Problems solved by technology

[0002] Printers are office equipment often used in daily life, but the existing printers can only fully present the contents of the electronic version. For the printed contents, once an error occurs, they cannot be changed and need to be reprinted, which causes resources to be exhausted. waste and unnecessary pollution

Embodiment 1

[0018] Embodiment 1: as Figure 1-3 As shown, a printing error correction method based on image processing technology, the method steps are as follows:

[0019] S1. Put the paper file to be corrected after printing the original electronic file on the computer into the paper feeding mechanism 2 of the printer;

[0020] S2, the image of the paper file to be corrected is transmitted to the computer through the high-definition camera 4 through an electrical connection, and the length and width of the image of the paper file to be corrected to be identified are compared with the original electronic file: if there is a deviation, you need to Adjust the image of the paper document to be corrected, and re-identify the paper document to be corrected until the image length and width of the identified paper document to be corrected are the same as the original electronic document;

[0021] S3. The computer uses CNN to perform feature analysis and extraction of the image of the paper doc...

Abstract

The invention discloses a printing error correction method based on an image processing technology. The printing error correction method comprises the steps of transmitting an acquired image of a to-be-corrected paper file to a computer through a high-definition camera in an electric connection mode; enabling the computer to perform feature analysis and extraction on a paper file image to be corrected by using the CNN, and recording boundary coordinate value and background pixel value of each graph in the data storage module in pairs; manually marking the area of the error content in the to-be-corrected paper file image on the computer as a mark area A; comparing the coordinate value of the mark area A with the coordinate value of each graph boundary, and calling a matched background pixel value to fill the mark area A to serve as a mark area B; correcting the original electronic file on the computer, and conducting pixel value extraction on the corrected area of the corrected electronic file; and calling the corrected pixel value to fill the mark area B. The printed wrong content can be corrected under the condition that printing paper is not replaced.

Description

technical field [0001] The invention relates to a printing error correction method based on image processing technology, which belongs to the field of image processing. Background technique [0002] Printers are frequently used office equipment in daily life, but the existing printers can only fully present the content of the electronic version. For the printed content, once an error occurs, it cannot be changed and needs to be reprinted, which results in resource consumption. waste and unnecessary pollution. Contents of the invention [0003] The invention provides a printing error correction method based on image processing technology, which is used for correcting the wrongly printed content without changing the printing paper. [0004] The technical solution of the present invention is: a printing error correction method based on image processing technology, the steps of the method are as follows: [0005] S1. Put the paper file to be corrected after printing the orig...
