Abstract: According to thefeatues of the low llimination intensity in the underground mine and the mine narrow and long roadiwaya single video camera and miners lamp video postioning algorthn was provided based on the wireless multimedia senson network faced to the strip struture roadwvay in the underground mine. nthemine roadiway with the l l.uminato intensity the miners lamp would be the feature indentified object of the underground persome. Nith derection of the miner's lamp.the underground personel could be indentfied.The video cameras set along the stip structure roadway inthe longitudinal drection could individually detect the miner's lamp and theground refecionlocato of the lamp in the roadiway could be caculated.A D space straight line formed with the video camera and the lamp ground refection pit inthe roadway was established. with the caculaton on the 3D space traightline fomed with the camera and the lamp refection point and the plane cvossing point fromn lamp distance to the roadway ground height,the locaion coordinates of the underground perso1el could be obtained and theposiining fthe underground person1el could be realized in thestrip structure roadwa withthe low llimination intensity The experiment resuts in the acual oadvay showved that the a singlevideo camera and miner's amp video posttoning algorithm would have an average error of 0.37 m for the underground personnel postioning.
