example 1
[0053] "ocrName": "totleMoney",
[0054] "ocrValue": "198.00",
[0055] "businessFlag": "1",
[0056] "ocrReusltDet": false,
[0057] "businessValue": "300.00"
[0058] In Example 1, the amount is wrongly recognized, the business data is 300, and the model recognition is 198. Therefore, the marker model identifies errors.
example 2
[0060] "ocrName": "ticketsMoney",
[0061] "ocrValue": "192.23",
[0062] "businessFlag": "1",
[0063] "ocrReusltDet": true,
[0064] "businessValue": "192.23"
[0065] In example 2, identify the amount, the business data is 192.23, and the model identification is 192.23. Therefore, the marker model is identified correctly.
[0066] After the field information is generated from the data information, the system can easily find the model data information marked as wrong from the field information. For example, in the above two examples, the field information of "ocrReusltDet": false is searched directly. When the model data information marked as error is found, the corresponding error data information is obtained. Finally, according to the model data information marked as error, the general character recognition result with coordinates is restored. Such as image 3 As shown, the wrong model data information on the right side of the figure is restored to the general text...

Abstract
The invention discloses a model correction method and correction system, which can improve the recognition rate of a model. The model correction method comprises the steps that data information is collected from a picture, and the data information comprises correct data information that service data and model identification data are consistent and error data information that the service data and the model identification data are inconsistent; judging whether the error data information is a model identification error or not, and if so, entering the next step; and performing model antisense according to the error data information, automatically marking, and training a model.
Description
technical field [0001] The invention belongs to the field of model correction, and in particular relates to a model correction method and a correction system. Background technique [0002] At present, most of the invoice reimbursement, scanning, and review in the financial shared office field still adopt manual review. Financial personnel are faced with the process of receiving, sorting, scanning, reviewing, and replying to physical invoices every day. The entire process line is boring, and there are a lot of repetitive manual operations, especially the bill review. It is necessary to repeatedly compare whether the reimbursement process information reported by employees is consistent with the bill information, which is time-consuming and laborious. [0003] The traditional ocr recognition is based on the attention_ocr technology to complete the general recognition model. Through the continuous marking training of the marking platform, the text recognition results from left ...
