Abstract

The invention is applicable to the technical field of image scanning and provides an image scanning method, system and device, and a computer readable storage medium, wherein the method comprises thefollowing steps: if an image scanning command issued by a computer is received, judging whether correction reference data are stored in the memory of an FPGA or not; if the correction reference data are stored in the memory of the FPGA, setting a sampling data output mode of the FPGA as a correction data output mode; and controlling the FPGA to read image data from the memory, correcting the imagedata by using the correction reference data in the memory, and reporting the corrected image data to the computer. According to the image scanning method, system and device and the computer readablestorage medium, the image scanning time can be shortened, the real-time performance of the system can be improved, and the output of high-quality image data can be ensured.

Description

technical field [0001] The invention belongs to the technical field of image scanning, and in particular relates to an image scanning method, system, device and computer-readable storage medium. Background technique [0002] In the existing bill image scanning device, the contact image sensor (Contact Image Sensor, CIS) is composed of multiple segments spliced ​​together. There are large inconsistencies, which seriously affect the quality of image collection, so the collected images must be corrected. At present, in order to improve the image quality collected by CIS in the bill image scanning device, the method adopted is to correct the image collected by CIS on the PC side. This image correction method takes a long time and seriously affects the real-time performance of the system. Contents of the invention [0003] In view of this, the present invention provides an image scanning method, system, device and computer-readable storage medium to solve the problem that the ...
