Table recognition overprinting method, computer equipment and computer readable storage medium

Abstract

The invention relates to a table recognition overprinting method, computer equipment and a computer readable storage medium. The method comprises the steps: obtaining a to-be-recognized table image, carrying out the preprocessing of the collected table image, and obtaining a preprocessed first target image; performing correction processing on the preprocessed first target image to obtain a secondtarget image; extracting a table contour of the second target image and carrying out refinement processing to obtain a third target image; analyzing the transverse and longitudinal structures of the table according to the third target image to obtain table row and column structure information; recognizing the angular point position of the third target image through angular point detection, and determining the cell position information in the table in combination with the table row and column structure information; outputting cell position information in the table. By means of the table printing method, the table can be recognized and printed in a sleeved mode, data information in the table is removed, the office efficiency of people is improved by automatically printing the table in a sleeved mode through a computer, and the purpose that the needed table can be printed only through table pictures is achieved.

Description

technical field [0001] The invention relates to the technical field of form printing, in particular to a form identification printing method, computer equipment and a computer-readable storage medium. Background technique [0002] In modern society, many industries have very strict specifications and restrictions on various forms and bills. The format cannot be changed without authorization. Once changed, it will become invalid. Therefore, under normal circumstances, it is necessary to manually design various forms first. , and then use it, this approach is not only inefficient, but also time-consuming and labor-intensive. There are also methods for form image recognition in the prior art. For example, the method of extracting form lines using the form line intersection analysis method is too time-consuming and has poor stability. A method and device for transforming an image, which uses a table line intersection analysis method for table recognition, selects at least one c...

[0002] In modern society, many industries have very strict specifications and restrictions on various forms and bills. The format cannot be changed without authorization. Once changed, it will become invalid. Therefore, under normal circumstances, it is necessary to manually design various forms first. , and then use it, this method is not only inefficient, but also time-consuming and labor-intensive

There are also methods for form image recognition in the prior art. For example, the method of extracting form lines using the form line intersection analysis method is too time-consuming and has poor stability. A method and device for transforming an image, which uses a table line intersection analysis method for table recognition, selects at least one cell corresponding to a position from the image to be recognized and the template image, and confirms at least one cell from the selected cells respectively Four vertices located on the outer border, the vertices confirmed in the image to be identified correspond to the positions of vertices confirmed in the template image, forming at least four sets of corresponding vertex coordinates, etc. The identification process is relatively complicated and stable poor
