Further, in order to facilitate the examinee to inquire about the related examination information, corresponding target information items are obtained according to the type of the matching information, for example, the matching information comprises mathematic examination category information, chinese examination category information and English examination category information, wherein the target information items corresponding to the mathematic examination category information comprise examination time, examination place, examination seat and other examination information of the mathematic subjects.
In order to reduce the occurrence of the above situations, it is further determined whether the information content corresponding to the obtained target information item meets the preset input information content, where the preset input information content refers to the information content corresponding to when the matching information is input into the database in advance. And if the information content corresponding to the target information item does not accord with the preset input information content, acquiring the corrected information content corresponding to the target information item according to the preset input information content.
For example, if the target information item is a mathematics examination category information, the system monitors that the displayed information content is examination time corresponding to a Chinese examination subject, an English examination subject corresponding to an examination place and an examination seat corresponding to a mathematics examination subject, then it can be determined that the information content corresponding to the target information item does not accord with the preset input information content, and the system further searches the corresponding preset input information content in the matching database according to the mathematics examination category information, acquires the examination time corresponding to the mathematics examination subject, the examination place corresponding to the mathematics examination subject and generates corresponding correction information content, and corrects the information content displayed by the mathematics examination category information according to the correction information content.
If the information content corresponding to the target information item accords with the preset input information content, the information content in the target information item is indicated to have no abnormal error, a corresponding information fusion table is further generated according to the information content, the information fusion table is a fusion table formed by indicating all examination information corresponding to the examinee, printing of the information content required in the information fusion table can be selected according to actual requirements of the examinee, and examination information inquiry table printing or examination label printing can be selected.
For example, the information fusion table includes the information content of mathematics, chinese and English examination subjects related to examination of the examinee A, the first examination of the examinee A is the mathematic subject, and in order to conveniently carry the examinee A, the information content of the mathematic examination subjects is selected from the information fusion table for printing the mathematic examination information inquiry table.
For another example, when the examinee a needs to print the examination label corresponding to the mathematical examination subject at the approach time of the mathematical examination subject, the examinee a selects the information content of the mathematical examination subject from the information fusion table to print the examination label.
According to the label printer printing method, the face image of the examinee is acquired and identified, the corresponding identification result is obtained, the identity information of the examinee is conveniently confirmed according to the identification result, if the face identification result is identification success, the identity verification of the examinee is indicated to pass, the matching information corresponding to the examination can be further acquired, the security of the acquisition of the information of the examinee is further improved, then the corresponding target information item to be inquired or printed is acquired according to the type of the matching information, whether the information content corresponding to the target information item accords with the preset input information content which is input in advance by a system or not is judged, whether the information content is wrong or not is judged, if the information content does not accord with the preset input information content, the correction information content corresponding to the target information item is acquired according to the preset input information content, the correction information content is corrected according to the preset input information content, the misleading condition caused by the information content error is further reduced, if the information content accords with the information fusion table which the examinee needs to be printed is generated according to the information content, the corresponding examination information query table or the label examination is further printed according to the actual requirements of the examinee, and the functions such as identity authentication, information query and information examination are added at the same time when the label printing work is completed, and the corresponding adaptation degree of the label printer in a student scene is improved.
In one implementation manner of this embodiment, as shown in fig. 2, step S101 is to acquire and identify a face image of a subject, and generating a corresponding face recognition result includes the following steps:
s201, acquiring face region coordinates corresponding to a face image of a student;
s202, calculating face region coordinates according to a face feature extraction algorithm, and generating corresponding face feature vectors;
s203, combining the face feature vector and a preset face feature vector to generate a corresponding similarity value;
s204, if the similarity value is larger than a preset similarity threshold value, outputting a face recognition result to be successful recognition;
s205, if the similarity value is smaller than or equal to a preset similarity threshold value, outputting a face recognition result to be recognition failure.
In practical application, in order to improve the security of the acquisition of examination information of an examinee, the identity information of the current examinee is identified and verified before the examination information related to the query is acquired. And acquiring the face image of the current examinee through a face recognition camera arranged on the label printer.
Specifically, the label printer database stores backup information of all photos of the examinee, the photo information of the current examinee is processed independently and enters a face detection network, face region coordinates are obtained through the network, and the face region is cut out from the photos according to the coordinates, so that a picture with only faces is obtained.
Further, the obtained face image is subjected to a face feature extraction algorithm to obtain a corresponding face feature vector, the corresponding face feature vector is stored in a label printer, feature similarity calculation is carried out on the obtained face feature vector and the face feature vector stored in the printer, the feature with the highest corresponding similarity is obtained, the similarity value is compared with a preset similarity threshold value, if the similarity value is larger than the preset similarity threshold value, the fact that the current examinee is the examinee corresponding to the feature with the highest similarity in the label printer, namely the output face recognition result is successful recognition, otherwise, the fact that the current examinee information is not matched is the output face recognition result is failed recognition.
According to the label printer printing method, the corresponding similarity value is obtained by combining the corresponding face feature vector in the face image of the examinee and the preset face feature vector, and the size relation between the similarity value and the preset similarity threshold value is further judged, so that the accuracy of identity verification of the examinee is improved.
In one implementation manner of the present embodiment, as shown in fig. 3, step S204, that is, if the similarity value is greater than the preset similarity threshold, outputs the face recognition result as the recognition success includes the following steps:
S301, if the similarity value is larger than a preset similarity threshold value, generating a corresponding first facial dynamic characteristic acquisition instruction;
s302, acquiring first facial dynamic characteristics corresponding to an object to be identified according to a first facial dynamic characteristic acquisition instruction;
s303, if the first facial dynamic characteristics do not accord with the preset facial dynamic characteristic standard, generating a facial abnormality recognition prompt.
In practical application, because the phenomenon that some improper purpose examinees use other tools such as face photos or videos of the examinees and 3D face models to deceptively attack the face recognition system exists in reality, in order to reduce the occurrence of the situations, on the basis that the similarity value is larger than a preset similarity threshold value, corresponding first facial dynamic feature acquisition instructions are further generated, according to the first facial dynamic feature acquisition instructions, first facial dynamic features corresponding to an object to be identified are acquired, the object to be identified is the examinee needing to acquire examination information at present, the first facial dynamic feature acquisition instructions comprise instructions for indicating the object to be identified to make corresponding facial dynamic, and the object to be identified can make corresponding facial actions according to the indication information of the preset facial dynamic feature acquisition instructions.
Further, if the first facial dynamic characteristics of the current examinee do not accord with the preset facial dynamic characteristic standard, the face of the current examinee is a non-living body, and a corresponding face abnormality recognition prompt is generated immediately to prompt related staff. The preset facial dynamic characteristic standard refers to facial dynamic characteristic information which is backed up by an examinee when the examinee inputs identity verification information, and facial actions can be made on site to be compared and confirmed with the preset facial dynamic characteristic standard when the examinee acquires relevant examination information, so that the identity verification of the examinee is enhanced, and the acquisition safety of the examinee examination information is ensured.
For example, the preset facial dynamic feature standard is that the mouth is opened and closed for 3 times, the system acquires the dynamic image of the face of the current object to be identified in a reasonable time through a common color camera according to the first facial dynamic feature acquisition instruction, analyzes the dynamic image to acquire the first facial dynamic feature of the face of the object to be identified, the first facial dynamic feature is the number of times of opening and closing actions of the mouth of the object to be identified, the system counts the number of times of opening and closing actions of the mouth of the object to be identified in real time, if the number of times of opening and closing actions of the mouth obtained by counting is equal to 3 times, the system judges that the first facial dynamic feature of the object to be identified accords with the corresponding preset facial dynamic feature standard, and then the system enters the next face identification detection.
For another example, if the number of times of the opening and closing actions of the mouth is counted and obtained is not equal to 3 times, it can be determined that the dynamic characteristics of the first face of the object to be identified do not meet the corresponding preset facial dynamic characteristic standard, and the system immediately generates facial abnormality recognition prompt information to prompt the relevant face recognition detection staff.
According to the label printer printing method provided by the embodiment, whether the first facial dynamic characteristics of the current examinee meet the preset facial dynamic characteristic standard set by the system is further judged on the basis that the similarity value is larger than the preset similarity threshold value, so that the occurrence of the condition that the illegal examinee uses images or video images to attack and cheat the face recognition system is reduced, and the security of examinee examination information acquisition is improved.
In one implementation manner of this embodiment, as shown in fig. 4, in step S302, that is, according to the first facial dynamic feature acquisition instruction, the following steps are further included after the first facial dynamic feature corresponding to the object to be identified is acquired:
s401, if the first facial dynamic characteristics meet the preset facial dynamic characteristic standard, acquiring authentication identity information of an object to be identified;
s402, acquiring and generating a corresponding second facial dynamic feature acquisition instruction according to the authentication identity information and the corresponding historical facial dynamic feature;
S403, acquiring second facial dynamic characteristics of the object to be identified according to a second facial dynamic characteristic acquisition instruction;
s404, judging whether the second facial dynamic characteristics accord with the historical facial dynamic characteristics;
s405, if the second facial dynamic characteristics do not accord with the historical facial dynamic characteristics, generating a facial abnormality recognition prompt.
In practical application, in order to further improve the security of the object to be identified, i.e. the current identity authentication of the examinee, further set the backup facial dynamic feature corresponding to the examinee after the system real-name authentication, i.e. the historical facial dynamic feature in step S402, where the backup facial dynamic feature may be recorded after the examinee performs the system real-name authentication.
On the basis that the first facial dynamic characteristics meet the preset facial dynamic characteristic standard, the next step of human face living body detection of the system is performed, firstly, authentication identity information of an object to be identified is obtained, the authentication identity information is identity record information corresponding to personnel after real-name authentication of the system, and the human face information of the object to be identified can be shot and collected through a face recognition camera.
