The invention provides a real estate certificate identification method, device and apparatus. The method comprises the steps of obtaining a to-be-identified real estate certificate picture; performingtable extraction on the to-be-identified real estate certificate picture to obtain a real estate certificate table picture corresponding to the to-be-identified real estate certificate picture; obtaining a target real estate certificate form template matching the real estate certificate form picture from a pre-constructed real estate certificate form template library; according to preset coordinates of cells of interest of the target real estate certificate form template, performing cell interception on the real estate certificate form picture to obtain a plurality of intercepted cells; and identifying the content of each interception cell to obtain real estate certificate information. By adopting the technical scheme of the invention, the data of the real estate certificate can be accurately identified under the condition of a small amount of real estate certificate data.
Description
technical field [0001] The present invention relates to the technical field of image recognition, in particular to a real estate certificate recognition method, device and equipment. Background technique [0002] Premises Permit refers to the certificate that the buyer obtains the legal ownership of the house through transactions, and can exercise the right to possess, use, benefit from and dispose of the purchased house in accordance with the law.
