For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] For the purpose of simplicity and illustration, the principles of the embodiments are mainly described by reference to examples. In the following description, many specific details are proposed to provide a thorough understanding of the embodiments. However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, known methods and structures are not described in detail to avoid making these embodiments unnecessarily difficult to understand. In addition, all embodiments can be used in combination with each other. Example 1

[0025] like Figure 1As shown, this embodiment provides a data collection method based on intelligent recognition and filling of medical documents, wherein the method is applied to a data collection system based on intelligent recognition and filling of medical documents, and the method includes: S10, configuring key detection parameters of the target medical document based on the OCR tool, wherein the key detection parameters include detection limit side length, detection directory, detection image shape and detection text length; It should be noted that the OCR (Optical Character Recognition) tool refers to an electronic device that detects characters on medical documents by detecting dark and light patterns, that is, it uses an optical method to recognize the text in the medical document. Before recognition, the key detection parameters in the medical document are configured to make the OCR tool more suitable for the recognition of medical documents. The following are some key parameters and their configurations in the key detection parameters: Detection limit side length: Set the maximum side length of the image during detection to adapt to the size of the medical document; Detection directory: specifies the path of the detection model. You can select or train a specific detection model based on the characteristics of the medical document; Detect image shape: Set the shape of the image during recognition to fit the size and proportion of the text on the medical document; Detection text length: Set the maximum text length considered during recognition to accommodate long text that may appear on medical documents.

[0026] S20, obtaining a medical document sample, analyzing and counting the document information categories based on the medical document sample, where the document sample information categories include the medical document date, patient name, drug name, and diagnosis information; S30, based on the document information category, dividing the document information category area corresponding to the location of the medical document sample, setting a regional identification mark according to the document information category area, and establishing a regional logical association according to the regional identification mark, wherein the document information category corresponds to the document information category area one by one; Specifically, a large number of medical document samples are collected, analyzed and counted, including frequently appearing and key information categories in each document, including date, patient name, drug name, medical institution name, diagnosis and treatment items, cost details, etc., without limitation; In order to determine the fields to be extracted, the corresponding areas are delineated on the template according to the format of the medical document sample and the actual position of each information category in the medical document sample, namely, the document information category area. For example, the date is usually located in the upper right or upper left corner of the document, the patient's name is immediately after the specific identity identification area, and the drug name is mostly in the drug list part; Secondly, a unique area identification mark is set for each document information category area so that the identified text and the corresponding field can be accurately matched when the text information is extracted later. This setting method can use image recognition or manual labeling, and at the same time establish regional logical associations, that is, the logical associations between the various document information category areas, such as the corresponding billing relationship between the cost details area and the diagnosis and treatment item area, and the patient name area is associated with the identity verification area to ensure completeness and accuracy.

[0027] S40, establishing a medical document extraction template based on the regional identification mark and the regional logical association; S50, using the key detection parameters and OCR tools to identify the target medical document and obtain the medical document text information; S60: Extract based on the medical document text information and the medical document extraction template, generate key information of the medical document, mark the key information of the medical document and fill it into the system accordingly.

[0028] Specifically, the key information of the medical document is extracted according to the medical document extraction template through the identified text, that is, the text information of the medical document, and the extracted key information of the medical document such as the date, patient name, and drug name is mapped to the corresponding fields in the template to complete the identification and extraction of the target medical document. The extracted key information of the medical document is then marked and filled in the system accordingly.

[0029] Furthermore, the method further comprises: Identify based on the key information of medical documents and the sensitive information database, analyze the key information of medical documents with the sensitive keywords in the sensitive information database to find out whether there is a match; If there is a match, the sensitive keywords corresponding to the key information of the medical document are fuzzy processed.

[0030] By using the medical document key information and sensitive information database for identification in the above method, it is possible to automatically identify whether there is patient sensitive information in the medical document key information. If relevant sensitive information exists, the sensitive information is automatically coded. It should be noted that the sensitive information database and sensitive keywords are pre-set; secondly, considering special scenarios, users can also be supported to manually adjust the coded content, which can greatly reduce the risk of patient information leakage and the manual workload of patient information desensitization.

[0031] Furthermore, the method also includes: based on the medical document sample, detecting and identifying the document table in the medical document sample, and segmenting the document table into document cells; separating the text information in the document cell according to the contrast difference between the document cell and the medical document sample, and generating a text binary image; inputting the text binary image into the OCR recognition module for recognition to extract the document information category.

[0032] Specifically, the text binary image is input into the OCR recognition module for recognition. Exemplarily, the recognition process can recognize the text in the text binary image in combination with the medical field vocabulary library to ensure that the text content can be accurately extracted, and the document information category is obtained after recognition.

[0033] Furthermore, the method further comprises: Obtaining a target medical document, and performing image preprocessing operations according to the target medical document; Among them, the preprocessing operation includes the following specific steps: grayscale processing is performed on the target medical document to convert the collected document color image into a document grayscale image; the document grayscale image is filtered and denoised, and the median value within the pixel field of the document grayscale image is selected as the current pixel value to remove the noise in the document grayscale image and generate a document denoised image; the document denoised image is binarized to obtain the target medical document after the image preprocessing operation.

[0034] Specifically, the target medical document is subjected to image preprocessing to ensure image quality optimization. First, grayscale processing is used to convert the collected document color image into a document grayscale image, that is, the color image is converted into a grayscale image to reduce the interference of color information on subsequent processing. Secondly, the document grayscale image is filtered and denoised, and the median value within the pixel field of the document grayscale image is selected as the current pixel value to remove the noise in the document grayscale image. The noise can be salt and pepper noise and Gaussian noise, etc., so that the edge of the document grayscale image is clearer, which is more suitable for subsequent recognition, and a document denoised image is generated. Finally, the document denoised image is binarized to obtain the target medical document after image preprocessing, that is, the target medical document is converted into only black and white colors, the contrast between the text and the background is enhanced, the text part is more obvious, and the text information is more suitable for recognition and extraction.

[0035] After the image preprocessing operation, the target medical document uses a detection module to detect the straight line of the document image to determine whether the straight line of the document image meets the preset tilt angle. If so, a rotation matrix is ​​used to perform rotation correction on the straight line of the document image.

[0036] Specifically, the target medical document after the image preprocessing operation is detected by a detection module. The inclination angle of the document image straight line in the target medical document is determined by the detection module, and it is analyzed whether the document image straight line meets the preset inclination angle. If so, the document image straight line is rotationally corrected by a rotation matrix, so that the document image straight line, that is, the text line, in the target medical document remains horizontal, which is convenient for the subsequent extraction of text information.

[0037] Furthermore, the method also includes: determining whether the confidence of the key information of the medical document is lower than a preset confidence, and generating a confidence determination result; comparing the recognition result of the key information of the medical document with the preset key information of the document, and generating a key information comparison result; summarizing the confidence determination result and the key information comparison result and feeding them back to the system.

[0038] When the confidence of the key information of a medical document is lower than the preset confidence, the confidence judgment result is uncertain content, otherwise the confidence judgment result is certain content; when there is a missing in the recognition result of the key information of a medical document compared with the preset document key information, the key information comparison result is missing key information, otherwise the key information comparison result is complete key information.

[0039] Specifically, it is determined whether the confidence of the key information of the medical document is lower than the preset confidence, and a confidence determination result is generated. When the confidence of the key information of the medical document is lower than the preset confidence, the confidence determination result is uncertain content, otherwise the confidence determination result is certain content. For example, when the confidence of the OCR recognition result is lower than the preset confidence, assuming it is lower than 70%, the confidence determination result is uncertain content. Compare the recognition result of the key information of the medical document with the preset key information of the document, and generate the key information comparison result. When there is a missing in the comparison between the recognition result of the key information of the medical document and the preset key information of the document, the key information comparison result is the key information missing. Otherwise, the key information comparison result is the key information complete. For example, if the key fields "drug name" and "diagnosis information" do not appear in the recognition result, the key information comparison result is marked as the key information missing. The marked confidence judgment results and key information comparison results are summarized and fed back to the system. The summary can be sorted according to urgency and importance, with more urgent and important data placed in front. During manual review, they are verified and corrected in order of priority. After the correction is completed, it is fed back to the system to update the corresponding data to ensure the accuracy of the identified and extracted content.

[0040] The present application uses an OCR tool to configure key detection parameters of a target medical document; obtains a medical document sample, analyzes the medical document sample and counts the document information category; based on the document information category, divides the document information category area corresponding to the location of the medical document sample, sets a region identification mark according to the document information category area, and establishes a region logical association based on the region identification mark; establishes a medical document extraction template based on the region identification mark and the region logical association; uses key detection parameters and an OCR tool to identify the target medical document and obtain medical document text information; extracts the medical document based on the medical document text information and the medical document extraction template, generates medical document key information, and fills the medical document key information into the system accordingly, thereby achieving the technical effect of being able to accurately locate the text area and accurately extract the text content, and solves the technical problem that conventional OCR tools are difficult to accurately locate the text area, resulting in incorrect text content extraction.
