Embodiment Construction

[0076] The present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0077] Such as Figure 1-Figure 6 As shown, the present invention provides a method for checking whether a check box is checked in a paper prescription document, which mainly includes the following steps:

[0078] (1) Image acquisition of the prescription receipt to obtain a positive color image of the prescription receipt;

[0079] (2) Extract the front color image of the prescription receipt, and convert the front color image into a grayscale image of the receipt through the color-to-grayscale algorithm; where the color-to-grayscale algorithm uses a general grayscale method to obtain the grayscale of the receipt image.

[0080] (3) Calculate the inclination angle of the grayscale image of the document, and correct the inclination of the grayscale image of the document;

[0081] In the step (3), the inclination correction is performed on t...

Abstract

The invention discloses a method of detecting whether a checkbox is selected in a paper prescription document, belonging to the technical field of image processing. The method mainly comprises the following steps of (1) collecting an image of a prescription document so as to obtain a front color image; (2) extracting the front color image of the prescription document, and converting the front color image into a document grayscale image; (3) calculating an angle of inclination of the document grayscale image, and performing inclination correction; (4) identifying page identification on the document grayscale image; (5) performing binarization on the document grayscale image so as to obtain a document binary image; (6) creating a positioning template, and determining an initial positioning range of each checkbox according to relative positions of each document feature area configured in the positioning template and each checkbox area; (7) positioning each checkbox accurately; and (8) determining whether each checkbox is selected. The method of automatically detecting whether the document image checkbox is selected has high detection efficiency and high identification rate and is stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of image processing, and specifically relates to a method and system for detecting whether a check box is checked in a paper prescription document. Background technique [0002] Paper prescription documents refer to the medical documents issued by registered medical practitioners and assistant medical practitioners for patients in diagnosis and treatment activities, reviewed, prepared and checked by pharmaceutical professional and technical personnel who have obtained the qualifications for professional and technical positions in pharmacy, and used as medical certificates for patients. paperwork. A prescription is a written document for a doctor to administer a drug to a patient, and it is the basis for a pharmacist to dispense drugs, and it has legal, technical, and economic responsibilities. [0003] Some element units of paper prescription documents are in the form of check boxes. Units or individuals ne...
