Abstract
The invention discloses a printing control platform of a printer, which comprises a script generation module, a script generation module and a printing module, wherein the script generation module is used for starting image printing, reading image preview identification information of printed paper and generating a printed image script; the sending module is used for sending a request of a file containing image preview identification information and an image script; the matching module is used for judging whether the image script is matched with the image preview identification information contained in the file data or not when the file data is received, if so, turning to the next step, and if not, sending a printing fault code; and the printing module is used for printing the file data after the matching is successful. The invention solves the problems of offset and deficiency in the printing image of the printer, only extracts the characteristic points of the preview image without global scanning, has higher calculation speed and greatly improves the speed of printing the image.
Description
Technical Field
The invention relates to the technical field of printers, in particular to a printing control platform of a printer.
Background
A printer is one of the output devices of a computer for printing the results of a computer process on an associated medium. The indexes for measuring the quality of the printer comprise three items: print resolution, print speed and noise. The existing printer has high stability of printing characters, but is easy to generate offset and deficiency when printing images, thereby reducing the reliability of image printing.
Disclosure of Invention
The invention aims to overcome the defects and provide a printing control platform of a printer.
A print control platform of a printer includes the following:
the script generating module is used for starting image printing, reading image preview identification information of printed paper and generating a printed image script;
the sending module is used for sending a request of a file containing image preview identification information and an image script;
the matching module is used for judging whether the image script is matched with the image preview identification information contained in the file data or not when the file data is received, if so, turning to the next step, and if not, sending a printing fault code;
and the printing module is used for printing the file data after the matching is successful.
Further, the matching module includes:
the extraction module is used for determining the homonymous points of all the characteristic points in the image script and extracting matching point pairs;
the retrieval module is used for determining the coordinates of each feature point on the preview image and determining a retrieval radius according to the coordinates;
and the comparison module is used for comparing the feature description vectors of the feature points with the feature description vectors of each point in the retrieval range on the preview image one by one, and marking the row-column number coordinates of the matched points with the same name on the preview image.
Further, the comparison module is specifically configured to set a feature description vector of the feature point as Vf, a feature description vector of a certain point in a corresponding search range on the preview image as Vf ', and a matching degree between the two feature description vectors Vf and Vf' is determined by the following formula:
wherein sNo is the length of the feature description vector Vf; ve is a row vector of equal length to the feature description vector and all 1 values. A larger match value indicates a higher degree of match between the two feature description vectors.
The invention solves the problems of offset and deficiency in the printing image of the printer, only extracts the characteristic points of the preview image without global scanning, has higher calculation speed and greatly improves the speed of printing the image.

Detailed Description
The following description will be made of a print control platform of a printer according to the present invention with reference to the accompanying drawings and embodiments of the present invention.
Example (b): a print control platform of a printer includes the following:
the script generating module is used for starting image printing, reading image preview identification information of printed paper and generating a printed image script;
the sending module is used for sending a request of a file containing image preview identification information and an image script;
the matching module is used for judging whether the image script is matched with the image preview identification information contained in the file data or not when the file data is received, if so, turning to the next step, and if not, sending a printing fault code;
and the printing module is used for printing the file data after the matching is successful.
The matching module includes:
the extraction module is used for determining the homonymous points of all the characteristic points in the image script and extracting matching point pairs;
the retrieval module is used for determining the coordinates of each feature point on the preview image and determining a retrieval radius according to the coordinates;
and the comparison module is used for comparing the feature description vectors of the feature points with the feature description vectors of each point in the retrieval range on the preview image one by one, and marking the row-column number coordinates of the matched points with the same name on the preview image.
The comparison module is specifically used for setting the feature description vector of the feature point as Vf, the feature description vector of a certain point in the corresponding retrieval range on the preview image as Vf ', and the matching degree between the two feature description vectors Vf and Vf' is determined by the following formula:
wherein sNo is the length of the feature description vector Vf; ve is a row vector of equal length to the feature description vector and all 1 values. A larger match value indicates a higher degree of match between the two feature description vectors.
