1) original license plate image is obtained
Taken by terminal device.
2) Image semantic classification
Cloud computing platform to dynamic acquisition to license plate image carry out filtering, border enhancing etc. process to overcome image disruption.
3) License Plate
Cloud computing platform, by the projected area of edge calculation image, is found peak valley point, is roughly determined car plate position, then calculates the ratio of width to height in this connection, rejects not in the connected domain of domain value range, and what finally obtain is just license plate area.
4) Character segmentation
The character locating dividing method that cloud computing platform utilizes projection to detect obtains single character.Usually to the character split be processed, normalized to standard form.
5) character recognition
Method and the character in database of cloud data base manipulation template matches carry out mating thus confirming character, obtain last license plate, comprise English alphabet and numeral.Template matches needs first to treat identification character and carries out binaryzation and the size its size being scaled template in character database, then mates with all templates, finally selects optimum matching as a result.
The similarity function adopted during template matches is as follows:
Wherein, f (ij) is the gray-scale value of pixel (ij) in characters on license plate image to be identified, and value is here 0 or 1,
T (ij) is the gray-scale value of pixel (ij) in template character picture, value be here 0 or 1, M and N be the horizontal and vertical number of pixels comprised of template character pattern.That is, the eigenwert of characters on license plate image is the gray-scale value of pixel in characters on license plate image.The eigenwert of template character is the gray-scale value of the pixel in template character picture.
The step of template matches is as follows:
A, take out template character successively, by template character according to four direction up and down, slide in the scope of five pixels around, calculate similarity S value respectively at every turn, get maximal value S wherein as the similarity between characters on license plate and template character.
B, from the similarity of characters on license plate to be identified and template character, find out template character corresponding to maximum similarity value successively, judge whether maximum similarity value is greater than the threshold value of this character; If so, the matching result of characters on license plate so to be identified is exactly this template character; If not, then recognition failures.
After c, character match, demonstrate mated character.
