Problems solved by technology

[0030] The purpose of the present invention is to solve the troublesome problem of car pipe steel seal picture comparison, collect the steel seal 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 compare the two scanned pictures by image The size of each pixel is divided into several pixels, 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 scans cannot be 100% the same, each similar Finally, the user can judge the authenticity of the two seals according to the size of the similarity value, and realize the comparison of the completeness of the steel seal by the above method

Embodiment 1

[0032] The steel seal integrity comparison system of the vehicle management institute, which adopts the C / S development model, is mainly used in cities and counties in Jiangsu Province. The vehicle management institute needs to compare the steel stamp number in the vehicle qualification certificate in business applications such as vehicle annual inspection and transfer of ownership , In the past, there were many differences in the comparison method with the naked eye, which could not be compared accurately, and it was time-consuming and cumbersome. The pixel-to-point comparison technology solved this problem.

[0033] The process of this embodiment is:

[0034] Firstly, the customer scans the steel seal of the vehicle management office into the system, then scans the steel seal number on the motor vehicle certificate into the system, and places the two pictures in the left and right picture frames, and the system presses the two scanned pictures according to the size of the ima...

Abstract

The invention relates to actual application of a technology for comparing pixels in point-to-point to the public security traffic control industry. In a system with a C / S (Client / Server) architecture, the comparison of the authenticity of scanning pictures of two seals or steel seals by naked eyes is always trouble and the errors exist. According to the technology, the two scanning pictures are divided into a plurality of pixel points according to the sizes of the images and each pixel point is numbered by using an API (Application Program Interface) technology of WINDOWS, then the pixels at the same position are subjected to three primary-color comparison and the similarity can be calculated. Since the completely identity of the two scanning parts is impossible, various similarities are accumulated, the average value of the similarities is solved and finally the authenticity of the two seals can be judged by the user according to the similarity value.

Description

technical field [0001] The present invention relates to the practical application of pixel point-to-point comparison technology in the public security traffic control industry. In the system of C / S framework, it has always been very troublesome to compare the authenticity of the scanned pictures of two seals or steel seals by naked eyes, and There is an error. This technical method divides the two scanned pictures into several pixels according to the size of the image through the API technology of WINDOWS, and numbers each pixel, and then compares the three primary colors of the pixels at the same position, and calculates Similarity, because two scanned copies cannot be 100% identical, each similarity is accumulated and averaged, and finally the user can judge the authenticity of the two seals according to the similarity value. Background technique [0002] C / S and B / S modes are currently two mainstream system architecture modes. The characteristics, advantages and disadvant...
