The invention discloses an archive real-time positioning method based on fisheye lens image recognition. The archive real-time positioning method comprises the following steps: 1, fisheye lens collection; 2, image preprocessing: performing distortion correction on the acquired image of a digital tag; 3, image X direction segmentation and archive box X direction positioning; 4, image Y direction segmentation: enabling each digit in the digital label on the Y axis to have a digital image; 5, digital recognition; 6, establishing a real-time association library of the digital tags and the X-direction position numbers: performing one-to-one correspondence on the X-direction position numbers of the file boxes identified in the step 3 and the clear digital codes of the digital tags obtained in the step 5 according to X-direction coordinates, and establishing the real-time association library of the digital tags and the X-direction position numbers; and 7, searching for archives. The archive real-time positioning method uses the fisheye camera, realizes image identification of the digital tag through a rectangular contour detection mode, and performs positioning by means of the position ofthe digital column in the image.
Description
technical field [0001] The invention relates to a file management method, in particular to a file real-time positioning method based on fisheye lens image recognition. Background technique [0002] At present, modern archives store files in the form of carousels or compact shelves. There are three main methods of inventory storage: [0003] 1. Use the manipulator to hold the barcode gun, and scan the barcodes of the file boxes arranged on the file cabinet to obtain the file number and location information. [0004] 2. Change the barcode gun to a radio frequency card reader, and move and read the electronic label attached to the file box on the filing cabinet. [0005] 3. Arrange the radio frequency card readers in a row, each card reader faces a file box, and obtain the electronic label number attached to the file box from each radio frequency card reader, and at the same time actually obtain the location information of the file. [0006] The first two methods are cheap, b...
