Abstract

The invention relates to a character recognition system and method. One embodiment of the system comprises a light source, a digital micromirror array, a bucket detector and a computing device. The digital micromirror array converts light emitted by the light source into a dynamic speckle signal, and projects the dynamic speckle signal to the surface of a to-be-recognized target; the bucket detector receives a light intensity signal reflected by the to-be-recognized target; the calculation device performs second-order correlation calculation on the dynamic speckle signal and the light intensity signal to obtain a ghost imaging image of the to-be-recognized target; and inputting the ghost imaging image into a pre-trained character recognition model to obtain characters in a to-be-recognizedtarget. According to the embodiment, accurate recognition of the characters can be achieved with low cost.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a character recognition system and method. Background technique [0002] Image information is the most direct and effective information currently available. With the rapid development of information technology, optical imaging has been widely valued all over the world, and it occupies an indispensable position in the future development of science and technology. For example, in artificial intelligence, electronic payment, industrial automation, military industry and other fields, optics is inseparable. imaging technology. How to quickly obtain more effective target image information has become an important research topic for scholars all over the world. At present, high-speed camera technology is developing rapidly. Femtosecond-level cameras can capture images of 20 billion frames per second, but the optical path is complex and expensive. [0003] The current i...
