Image forming method, device, electronic device and readable storage medium

Abstract

The present invention provides an image forming method, device, electronic equipment and readable storage medium, by acquiring a scanned image containing a document image, and determining a reference edge among the edges of the scanned image according to preset first document edge features; Segmenting the scanned image into a plurality of segmented images with a segmenting line perpendicular to the reference edge, wherein each of the segmented images contains a partial image of the document image; The distortion information of the partial image, wherein the distortion information indicates the offset degree of each pixel of the partial image relative to the edge of its corresponding segment image; according to the distortion corresponding to each segment image information, respectively performing distortion correction on the partial images in each of the segmented images to obtain a corrected scanned image, which improves the accuracy of the acquired document image distortion information, thereby improving the accuracy and accuracy of the scanned image correction. reliability.

Description

technical field [0001] The present invention relates to image processing technology, in particular to an image forming method, device, electronic equipment and readable storage medium. Background technique [0002] Image-text copying usually places the document to be scanned or copied on the scanning table, then starts the image forming device, and uses an optical scanning device to scan the document image of the document to be scanned or transfer the document image to paper for output. When the document to be scanned is a book or bound material with a multi-page document structure, the document images scanned each time are two-page documents with adjacent page numbers. Since the book or bound material has a certain thickness, a spine is formed at the binding position, and the content of the document at different distances from the spine on the document image is different from the scanning table, resulting in the distortion of the obtained document image. [0003] In the ex...

Problems solved by technology

[0004] During the implementation of the image forming method, the inventor found that when scanning and copying books, problems such as document page folding, document image distortion, and serious shadow problems in the area where the spine is located often occur, resulting in inaccurate determination of the position of the spine, resulting in the final output. Corrected image still suffers from distortion

Distortion correction is not reliable with existing image formation methods
