Abstract

A document scanning and processing equipment and processing method, which has an embedded system. The embedded system includes a CPU; it is connected to the CPU through a memory interface, and has a DDR or NandFlash memory solidifying an operating system and a computer vision special function library; and the CPU is connected through The camera connected to the I / O interface, SD card / CF card storage interface, USB interface, Ethernet or WIFI transmission interface, document scanning processing includes: obtaining the original color document image; grayscale the original color document image; grayscale document The image is matched and enhanced to obtain an enhanced grayscale document image; the global binarization of the enhanced grayscale document image is performed to obtain a binarized document edge image; the maximum contour and boundary points of the effective area are determined; the original image is subjected to affine restoration transformation; Perform histogram equalization on the image obtained by the affine restoration transformation, adjust the contrast and brightness, and obtain the adjusted color document image. The adjusted color document image is transmitted via USB, Ethernet or wifi, or saved to an SD card or CF card. middle.

Description

technical field [0001] The present invention relates to a processing device and a processing method applied to document scanning, and in particular to a document scanning processing device which is improved for defects such as affine distortion, skew, low brightness, and low contrast in images during document scanning and processing methods. Background technique [0002] With the increasing electronicization of daily life and office environment, people will be faced with scanning a large number of paper documents and storing them in the computer, and document materials are scanned and stored in the computer, which makes the storage, transmission and management of documents more convenient. Quick and standard. Electronic document storage and backup have been gradually popularized in intelligence and information departments, financial departments, file management departments and other industrial and commercial enterprises. In the prior art, since the placement of the documen...
