有效方法。
