Abstract

The invention discloses a method for positioning and recognizing a vehicle logo. The method comprises the following steps of: collecting the vehicle head image of a vehicle by a high-definition camera; positioning the vehicle and positioning and recognizing a vehicle registration plate according to the vehicle head image, and generating the estimated position region of the vehicle logo according to the prior information of the vehicle logo and the vehicle registration plate; in the estimated position region of the vehicle logo, filtering the background region disturbance of the vehicle logo according to extracted texture information, carrying out binaryzation on the texture grey-scale map of the vehicle logo, on which the background region disturbance of the vehicle logo is filtered, accurately positioning the vehicle logo on the generated binary image through a method of finding connected domains in the estimated position region of the vehicle logo and generating the accurate position information of the vehicle logo; according to the accurate position information of the vehicle logo, extracting the accurate grey-scale map of the vehicle logo, carrying out binaryzation on the accurate grey-scale map of the vehicle logo, and generating a binary map corresponding to the vehicle logo; and matching the binary map corresponding to the vehicle logo with a prestored vehicle logo format, carrying out weighing calculation according to the position information, and viewing the vehicle logo type corresponding to the highest score obtained by calculation as the recognizing result of the vehicle logo.

Description

technical field [0001] The invention relates to the field of traffic vehicle positioning and recognition, in particular to a vehicle logo positioning and recognition method and system. Background technique [0002] The car logo is the iconic image of the vehicle. It not only contains the model information, but also contains the manufacturer's information. More importantly, it is difficult to replace. If the vehicle logo information is combined with the license plate information, the reliability of vehicle identification will be greatly improved. In some criminal activities, although the license plate is easy to change, the car logo is unique. The car logo recognition technology can be widely used in traffic accident handling, automatic monitoring of illegal vehicles, automatic toll collection, automatic detection of vehicles in airports, ports, parking lots, communities, etc. Therefore, vehicle logo recognition has important theoretical significance and application value fo...
