[0035] The present invention will be further described below in conjunction with the accompanying drawings.
[0036] refer to figure 1 , a kind of number plate recognition method based on support vector machine, described recognition method comprises the steps:
[0037] 1) Obtain number plate image I 1 ;
[0038] 2) Carry out color preprocessing to the image, the specific steps are as follows:
[0039] 2.1) Convert the image I 1 Perform color space conversion to obtain image I in HSV color space 2 ;
[0040] 2.2) The image I 2 Perform histogram equalization to obtain image I 3 ;
[0041] 2.3) Convert the image I 3 According to the brightness threshold, the grayscale image I is obtained 4 ;
[0042] 3) For image I 4 Carry out Canny operator edge detection to get the edge image I 5 ;
[0043] 4) For edge image I 5 Carry out the rectangular frame of the digital area, the specific steps are as follows:
[0044] 4.1) By pairing the edge image I 5 Perform contour ex...
