METHOD AND APPARATUS FOR EXTRACTING STRUCTURED DATA FROM IMAGE, AND DEVICE AND STORAGE MEDIUM

Document Type and Number:

WIPO Patent Application WO/2021/151270

Kind Code:

A1

Abstract:

A method and an apparatus for extracting structured data from an image, and a device and a storage medium, relating to the field of artificial intelligence. The method comprises inputting an image for structured data extraction into a position detection model to obtain coordinates of each region for recognition in the image, slicing the regions for recognition and then performing transformation processing, inputting the regions for recognition from before transformation and after transformation into a recognition model to obtain initial recognition results, filtering target recognition results for each region for recognition from the initial recognition results, selecting classification results on the basis of the similarity between characters of each target recognition result and characters of each classification in a lexicon, and generating a structured data file on the basis of each classification result and the target recognition results. Structured data can thus be accurately extracted from image recognition results. In addition, the invention further relates to image recognition technology and blockchain technology within artificial intelligence, and can be applied in such fields as smart government and smart education, thereby promoting the construction of smart cities.
