Embodiment 1

[0057] see figure 1 , shows the method for exporting an image table in the first embodiment of the present invention, the method includes steps S101 to S104:

[0058] S101, acquiring outline information of a table in a scanned image;

[0059] In the present application, the outline information includes position information and size information, the position information includes frame data, and the size information includes wireframe data, that is, cell data information in a table.

[0060]S102, divide the table into rows and columns based on the outline information, and obtain row and column information and row and column index numbers of the table;

[0061] S103, comparing the row and column index numbers with the row and column information, and judging whether there is a merge relationship between the rows and columns of the table;

[0062] In this application, the row and column information of the cell is extracted, the height and column width of each row of the cell are ...

Embodiment 2

[0091] Please check Figure 8 Shown is a system for exporting an image form in the second embodiment of the present invention, including:

[0092] Obtaining module 11, for obtaining the contour information of the table in the scanned image;

[0093] The division module 12 divides the table into rows and columns based on the outline information, and obtains the row and column information and the row and column index numbers of the table;

[0094] Judging module 13, configured to compare the row and column index numbers with the row and column information, and judge whether there is a merge relationship between the rows and columns of the table

[0095] The output module 14 is configured to split and output the table when the rows and columns of the table are merged.

[0096] Optionally, the division module 12 includes:

[0097] The first extraction unit is used to extract cells belonging to the same row according to the value of the ordinate of the left vertex of the cell; ...

Embodiment 3

[0120] The present invention also provides a computer device, please refer to Figure 9 , shows a data processing device among the third embodiment of the present invention, including a memory 20, a processor 10, and a computer program 30 stored in the memory and operable on the processor, and the processor implements the program when executing the program Data processing method as above.

[0121] Wherein, the processor 10 may be a central processing unit (Central Processing Unit, CPU), a controller, a microcontroller, a microprocessor, or other data processing chips in some embodiments, and is used to run program codes stored in the memory 20 or Processing data, such as executing access restriction programs, etc.

[0122] Wherein, the memory 20 includes at least one type of readable storage medium, and the readable storage medium includes flash memory, hard disk, multimedia card, card type memory (for example, SD or DX memory, etc.), magnetic memory, magnetic disk, optical d...

Abstract

The invention provides an image table exporting method and system, a storage medium and equipment. The method comprises the steps: obtaining contour information of a table in a scanned image; performing row and column division on the table based on the contour information to obtain row and column information and row and column index serial numbers of the table; comparing the row and column index serial numbers with the row and column information, and judging whether rows and columns of the table have a merging relationship; and if so, splitting the table according to the row and column index serial numbers and the row and column information and outputting the table. According to the scheme, by detecting the contour information of the table in the scanned image, dividing the table into rowsand columns of cells and intercepting the divided row and column information for recognition, the accuracy and position accuracy of character recognition are effectively improved; in addition, the merging relation of the cells is calculated, so that an identification result can be exported as a table file for a user to perform further data analysis; and the technical problem that in the prior art, a scheme for determining the table position through the intersection relation of straight lines cannot identify cell merging information is solved.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a method, system, storage medium and equipment for exporting an image form. Background technique [0002] With the in-depth development of image text, more and more types of image text data have been included in the category of image text recognition. Among them, tables are the most streamlined expression method for summarizing text data records, and their wide application in all walks of life is self-evident. Metaphor. [0003] Among the existing technologies, the OCR text recognition (Optical Character Recognition, optical character recognition) technology adopted is based on Tesseract, a popular open source OCR engine. The line is not an ideal straight line in the scanned image, and the merged information of the cells cannot be recognized. It is difficult to completely avoid the interference of the table by removing the straight line, and the recognized coordinate p...
