Embodiment 1

[0096] Such as figure 1 As shown, the method for cracking the Chinese character verification code of the present embodiment comprises the following steps:

[0097] S100. Obtain the target position of each Chinese character in the target image;

[0098] S101. Obtain the outline of the target Chinese character in the target position;

[0099] S102. Obtain the corresponding target Chinese character according to the outline of each target Chinese character;

[0100] S103. Obtain the outline of the reference Chinese character in the reference image;

[0101] S104. Obtain the corresponding reference Chinese character and the execution sequence of each reference Chinese character in the set direction according to the outline of each reference Chinese character;

[0102] S105. Obtain a clicking result corresponding to the target Chinese character in the target image according to the execution order and the reference Chinese character.

[0103] The method for cracking the Chinese c...

Embodiment 2

[0105] Such as figure 2 As shown, the method for cracking the Chinese character verification code in this embodiment is a further limitation to Embodiment 1, specifically:

[0106] Step S100 includes:

[0107] S1000. Obtain the target position of each Chinese character in the target image by using the YOLO framework;

[0108] Step S101 includes:

[0109] S1010, using a grayscale processing method to remove the image background of the Chinese characters in the target position to obtain the first image;

[0110] S1011. Perform noise removal processing on the first image to obtain a second image;

[0111] S1012. Perform Unicom processing on the Chinese characters at the target position in the second image to obtain the outline of the target Chinese character;

[0112] Step S102 includes:

[0113] S1020. Taking Chinese character images with different rotation angles of the same training Chinese character as input, training Chinese characters as output, and establishing a tar...

Embodiment 3

[0151] Such as Figure 4 As shown, the system of deciphering the Chinese character verification code of the present embodiment includes the following modules:

[0152] The target position acquisition module 1 is used to obtain the target position of each Chinese character in the target image;

[0153] The first outline acquisition module 2 is used to acquire the outline of the target Chinese character in the target position;

[0154] The target Chinese character acquisition module 3 is used to obtain the corresponding target Chinese character according to the outline of each target Chinese character;

[0155] The second contour obtaining module 4 is used to obtain the reference Chinese character contour in the reference image;

[0156] Reference Chinese character obtaining module 5, for obtaining corresponding reference Chinese character according to each described reference Chinese character profile;

[0157] Execution order acquisition module 6, used to obtain the executi...

Abstract

The invention discloses a method and a system for cracking a Chinese character verification code, electronic equipment and a storage medium. The method comprises the following steps: acquiring a target position of each Chinese character in a target image; obtaining a target Chinese character contour in the target position; obtaining a corresponding target Chinese character according to each targetChinese character contour; obtaining a reference Chinese character contour in the reference image; obtaining a corresponding reference Chinese character and an execution sequence of each reference Chinese character in a set direction according to each reference Chinese character contour; and obtaining a click result corresponding to the target Chinese character in the target image according to the execution sequence and the reference Chinese character. According to the method for cracking the Chinese character verification code, the clicking position and the clicking sequence of the rotatingChinese character can be rapidly and effectively determined, and then the Chinese character verification code is cracked through simulated clicking.

Description

technical field [0001] The invention belongs to the technical field of verification code recognition, and in particular relates to a method, system, electronic equipment and storage medium for cracking Chinese character verification codes. Background technique [0002] Graphical verification code (CAPTCHA) is widely used in the Internet, whether it is account login, information retrieval, data download, or even frequent operations of certain functions by users after login. In order to ensure operational security, websites or client programs Generally, the user is required to enter a verification code to proceed to the next step. There are various forms of graphic verification codes. At present, the common ones are Chinese character recognition, character recognition (Chinese and English), slider puzzle, word selection, scene recognition, etc. Among them, Chinese character verification code is the most widely used. One of the verification code forms. At present, generally o...
