(Details of analysis result screen)
Next, a specific example of the analysis result screen by the whole area map screen 55 or the area map screen 56 used when displaying the camera image of the surveillance image and the post-analysis image including the image analysis result, and the display operation of the analysis result screen will be described.

FIG. 19 is a flowchart showing an example of the icon display process according to the embodiment. Here, an example in which the processing unit 11 of the image analysis control device 10 proactively performs processing is shown. The video monitoring terminal device 40 may execute some or all of the processing.

The processing unit 11 of the image analysis control device 10 acquires the map information of the monitoring area in the surveillance camera management system from the image analysis management server 31 or another map information distribution server (S31). The processing unit 11 uses the acquired map information to generate an area map screen 56 including a map of the monitoring area. Next, the processing unit 11 acquires the information of the surveillance camera 20 and arranges the camera icon of the surveillance camera on the map of the area map screen 56 (S32). Further, the processing unit 11 acquires the image analysis result for each time of each camera from the image analysis server 32, and arranges an active icon indicating the status of the image analysis in the vicinity of the periphery of the camera icon (S33). The active icon is an icon representing an analysis state such as image analysis in progress / unanalyzed. The active icon may represent the density and movement direction of the crowd detected in the analysis area. Further, when the predetermined alert condition is satisfied in the image analysis result, the processing unit 11 acquires the alert information from the image analysis server 32 and arranges the alert icon indicating the content of the alert in the vicinity of the vicinity of the camera icon (S34). .. The alert icon is an icon indicating an alert occurrence state in analysis functions such as intrusion detection, suspicious object detection, and feature detection. Then, the processing unit 11 causes the display unit 13 to display the area map screen 56 including the camera icon, the active icon, and the alert icon on the map (S35).

FIG. 20 is a diagram showing a display example of the entire area map screen 55 of the surveillance camera management device according to the embodiment. When the image analysis control device 10 receives an instruction to display the analysis result screen by the operation input from the user, the image analysis control device 10 displays the whole area map screen 200 showing the whole area or the wide area of the monitored area. On the whole area map screen 200, a map of the entire area or a wide area of the monitored area is displayed, and the area icon 201 is arranged and displayed corresponding to the position of a specific area where the surveillance camera is arranged.

The area icon 201 is an icon indicating the position of a specific area in the monitored area. The area icon 201 indicates, for example, whether at least one of the surveillance cameras in the detection target area at the position indicated by the icon is currently performing image analysis or unanalyzing in real time, and indicates whether the surveillance camera in the area is being analyzed. At least one indicates whether an alert has occurred (with alert) or no alert has occurred (no alert). In the illustrated example, the area under image analysis is indicated by a broken line frame, the area without alert is indicated by a diagonal line pattern, and the area with alert is indicated by a dot pattern. The area icon 201 allows the user to easily determine the image analysis status and the alert generation status for each area.

FIG. 21 is a diagram showing a display example of the area map screen 56 of the surveillance camera management device according to the embodiment. On the whole area map screen 200, the image analysis control device 10 displays the area map screen 210 showing the selected specific area when the user clicks and specifies the area icon of any area. The area map screen 210 displays a map of the corresponding area, and the camera icon 211 is arranged and displayed corresponding to the position of the surveillance camera arranged in the area. The camera icon 211 indicates the position where the surveillance camera is arranged, but may indicate the shooting direction of the camera. Further, the camera icon 211 of the illustrated example includes an element of an active icon indicating whether the image analysis is currently being performed or has not been performed in real time with respect to the surveillance camera at the corresponding position, or the status of the image analysis. In the illustrated example, the camera during image analysis is indicated by a broken line frame. Further, the camera icon 211 may indicate the detection type of the function currently being analyzed. The term "unanalyzed" here includes the fact that the analysis has not been performed. In other words, the state before analysis is also unanalyzed, and it returns to the unanalyzed state even after the analysis is completed.

Further, on the area map screen 210, the image analysis control device 10 displays an icon indicating the analysis result of the surveillance image. When the analysis result of the analysis function satisfies the alert condition, an alert icon indicating that an alert has occurred in the surveillance image of the corresponding surveillance camera is displayed around each of the camera icons 211 to 214. It is displayed in association with each. In addition, the analysis status and analysis result of the crowd estimation function are displayed around the camera icon of the surveillance camera to which the analysis status icon corresponds, as an icon different from the alert icon. The analysis status icon includes elements of an active icon and an alert icon. The analysis status icon indicates the degree of density of the crowd in a plurality of stages by color, pattern, etc., such as no crowd density information / crowded / slightly crowded / not crowded as the analysis result. As an analysis result, the analysis status icon indicates the direction of movement of the crowd, with or without the direction of travel, by the arrow indicating the direction of movement (direction of travel).

The alert icon disappears by checking the alert content of the specific analysis function for which the alert is occurring for each surveillance camera and changing the alert to the supported state. The alert icon may disappear after being separated by time. For example, if 24 hours have passed since the alert was generated, the alert icon is turned off even if it has not been changed to the supported state. In addition, when the analysis is being performed again after the analysis is in the unanalyzed state, the alert icon displayed during the previous analysis is temporarily turned off, and an alert is generated during this analysis. If this happens, the alert icon may be displayed again. In this way, by turning off the display of the alert icon, which seems to be less important, the user can easily find the alert that needs to be dealt with now.

An example of the illustrated camera icon 211 will be described. The surveillance camera corresponding to the camera icon 211 is performing image analysis, and as a result of the analysis, an alert is generated in the feature detection function, the suspicious object detection function, and the intrusion detection function. Also, the analysis result of the crowd estimation shows that the crowd is moving downward on the road in a crowded state. At this time, as the alert icon 221, a feature detection icon indicating an alert of the feature detection function, a suspicious object icon indicating an alert of the suspicious object detection function, and an intrusion icon indicating an alert of the intrusion detection function are displayed. As the analysis status icon 231, a down arrow indicating that the crowd is moving downward on the road is displayed at an angle along the road on a red background indicating a crowded state.

An example of the illustrated camera icon 212 will be described. The surveillance camera corresponding to the camera icon 212 is performing image analysis, and as a result of the analysis, an alert is generated in the feature detection function. Also, the analysis result of the crowd estimation shows that the crowd is moving to the left on the road in a crowded state. At this time, as the alert icon 222, a feature detection icon indicating an alert of the feature detection function is displayed. As the analysis status icon 232, a left arrow indicating that the crowd is moving to the left on the road is displayed at an angle along the road on a red background indicating a crowded state.

An example of the illustrated camera icon 213 will be described. The surveillance camera corresponding to the camera icon 213 is performing image analysis, and as a result of the analysis, no alert is generated. Also, the analysis result of the crowd estimation shows that the crowd is moving to the right on the road in the uncrowded state. At this time, the alert icon is not displayed, and as the analysis status icon 233, the right arrow indicating that the crowd is moving to the right on the blue background indicating the uncrowded state is the angle along the road. Is displayed.

An example of the illustrated camera icon 214 will be described. The surveillance camera corresponding to the camera icon 214 does not perform image analysis. Therefore, there is no analysis result and no alert is generated. Similarly, since the crowd estimation has not been analyzed, there is no density information. At this time, the alert icon is not displayed, and the analysis status icon 233 on a gray background indicating the state without density information is displayed as the analysis status icon 233.

Further, instead of the alert icon, the function currently being analyzed may be illustrated by the symbol of the icon so as to be discriminated, and the analysis function icon indicating the presence / absence of an alert and the analysis being / unanalyzed may be displayed by the color or pattern. For example, regarding the alert icon 221, a red icon is displayed when an alert is generated, and a gray icon is displayed with the same pattern when an alert is being analyzed but no alert is generated. By doing so, not only can the user easily determine the function for which the alert has occurred, but also the user can easily determine the function for which analysis is being performed.

When displaying the camera icon and the alert icon in association with each other, the camera icon and the alert icon may be displayed as one icon including the elements of the camera icon and the alert icon, or the alert icon may be displayed as the same icon as the camera icon. For example, it is conceivable to enlarge the frame of the camera icon 211 so that the alert icon 221 is displayed in the frame.

When the crowd estimation function was not analyzed for the image of the surveillance camera, the analysis status icon indicating that there was no density information was displayed, but the analysis status icon itself may be hidden. By doing so, it is possible to simplify the display when the analysis is not performed.

In this way, the camera icon 211 allows the user to easily determine the image analysis status for each camera. Further, the alert occurrence status and the image analysis result can be easily discriminated by the alert icon 221 and the analysis status icon 231.

From the display state of the area map screen 210, the image analysis control device 10 can return to the whole area map screen 200 and display it by the operation input of the user. Further, on the area map screen 210, it is possible to display the main screen 60 or the alert confirmation screen 70 including the corresponding camera and area by designating a specific camera and area by the operation input of the user. When an arbitrary camera icon 211 is selected by the user's operation input, the image analysis control device 10 displays the image data of the surveillance camera corresponding to the selected camera icon 211 on the display unit 13 of the own device or the video monitoring terminal device 40. Is displayed on the user terminal such as.

According to the embodiment, when a plurality of functions different on the time axis are set in the surveillance camera and an event that satisfies the alert condition occurs, which camera is analyzed by which function depends on which function. The user can easily grasp whether an alert has occurred. In addition, the icon displayed on the map allows the user to easily grasp where the camera placed in the camera alerted by the function. Further, even when the alert is not generated, the user can easily grasp which function is being analyzed by which camera during the analysis of the surveillance image or in the analysis result.

As described above, the surveillance camera management device, the surveillance camera management system, the surveillance camera management method and the program of the present embodiment analyze a plurality of surveillance cameras for at least one of the plurality of surveillance cameras 20 in the surveillance area. Assign at least one analysis function from the functions according to the time. For example, one of a plurality of image analysis functions such as crowd estimation, intrusion detection, suspicious object detection, and feature detection is assigned according to the time. Further, on the map including the surveillance area, the camera icon 211 corresponding to each position of the plurality of surveillance cameras 20 and the analysis result of the analysis function assigned to at least one of the plurality of surveillance cameras 20 are alerted. When the condition is satisfied, the user terminal is displayed with a screen including an alert icon 221 associated with the camera icon 211 corresponding to the surveillance camera to be alerted. The alert icon 221 can determine the analysis function that satisfies the alert condition. For example, an alert icon corresponding to the assigned analysis function and an alert icon different depending on the analysis function are displayed. This makes it possible to easily recognize a plurality of functions, states, and the like in response to the functions that can be set in the surveillance camera according to the time. For example, when a plurality of functions are assigned to the surveillance camera for each time, the user can easily grasp which analysis function caused the alert at a specific time such as the current time.

Further, when the camera icon 211 is selected by a user operation or the like, the surveillance camera management device causes the user terminal to display the imaging data of the surveillance camera corresponding to the selected camera icon 211. As a result, by selecting and specifying the camera icon, it is possible to confirm the surveillance image based on the captured data of the desired surveillance camera corresponding to the camera icon.

In addition, the surveillance camera management device displays the alert icon 221 around the camera icon 211. Thereby, the user can easily grasp which surveillance camera the alert is related to by the camera icon 211 and the alert icon 221.

In addition, the surveillance camera management device displays the alert icon and the camera icon as one icon. For example, it is displayed by one icon including the elements of the camera icon and the alert icon, or the alert icon is displayed as the same icon as the camera icon. As a result, the user can easily grasp which analysis function is operating and which analysis function alerts are generated in the surveillance camera corresponding to the icon.

In addition, when the surveillance camera management device assigns different analysis functions to at least one surveillance camera according to the time and displays an alert icon, the alert icon corresponding to each analysis function assigned to the surveillance camera is assigned. Display it. As a result, when different analysis functions are assigned according to the time, which analysis function is operating among multiple functions such as intrusion detection is alerted by the alert icon corresponding to each analysis function. The user can easily grasp whether it has occurred.

Further, when the analysis result of the analysis function does not satisfy the alert condition, the surveillance camera management device displays an icon different from the alert icon 221 in association with the camera icon 211 corresponding to the surveillance camera. For example, as a different icon, an analysis status icon 231 indicating the analysis status of a function such as crowd estimation is displayed. As a result, when an alert has not occurred, it is possible to easily recognize a plurality of functions, states, and the like in response to the functions that can be set in the surveillance camera according to the time. For example, at a specific time such as the current time, the user can easily grasp which analysis function is performing the analysis and what state the analysis result is in.

Further, when the surveillance camera management device assigns different analysis functions to at least one surveillance camera according to the time and displays different icons, the surveillance camera management device displays the icons corresponding to the respective analysis functions assigned to the surveillance cameras. Let me.
