Android phone license plate recognition OCR
Introduction and development of OCR technology for Android mobile phone license plate recognition
The concept of OCR was first proposed by German scientist tauscheck in 1929 and applied for a patent. Later, Handel, an American scientist, also put forward the idea of using technology to recognize characters. The earliest commercial application of OCR in China was developed by scientist Professor Wang Qingren at Nankai University and put into commercial use in the American market. OCR recognition process mainly includes: image input, image pre-processing and pre recognition; Binarization; Noise removal; Tilt correction; Layout analysis; Character cutting; Character recognition; Layout restoration; Post processing and proofreading.

Android mobile phone license plate recognition OCR application background
With the substantial increase of motor vehicles, it not only drives the development of the national economy, but also brings many troubles to China's road traffic. Motor vehicle violations are one of the main reasons for traffic accidents and affecting the normal traffic order; Parking is difficult, and parking lot management needs a more intelligent and efficient management mode. As the only ID card of the vehicle, the particularity and importance of license plate number has become an indispensable part of intelligent transportation system. How to quickly input these license plate numbers? Xiaobian will ask you a move today.
