In operation S210, a category recognition is performed on a document picture to obtain a target category result.
In operation S220, a target structured model matched with the target category result is determined.
In operation S230, a structure recognition is performed on the document picture to obtain a structure recognition result by using the target structured model, so as to generate an electronic document based on the structure recognition result, where the structure recognition result includes a field attribute recognition result and a field position recognition result.
According to embodiments of the present disclosure, the document picture may be a picture of a paper document. For example, the document picture may be a picture obtained by collecting an information in the paper document, and the object image of the document picture may have a same content as a text content in the paper document.
According to embodiments of the present disclosure, a category of the document picture may refer to a category of the paper document, which may be, for example, an identity card or a bank card. However, the category is not limited to this, and may also be a receipt, a contract, and other categories.
According to embodiments of the present disclosure, different categories of document pictures may have different field structures, such as field attributes and field positions. A category recognition may be performed on the document picture to obtain a target category result, and then a subsequent method of processing the document picture may be determined. For example, it is possible to determine a target structured model based on the target category result. Therefore, the processing of the document picture may be more targeted.
According to embodiments of the present disclosure, the target structured model may be a structured model matched with the target category result. A plurality of structured models may be obtained by pre-training, and the plurality of structured models may correspond to a plurality of different categories of document pictures one by one.
According to embodiments of the present disclosure, the structured model may be used to perform a structure recognition on the document picture to obtain a structure recognition result, such as a field attribute recognition result and a field position recognition result.
According to embodiments of the present disclosure, the object image of the document picture generally contains data of a plurality of field structures. For example, an object image of a document picture of an identity card generally includes a name field, an identity number field, an address field, a validity term field, and other different attribute fields. Different fields may be distinguished through the structure recognition, and an importance level may be determined based on the field attribute recognition result, for example, it may be distinguished that whether a field is required or optional. In addition, the field position recognition result may be obtained through the structure recognition, and a corresponding field text may be easily extracted using the field recognition result, so that the extracting of data may be more targeted.

The electronic document is finally generated by using the field attribute recognition result and the field position recognition result, so as to obtain data that may be processed by a computer, which is convenient for storage and application.
According to embodiments of the present disclosure, the target structured model is determined from the plurality of structured models by using the target category result, and the model matched with a structure recognition method of the document picture may be clearly determined without a manual intervention, so as to liberate manpower, improve a processing efficiency, and improve a recognition accuracy.
The method shown in
As shown in
In operation S310, a category recognition is performed on the document picture to obtain a category result.
In operation S320, a target category result matched with the category result is recognized from at least one template category.
In operation S331, an operation of determining a target structured model matched with the target category result is performed in response to determining that the target category result is detected.
In operation S332, the operation is stopped in response to determining that no target category result is detected.
According to embodiments of the present disclosure, a set of template categories may be preset, and the set of template categories includes at least one template category. The at least one template category may correspond to at least one category of at least one document picture one by one.
According to embodiments of the present disclosure, the document picture may be a picture of a paper document, but is not limited thereto, and may also be a picture of an electronic document. The category of the document picture may be the same as a category of the corresponding paper document or a category of the corresponding electronic document. For example, it may be at least one selected from a contract, a receipt, an invoice, a certificate, a record, a file, a leaflet, or other categories.
According to embodiments of the present disclosure, different categories of document pictures may have different field structures. For example, a field attribute and a field position in a document picture of an identity card are different from a field attribute and a field position in a document picture of a contract. Therefore, at least one template category may be preset to be in one-to-one correspondence with at least one structured model. Each template category is configured with a corresponding structured model. In other words, corresponding structured models are configured for different categories of document pictures to perform structure recognition processing. Furthermore, the target structured model is determined using the target category result, and the structure recognition operation is performed using the target structured model, so that the method is more targeted and a problem of a low recognition accuracy caused by the use of a general model may be avoided.
According to embodiments of the present disclosure, in a case that no target category result is detected, an operation of rejecting recognition may be performed, that is, an execution of the subsequent structure recognition operation is stopped, so as to improve the processing efficiency.
According to embodiments of the present disclosure, an object classification model may be used to perform the category recognition on the document picture to obtain the target category result.
According to embodiments of the present disclosure, a network architecture of the object classification model is not limited. For example, the object classification model may be obtained using a convolutional neural network (CNN) as a core network in combination with a bidirectional long short-term memory network (BiLSTM). However, the present disclosure is not limited to this, as long as the model may use the document picture as input data and use the target category result as output data.
According to embodiments of the present disclosure, a preprocessing operation of an image correction may be performed before performing the operation S220 of determining the target structured model matched with the target category result. For example, an image direction of the document picture may be recognized. If the image direction is not matched with a target direction, a rotation correction may be performed on the document picture. If the image direction is matched with the target direction, the subsequent operation S220 may be performed directly.
According to embodiments of the present disclosure, the image direction may refer to a direction of a character in the object image of the document picture.
According to embodiments of the present disclosure, the target direction may refer to a predetermined direction. For example, a predetermined horizontal direction or vertical direction may be the target direction.
According to exemplary embodiments of the present disclosure, a readable direction of a predetermined character, such as a horizontal direction, may be the target direction.
As shown in
It should be noted that the preprocessing operation of the image correction may be performed after the category recognition operation is performed or before the category recognition operation is performed, as long as it is performed before determining the target structured model matched with the target category result.
According to exemplary embodiments of the present disclosure, the image direction of the document picture may be recognized by using a direction determination model. For example, the direction determination model may be used to recognize the image direction of the document picture to obtain an angle result of the image direction relative to the target direction, for example, an angle result of 0 degree, 90 degrees, 180 degrees, 270 degrees, or the like. The rotation correction may be performed on the document picture according to the angle result, so as to obtain the rotation-corrected document picture.
According to embodiments of the present disclosure, a network architecture of the direction determination model is not limited, for example, an affine transform function in an OpenCV algorithm may be used. However, the present disclosure is not limited to this, and it is also possible to combine the OpenCV algorithm with a Python algorithm, as long as the model may use the document picture as input data and use the rotation-corrected document picture as output data.
With the preprocessing operation of the image correction provided by embodiments of the present disclosure, it is possible to avoid a problem of a reduction of an accuracy of the subsequent structure recognition caused by a fact that the image direction of the document picture is not conductive to a character recognition.
It should be noted that, in embodiments of the present disclosure, the method of generating the document is not limited to including the preprocessing operation of the rotation correction, but may also include a transformation correction. For example, images with different degrees of angle inclination may be processed through a pre-processing operation of transformation correction, so as to reduce an interference caused by the angle inclination.
According to exemplary embodiments of the present disclosure, a preprocessing operation of cropping may also be performed.
For example, before the operation S210 of performing the category recognition on the document picture to obtain the category result: an object detection may be performed on an initial picture to obtain an object position result, and the document picture may be obtained from the initial picture based on the object position result.
According to embodiments of the present disclosure, the object detection may refer to detecting an object image of the initial picture. For example, an initial picture of an identity card may be obtained by capturing an image of an identity card using a camera, and a large number of unnecessary regions may exist around the image of the identity card. For another example, reserved blank regions may exist on both sides of a text and above and below the text in an initial picture of a contract. Through the object detection, an object image region having a character may be distinguished from an unnecessary region.
According to embodiments of the present disclosure, for example, the object image region having a character may be used as the object position result.
According to embodiments of the present disclosure, based on the object position result, the document picture may be obtained from the initial picture by means of cropping, and the initial picture may be cropped without manual intervention to remove the unnecessary region, so that a background interference may be eliminated, a complexity of image processing may be reduced, and the category of the document picture may be recognized more accurately.
According to exemplary embodiments of the present disclosure, the object detection may be performed on the initial picture by using an object detection model to obtain the object position result, and the document picture may be obtained from the initial picture based on the object position result.
According to embodiments of the present disclosure, a network architecture of the object detection model is not limited, for example, an OpenCV algorithm may be used. However, the present disclosure is not limited to this, and a general algorithm such as Python and Ruby may also be used, as long as the model may use the initial picture as input data and use the document picture as output data.
According to embodiments of the present disclosure, the operation S230 of performing the structure recognition on the document picture by using the target structured model so as to obtain the structure recognition result may be performed through the following operations.
For example, the structure recognition may be performed on the document picture by using a target structured model, and the structure recognition result may be determined from a plurality of initial field structures.
According to embodiments of the present disclosure, the target structured model may be a structured model matched with the target category result. A plurality of structured models may be obtained by pre-training, and the plurality of structured models may correspond to a plurality of different categories of document pictures one by one.
According to embodiments of the present disclosure, the structured model may be used to perform the structure recognition on the document picture to obtain the structure recognition result, such as a field attribute recognition result and a field position recognition result.
According to embodiments of the present disclosure, a network architecture of the structured model is not limited, for example, a structured model obtained by CTPN (Connectionist Text Proposal Network) may be used. However, the present disclosure is not limited to this, and the structured model may also be a structured model obtained by combining a convolutional neural network and an RPN network (Region Proposal Network), as long as the model may use the document picture or the rotation-corrected document picture as input data and use the structured recognition result as output data.
As shown in
According to embodiments of the present disclosure, a key content and a target content may be recognized and determined from the document picture by using the target structured model. For example, a field text required to generate an electronic document may be determined through the target structured model without manual intervention. In addition, the field attribute recognition result and the field position recognition result may provide a basis for subsequent field text extraction and text recognition, and therefore a coherent processing flow may be formed.
According to embodiments of the present disclosure, the following operation may be performed after the operation S230 of performing the structure recognition on the document picture by using the target structured model so as to obtain the structure recognition result.
For example, a target field text may be extracted based on the field position recognition result; and a text recognition may be performed on the target field text to obtain a text recognition result.
According to embodiments of the present disclosure, a text recognition model may be used to extract the target field text and perform the text recognition on the target field text, so as to obtain the text recognition result. For example, the corresponding image region acquired based on the field position recognition result may be input into the text recognition model to obtain the text recognition result. According to embodiments of the present disclosure, an electronic document may be generated based on the text recognition result. The electronic document may be stored in a centralized manner, which makes searching convenient and fast, and effectively prevents the document from being damaged and lost.
According to embodiments of the present disclosure, a network architecture of the text recognition model is not limited. For example, the text recognition model may be obtained using a convolutional neural network (CNN) as a core network in combination with an activation function such as softmax. However, the present disclosure is not limited to this, and the text recognition model may also be obtained by combining a convolutional neural network and a recurrent neural network (RNN), as long as the model may use the corresponding image region acquired based on the field position recognition result as input data and use the text recognition result as output data.
