Referring to FIG. 1, the access control system includes a camera unit 110, an accessor information input unit 120, an access controller 130, a display unit 140, a server unit 150, and the like.

The camera unit 110 is installed at the doorway and transmits the video image of the image of the person to the access controller 130. Here, the camera unit 110 is to be implemented to shoot the image of the person at the point of time when the person enters the card or fingerprint to enter, that is, when the person information is input to the person information input unit 120 to be described later. desirable.

Accessor information input unit 120 is a role that receives the accessor information (card ID number, fingerprint) of the person who wants to request a permission to transmit to the access controller 130, for example, a number input unit, card reader, fingerprint reader, Iris recognizer.

At this time, in the present embodiment, the accessor information input from the accessor information input unit 120, information generated at the time when the accessor information is input, that is, the access time, the door that the accessor enters, the information on the access direction and the access status and the like Access information, including the implementation is implemented to be transmitted to the access controller 130. Accordingly, there is an advantage that it is possible to secure not only the accessor information, but also information such as access time, door, and access direction.

The access controller 130 receives the access image from the camera image 110 and the access information from the access information input unit 120, and processes the video image and access information of the access to the display unit 140. . And for this purpose, the access controller 130, as shown in Figure 1, comprises an accessor information storage unit 132, access authorization decision unit 134, access control unit 136 and the image processing unit 138 and the like. .

On the other hand, in the present embodiment, the access controller 130 may be provided with means for generating access information by the access information received from the access information input unit 120.

In this case, the information inserted into the video image may further include the accessor's access information and the accessor's personal information. Looking in more detail, after receiving the image image and the access information from the camera unit 110 and the accessor information input unit 120, the access information and accessor information storage unit 132 in a location that does not overlap the image image by a specific algorithm Personal information stored in the), but necessary information can be inserted invisible.

Therefore, since the image image, the access information, and the personal information are generated as one file, there is no need to manage the information separately, thereby simplifying file management.

Here, the location where the access information and the personal information are inserted is irrelevant to any location that does not overlap with the video image of the person.

The display 140 receives the processed information from the image processor 138 and outputs the processed information. In this case, the mixed image is outputted and displayed by a general CCTV monitor and a digital video record (DVR), and the access information and personal information are not displayed because they are hidden in a position not overlapping with the video image.

Therefore, access information and personal information of the accessor is not exposed to a specific person requesting a video image of a manager, a monitor, and an accessor who manages the CCTV, thereby keeping the security thoroughly.

2 is a view conceptually illustrating a screen in which a mixed image generated by processing by an image processing unit of an access controller is output to a display unit. Referring to FIG. You can see that the information and personal information is hidden to be inserted (access time, card ID number, name, door, access status is hidden). In other words, the information is inserted at the lower end A of the video image, but is not represented.

That is, the access controller 130 and the display unit 140 are integrated and operated so that the mixed image generated by the image processing unit 138 of the access controller 130 is displayed on the display unit 140, thereby visually recognizing only the image of the accessor. can do.

The server unit 150 receives and stores the processed information in the image processing unit 138, and extracts the characters of the access information and the personal information in the form of text from the processed and mixed image information (mixed image). At this time, the access information and personal information is extracted from the mixed image and stored separately from the image image. In particular, the extracted information is stored in the field or as searchable information. Accordingly, since the relationship information between the access information and the video image can be secured, it is possible to confirm the access information and the video image of the person afterwards.

3 is a conceptual diagram illustrating that characters of access information and personal information are extracted from a mixed image in the form of characters. Character information of the access information and personal information is extracted from the mixed image as shown in FIG. , Card ID number, name, door, access status are extracted).

Therefore, the administrator inputs a condition (for example, card ID number, name of the person, etc.) of the search to the general PC 220 connected to the server unit 150, the character information satisfying this from the server unit 150 By searching for, it is possible to quickly and accurately search (output) the corresponding text information or the video image corresponding to the text information.

In this embodiment, since the mixed image is separated into the video image of the accessor, the access information and the personal information only by a specific algorithm, even if the mixed image is provided to the other person, the other person cannot extract the access information and the personal information. Security can be maintained.
