In　this　paper,　we　proposed　a　pedestrian　information　analysis　system.　It　is　consisted　of　the　pedestrian　detection　module　and　the　pedestrian　tracking　module.　Compared　with　various　pedestrian　detection　methods,　the　Deformable　Part　Model　(DPM)　algorithm　is　used　to　detect　the　pedestrians　in　the　picture.　Meanwhile,　this　paper　proposes　a　pedestrian　tracking　method.　This　method　uses　the　pedestrian　detection　result　to　calculate　the　pedestrian＇s　centroid　and　uses　the　video　time　domain　information　to　track　the　centroid.　It　can　help　us　to　obtain　the　pedestrian　information　that　includes　the　pedestrian　moving　distance　and　direction.　We　set　the　count　line　to　count　the　pedestrian＇s　number　and　direction　in　this　system.　The　experiment　results　show　that　the　system　we　proposed　can　analyse　pedestrians　more　accurately.　©　Published　under　licence　by　IOP　Publishing　Ltd.
