Although the screening is greatly improved by performing the identity verification and the screening list check using the face matching technology in the automatic screening system, there are the following problems in the system currently being studied.
In the automatic examination, the face image is read from the IC chip of the passport and the person is verified using the face matching technique.
Although the examination list is checked using face images at the time of automatic examination, if there are tens of thousands of registered examination lists, the check takes a long time.
Since the processing time per case is longer than that for human screening, the waiting time for screening increases, which may lead to service degradation. In addition, in order to eliminate the waiting time, it is necessary to increase the number of examination booths and the number of examiners, and there are significant space and cost issues.

  Accordingly, an object of the present invention is to provide an admission management system and an admission management method capable of significantly reducing the processing time per case as compared with human system examination.

  In the admission management system according to the present invention, at least a face image of a person recorded on a personal authentication medium possessed by a person who moves toward an admission target area desired to enter is displayed in the admission target area. Reading means that reads before reaching, image acquisition means that is provided in the vicinity of the entrance target area and acquires an image including at least the face of a person moving toward the entrance target area, and read by the reading means A first verification unit that determines whether or not a predetermined relationship is established between the two facial images by comparing the face image with the facial image acquired by the image acquisition unit; and the first verification unit Gate control means for controlling opening and closing of an entrance gate device provided in the entrance target area according to the determination result.

  In addition, the admission management method of the present invention is such that at least a person's moving face image recorded on a personal authentication medium possessed by a person who moves toward an admission target area desired to enter is said admission target. A reading step for reading before reaching the area, an image acquisition step for acquiring an image including at least the face of a person moving toward the entrance target area in the vicinity of the entrance target area, and the reading step. A first collation step for collating the face image with the face image acquired in the image acquisition step to determine whether or not a predetermined relationship is established between the two face images; and the first collation step And a gate control step for controlling opening and closing of an entrance gate device provided in the entrance target area according to the determination result.

  According to the present invention, the personal authentication medium is read before the target person reaches the entrance target area, and the face image is acquired and collated while the person is moving toward the entrance target area. Alternatively, a face image is acquired while the target person is moving toward the entrance target area, and when the person arrives at the entrance target area, the personal authentication medium is read and verified. Thus, it is possible to provide an admission management system and an admission management method that can significantly reduce the processing time compared to human system examination, thereby reducing examination waiting time and improving services.

Embodiments of the present invention will be described below with reference to the drawings.
In addition, in the following description, application to the immigration examination at an airport will be described as a representative example as the entrance management to the entrance target area.
