Method for comparing vehicle engine number by pixel point comparison technique

Abstract

The invention relates to the actual application of a pixel point comparison technique in the industry of public security traffic management. In the system of a C / S framework. The authenticity comparison of two scanning pictures of the vehicle engine number by eyes is difficult, and error exists. According to the technique, the two scanning pictures are divided into a plurality of pixel points according to the sizes of the pictures via an API technique of WINDOWS, and each pixel point is numbered; the pixels at the same position are compared in three-primary colors, and the similarity is calculated; because two scanning pictures are not equal by 100%, all similarities are accumulated, and the average value is determined; finally, the consistence of two vehicle engine numbers is judged according to the size of the similarity value by users.

Description

Technical field [0001] The present invention relates to the practical application of the pixel comparison technology in the public security traffic management industry. In the C / S framework system, it is always very troublesome to compare the authenticity of two vehicle engine numbers with naked eyes. Error, this technical method uses the WINDOWS API technology to divide the two scanned pictures into several pixels according to the size of the image, and number each pixel, and then compare the three primary colors of the pixels at the same position and calculate the similarity Because the two scans cannot be 100% the same, each similarity is accumulated and the average value is calculated. Finally, the user can judge the consistency of the engine numbers of the two vehicles based on the similarity value. Background technique [0002] C / S and B / S modes are currently two mainstream system architecture modes. The characteristics, advantages and disadvantages of the two modes are as ...

Problems solved by technology

[0030] The purpose of the present invention is to solve the problem of troublesome comparison of vehicle engine number pictures for vehicle management, collect the vehicle engine number pictures through the scanner, place the two pictures in the left and right picture frames, and the system uses the API technology of WINDOWS to convert the two pictures A scanned picture is divided into several pixels according to the size of the image, and each pixel is numbered, and then the pixels at the same position are compared with the three primary colors, and the similarity is calculated, because two scanned copies cannot be 100% identical , accumulate each similarity and calculate the average value, and finally the user can judge the consistency of the two vehicle engine numbers according to the size of the similarity value, and realize the method of vehicle engine number integrity comparison through the above method
