Embodiment 1

[0032] An embodiment of the present invention provides a safety examination system for automatic facial recognition, which is composed of hardware equipment and supporting software.

[0033] In the safety examination system of automatic facial recognition, such as figure 1 As shown, it includes a plurality of examination rooms 1, and each examination room 1 is equipped with one or more examination stations 2, and each examination station 2 is equipped with a monitoring camera 4 and an examination device 3, and the monitoring camera 4 is used to regularly photograph the examinee's face to obtain the facial feature data of the examinee, and transmit the facial feature data to the cloud server 5, and the examination device is used to display the examination questions to the examinee, obtain the answer result of the examinee, and transmit the answer result to the The cloud server.

[0034] The monitoring camera 4 and the examination device 3 on each examination station are all co...

Embodiment 2

[0075] like Image 6 As shown, the embodiment of the present invention uses the automatic facial recognition security examination system shown in Embodiment 1, and specifically describes the usage of the automatic facial recognition security examination system.

[0076] The safety examination system of automatic facial recognition in the embodiment of the present invention can be used to carry out two kinds of examination modes of conventional examination 7 and dynamic examination 8, and described routine examination 7 is a kind of unified, concentrated examination mode, and described dynamic examination 8 is a kind of examination mode. Customized, remote exam mode. The regular exams include entrance exams 71 and relevant professional final exams 72 . The dynamic test 8 includes the test 81 after the purchase of hazardous chemicals / special equipment before use, the test 82 after the safety inspection to find out the problems existing in the inspection, and the test 83 for rel...

Embodiment 3

[0103] In the above two embodiments, it is necessary to monitor the examinee or identify the information of the examinee based on facial recognition. In order to improve the recognition rate and the recognition speed, the embodiment of the present invention provides a method for identifying the examinee. The method is as follows: Figure 12 shown, including:

[0104] Step 1: Perform preprocessing on the preset photo, locate the facial organs in the preset photo, and construct a feature vector corresponding to the preset photo according to the positioning result, and the feature vector is a known feature vector.

[0105] Step 2: Obtain the image taken by the surveillance camera, preprocess the image, locate the facial organs, and construct the feature vector to be matched.

[0106] Step 3: Perform similarity matching between the known feature vector and the feature vector to be matched.

[0107] Step 4: If the matching value is higher than the recognition threshold, the matchi...

Abstract

The invention provides an automatic face identification safety examination system. The system comprises a monitoring camera and a test device, wherein the monitoring camera and the test device are both in communication connection with a cloud server, the monitoring camera is used for shooting faces of students and acquiring face characteristic data of the students in a fixed time and transmittingthe face characteristic data to the cloud server, the face characteristic data corresponds to the students in a one-to-one correspondence, and the cloud server is used for searching examinee identifiers according to the face characteristic data information, automatically acquiring question keywords according to the examinee identifiers and constructing test questions issued to the students. The system is advantaged in that a problem that the current laboratory safety test can not achieve adequate room conditions, personalization and differentiation in the prior art is solved, targeted and morespecific safety exam training can be organized, and problems of poor monitoring of online security exams, easily-generated surrogate exam-taking phenomena, frauds and other issues are solved.

Description

technical field [0001] The invention relates to the system field of laboratory safety examinations conducted by colleges and universities or scientific research institutes, and more specifically relates to a safety examination system for automatic face recognition. Background technique [0002] The laboratory is an important base for scientific and technological innovation and personnel training in universities or scientific research institutes. However, laboratory safety accidents have occurred frequently, causing many personal and property losses, and seriously endangering social security and stability. Therefore, colleges and universities and scientific research institutes pay more and more attention to laboratory safety education and management. Many domestic colleges and universities offer safety training and guidance, and conduct safety knowledge assessments for freshmen and new teachers. However, the content of safety exams is often outdated and stereotyped; the form i...
