A Research On ARM Based Vision System For Autonomous Wheel Robot

Since computer invented, people have been tring to to embed into robot system and been trying to make it behave automonmously. From science fiction to real robot roaming on Mars. Nowadays, mobile robots have been able to run autonomously in underwater, in air and outer space. Advances in mechanical design capabilities, sensing technologies such as vision, computing capabiility and image process, and intelligent algorithms for planning and control have led to the possibility of realizing autonomous mobile robot of pratical sense.This article described the designed and implementation of a monocular vision system for autonomous a vision navigaton autonomous wheel robot based on embeded system under un-controlled environment. Firstly, the article introduced the architecture of the system, harware designed. And then dicussed key techniques that used in software designed, such as memory mapping and double buffer sampling. At last we discussed the methodology, techniques that used in the visual system. Algorithm fesults are also presented in proper sections.The article try to focus on the ideas that: informations are distributed un-evenly in a scence, area that have more information suggesting that it may have "something" , possibly a obstacle. Also, the idea of information intensity is a new approach to described a scene.
