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.

传感器不再是集中控制的遥测传感器，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，在环境中组成一个测量网络。利用普适计算的三维位置测量功能，本项目专门研究了姿态位置测量技术。无线电通信较弱，但图像处理和三维测量技术的无线仅由光空间通信建立。对于分散的、以图像管理主机为中心的新的组成方案，同时进行了新的研究，即GHz频段的模拟无线传输摄像机，本项目成果包括：1）自组织无线网络中位置和姿态信息的同时获取算法，2）设计光空间通信节点之间的交换协议; 3）设计同路模拟无线传输摄像机与图像管理主机的图像传输控制的控制协议。针对1）超小型图像识别板和微型CCD摄像机组成的组合传感器节点，实现了位置姿态的同时测量功能。实现了传感器节点按计划的姿态测量。2）利用超小型图像识别板的图像管理功能进行了基于光空间通信的自组网的分组设计和协议设计，并进行了测量验证实验。通过使用硬币图案270 K像素CMOS摄像机接收与服务器的信号约3），并且使用弱无线电来进行摄像机和LED的电源控制。
