项目摘要

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.

本项目旨在通过无线网络实现远程控制的移动平台图像采集。研究中所做的工作如下。·搭建移动平台移动平台是由机动轮椅制成的。控制系统基于PC机，移动平台采用PC机指令控制。移动的方向和速度是可控的。·通过局域网和PHS通信系统对移动平台进行控制，使移动平台在基于TCP/IP协议的局域网或小灵通网络下远程控制。·视频压缩视频压缩方案是为移动平台上基于PC的视频通信而开发的，通过该方案，远程控制站点能够捕获移动平台周围的视图。视频压缩方案基于空间可变采样，对中心区域进行更详细的成像，而对外围区域进行更不详细的成像。·通过小灵通无线网络进行遥控移动平台图像采集实验。将移动平台上的摄像机通过小灵通无线网络传输的图像进行采集。移动平台由远程用户看到传输的图像进行控制。·图像增强图像处理方案是为了提高图像质量而开发的，它利用了多个不同聚焦的图像，并在图像上产生各种特殊效果，包括所有聚焦图像。
