Problems solved by technology

[0007] To sum up, the number displayed on the display segment of the nixie tube is determined through the existing technology, that is, the code table of the threading recognition method. To determine the number in an average image requires 5.3 times of recognition and judgment, and the recognition efficiency is extremely low.

Abstract

This application provides a method and equipment for digital recognition, which is used to determine the mapping relationship between horizontal characteristic parameters and numbers by searching the preset horizontal mapping table, optimize the image recognition process, reduce the number of process judgments, and improve the digital recognition. The speed improves the recognition efficiency. The method includes: analyzing an image containing a single number, determining the horizontal characteristic parameter of the number in the image; judging whether the preset horizontal mapping table includes the mapping relationship between the horizontal characteristic parameter and the number; if so, then Determine that the number corresponding to the horizontal feature parameter is a number in the image; otherwise, determine the number in the image according to the horizontal feature parameter and the vertical feature parameter of the number in the image.

Description

technical field [0001] The present application relates to the technical field of information security, in particular to a digital identification method and equipment. Background technique [0002] Nowadays, the recognition of the numbers displayed on the electronic screen is mainly realized through the threading method. Among them, the numbers displayed on the electronic screen can be found in figure 1 . The identification principle of the threading method is based on the characteristics of the seven-segment digital tube. The numbers displayed on the electronic screen are mainly composed of seven digital tube display segments; wherein, the digital tube display segments include a first digital tube display segment 101, a second digital tube display segment 102, a third digital tube display segment 103, The fourth digital tube display segment 104 , the fifth digital tube display segment 105 , the sixth digital tube display segment 106 and the seventh digital tube display seg...
