Embodiments of the present invention provide a method and system for vehicle logo recognition, wherein the method includes: obtaining the current frame of the vehicle logo image; judging whether the vehicle in the current frame of the vehicle logo image and the previous frame of the vehicle logo image are the same vehicle; if not , then use the car logo classifier to detect the current frame of the car logo image to obtain the current frame of the car logo area; if so, then judge whether the previous frame of the car logo image has an output car logo recognition result, if there is output, then end the operation, If there is no output, it is judged whether the previous frame of the vehicle logo area is successfully tracked, if successful, the current frame of the vehicle logo area is obtained according to the tracking result, if not successful, the current frame of the vehicle logo image is detected using the vehicle logo classifier, Get the current frame logo area; match the current frame logo area with the standard logo template for SURF feature points, if the number of matched SURF feature points is greater than the threshold, the match is considered successful, and the car logo recognition result is output, if the match is unsuccessful , then track the vehicle logo area in the current frame.
Description
technical field [0001] The invention relates to the field of image processing, in particular to a vehicle logo recognition method and system. Background technique [0002] At present, the license plate recognition equipment has been widely used at the entrance and exit of the parking lot to manage the vehicles entering and leaving the venue. The current license plate recognition system uses the mode of entering and taking cards, one car and one card for license plate recognition. However, because the license plate recognition rate of the license plate recognition equipment is generally only about 95%, it is impossible to guarantee that all the captured license plates can be fully recognized. Therefore, staff are generally deployed at the entrance and exit of the parking lot to assist in the license plate equipment. However, in recent years, with the increase of labor costs, unattended parking lots have begun to be promoted. License plate recognition is still the only standar...
