Problems solved by technology

[0004] Although smart terminals are currently equipped with high-definition cameras, people still cannot take pictures on their mobile phones and other smart terminals that are convincing and acceptable to the certification department.
Because there are detailed government public security industry standards for photos used in legal documents, such as: technical standards for digital photos of second-generation resident ID cards: "GA 461-2004 Technical Requirements for Digital Photos for Resident ID Cards"; digital photo technology for motor vehicle driver's licenses Standard: "GA482-2012 Motor Vehicle Driver's License of the People's Republic of China"; technical standard for digital photos of entry-exit documents: "GA / T 1180-2014 Technical Requirements for Digital Photos of Entry-Exit Documents", etc. These standards require many and detailed items. It is generally difficult to fully understand these standards, and it is even more difficult to implement them. The shooting effect varies from person to person, and the quality of the photos is uneven. It is impossible to ensure that the photos taken meet the standard requirements of ID photos.
Therefore, general shooting software cannot ensure that the photos taken meet the standard requirements for photos used in the production of legal documents

Embodiment 1

[0110] The card camera of this embodiment is an APP (Application, application program) installed on an intelligent terminal, which is connected to the Internet. The original image of the license, the original image of the license refers to the image data that is captured by the user in real time through the license camera, and the useful area of ​​the image is cropped according to the license standard, and the image information such as color, brightness, background, and biological characteristics of the person has not been processed in any way. During the shooting process, the ID camera automatically configures the best shooting parameters, automatically detects and reminds the user to adjust to the best shooting state, and automatically crops after shooting, so that the original image of the ID card can be taken in accordance with the production of the ID card; then, the original image of the ID card is cut out. Image replacement background, automatic shooting quality governme...

Embodiment 2

[0150] like Figure 6 As shown, the certificate photographing method of this embodiment is realized based on the certificate camera of the above-mentioned embodiment 1, including the following steps:

[0151] S1. Detect whether the shooting parameters such as brightness, exposure, and white balance of the smart terminal camera meet the requirements for taking photos of documents. If not, configure the shooting parameters according to the preset parameters, such as auto focus, auto exposure, auto light supplement, White balance and other configurations;

[0152] S2. Obtain the preview frame image from the camera of the smart terminal at a certain time interval (the time interval is set by the developer), and during the framing stage, the card camera extracts the portrait feature data of the preview frame image; wherein, the preview frame image is extracted The portrait feature data; wherein, the portrait feature data includes face profile, torso profile, portrait profile, eyes...

Embodiment 3

[0210] like Figure 7 As shown, the card camera system of this embodiment includes a card camera, a card camera access server and a card cloud storage terminal, and accesses an associated system: an intelligent cloud processing system for ID photos, wherein the card camera is connected to the server, the card cloud The storage terminal and the ID photo intelligent cloud processing system are both located in the same private intranet. The ID camera access server and the ID photo cloud storage end are connected to the Internet through the firewall, which guarantees the security of the ID photo intelligent cloud processing system to a certain extent. As described in Embodiment 1, the witness camera is an APP installed on a smart terminal, and the smart terminal is also connected to the Internet.

[0211] The ID camera access server is mainly responsible for the access of the ID camera to the ID photo intelligent cloud processing system. It detects the authorization legality of th...

Abstract

The invention discloses a certificate picture camera and a certificate picture photographing method. The certificate picture camera comprises a parameter configuration module, a data obtaining module, a detection reminding module, an intelligent cutting module and a photographing quality grading module. The certificate picture photographing method comprises the following steps: detecting whether photographing parameters of an intelligent terminal camera satisfy certificate picture photographing requirements or not, and if not, configuring the photographing parameters; obtaining sensor data of an intelligent terminal, portrait characteristic data, luminance data, definition data and chromaticity distortion data of a preview frame image, judging whether relevant standard requirements of a legal certificate picture are satisfied or not, and if so, obtaining original image data after pressing a photographing button; cutting the original image data so as to obtain a standard-sized original picture of the certificate picture; grading the shooting quality of the original picture of the certificate picture, and giving a suggestion according to a comprehensive grading result. According to the invention, users can photograph the certificate picture satisfying government and public security industrial standard requirements in a self-service manner.

Description

technical field [0001] The invention relates to a certificate camera and a certificate photographing method, and belongs to the technical field of certificate photo photographing and processing. Background technique [0002] ID photos refer to photos used in the production of legal documents such as ID cards, passports, Hong Kong permits, Macau permits, Taiwan permits, visas for going abroad, residence permits, social security cards, etc. These photos often have many shooting skills and shooting quality requirements. Judging from the current situation, people generally can only go to a special photo studio or professional organization (such as a security company) to take pictures, and only after professional personnel perform photo cropping and background replacement can they get a certificate that meets the relevant technical requirements. Taking photos, the whole process takes a lot of time and brings a lot of inconvenience to people taking photos of documents. [0003] B...
