System language switching method, readable storage medium, terminal device, and apparatus

A non-transitory computer readable storage medium which stores computer readable instructions, wherein when the computer readable instructions are executed by a processor, the following steps are implemented:

• obtaining a preset image for setting a system language of a target terminal;
• extracting text information in the preset image, wherein extracting the text information comprises:
• performing graying processing on the preset image to obtain a gray-scale image of the preset image;
• performing equalization processing on the gray-scale image, and mapping gray values of the gray-scale image according to a preset mapping rule, to obtain an equalized gray-scale image of the preset image, wherein each mapped gray value is proportional to a corresponding cumulative distribution probability;
• performing binarization processing on the equalized gray-scale image to obtain a binary image of the preset image;
• denoising the binary image to obtain a denoised image of the preset image;
• and
• extracting text information in the denoised image;
• determining a target language corresponding to the text information, which includes:
• selecting a language with a highest priority from a preset language library, as a current matching language;
• calculating a degree of matching between the text information and the current matching language, wherein calculating the degree of matching comprises:
• comparing characters in the text information with an identification template respectively, wherein if a character is found in the identification template, the character is successfully matched, and wherein if the character is not found in the identification template, the character matching fails;
• dividing a total number of successfully matched characters by a total number of the characters;
• and
• obtaining the degree of matching between the text information and the current matching language, wherein if the degree of matching between the text information and the current matching language is less than or equal to a preset threshold, a language with a highest priority that has not been matched as the new current matching language is selected from the language library, and then the step of calculating the degree of matching between the text information and the current matching language is executed;
• and
• determining the current matching language as the target language if the degree of matching between the text information and the current matching language is greater than the threshold;
• and
• switching the system language of the target terminal to the target language.

A system language switching terminal device, comprising a memory, a processor, and computer readable instructions stored in the memory and executable on the processor, wherein the processor implements the following steps when executing the computer readable instructions:

• obtaining a preset image for setting a system language of a target terminal;
• extracting text information in the preset image, wherein extracting the text information comprises:
• performing graying processing on the preset image to obtain a gray-scale image of the preset image;

• performing binarization processing on the equalized gray-scale image to obtain a binary image of the preset image;
• denoising the binary image to obtain a denoised image of the preset image;
• and

• and
• determining the current matching language as the target language if the degree of matching between the text information and the current matching language is greater than the threshold;
• and
• switching the system language of the target terminal to the target language.
