Problems solved by technology

[0006] The items required by these standards are numerous and detailed. It is generally difficult for people to fully understand these standards, and it is even more difficult to implement them. The shooting effects vary from person to person, and the quality of photos varies.
However, at present, only professional personnel check the quality of the pictures manually. There is no software on the market that can automatically complete the quality testing of these photos. Does the photo that comes out meet the implementation standards for ID photos?

Embodiment 1

[0112] The ID camera is an APP (Application, application program) installed on the smart terminal. It can have an Android version and an iOS version. The image data obtained by real-time shooting, 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 people has not been processed in any way.

[0113] The ID camera in this embodiment is aimed at the ID photos that have been taken and imaged, and can perform quality inspection on the ID photos. It mainly formulates various scoring dimensions according to the government public security industry standards, and establishes standard databases for different types of ID photos. Compare the ID photo data information with the data in the database, check and evaluate whether it meets the requirements item by item, and calculate the total quality score based on the test results. When the score of the total quality score...

Embodiment 2

[0247] Such as image 3 As shown, the present embodiment provides a shooting quality detection method, which is aimed at the shooting quality detection of the ID photo that is imaged but does not replace the background. It is applied to the ID camera and includes the following steps:

[0248] S1. Obtain file attribute information, portrait feature information, background information, brightness information, chromaticity information, and clarity information according to the captured and imaged ID photos, specifically including:

[0249] S101. Acquire the file attribute information of the ID photo; wherein, the file attribute information includes shooting time, color digits, file suffix, file capacity, and image pixels;

[0250] S102. Obtain portrait feature information of the ID photo; wherein, the portrait feature information includes eye, nose, ear, mouth, face outline, torso outline, portrait outline, head and chin feature data;

[0251] S103, convert the ID photo into a La...

Embodiment 3

[0274] The photographing quality detection method of this embodiment is aimed at the photographing quality detection of the certificate photo which is photographed and replaced with a standard background. The difference between it and Embodiment 2 is that:

[0275] S103. Using the edge detection technology to detect the outline of the portrait in the ID photo, and obtaining background information other than the outline of the portrait in the ID photo;

[0276] S206. Determine whether the acquired background information meets the requirements of the corresponding certificate photo.

[0277] In summary, the ID camera and method of the present invention formulate various scoring dimensions according to the government public security industry standards, and establish a standard database of different types of ID photos. One quality inspection to ensure that the ID photos that pass the inspection can meet the relevant standards for ID photos.

Abstract

The invention discloses an identification camera capable of detecting photographing quality and a photographing quality detecting method. The identification camera comprises an information acquiring module, a quality detecting module, a scoring module, a quality score computing module, and a photography suggesting module. The method comprises steps of: acquiring the file attribute information, the portrait characteristic information, the background information, the brightness information, the chrominance information, and the sharpness information of an identification photo; detecting the quality of scoring dimensions one by one according to the acquired file attribute information, the portrait characteristic information, the background information, the brightness information, the chrominance information, and the sharpness information; scoring the quality detection results of the scoring dimensions in order to obtain the scores of the scoring dimensions; according to the scores of the scoring dimensions and the weights of the scores, computing the total quality score of the identification photo; and according to the total quality score of the identification photo, giving a professional photography suggestion. The identification camera may guarantee that the identification photos passing the detection comply with a standard requirement correlative to the identification photos.
