Embodiment 1
[0055] see figure 1, shows the text recognition method in the first embodiment of the present invention, the text recognition method can be implemented by software and / or hardware, and the method specifically includes steps S01-step S04.
[0056] Step S01, acquiring an image to be recognized.
[0057] Specifically, when the document to be identified is a paper document (such as printed matter), it can be converted into an image to be identified in the corresponding format by taking a photo or scanning. When taking a photo or scanning a paper document, try to ensure that the paper quality Documents should be placed flat and free of obvious stains on the surface to minimize noise interference in subsequent images. When the file to be identified belongs to an electronic file (such as PDF format) but not an image format, the file to be identified can be converted into an image to be identified in a corresponding format by means of image conversion.
[0058] Step S02 , using a pr...
Embodiment 2
[0067] see figure 2 , shows the text recognition method in the second embodiment of the present invention, the text recognition method can be implemented by software and / or hardware, and the method specifically includes steps S1-step S5.
[0068] Step S1, acquiring an image to be recognized, and performing preprocessing on the image to be recognized.
[0069] In this embodiment, the image to be recognized is converted from a paper document, and the specific conversion process is: converting the text into a pdf document by taking pictures or scanning, and then converting the pdf document through measures such as resolution control and file size filtering. Perform format parsing and convert to images to be recognized in specific formats (such as jpg, png, etc.).
[0070] Wherein, the preprocessing manner includes one or more of image size normalization, grayscale processing, binarization processing, bilateral filtering processing, mathematical morphology processing, and image ...
Embodiment 3
[0131] Another aspect of the present invention also provides a text recognition device, please refer to image 3 , shows the text recognition device in the third embodiment of the present invention, the text recognition device includes:
[0132] An image acquisition module 11, configured to acquire an image to be identified;
[0133] The information recognition module 12 is used to use a preset image recognition model to perform text and form recognition on the image to be recognized, so as to extract the text data, table structure and their respective coordinate information in the image to be recognized;
[0134] The area segmentation module 13 is used to segment the connected area of the table structure based on the preset area segmentation module, so as to identify the effective rectangular area defined by the table structure, and determine the effective rectangular area according to the coordinate information of the table structure. Coordinate information of the rectang...
