The system uses the CCD sensor as its route recognition device to sample the analog video sig nal directly from the CCD. And the current track information is draw n through image recognition. Compared w ith the normal route recognition scheme by means of the photoelectric cell sensor, using the CCD sensor can obtain more path information, w hich makes the smart car run smoothly at much rapid speed along the blackguide line given arbitrarily . T he experimental result show s that this meth od is simple and efficient w ith good forw ardlooking perspective, w hich can meet the demands of smart car path recognition.
