  The monitoring processing device 100 includes a monitoring processing unit 110, a visitor image data storage unit 120 (described later, FIG. 3), a visitor affiliation information storage unit 130 (described later, FIG. 4), and a monitoring information storage unit 140 (described later). 5), a monitoring result storage unit 150 (described later, FIG. 6), and a warning determination information storage unit 160 (described later, FIG. 7).

  First, when a visitor enters the data center, the visitor performs a predetermined entry procedure at the reception of the data center. In the admission procedure, the reception terminal 300 receives input of the name of the visitor, the company name of the company to which the visitor belongs, and the department name. In addition, the reception terminal 300 receives an input of a monitoring level indicating a degree of monitoring of a visitor and a possible area name that is a name of an area (hereinafter, also referred to as a possible area) where the visitor can enter.

  A reception-side camera 310 provided at the reception acquires image data by capturing the face of a visitor who enters the data center. Then, the reception-side camera 310 outputs the acquired image data to the reception terminal 300.

  The reception terminal 300 allocates the visitor ID to the visitor during the entrance procedure. The reception terminal 300 receives the assigned visitor ID, the image data output by the reception-side camera 310, the name of the input, the company name, the department name, the monitoring level, and the possible area name. Is output to the monitoring processor 100.

  Based on the output possible area name, the monitoring processing device 100 calculates a route through which the visitor passes from the entrance in the server management room to the area of the possible area name. The route is a set of a plurality of coordinates in the server management room.

  In addition, the monitoring processing apparatus 100 extracts feature image data 1 to 5 from the image data output from the reception terminal 300. The monitoring processing apparatus 100 stores the visitor ID in association with the extracted feature image data 1 to 5 in the visitor image data storage unit 120.

  In addition, the monitoring processing device 100 stores the visitor ID, the company name input at the reception, the department name, and the name in association with each other in the visitor affiliation information storage unit 130.

  In addition, the monitoring processing device 100 stores the visitor ID, the monitoring level, the prohibited area name, and the calculated route in the monitoring information storage unit 140 in association with each other.

  Here, as shown in FIG. 2, the server management room includes a plurality of prohibited areas 210 contracted for each customer, a caution area 220 that surrounds the outer periphery of the prohibited area 210, and an air conditioner 230. Exists. Each forbidden area 210 is provided with a server for storing corresponding customer data. In addition, a marker indicating the boundary line of each area is attached to the floor of the server management room, and the corresponding customer is identified by the color of the marker.

  A plurality of surveillance cameras 200 are attached to the four corners of the ceiling of the server management room. The attachment position of the monitoring camera 200 may be changed as appropriate according to the shape of the server management room. Each surveillance camera 200 tracks and images a visitor who moves in the server management room. As a result, the visitors are imaged from different directions by the respective monitoring cameras 200.

  Each surveillance camera 200 acquires image data by imaging the visitors. Each monitoring camera 200 outputs the acquired image data to the monitoring processing device 100.

  The monitoring processing device 100 synthesizes image data output from each monitoring camera 200 to acquire one image data. Thereby, the monitoring processing apparatus 100 can acquire image data that captures the entire server management room. Then, the monitoring processing device 100 monitors the approach of the visitor to the caution area 220, the entry into the prohibited area 210 and the caution area 220, the approach to the air conditioner 230, and the like.

  The monitoring processing unit 110 of the monitoring processing apparatus 100 detects the face of the visitor from the image data output from each monitoring camera 200. For the monitoring processing device 100 to detect the face of a visitor, for example, HOG (Histogram of Oriented Gradient) is used. More specifically, the monitoring processing apparatus 100 divides the face into a plurality of small areas, and extracts a HOG feature amount indicating the gradient direction and strength of the edge in each small area. Thereafter, the monitoring processing device 100 identifies whether the region in the image is a human face or the other based on the extracted HOG feature amount using machine learning technology such as SVM (Support Vector Machine) or Adaboost, for example. And detect the face. Note that feature quantities such as Haar and LBP may be extracted, and a face from image data may be detected based on the extracted feature quantities.

In addition, the monitoring processing unit 110 searches the monitoring information storage unit 140 using the visitor ID of the specified visitor as a key, and acquires a possible area name, a prohibited area name, and a route.

  Based on the image data output from each monitoring camera 200, the monitoring processing unit 110 of the monitoring processing apparatus 100 calculates the coordinates of the standing position of the visitor in the server management room (hereinafter sometimes referred to as visitor coordinates). To do. In addition, the monitoring processing unit 110 holds the calculated visitor coordinates.

  The monitoring processor 110 calculates a visitor movement vector based on the calculated plurality of visitor coordinates. For example, the monitoring processing unit 110 calculates, as the visitor movement vector, a vector from the visitor's coordinates calculated one second before the present time to the visitor's coordinates calculated at the present time.

  The monitoring processing unit 110 determines whether a visitor has approached the attention area 220. Here, an area area storage unit (not shown) of the monitoring processing device 100 stores the prohibited area name of each prohibited area 210 and the coordinates of the boundary line of each prohibited area 210 in association with each other. The area area storage unit stores the caution area name of each caution area 220 and the coordinates of the boundary line of each caution area 220 in association with each other. Further, the area area storage unit stores the possible area name of each possible area where the visitor can enter and the coordinates of the boundary line of each possible area in association with each other.

When it is determined that the area where the visitor has entered is not the caution area 220 or the prohibited area 210, the monitoring processing unit 110 determines that the visitor ID, the visitor's image data, and the visitor has entered the area. And the area name (name of the intruded area) and “warning unnecessary” indicating that no warning is necessary are stored in the monitoring result storage unit 150 in association with each other.

  Here, the monitoring processing unit 110 determines whether the visitor coordinates are located in the caution area 220 based on the visitor coordinates and the coordinates of the boundary line of the caution area 220. When it is determined that the visitor coordinates are located within the attention area 220, the monitoring processing unit 110 determines that the visitor has entered the attention area 220.

  Further, the monitoring processing unit 110 determines whether or not the visitor coordinates are located in the prohibited area 210 based on the visitor coordinates and the coordinates of the boundary line of the prohibited area 210. When determining that the visitor coordinates are located within the prohibited area 210, the monitoring processing unit 110 determines that the visitor has entered the prohibited area 210.

  When it is determined that the area where the intruder has entered is the caution area 220 or the prohibited area 210, the monitoring processing unit 110 determines that the information indicating that a warning for the visitor is necessary is necessary for the warning. A warning request signal is generated to be output together with “entering the caution area” or “entering the prohibited area”. Then, the monitoring processing unit 110 outputs the generated warning request signal to the administrator terminal 400. Thereafter, the administrator terminal 400 outputs information indicating that a warning for the visitor is necessary. Further, the monitoring processing unit 110 acquires the acquired visitor ID, the output image data of the visitor, the date and time when it is determined that the visitor has entered the caution area 220 or the prohibited area 210, and the area name (intruded (Name of area) and “intrusion into caution area” or “intrusion into prohibited area”, which are the reasons for determining that a warning is necessary, are stored in the monitoring result storage unit 150 in association with each other.

  By storing the monitoring result in the monitoring result storage unit 150, the information displayed in the intrusion area or the prohibited area 210 is displayed along with the date and time by selecting the information stored in the monitoring result storage unit 150 at a later date. It becomes possible to confirm.

  In addition, the monitoring processing unit 110 may transmit an e-mail describing that a warning to a visitor is necessary to the administrator terminal 400 together with the reason for determining that a warning is necessary. The administrator terminal 400 that has output the warning request signal may turn on a patrol lamp attached to the administrator terminal 400.
