| Research Abstract |
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.
