The invention discloses a vehicle identification method based on window segmentation and fuzzy characteristics. The vehicle identification method comprises extracting the edge of a front face image of a vehicle; then conducting quadrilateral fitting according to the edge so as to quickly segment a front windshield contour of the vehicle; next, extracting HSV image histogram characteristics in the range of windshield; and finally retrieving the vehicle through the contrast of region Fuzzy difference measurement of HSV histograms. According to the invention, the vehicle identification method gets rid of the unreliability of retrieval only relying on license plates, and the vehicle image retrieval results are improved.
