Abstract:This paper studies the use of image recognition technology to assist nuclear power enterprises in the application of document intelligence. The article expounds the business background, main process, implementation principle and typical application scenario solutions for the application of image recognition technology, through the automatic detection of the sharpness of scanned documents based on image recognition technology and the automation of documents based on optical image recognition technology. Split and compare these two application scenarios, expound the problems faced, the principle of the solution, the specific program function design and the final application effect. According to the evaluation of the application effect, it is proved that the image recognition technology can play an important role in the intelligent application of documents. Through the research and practice of this subject, a useful exploration is made for the intelligent use of documents based on image recognition technology.
