Automatic identifying method for vehicle number plate through colour separating treatment and reintegration result

Abstract

The present invention is color separation and integration method of distinguishing license plate number automatically. The color image of license plate is separated into three components of red, green and blue and constituted into grey scale matrix figures for automatic distinction and the separated detection results are then integrated. Of these three components, there is always one component, which is relatively suitable for obtaining better detection result. Different license plate color may correspond to different license plate number coding rules.

Description

technical field [0001] The present invention relates to a license plate automatic recognition method for the results of color separation processing and aggregation, in particular to a method for individually graying out the three components of R (red), G (green) and B (blue) in a color image of a vehicle. An automatic license plate recognition method that performs automatic license plate recognition on Bitmap, and then collects the individual license plate recognition results of the three components of R, G, and B. Background technique [0002] Press, most of the existing license plate recognition methods are to recognize the integrated gray-scale matrix image that is converted into an integrated gray-scale matrix image by merging the individual gray-scale matrix images of the three components of R, G, and B. In this way, the identification result may have errors. [0003] This shows that above-mentioned existing method still has many shortcomings, is not a good design, and...
