DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Referring to the accompanying drawings, the same or corresponding components are denoted by the same reference numerals, do.

1 is a view showing an elevator operation system using a surveillance camera according to an embodiment of the present invention.

Referring to FIG. 1, an elevator operating system using a surveillance camera includes a plurality of surveillance cameras 100: 101 and 103, a central control unit 200, and a plurality of elevators 300: 301 and 303.

The surveillance camera 100 is installed inside the elevator 300 to capture video and audio information inside the elevator 300.

The central control unit 200 outputs a control signal for operating the elevator 300 based on the audio and video signals captured by the surveillance camera 100. The output of the control signal for operating the elevator 300 of the central control unit 200 will be described with reference to FIG.

FIG. 2 is a detailed configuration diagram of an elevator operation system using the surveillance camera shown in FIG. 1.

Referring to FIG. 2, the video / audio input unit 110 provided in the surveillance camera 100, the elevator open / close detection unit 210 provided in the central control unit 200, the target counter unit 220, and the target confirmation unit 230, a gesture / voice recognition unit 240, a storage unit 250, a controller 260, and an elevator operating unit 310 provided in the elevator 300.

The video / audio input unit 110 acquires a video and audio signal inside the elevator 300. The video / audio input unit 110 acquires video and audio information when the target enters and exits under the control of the controller 260 in connection with the target entry and exit through the elevator door opening / closing detection, and the like, and the information when the elevator 300 is not used. Abort the acquisition. In the case of the elevator 300, since there is almost no time such as day or midnight, even when using the recording equipment of the same specification, it is possible to efficiently operate the system by reducing the recording time and storage capacity. In addition, even if the video and audio information is not used, it is possible to determine whether to record according to whether the elevator 300 is operated by receiving a signal from the elevator operating unit 310.

The elevator opening / closing detection unit 210 detects whether the elevator 300 is open / closed from an input video and audio signal. The most important event in the elevator 300 is whether or not the object to be used. It is possible to check whether the elevator 300 is opened / closed by receiving information on the current state from the elevator operating unit 310. In addition, it is possible to check whether the door is opened or closed through the sound when the door is opened or closed by receiving a voice signal. It is possible to check the opening / closing by analyzing the image information.

FIG. 3 is a diagram for analyzing whether the elevator 300 is opened / closed by analyzing image information. After finding a case where a sudden change in brightness occurs in the image being photographed as shown in FIG. 3A, when the area becomes wider, the door of the elevator 300 opens, and when the area widens and decreases, the door closes. You can see that. In addition, movement occurs when opening / closing the elevator 300. Therefore, after setting the door area of the elevator 300, it may be determined whether the door is opened / closed when a sudden motion occurs in the area. 3B is a method of estimating motion by subtracting the foreground when the current image is input after the foreground / background separation is performed. As shown in Figure 3b, it can be seen that a lot of motion occurs in the part of the door opening and closing.

The object counter 220 counts the number of objects passing through a specific line in the elevator 300 from the input image. You can also check the entrance by setting the direction.

The object identifying unit 230 confirms a user inside the elevator 300, and may use a method such as a face recognition, an iris recognition, or an object having an RFID tag and a fingerprint recognition. Such information may be compared with existing data stored in the storage 250 to identify a target.

The gesture / speech recognition unit 240 recognizes a gesture or a voice of a person who boards the elevator 300. When there is an object inside the elevator 300, the elevator 300 is basically operated by using a button. In this system, since the surveillance camera 100 that can receive the video and audio information is installed, it can be used to operate the elevator 300. First, an object request confirmation step is needed to determine whether the object is to operate a button or through a hand signal or an audio signal. In the case of gesture recognition, when a target expresses a specific number above the head, the elevator 300 can be operated by automatically pressing a button moving to a corresponding floor. Alternatively, when the elevator 300 breaks down, a specific operation may be determined to notify the elevator operating unit 310 of the failure and generate an alarm. In the case of using a voice signal, for example, if a user says "XX floor", the user may recognize the button and automatically press a button of a specific floor. By fusing gestures and voice signals, it is possible to reduce false alarms in exceptional situations. For example, the subject currently gives a signal that he or she is going to speak a certain word first, and then speaks that particular word. A plurality of subjects may select priorities when using the elevator 300. For example, you can assign buttons in order of first to perform a certain action or to say a certain word first.

The storage unit 250 records and stores a variety of information for identifying a target, and also records a video signal and an audio signal input through the video / audio input unit 110, and by a control signal of the controller 260. You can stop recording.

The controller 260 generates a control signal for manipulating the elevator 300 based on the video / audio signal processed by other components, and outputs the control signal to the elevator operating unit 310 to output the control signal to the elevator 300. To be manipulated.

The controller 260 may store the elevator 300 usage record, and then set the optimum operation line of the elevator 300 for each time. For example, at 2:00 pm, a control signal capable of manipulating a certain floor or the like may be generated. You may be waiting for the floor you use often. In addition, since the start / leave often around 8 o'clock in the morning, from 7 to 9 o'clock in the evening, it is possible to generate a control signal to speed up the elevator 300, and to generate a control signal to slow down at other times. . This saves energy and increases user convenience.

In the case of a conventional elevator, when a large number of subjects were burned based on weight, a full sound was confirmed to generate a warning sound. However, the position of the person in the elevator 300 may be affected or may not be inconsistent with the actual number of people. However, since there is user number information, the controller 260 may operate the elevator 300 by determining the actual number of occupants to determine whether it is full.

In case of the existing elevator, the door is automatically closed at a certain time, or when the user presses a button, the door is closed or opened. If there are many targets for use, there is a shortage of time or if the targets for use are small, the waiting time is long. However, since it is possible to check an object passing through a specific line, the controller 260 generates a control signal that automatically closes the door when there is no person passing through the line for a specific time, reducing the user's waiting time, and operating a button. It is possible to minimize the energy consumption by not using the close button.

After entering the building in which the elevator 300 is installed or storing the information for pre-recognition only for those who frequently enter and exit, the information detected by the face recognition is zoomed in to obtain the information so that the current boarding target is stored. Check if it matches When the zoomed-in face and the stored information coincide with each other, since the information about the object is known, the controller 260 may generate a control signal to automatically operate the elevator 300 without button manipulation. Before providing such a service, for example, "Welcome ○○. Would you like to go home" or "Would you like to move to floor ○○?" To check whether the user is currently recognized and wants automatic operation. If the user sends a hand signal capable of gesture recognition or says a specific word such as "yes" or "yes", the user generates a control signal for automatically operating the elevator 300. Or you can go somewhere other than your own home, so wait when there is no signal that you want to use it. If you move to the target house to operate the elevator 300, it may be installed with a system that notifies each household in advance that XX is coming. If facial recognition fails, "What's your name?" And the answer is recognized by voice recognition technology, it can provide the same service as the case of successful face recognition. If the object of use cannot be recognized even by the foregoing methods, the controller 260 determines the current object of use as an unregistered person, generates a control signal for recording a zoomed-in face, notifies the security guard or performs a face tracking function. By using it to generate a control signal that records and records on which floor the current boarding target is displaced, it is possible to respond quickly to an accident. In addition, there may be an object for which a general button operation is desired.

Therefore, when the object of use in the elevator 300 moves near the elevator 300 operation button, a control signal with exception processing may be generated to terminate the automatic operation and to allow manual operation.

In addition, the controller 260 may prevent the jamming accident by generating a control signal for opening the door of the elevator 300 when a person passing through a specific line is confirmed while the door of the elevator 300 is closed.

The controller 260 knows the number of objects to be used for the elevator, and the user should be currently in the elevator 300. If the elevator 300 has not moved for a certain time, the control unit 260 may provide a control signal indicating that the elevator 300 has failed. Can be generated.

The controller 260 generates a control signal for performing a power saving mode when there is no elevator use target, thereby saving energy by minimizing unnecessary power.

In addition, the controller 260 may turn off recording of the video and audio signals of the surveillance camera 100 when there is no object to use the elevator 300 and record only when necessary, thereby efficiently managing the recording time and storage space. .

Furthermore, in the past, a method of authenticating an object by passing through a gate has been most widely used in the case of a company, but the surveillance camera 100 installed in the elevator 300 may be used or the object may be recognized in the elevator 300. Therefore, the system can be configured to enable time and attendance processing such as entrance management.

In addition, the existing elevators were available on all floors with button operation regardless of the object of use. However, due to the recognition of the use target, a security incident or the like can be prevented by limiting the floors available for each use target. In addition, even if several targets are used, an alarm or a record can be taken if the floor is not available.
