Fig. 1 is a flowchart of a method for quickly photographing a certificate photo according to the present invention. The method for quickly shooting the certificate photo is used in self-service certificate handling equipment. The self-service certificate handling equipment can be equipment for handling identity cards and can also be equipment for handling certificates such as residence permit, driving permit, port and Macau pass and the like. The method for quickly shooting the certificate photo comprises the following steps:

In step S101, the self-service certificate transaction device may be a device for handling an identity card, or a device for handling certificates such as a residence permit, a driver' S license, a port and australian pass. In this embodiment, the device is used for handling identity cards. Self-service certificate handling equipment is provided with high definition digtal camera in order to gather target user's image, is provided with fingerprint identification module in order to gather target user's fingerprint, is provided with the touch-control display screen and supplies the user to carry out information input. When continuous shooting is performed, it is generally performed to detect that the target user enters the preset shooting area, for example, continuous shooting is performed within five seconds, and 10 pictures are shot per second.
In step S102, the matching degree may be calculated by using a pre-trained neural network model, or of course, other methods may also be used, for example, a partitioned matching algorithm may be used to calculate whether each region matches the criterion, and then the overall matching degree is calculated.
In step S103, when the auxiliary photo is used to repair the main photo, the region meeting the standard in the auxiliary photo can be scratched to repair the corresponding region not meeting the standard of the main photo, and operations such as scaling and cutting are required during repairing, or of course, an image fusion algorithm can be used to repair.

For example, the plurality of first regions may include a shoulder region, a mouth region, an eye region, a hair region, and the like, but is not limited thereto, and the regions are divided mainly according to the corresponding identification photo standard. When each first region of each initial photo is matched with the corresponding region of the standard certificate photo, a pre-trained neural network model can be adopted, and a matching algorithm in the prior art can also be adopted for realizing the matching. For example, taking a picture requires opening the eyes, and if you close the eyes, the eye area does not meet the corresponding criteria. When the matching degree of each initial photo is calculated, the matching degree of each initial photo can be obtained according to the following formula P = a1/a 2; wherein, P is the matching degree, a1 is the number of the first regions meeting the criterion in the initial photo, and a2 is the total number of the first regions in the initial photo.
