[0032] figure 1 It is a schematic flowchart of a document scanning image correction method provided in the first embodiment of the present application, as shown in figure 1 As shown, the method includes:

[0033] S101. Acquire the scanned document image and projection values ​​of light beams in different angle directions of the document image, and determine the skew angle of the document image according to the projection values ​​of light beams in different angle directions of the document image.

[0034] Specifically, the processing terminal receives the data information of the document image scanned by the scanning instrument, and the preset projection algorithm can be used to project the document image from different angles by using a series of parallel beams (hereinafter referred to as beams) through the pixel traversal method. Calculate the projection values ​​of the light beams in different angle directions of the document image, so that the processing terminal will obt...

Abstract

The invention provides a document scanning image correction method and device, and relates to the technical field of archive management. The document scanning image correction method comprises the following steps: correcting a document scanning image; obtaining scanned document images and projection values of light beams of the document images in different angle directions; the deflection angle ofthe document image is determined according to the projection values of the light beams in different angle directions of the document image; judging whether the deflection angle of the document imageis greater than a preset threshold value or not, if yes, determining the document image as the deflection image, and obtaining a corrected image of the deflection image based on the picture generationnetwork model and the training weight value of the picture generation network model, so that the labor cost is reduced, and meanwhile, the document scanning efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of file management, in particular to a method and device for correcting scanned images of documents. Background technique [0002] Archives information is generally stored in paper documents in the archives. It is time-consuming to search and retrieve. The space for storing archives is large and inconvenient to maintain. Backing up archives requires a lot of manpower and material resources, and manual processing is even more unreliable. With the digitization of archives information With the development of the development, the paper documents are scanned and entered into the computer database, and the computer stores the archive information, which makes the retrieval of archive information faster and more convenient, and brings great convenience to people. [0003] However, in the process of scanning archives information, some human or equipment factors may inevitably cause a certain degree of skew to the sca...
