Tesseract-OCR is an OCR engine developed by the HP lab from 1985 to 1995. Later, it was developed by Google and open-source. It supports multiple platforms and supports up to 40 languages, including Chinese, supports training. Tesseract-OCR is a command line.ProgramBut it also provides wrapper in multiple languages, such as. net.,

Optical character recognition (ocr,optical Character recognition) refers to the process of scanning text data, and then analyzing and processing the image files to obtain the text and layout information. OCR technology is very professional, generally many printing, printing industry practitioners use, can quickly convert paper data into electronic data. About Chinese OC
What is OCR? Suppose you want to digitize a magazine article or print a contract. You may need to take the time to re-enter and correct the error. Alternatively, you can use scanners (or digital cameras) and optical character recognition software to convert all materials into digital formats in just a few minutes.

input VIN code, because 17-bit code is composed of digital and English mixed arrangement, on the phone manually input 17-bit VIN code, slow, error prone, often need multiple input, multiple verification, the user experience is very poor. Using the VIN Scan Tool, you will find that VIN code entry is very fast and can be read into VIN code in 1 seconds, and this revolutionary technology has changed the experience of VIN code recognition.The "Traffic Police assistant" uses
