[First Embodiment]
In the present embodiment, an example of an information processing apparatus having the following configuration will be described. That is, this information processing apparatus includes a small area in which a first score representing a first monitoring effect is less than a specified value among a plurality of small areas constituting a map indicating a monitoring area, and a second representing a second monitoring effect.

Select and output based on the first and second scores of the region. First, a functional configuration example of the information processing apparatus according to the present embodiment will be described with reference to the block diagram of FIG.

  The holding unit 101 stores a two-dimensional plan view overlooking a space (target space) in which cameras and personnel are arranged. An example of a two-dimensional plan view stored in the holding unit 101 is shown in FIG. The two-dimensional plan view of FIG. 3 shows the layout of walls, shelves, and passages, as well as the layout of personnel. A two-dimensional plan view is a two-dimensional image, and each pixel has an attribute such as whether the pixel belongs to a wall, a shelf, or a passage. In addition, you may employ | adopt another method as a method of distinguishing whether each pixel of a two-dimensional plan view belongs to a wall, it belongs to a shelf, or it belongs to a passage. The two-dimensional plan view is attached with data (scale data) indicating the scale of the two-dimensional plan view, and the correspondence between the distance in the real space and the distance in the two-dimensional plan view is known. It shall be. However, any data may be provided as long as the distance on the two-dimensional plan view corresponds to the distance in real space (or vice versa).

  The holding unit 102 stores arrangement information indicating the position and direction of the camera (existing camera) already installed in the target space on the two-dimensional plan view. The holding unit 102 may store the position and direction of the existing camera in the target space, and may convert the position and direction into a position and direction on a two-dimensional plan view using the scale data.

  In the case of changing the layout or the like for a monitoring area in which cameras are already installed, the camera arrangement is performed by utilizing the arrangement of the existing cameras. If the existing camera can be rearranged, all the cameras are newly arranged without using this information.

  The holding unit 103 stores information indicating an area (monitoring area) on the two-dimensional plan view corresponding to an area to be monitored by a camera or personnel in the target space. The monitoring area may be the entire two-dimensional plan view or a part of the area. The monitoring area can be appropriately set by the user, for example. Hereinafter, in order to simplify the description, the entire area of the two-dimensional plan view is set as a monitoring area.

  In the holding unit 104, when the monitoring area in the two-dimensional plan view is divided into a plurality of partial areas, a value indicating the effect of shooting by the camera and a value indicating the effect of suppressing the event by the camera or personnel for each partial area , Values indicating monitoring effects based on these effects are stored. In the process described below, the position and direction of the camera to be arranged in the target space are determined based on these values.

  The DB (database) 105 stores specification data of the above-described existing cameras and cameras to be arranged in the target space. An example of the specification data stored in the DB 105 is shown in FIG.

  The holding unit 106 stores the size of an object (monitoring target object) to be detected by monitoring by a camera or personnel.

  The generation unit 107 is a function that represents the relationship between the distance from the camera to the object (the object having the size held by the holding unit 106) and the effect of shooting by the camera for the camera whose specifications are stored in the DB 105. A shooting effect function is generated.

  The generation unit 108 is a function that represents the relationship between the distance from the camera to the object (the object having the size held by the holding unit 106) and the effect of suppression by the camera for the camera whose specifications are stored in the DB 105. Generate a deterrent effect function.

  The generation unit 109, for each person whose arrangement is defined in the two-dimensional plan view, the relationship between the distance from the person to the object (the object having the size held by the holding unit 106) and the deterrence effect by the person A deterrence effect function that is a function representing

  The generation unit 110 generates a plurality of arrangement patterns (arrangement position and direction patterns) of cameras to be arranged in the target space.

  The selection unit 111 selects one or more arrangement patterns in descending order of the monitoring effect from the plurality of arrangement patterns generated by the generation unit 110. The presentation unit 112 outputs the arrangement pattern selected by the selection unit 111. The control unit 199 performs operation control of each functional unit described above.

  Next, when one or more cameras are newly installed in the target space where the existing cameras are arranged, the processing performed by the information processing apparatus to present to the user what kind of arrangement pattern is present Description will be made with reference to FIG. 6 showing a flowchart.

  In step S601, the control unit 199 reads a two-dimensional plan view (management area drawing) from the holding unit 101. In step S602, the control unit 199 reads information indicating the management area from the holding unit 103, and sets a monitoring area on the two-dimensional plan view based on the information. As described above, in this embodiment, the entire area of the two-dimensional plan view is the monitoring area. In step S603, the control unit 199 reads the specification data of each camera from the DB 105.

  In step S604, the control unit 199 initializes a management effect table as illustrated in FIG. Specifically, as shown in FIG. 7A, the monitoring area is divided into a plurality of partial areas (mesh), and the photographing effect value and the suppression effect value in the partial area are initialized to zero. In the monitoring effect table, for each partial area, the coordinate value of the partial area in the monitoring area (the coordinate value of the center of the partial area) and the shooting effect value and the suppression effect value in the partial area are registered in association with each other. It is a table that was made.

  In step S <b> 605, the control unit 199 reads the arrangement information of each existing camera from the holding unit 102. In step S606, the generation unit 107 and the generation unit 108 generate a shooting effect function and a suppression effect function for each existing camera, and use the generated shooting effect function and the suppression effect function in the corresponding partial area in the monitoring area. Obtain the shooting effect value and the suppression effect value.

  First, shooting effect function generation processing by the generation unit 107 will be described. Here, the case where the imaging | photography effect function of the existing camera A is produced | generated is demonstrated. As shown in FIG. 5A, the distance from the existing camera A to the object when the object is placed at the center position of the field of view of the existing camera A is d (m), and the horizontal angle of view of the existing camera A (DB105 Is the specification of the existing camera A registered in (1). At this time, the visual field width w (m) of the existing camera A can be obtained as w = 2 × d × tan (θ / 2). When the existing camera A has a zoom function, the maximum field angle of the existing camera A is set as the horizontal field angle θ.

  If the video shot by the existing camera A is full HD, w corresponds to 1920 pixels. Therefore, for example, if the size of the object stored in the holding unit 106 is 0.1 m, the size of the object on the captured image by the existing camera A is calculated as (1920 × 0.1 / w) pixels. Can do. As described above, since the size of the object on the video image captured by the existing camera A corresponding to the distance from the existing camera A to the object is known, the following characteristics are obtained as the shooting effect function fA (d) of the existing camera A. Generate a function with

FA (d) = 1 in the range of the distance d such that the size of the object on the photographed video is not less than the first size (for example, 20 pixels).
In the range of the distance d such that the size of the object on the photographed video is less than the second size (for example, 5 pixels), fA (d) = 0
In the range of the distance d such that the size of the object on the photographed video is less than the first size and greater than or equal to the second size, fA (d) = monotonically decreases as the distance d increases (maximum value 1, minimum value). 0)
An example of such a shooting effect function is shown in FIG. Note that when the existing camera A is an HD camera, the resolution of the captured video by the existing camera A changes, so the shooting effect function is a function as shown in FIG.

  Next, generation of the deterrence effect function fB (d) of the existing camera A will be described. The generation method of the deterrence effect function fB (d) of the existing camera A is basically the same as the shooting effect function, but the person to be monitored does not know the exact specifications of the existing camera A such as resolution and angle of view. Therefore, it is made wider than the range where the photographing effect is covered. For example, the horizontal angle of view θ used when obtaining the shooting effect function is made wider (for example, + 3 °), and the vertical direction angle of view is made wider. Further, parameters such as an angle of view for obtaining the suppression effect function fB (d) may be registered in the DB 105 separately from the specification data.

  The shooting effect function fA (d) and the suppression effect function fB (d) described above are obtained for each existing camera whose specifications are registered in the DB 105. When the shooting effect function fA (d) and the suppression effect function fB (d) of each existing camera are obtained, the generation unit 107 and the generation unit 108 perform the following process for each existing camera.

  The generation unit 107 identifies the field of view of the target existing camera in the monitoring area using the position and direction of the target existing camera on the monitoring area (obtained in step S605) and the angle of view of the target existing camera. Then, the generation unit 107 adds a function value fA (d) of the shooting effect function corresponding to the distance d from the existing camera of interest to the shooting effect value of the partial area for each partial area in the identified field of view. To update the photographing effect value.

  As shown in FIG. 8, the generation unit 108 sets a circular area centered on the position of the existing camera of interest and having a specified length radius on the monitoring area, and a portion that can be photographed from the existing camera of interest within the circular area Count the number of regions. That is, the total number of partial areas excluding the partial areas that cannot be viewed by the existing camera of interest due to obstacles among all the partial areas in the circular area is counted. For determining whether or not the target partial area is visible from a certain viewpoint, for example, a line segment passing between the position of the viewpoint on the monitoring area and the target partial area is a pixel whose attribute is an obstacle such as a wall or shelf When passing through, it is determined that the target partial area is not visible from the viewpoint. On the other hand, if the line segment that passes between the position of the viewpoint on the monitoring area and the target partial area does not pass through pixels that are obstacles such as walls and shelves, the target partial area is determined to be visible from the viewpoint. . Then, the generation unit 108 obtains a recognition score based on the counted total number. For example, a result obtained by dividing the total number by 100 is defined as a recognition score. When the total number is 100 or more, the recognition score = 1.0. Then, the generation unit 108 corrects the maximum value of the suppression effect function of the existing camera of interest to (maximum value × recognition score). Then, the generation unit 108 identifies the field of view of the target existing camera in the monitoring area using the position and direction of the target existing camera on the monitoring area (acquired in step S605) and the angle of view of the target existing camera. Then, for each partial area in the identified field of view, the generation unit 107 uses a suppression effect function corresponding to the distance d from the existing camera of interest (the maximum value is corrected using the recognition score). The function value fB (d) of (completed) is added to update the suppression effect value. When no existing camera is installed in the target space, the shooting effect value and the suppression effect value of all partial areas are zero.

  In step S607, the generation unit 109 generates a deterrence effect function for each person. The deterrence effect function for personnel is, for example, a monotonically decreasing function that has a function value of 1.0 when distance = 0 and a function value of 0.0 when distance = dth (= specified value). . Then, the generation unit 109 sets, for each personnel, the deterrence effect value of the partial region that is visible to the personnel among the partial regions in the monitoring area, and the function value corresponding to the partial region in the deterrence effect function obtained for the personnel. Is added to update the deterrence effect value.

  By performing the processing of steps S608 to S611 for each arrangement pattern of cameras to be arranged in the target space, a plurality of arrangement patterns of the cameras are generated. In step S608, a copy of the shooting effect value and the suppression effect value determined at the end of step S607 is created. In steps S609 to S611, processing is performed on this copy. Since the arrangement of the camera can generate a large number of arrangement patterns depending on how the first one is placed, a plurality of determination methods for the first one are prepared, and the processing of steps S608 to S611 is repeated for this number. Generate a placement pattern.

  In step S609, the generation unit 110 generates an arrangement pattern of cameras to be arranged in the target space based on the shooting effect value in the monitoring area. Details of the processing in step S609 will be described with reference to the flowchart of FIG.

  In step S901, the generation unit 110 determines whether or not there is a partial region in which the shooting effect value is less than the specified value among the partial regions in the monitoring area. As a result of the determination, if it exists, the process proceeds to step S902. If it does not exist, the process proceeds to step S610.

  In step S902, the generation unit 110 selects an unselected one of the partial areas whose photographing effect value is less than the specified value as the selected partial area (actually, obtains the coordinate position of the selected partial area). There are various methods for selecting the selected partial region. For example, when there is an existing camera, a partial area of the shooting effect value that maximizes the difference from the specified value may be selected. When there are a plurality of partial areas where the shooting effect value is less than the specified value, the distance from the four corners of the monitoring area is obtained for each of the plurality of partial areas, and the partial area where the obtained distance is the minimum is selected. Also good. Further, when there are a plurality of partial areas where the shooting effect value is less than the specified value, the distance from the central position of the monitoring area is obtained for each of the plurality of partial areas, and the partial area where the obtained distance is maximum or minimum May be selected. It is assumed that the partial area selection method in step S902 is set in advance.

  In step S903, the generation unit 110 selects a camera designated as a usable camera among the cameras whose specifications are stored in the DB 105 as a selected camera, and a desired shooting effect value in the shooting effect function of the selected camera. To obtain the distance dr. For example, as shown in FIG. 9B, when the desired shooting effect value = 0.8, the distance dr with which the function value is 0.8 in the shooting effect function is specified. Then, as shown in FIG. 9C, the generation unit 110 obtains a circle having the radius of the distance dr acquired in step S903 with the position of the selected partial region as the center, and inside the circle near the circumference of the camera. Placement position and direction candidates are set.

  Here, candidates are set by constraining the camera placement position and direction. For example, there are restrictions such that the direction of the camera in the monitoring area is the horizontal direction or the vertical direction, if it is a passage, it is placed in the center, and the distance from the nearest camera is a certain value or more. In any case, the selected partial area needs to be included in the field of view of the camera.

  In step S904, when the generation unit 110 arranges the camera at the arrangement position and direction candidates set in step S903, the imaging effect value and the suppression effect corresponding to the distance from the camera of the corresponding partial region in the monitoring area. The value is obtained in the same manner as in step S606.

  In step S610, the generation unit 110, if there is a partial region whose deterrence effect value is less than the specified value among the respective partial regions in the monitoring area, is not selected among the partial regions whose deterrence effect value is less than the specified value. Is selected as a selected partial region. Actually, the coordinate position of the selected partial region is acquired. The selection method is the same as in step S902 above. Then, the generation unit 110 selects a camera designated as a usable camera among the cameras whose specifications are stored in the DB 105 as a selected camera, and a distance that provides a desired shooting effect value in the suppression effect function of the selected camera. Get dr. Then, the generation unit 110 obtains a circle centered on the position of the selected partial region and having the acquired distance dr as a radius, and sets a camera placement position and direction candidate in the vicinity of the circumference in this circle. This setting method is the same as step S903 described above. Then, the generation unit 110 performs the same process as in step S904. Since the shooting effect of the camera may be minimal, for example, by selecting a camera with a low resolution at a reduced price of the VGA resolution, the camera can be arranged so as to reduce the total cost of the camera.

  Since a plurality of arrangement patterns are generated when the process proceeds to step S612, the selection unit 111 selects one or more of the plurality of arrangement patterns in step S612. The selection criteria are not limited to specific selection criteria. For example, for each arrangement pattern, the sum of the shooting effect value and the suppression effect value on the monitoring area corresponding to the arrangement pattern is obtained as the monitoring effect, and the top one is calculated in descending order of the obtained sum (in descending order of the monitoring effect). The above arrangement pattern may be selected.

  In step S613, the selection unit 111 obtains the priority order of each camera arranged in the monitoring area for each arrangement pattern selected in step S612. For example, the sum S1 of the photographing effect value and the suppression effect value of each partial area in the monitoring area determined for the target arrangement pattern is obtained. An unselected one of the cameras installed in the monitoring area according to the target arrangement pattern is selected as the selected camera, and the sum S2 of all the shooting effect values and the suppression effect values in the monitoring area when the selected camera is not arranged. A series of calculations is performed for each camera. The camera selected as the selected camera when S2 having a larger difference from S1 is obtained becomes a camera with higher importance (priority order).

  In step S614, the presentation unit 112 outputs the arrangement pattern selected in step S612 and the priority order of each camera obtained in step S613 for the arrangement pattern. The output destination and output form of the arrangement pattern and priority by the presentation unit 112 are not limited to a specific output destination and output form. For example, if the object representing the camera is arranged in a layout according to the arrangement pattern on the two-dimensional plan view, and the display form (color, size, etc.) of the object of each camera is changed according to the priority order, the monitoring effect A list is displayed on the display device 209 in descending order. Of course, the display order is not limited to this. The priority order may be displayed as a character string.

  Thus, according to this embodiment, it is possible to generate a plurality of surveillance camera placement patterns in the surveillance area and to assign camera priorities in each placement pattern. Also, by presenting the priority order, if the overall cost does not match and you want to reduce the number of cameras, the user can know the camera with the lower priority order, delete it manually, replace it with another camera, etc. It will be possible to provide a configuration to try.
