Mobile video sensing over wireless network and image enhancement

本项目旨在通过无线网络远程控制的移动平台获取图像的现实化。研究中所做的工作都列在下面。一个移动平台是由一个汽车轮椅制造的。控制系统是基于PC上的，移动平台是由PC上的命令控制的。方向和运动的速度都被控制了。通过局域网和PHSCommunication系统对移动平台的控制是由基于TCP/IP协议的移动平台远程控制的。国家湿地公园Video压缩方案已开发用于移动平台上的基于PC的视频通信，可由远程控制网站在移动平台上捕获视图，该移动平台视频压缩方案基于空间变体采样，以更详细的方式显示中心区域和更少的细节。通过远程控制的移动平台通过PHS无线网络进行图像采集的实验图像通过PHS无线网络捕获了摄像机上的移动平台。移动平台是由远程用户看到被传送的图像控制的。图像增强图像处理方案已开发以增强图像的质量，其中使用了多个不同聚焦的图像，并产生了对图像的各种特殊影响，包括所有焦点图像。

This projects aimed at realization of image acquisition using mobile platform remotely controllable over wireless network. The works done in the research are listed below.・ Building mobile platformA mobile platform was made from a motor wheelchair. The control system was based on PC and the mobile platform was controlled by command on PC. The direction and the speed of the movement was controlled.・ Control of the mobile platform via LAN and PHSCommunication systems was made so that the mobile platform was remotely controlled under LAN or PHS network based on TCP/IP protocol.・ Video compressionVideo compression scheme was developed for the PC based video communication on the mobile platform by which the remote control site was able to capture views around the mobile platform The video compression scheme was based on spatially variant sampling, which images the center area in more detail and the peripheral in less detail.・ Experiments of image acquisition by remote controlled mobile platform via PHS wireless networkImages were captured which were transmitted from the camera on the mobile platform via PHS wireless network. The mobile platform was controlled by the remote user seeing the transmitted image.・ Image enhancementImage processing schemes were developed to enhance the quality of the images, which made use of multiple differently focused images and generates various special effect on images including all focus image.
