代替遥测传感器所具有的集中控制功能，而是一个传感器本身具有近距离无线电通信功能和数据路由功能，并有一个自组织的传感器网络，构成一个环境中的测量网络。本课题利用泛在计算的三维位置测量功能，专门研究了姿态位置测量技术。微弱的无线电通信较少，但仅通过光空间通信建立了无线图像处理和三维测量技术。同时，针对分散的、中心有图像管理主机的新型组成方案，进行了新的研究，即GHz频段的模拟无线传输摄像机。本课题成果包括：1)自组织无线网络中位置与姿态信息的同步采集算法；2)设计光空间通信节点间的交换协议；3)设计同信道模拟无线传输摄像机与图像管理主机的图像传输控制协议。1)组合传感器节点采用超小型图像识别板和微型CCD摄像机，实现位置姿态的同步测量功能。可以实现传感器节点的预定姿态测量。利用超微型图像识别板的图像管理功能，对基于光空间通信的自组网进行了分组设计(1)和协议设计(2)，并进行了实测验证实验。采用投币式270K像素CMOS摄像头接收服务器约3)的信号，并采用弱无线电对摄像头和LED进行供电控制。

Instead of telemetry sensors which had central-controlled, but a sensor itself has near-distance radio communication function and a data routing function, and there is an ad hoc sensor network, composes a measurement network in the environment. The 3D position measurement function of the ubiquitous computing use specially researched the technique of the posture position measurement in this project. It was weak radio communication less much, but image processing and the 3D measurement technology of wireless only by the optical space communication were established. As for the new composition argument as well which dispersed and which had a image management host in the center, new research was carried out at the same time, which is an analog wireless transmission camera of the GHz band.This project results include 1) simultaneous acquisition algorithm of the position in the ad hoc wireless network and the posture information, 2) design an exchange protocol between the nodes of the optical space communication, 3) design of the control protocol of the image transmission control of the same channel analog wireless transmission camera and the image management host. As for 1) combination sensor node was built with a super-miniature image recognition board and the miniature CCD camera to stick to the simultaneous measurement function of the position posture. The posture measurement of the sensor node as planned could be realized. The packet design of the ad hoc network based on the optical space communication by the image management function of the super-miniature image recognition board of 1) and protocol design were held about 2), and a measurement actual proof experiment was done. A signal with the server was received about 3) by using the coin pattern 270K pixels CMOS camera, and weak radio to do the power supply control of the camera and LED was used.
