Description

Technical Field

[0001] The present invention relates to the technical field of smart card making, and in particular to a certificate making method and a card making system for a smart terminal. Background Art

[0002] When making a social security card, user information must be collected first. Under the guidance of the staff, the user collects social security information through the smart terminal device. When collecting social security information, the user's ID photo information needs to be collected, and when filling out the social security form, the user's portrait information needs to be collected. The existing social security card making method is to collect ID photo information and portrait information through the social security smart terminal device, send the photo information to the server for text extraction or cutout processing, and then send it to the manufacturer for card making. After the smart terminal itself performs text extraction or cutout processing, the smart terminal performs the card making operation. However, since the existing smart terminal devices may be portable smart terminals, their computing power and storage space are limited, and they cannot perform complex image processing tasks. If the image processing algorithm is deployed on the server, in order to ensure that the social security information collection can run smoothly in high-concurrency scenarios, multiple high-performance servers need to be configured, which increases the investment cost of the server.

[0003] An existing image detection method is to obtain an uploaded ID image and analyze the ID type of the ID image; if the ID type of the ID image is a predetermined ID type, the ID image is rotated so that the ID image is in an upright position; a binary image of the ID image in an upright position is obtained, and the key information area is obtained based on the binary image; a histogram of the ID image in an upright position is obtained, and the highlight area of ​​the ID image is obtained based on the histogram; it is analyzed whether there is an overlapping area between the key information area and the highlight area, and if there is an overlapping area between the key information area and the highlight area, it is analyzed whether the overlapping area is a reflective area; if so, it is prompted to re-upload the ID image, and if not, the ID image is sent to the server for identification. When the image processing method is that if the ID photo is reflective, it can be re-photographed, thereby improving the efficiency of ID image recognition, the server still needs to identify the original ID image, and the computing pressure of the server is not reduced. Secondly, after the ID photo is recognized on the server, the smart terminal cannot obtain the ID photo information recognized by the server, and the card making operation cannot be completed on the smart terminal. Summary of the invention

[0004] The first object of the present invention is to provide a method for producing a certificate of an intelligent terminal which reduces the computing pressure of a server.

[0005] The second object of the present invention is to provide a card making system using the certificate making method of the above-mentioned intelligent terminal.

[0006] To achieve the first objective of the present invention, the present invention provides an image processing method for information collection, characterized in that the method comprises: the intelligent terminal acquires an ID photo image, performs preliminary processing on the ID photo image, and the steps of the intelligent terminal performing preliminary processing on the ID photo image include: performing angle correction and edge detection on the ID photo image, cropping the ID photo image to form an initial ID photo image, and sending the initial ID photo image to an image processing server; the image processing server extracts ID information from the initial ID photo image and sends the ID information to the intelligent terminal; the intelligent terminal acquires a portrait image, performs preliminary processing on the portrait image to form an initial portrait image, and sends the initial portrait image to the image processing server. The image processing server performs cutout processing on the initial portrait image and sends the cutout portrait information to the intelligent terminal.

[0007] It can be seen from the above scheme that after obtaining the ID photo image or the portrait image on the smart terminal, the image is preliminarily processed, such as performing angle correction and edge detection on the ID photo image, cropping the ID body, or performing angle correction, denoising and compression on the portrait image. When the preliminary processing is performed on the smart terminal, the processing method is relatively simple and does not involve complex algorithms. When it is necessary to extract text and cut out the ID image, a complex image processing model is used on the server for processing. Because when performing the preliminary processing on the smart terminal, the image is adjusted in angle so that the target object is consistent with the image coordinate system, the image is cropped and denoised, thereby reducing the noise of the image, and when the image is compressed, the amount of image data is reduced, so that the server can reduce the computing pressure of the server when processing the initial ID photo image and the initial portrait image. Secondly, the recognized information is returned to the smart device, so that the smart device can obtain the ID information and the cutout portrait information for card making, and the card making operation can also be realized when the processor processing performance of the smart device is limited.

[0008] In a further solution, after the smart terminal crops the ID photo image, it also performs: noise reduction processing and compression processing on the ID photo image.

[0009] It can be seen that noise reduction processing can reduce the noise of the image, and compression processing can reduce the amount of image data, which can reduce the computing pressure of the server when the server performs complex processing later.

[0010] In a further solution, after receiving the certificate information, the smart terminal also executes: filling the certificate information into the social security form.

[0011] It can be seen that the ID information includes the text information and portrait information of the ID photo image, which can be filled in the social security form to reduce the workload of the staff.

[0012] In a further solution, after the smart terminal fills in the certificate information in the social security form, it also executes: the smart terminal sends the certificate information to the social security server, determines whether the insurance confirmation information sent by the social security server is received, and if the insurance confirmation information is received, receives the remaining user insurance information.

[0013] It can be seen from this that the social security server can determine whether the user has ever participated in the insurance operation through the certificate information. If the user has never participated in the insurance, it can be confirmed that the user can participate in the insurance this time and send the insurance confirmation information to the server.

[0014] In a further solution, after receiving the cutout portrait information, the smart terminal further executes: adding the cutout portrait information to the social security form.

[0015] It can be seen from this that the smart terminal needs to use the cutout portrait information as the insured portrait information.

[0016] In a further solution, before the smart terminal sends the initial ID photo image to the image processing server, the smart terminal also executes: the smart terminal encrypts the initial ID photo image.

[0017] This shows that the smart terminal encrypts the initial ID photo image to improve the security of transmission.

[0018] In a further solution, the image processing server includes a cutout module and a certificate information extraction module.

[0019] It can be seen that the portrait image is cut out by the cutout module, and the text information is extracted by the certificate information extraction module.

[0020] In order to achieve the second purpose, the information collection system provided by the present invention includes an intelligent terminal and an image processing server. The intelligent terminal is used to obtain an ID photo image and perform preliminary processing on the ID photo image. The steps of the intelligent terminal performing preliminary processing on the ID photo image include: performing angle correction and edge detection on the ID photo image, cropping the ID photo image to form an initial ID photo image, and sending the initial ID photo image to the image processing server; the image processing server is used to extract ID information from the initial ID photo image and send the ID information to the intelligent terminal; the intelligent terminal is also used to obtain a portrait image, perform preliminary processing on the portrait image, form an initial portrait image, and send the initial portrait image to the server; the image processing server is also used to perform cutout processing on the initial portrait image and send the cutout portrait information to the intelligent terminal; the intelligent terminal obtains ID information and cutout portrait information, and uses the ID information and cutout portrait information for card making operations.

[0021] In a further solution, the social security collection system also includes a social security server, which is used to obtain certificate information sent by the smart terminal and send insurance confirmation information to the smart terminal based on the certificate information.

[0024] The present invention is further described below in conjunction with the accompanying drawings and embodiments. DETAILED DESCRIPTION

[0025] The certificate production method of the smart terminal provided by the present invention is that after the smart terminal obtains the image information, the image is first processed preliminarily on the smart terminal, and the image is angle corrected, denoised and compressed, and then sent to the server for deep image processing, such as text recognition and cutout processing. Since the image is preliminarily processed on the smart terminal, when the server performs high-precision deep image processing later, the computing pressure of the server is reduced, the processing efficiency of the server is improved, and the investment in server costs is reduced.

[0026] Card making system implementation example: See also Figure 1 The card making system of this embodiment includes an intelligent terminal 11, an image processing server 12 and a social security server 13. The intelligent terminal 11 is used to assist the staff in performing the card making operation after collecting the social security information of the user. The intelligent terminal 11 includes a processor 112, a camera module 111 and an image preliminary processing module 113. The camera module 111 is used to obtain the ID photo image and the portrait image. The processor 112 is used to process the collected information data. The image preliminary processing module 113 is used to perform preliminary processing on the ID photo image and the portrait image. The image processing server 12 includes a cutout module 121, an ID information extraction module 122 and a processing module 123. The cutout module 121 is used to perform cutout processing on the portrait image, the ID information extraction module 122 is used to extract information from the ID photo image, and the processing module 123 is used to receive image information and send the image information to the cutout module 121 and the ID information extraction module 122. The smart terminal 11 can query whether the user has ever participated in insurance through the social security server 13. If not, it will continue to collect user information to complete the form filling work.

[0027] Example of a method for making a certificate of a smart terminal: See also Figure 2, the certificate making method of the smart terminal of this embodiment is implemented by the card making system of the card making system embodiment. When the user needs to apply for a social security card, the social security information collection needs to be completed in the smart terminal under the guidance of the staff. First, step S1 is executed, the smart terminal obtains the certificate photo image, performs preliminary processing on the certificate photo image, forms an initial certificate photo image, and sends the initial certificate photo image to the image processing server. Among them, the preliminary processing operation on the certificate photo includes performing angle correction on the certificate photo image so that the angle of the certificate photo image is not tilted; edge detection is performed on the certificate photo, the certificate photo image is cropped, and the background information outside the certificate photo is removed. Since only the edge detection is performed on the certificate photo, and the edge of the certificate photo is straight and smooth, the certificate photo can be grayed, and a threshold is set so that the certificate photo regards the point in the image where the brightness change exceeds the threshold as an edge point to complete the edge detection. Of course, a simple edge algorithm can also be used to perform edge detection on the certificate photo; the certificate photo image is subjected to noise reduction processing to remove the noise of the certificate photo image; and the certificate photo image is compressed to reduce the data volume of the certificate photo image. Before the smart terminal sends the initial ID photo image to the image processing server, it also encrypts the initial ID photo image using an encryption key that is pre-agreed upon by the smart terminal and the image processing server.

[0028] After receiving the initial ID photo image, the image processing server first uses the encryption key to perform a decryption operation on the initial ID photo image, and then executes step S2, where the image processing server extracts the ID information from the initial ID photo image and sends the ID information to the smart terminal. The ID information is extracted by the ID information extraction module of the image processing server. The ID information extraction module is provided with a high-precision text extraction model, such as a text extraction model trained by a convolutional neural network or a recurrent neural network. Since the convolutional neural network and the recurrent neural network have a large computational pressure, the initial ID photo image after preliminary processing can reduce the data processing amount of the recurrent neural network.

[0029] After receiving the certificate information, the smart terminal fills the certificate information into the social security form, reducing the workload of the staff to fill in the information. After the smart terminal fills the certificate information into the social security form, the smart terminal sends the certificate information to the social security server. The social security server queries whether the user has an insurance record based on the certificate information. If there is an insurance record, it sends the information that the insurance cannot be obtained to the smart terminal. If there is no insurance record, it sends the insurance confirmation information to the smart terminal. The smart terminal determines whether it has received the insurance confirmation information sent by the social security server. If it has received the insurance confirmation information, it receives the remaining user insurance information. That is, after confirming the user's information, the staff fills in the remaining user insurance information in the social security form of the smart terminal, such as the insured unit, occupation, mobile phone number and other remaining user insurance information.

[0030] Since the social security form requires a user photo, the smart terminal needs to obtain the user's portrait image. That is, after the smart terminal obtains the remaining user insurance information, step S3 is executed, the smart terminal obtains the portrait image, performs preliminary processing on the portrait image, forms an initial portrait image, and sends the initial portrait image to the image processing server. Among them, the step of preliminary processing of the portrait image includes performing angle correction on the portrait image, so that the portrait of the portrait image is rotated to the correct position, making the portrait more obvious and easy to identify, and improving the recognition accuracy and recognition efficiency of the subsequent server's cutout processing; performing noise reduction processing on the portrait image to remove the noise of the portrait image and reduce the interference of noise on the subsequent server's cutout processing; compressing the portrait image to reduce the data volume of the portrait image and reduce the processing volume of the subsequent server's cutout processing.

[0031] After receiving the initial portrait image, the image processing server executes step S4, where the image processing server performs cutout processing on the initial portrait image and sends the cutout portrait information to the smart terminal. The image processing server performs cutout processing through a cutout module. The cutout module stores a high-precision cutout model, such as a cutout model obtained by training a generative adversarial network or a convolutional neural network. Since the initial portrait image has been angle-corrected, denoised, and compressed, the server can reduce the computing pressure of the server and improve the computing efficiency of the server when performing cutout processing.

[0032] After receiving the cutout portrait information, the smart terminal adds the cutout portrait information to the social security form. After the user confirms the information on the social security form, he signs to confirm and presses the submit button. After receiving the information submitted by the user, the smart terminal executes step S5, and the smart card uses the certificate information and the cutout portrait information for the card making operation, that is, the card making operation is performed according to the social security form. This allows the smart device to obtain the certificate information and the cutout portrait information for card making, and can also realize the card making operation when the processor processing performance of the smart device is limited.

[0033] The above are only preferred embodiments of the present invention, but the design concept of the invention is not limited thereto. Without departing from the concept of the present invention, more other equivalent embodiments may be included. It is possible for those skilled in the art to make various obvious changes, readjustments and substitutions without departing from the protection scope of the present invention.
