What does ocr mean in Chinese?

Ocr means optical character recognition in Chinese.

OCR (Optical Character Recognition) refers to the process that electronic devices (such as scanners or digital cameras) check the characters printed on paper, determine their shapes by detecting light and dark patterns, and then translate the shapes into computer characters through character recognition.

OCR is a technology that converts printed characters into black-and-white dot-matrix image files by optical means, and converts characters in images into text formats by recognition software for further editing and processing by word processing software.

Extended data:

The purpose of an OCR recognition system is very simple, that is, to transform the image, so that the graphics in the image can be kept, and the data in the table and the characters in the image can be turned into computer characters, which can reduce the storage of image data, reuse and analyze the recognized characters, and of course save the manpower and time of keyboard input.

From the image to the result output, we should go through image input, image preprocessing, text feature extraction, comparison and recognition, and finally correct the typo by manual correction and output the result.
