Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the present invention provides a computer-based artificial intelligence recognition system, which includes an access control device 100, a region monitoring device 200, a region recognition device 300, an alarm prompt device 400, and a central server 500. The access control device 100 is installed at each entrance of a monitoring place to recognize access control identification information of an entering person and control opening and closing of the entrance.
As shown in fig. 2, the door access device 100 is mounted on a wall at a doorway, and includes a housing, and a display screen 130 and a camera 120 mounted on the housing, wherein a radio frequency card reader is mounted inside the housing, and a card reading area 110 corresponding to a mounting position of the radio frequency card reader is provided on the housing. The shell is also internally provided with a microcontroller and a memory, the memory is stored with pre-recorded radio frequency card information, and when a radio frequency card is placed in the card reading area 110, the radio frequency card reader reads the information in the radio frequency card and sends the information to the microcontroller. The microcontroller searches and judges whether the read radio frequency card information exists in the memory, if so, the microcontroller controls the display screen 130 to display prompt information that the identity authentication passes and controls the opening of the entrance. If not, the microcontroller controls the display screen 130 to display a prompt message that the authentication fails.
After the microcontroller determines that the authentication passes, the camera 120 is also controlled to acquire a status image of the user, where the status image includes facial information, dressing information, and the like of the user. After acquiring the status image, the microcontroller sends the status image to the area identification device 300.
The area recognition apparatus 300 is a computer device disposed in the monitored area, and is connected in communication with the door control apparatus 100, the area monitoring apparatus 200, the alarm prompting apparatus 400, and the central server 50. The access control system comprises a monitoring place, a plurality of monitoring areas, a plurality of area identification devices 300 and at least one area monitoring device 200, wherein the monitoring place is divided into the monitoring areas according to requirements of area, function, level and the like, each monitoring area corresponds to at least one access, each monitoring area is provided with one area identification device 300 and at least one area monitoring device 200, the access control device 100 sends state images to the area identification devices 300 in the corresponding monitoring areas, and the area identification devices 300 simultaneously send the state images to the central server 500.
In the above embodiment, only the validity of the radio frequency card held by the user needs to be verified, and since the data size of the radio frequency card information is small, only the access control device 100 needs to complete the authentication. In another embodiment, the access control device 100 collects the radio frequency card information and the state image at the same time, and sends the state image to the area identification device 300 for validity verification, the area identification device 300 obtains a result of whether the radio frequency card information is valid, and if the radio frequency card information is valid, the radio frequency card information held by the user corresponding to the state image is obtained. The access control device 100 determines whether the read radio frequency card information is consistent with the radio frequency card information fed back by the area identification device 300 under the condition that the radio frequency card is legal, and if so, confirms that the user passes the authentication.
After the user enters the monitoring area, the area monitoring apparatus 200 collects the image information of each user and transmits the image information to the area recognition apparatus 300. The region recognition apparatus 300 first searches the image information for a region matching the facial features, and if such a region exists, extracts an image in the region and performs face recognition. And if the result obtained by the primary face recognition is legal or unknown, the face image is sent to the central server 500 for secondary face recognition.
The user information stored in the area recognition device 300 is limited to the information of the users who frequently move in the corresponding monitoring area, so when the users acquire the image information in the monitoring area which frequently moves, the area recognition device 300 obtains a legal result in the initial face recognition, thus shortening the information processing time and accelerating the recognition response speed. When the user is in the monitoring area which does not move frequently, the validity of the user identity cannot be determined because the information of the user is not stored in the area recognition device 300, and then the central server 500 needs to perform secondary face recognition.
The central server 500 comprises a processor and a memory in which information of all registered users in the monitoring location is stored. After receiving the face image sent by the area recognition device 300, the processor extracts the features in the face image, matches the features of the face image in the user information stored in the memory, and feeds back an identification result with a legal identity to the area recognition device 300 if the matching is successful.
Although performing the secondary recognition requires a network connection with the center server 500, it causes a long information processing time. However, the area recognition apparatus 300 or the central server 500 is located in the local area network, so that the influence on the information processing time is not great, and the accuracy of identity recognition is greatly improved.
If the image information does not have the area which is in accordance with the facial features, the area recognition device 300 extracts the dressing information in the image information, then matches the dressing information in the stored state image, and if the matching is successful, obtains the recognition result with the legal identity. If the matching fails, the area recognition device 300 transmits the dressing information to the central server 500, and the processor performs secondary dressing recognition. If the secondary dressing identification result is that the identity is legal, the processor feeds back an identification result with a legal identity to the area identification device 300.
Since the user may change the worn clothes in the monitoring place, the dressing recognition cannot guarantee 100% correct recognition. At this time, if the dressing recognition result is that the identity is illegal, the region recognition device 300 extracts the gait information in the image information again and then performs gait recognition. If the identity validity is unknown, the area identification device 300 sends the gait information to the central server 500. The central server 500 performs secondary gait recognition, and feeds back a recognition result of which the identity is legal to the area recognition device 300 if the result of the secondary gait recognition is that the identity is legal.
If the result of the face recognition or the gait recognition is that the identity is illegal, the area recognition device 300 sends alarm prompting information to the alarm prompting device 400.
As shown in fig. 3 and 4, the alarm prompting device 400 includes an audible and visual alarm 420 and an intercom alarm 410, and the audible and visual alarm 420 is mounted on the area monitoring device 200. The area monitoring apparatus 200 includes a body 210 and a mounting block 220, the mounting block 220 is fixed on a wall, and the body 210 is mounted on the mounting block 220. Audible-visual annunciator 420 is installed on main part 420 for send audible-visual annunciation information, warn potential illegal personnel.
The talkback alarm 410 has a wireless talkback function and is used by security personnel at ordinary times. When the area recognition device 300 confirms that the person with the illegal identity exists, alarm prompt information is sent to the talkback alarm 410, wherein the alarm prompt information includes information such as a monitoring area where the person with the illegal identity exists.
In this embodiment, after the audible and visual alarm 420 gives an audible and visual alarm, the user may display information indicating the legitimate identity of the user, so as to eliminate the misjudgment of the area recognition device 300. The information displayed by the user includes a specific gesture or a facial image, the area monitoring device 200 collects the information and sends the information to the area recognition device 300, the area recognition device 300 recognizes the information displayed by the user, and if the information is legal, the area recognition device sends a prompt message for canceling the alarm to the alarm prompting device 400.
If the user does not display the information within the set time, or the displayed information identification result is still illegal, the area identification device 300 sends an alarm prompt message to the talkback alarm 410.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
