Research, Agv Visual Navigation Based On Embedded Linux

AGV(Automated Guided Vehicle) is a kind of auto-mobiled robot on the ground,it could reach the destination by following the trace that we signed in some complex landform atmosphere with no difficulties, The reason we chose to use an AGV system is to avoiding harmful injuries in some kind of dangerous situation, to free labor form monoton works, by now, AGVs are widely toke part in manufacturing, medicine, spaceflight and military.and to implement the function of these AGVs needs many subject's background,et.sensor technology,data fusion, Image processing and contrail plan,modern control arithmetic. This thesis we take a look at an AGV system design by using the most popular ARM9 processor and embedded Linux operation,researched an auto vision-guided method about embedded Linux AGV system ,and implement the video-4-linux image sampling into Linux-AGV vision guided system.then, We analysis the Sobel Method ,Hough Method transformation,and Binary Digitalisation Method&Hough Metohd transformation,to analysis the route imformation from the image we got.and also we analysis 3 kind of methods to enhance the speed and precision of the system, also analysis the real-time efficiency of this vision-guided system on the other hand .In the end ,we desigd and realized an method about vision-guided based on embedded Linux AGV system .and at the end of this thesis ,We concluded the advantages using embedded system conception into the system design. The main work of this thesis included: form the cross-chain environment,transplant the embedded linux operation,compile the kernel,load the diryer software,design of the image sampling and processing,compare all those methods together,analysis the imformations about the route,and make the filysystem,and so on ,for the further researchers in this embedded Linux vision-guided work,this thesis could be helpful and instructive.
