In particular, the present invention captures a predetermined area, images a moving object in the area, and easily obtains an image desired by a user from among the resulting images. The present invention relates to an information processing apparatus, a program , and an information processing method that can be reproduced in a simple manner .

  In recent years, for example, in many banks, parking lots, houses, etc. where automatic teller machines (ATMs) are installed, a multi-point camera monitoring system (Multi Camera system) is installed to ensure security.

  Such a multi-point camera monitoring system is composed of a plurality of video cameras and a recording device that records images acquired from these video cameras. In the multipoint camera monitoring system, a technique has been proposed in which a plurality of images are reduced and combined to form one frame image. (For example, refer to Patent Document 1). It has also been proposed to collect images from a plurality of video cameras and record them on a recording medium such as a video tape (for example, see Patent Document 2).

  FIG. 1 is an external view showing an example of a conventional multipoint camera monitoring system.

  The multipoint camera monitoring system 1 in FIG. 1 includes four cameras 11-1 to 11-4. The cameras 11-1 to 11-4 are fixed cameras with fixed shooting directions or pan / tilt / zoom cameras with variable shooting directions. The cameras 11-1 to 11-4 monitor, for example, a wide circular area 21 having a diameter of 40 m in a parking lot.

  FIG. 2 shows an example of the configuration of the multipoint camera monitoring system 1 of FIG.

  The cameras 11-1 to 11-4 in FIG. Each of the cameras 11-1 to 11-4 is connected to the recording device 41 and supplies an analog signal of an image obtained as a result of photographing to the recording device 41. The recording device 41 performs A / D conversion or the like on the analog signals of the images supplied from the cameras 11-1 to 11-4, and records the image data that is the digital signals of the images obtained as a result. The recording device 41 is connected to the display device 42 and causes the display device 42 to display an image corresponding to the image data.

  However, in the multipoint camera monitoring system 1 of FIG. 2, the cameras 11-1 to 11-4 that can be connected to the recording device 41 are limited, and the multipoint camera monitoring system 1 has poor expandability.

  FIG. 3 shows another example of the configuration of the multipoint camera monitoring system 1 of FIG.

  The cameras 11-1 to 11-4 in FIG. 3 are connected to a personal computer (PC) 52 via a network 51, respectively. The cameras 11-1 to 11-4 perform shooting, and transmit image data obtained as a result to the PC 52 via the network 51 in accordance with IP (Internet Protocol). The PC 52 records the image data or displays an image corresponding to the image data.

  Next, image data recorded on the recording device 41 or the PC 52 of FIG. 2 will be described with reference to FIG.

  As shown in FIG. 4, the recording device 41 or the PC 52 records all image data obtained by the cameras 11-1 to 11-4. Therefore, when monitoring is performed by the multipoint camera monitoring system 1, the capacity of the image data recorded in the recording device 41 or the PC 52 becomes very large even when the image data is compressed by a predetermined compression method.

Further, when the multi-point camera monitoring system 1 is composed of 8 cameras, the capacity is about 328 GB, and when it is composed of 16 cameras, the capacity is about 656 GB.

  As described above, in the multipoint camera monitoring system 1, four cameras 11-1 to 11-4 are required to monitor the region 21, and the installation is troublesome and the cost of the multipoint camera monitoring system 1 is increased. Becomes larger. Further, when acquiring a high-definition image, it is necessary to increase the shooting magnification, so that more cameras 11-1 to 11-4 are required. Further, if the number of cameras 11-1 to 11-4 is not increased in order to acquire a high-definition image, it is difficult to acquire a high-definition image for all the areas 21. It is necessary to monitor a normal image, specify a desired area, and acquire a high-definition image of the area.

  Therefore, there is a surveillance camera that can monitor a wide range of situations with one camera by photographing a subject while sequentially shifting the photographing direction and obtaining a panoramic overall image composed of a plurality of unit images. is there.

As shown in FIG. 10, the moving object detection module 222 detects occurrence at 10:00 on January 10, 2004 and detects the disappearance of the moving object assigned the moving object ID “1” at 11:00 on the same day. Further, the moving object detection module 222 determines the moving object frame 172 of the moving object having the moving object ID “1”, and the coordinates (1, 2), (1, 5), (2, 5) which are the coordinates of the vertices A to D thereof. , (2, 2) are recognized as occurrence positions.

  Further, the frame of the sensor image 151 in which the occurrence of the moving object with the moving object ID “1” is detected is the frame # 1 which is the first frame from the head, and the moving object detection module 222 reproduces the frame # 1 at the reproduction start position. Recognize as In the following, the l-th frame from the top is referred to as frame #l. Also, “1” is supplied to the sensor image acquisition module 221 as the camera ID of the sensor camera 121 that has acquired the sensor image 151 in which the generation of the moving object with the moving object ID “1” is detected.

  In addition, the moving object detection module 222 detects the disappearance of the moving object assigned the moving object ID “2” detected at 10:05 on January 10, 2004 at 10:30 on the same day. The moving body detection module 222 determines the moving body frame 172 of the moving body having the moving body ID “2”, and the coordinates of the vertices A to D of the moving body frame 172 are (3, 5), (3, 9), (5, 9) Recognize (5, 5) as occurrence positions.

  Further, the frame of the sensor image 151 in which the occurrence of the moving object with the moving object ID “2” is detected is the frame # 2, and the moving object detection module 222 recognizes the frame # 2 as the reproduction start position. Further, “1” is supplied to the sensor image acquisition module 221 as the camera ID of the sensor camera 121 that has acquired the sensor image 151 in which the generation of the moving object having the moving object ID “2” is detected.

  When the disappearance of the moving object to which the moving object IDs “1” and “2” are detected is detected, the sensor image acquisition module 221 generates the moving object, the disappearance date and time, the occurrence position, the moving object ID, the reproduction start position, and the camera ID. Is registered in the moving object information DB 227.

  FIG. 11 shows an example of the moving body log information registered in the moving body log information DB 228 of FIG.

  As illustrated in FIG. 11, the moving body log information includes a moving body ID and a zoom still image 272 </ b> C obtained by capturing a zoom image including the moving body of the moving body ID. For example, the zoom still image 272C is numbered from 1 in the order of acquisition, and hereinafter, the zoom still image 272C with the number p is referred to as a zoom still image # 1. In the moving body log information DB 228, a file is created for each management time zone, and the moving body log information is registered in a file corresponding to the management time zone including the date and time when the zoom still image 272C of the moving body log information is acquired. .

  In FIG. 11, the tracking target image acquisition module 223 acquires the zoom still image 272C obtained by capturing the zoom image 152 of the moving object having the moving object ID “1” for two frames of the zoom still images # 1 and # 2. The tracking target image acquisition module 223 acquires the zoom still image 272C of the moving object having the moving object ID “2” for one frame of the zoom image # 10.

  The tracking target image acquisition module 223 receives a moving object ID “1” and a moving object ID “1” zoom still image 272C, and a moving object ID “2” and a moving object ID “2” moving object zoom still image 272C. Information is registered in the moving object log information DB 228.

  FIG. 12 shows an example of the recording performance information registered in the recording performance information DB 229.

  As shown in FIG. 12, the recording performance information is composed of a sensor flag indicating whether the sensor image 151 is stored and a zoom flag indicating whether the zoom image 152 is stored, and is registered in association with the management time zone. .

  In FIG. 12, in the management time zone from 10:00 to 11:00 on January 10, 2004, the sensor image acquisition module 221 acquires the sensor image 151 and registers it in the display information DB 226, and the tracking target image acquisition module 223 acquires the zoom image 152 and registers it in the display information DB 226. That is, the sensor flag is “1” indicating that the sensor image 151 is stored, and the zoom flag is “1” indicating that the zoom image 152 is stored, for example.

  Further, the sensor image acquisition module 221 does not acquire the sensor image 151 and the zoom image 152 in the management time zone from 11:00 to 12:00 on January 10, 2004. That is, the sensor flag is “0” indicating that the sensor image 151 is not stored, and the zoom flag is, for example, “0” that indicates that the zoom image 152 is not stored.

  Next, the capacities of the sensor image 151 and the zoom image 152 stored in the display information DB 226 will be described with reference to FIG.

  As shown in FIG. 13, the display information DB 226 records all the sensor images 151 acquired by the sensor camera 121 and the zoom image 152 acquired by the zoom camera 122 when the occurrence of a moving object is detected. The

  In this way, in the monitoring system 101, the zoom image 152 is acquired and recorded only when the occurrence of a moving object is detected, so that the images acquired from the cameras 11-1 to 11-4 shown in FIG. The storage capacity of the display information DB 226 necessary for monitoring the area 21 can be reduced compared to the case where all are recorded.

  For example, when the sensor image 151 and the zoom image 152 are compressed and recorded in accordance with a JPEG (Joint Photographic Experts Group) system under a predetermined condition (50 KB / frame, 10 frames / second), the area 21 is monitored for 24 hours. The capacity of the sensor image 151 and the zoom image 152 necessary for this is about 51 GB. That is, compared with the multipoint camera monitoring system 1 shown in FIG. 4, the capacity of the display information DB 226 necessary for monitoring the area 21 is 1/60 to 1/3 or less.

  As a result, when the user (operator) reproduces the sensor image 151 and the zoom image 152 and performs a monitoring action, the zoom image 152 is not a zoom image 152 at all times but a zoom image at a time when a moving object that needs to be monitored is detected. Since only 152 can be reproduced, it is possible to reduce time and labor (quantitative man-hours) for the monitoring action.

  Further, by reducing the capacity of the sensor image 151 and the zoom image 152 stored in the display information DB 226, the reproduction module 231 can easily search for the sensor image 151 and the zoom image 152 to be reproduced.

  Next, an example of a screen displayed on the output unit 207 in FIG. 7 will be described with reference to FIGS.

  When the user operates the input unit 206 to command acquisition of the sensor image 151, the output unit 207 displays a screen 250 shown in FIG.

  14 is a sensor image display unit 251 that displays the sensor image 151, and an operation unit 252 that displays a GUI (Graphical User Interface) for instructing an operation related to recording (recording) of the sensor image 151 and the zoom image 152. , And a zoom image display unit 253 that displays a moving image of the zoom image 152.

  The sensor image acquisition module 221 causes the sensor image display unit 251 to display the sensor image 151 acquired now. Further, the tracking target image acquisition module 223 causes the zoom image display unit 253 to display the moving image of the zoom image 152 that is currently acquired.

  For example, a playback button 252A and a stop button 252B are displayed on the operation unit 252. The playback button 252A is operated when displaying the moving object log (the screen 270 (FIG. 15 described later)). The stop button 252B is operated when the acquisition of the sensor image 151 is finished. When the user operates the input unit 206 to select the playback button 252A, the input unit 206 receives an operation from the user, and supplies a moving body log display command to the moving body log module 230 according to the operation. In response to the instruction, the moving body log module 230 displays a moving body log screen 270 on the output unit 207 as shown in FIG.

  The screen 270 displays a recording result display unit 271 that displays a recording result based on the recording result information, a moving object log display unit 272 that displays a moving object log based on the moving object log information, and the number of moving objects generated in a predetermined management time zone. A moving object number graph display unit 273, a target time zone selection unit 274, a reproduction time selection unit 275, an OK button 276, a close button 277, and the like are included. The target time zone is a predetermined time zone (for example, 15 minutes) including the date and time of occurrence of the moving object corresponding to the zoom still image 272C to be displayed on the moving object log display unit 272.

  In the recording result display section 271, a date display section 271A and a target week selection section 271B are displayed. The date display unit 271 displays the date of the target week which is one week including the date of the target time zone. The target week selection unit 271B is operated when changing the target week.

  Based on the sensor flag and zoom flag of the recording record information, the moving object log module 230 sets the “sensor image 151 and the position of the date display unit 271A indicating the date and time corresponding to the record record information and the position of the time display unit 271C in the time. A color representing “no recording of the zoom image 152”, “there is only the sensor image 151”, or “there is both the sensor image 151 and the zoom image 152” is displayed. For example, “no recording of sensor image 151 and zoom image 152” is transparent, “only sensor image 151 is present” is light blue, and “both sensor image 151 and zoom image 152 are present” is blue. In FIG. 15, for example, light blue is displayed in the region 271C, and blue is displayed in the color display unit 271D.

  In this way, the user can display by color-coded “no sensor image 151 and zoom image 152 are recorded”, “sensor image 151 only”, or “sensor image 151 and zoom image 152 both”. Can easily determine whether or not the sensor image 151 or the zoom image 152 is recorded from the recording result display unit 271.

  In addition, the moving object log module 230 displays a color (for example, yellow) indicating the target time zone at the date in the date display unit 271A indicating the target time zone of the recording performance information and the position in the time of the time display unit 271C. Let In FIG. 15, yellow is displayed in the region 271E.

The moving object log display unit 272 displays a tab 272A and a thumbnail display unit 272B.
The tab 272A represents the number of pages of the moving object log display unit 272. The moving object log display unit 272 may display a scroll bar instead of the tab 272A so that the page to be displayed can be changed by the scroll bar. The thumbnail display unit 272B is displayed in, for example, a matrix on the moving object log display unit 272. The thumbnail display unit 272B displays, as a moving object log, a zoom still image 272C of a moving object generated in the target time zone and a zoom still image 272C. The time of occurrence of the corresponding moving object is displayed. The generation time displayed on the thumbnail display unit 272B is displayed in a different color for each camera ID of the sensor camera 121 that acquired the sensor image 151 corresponding to the generation time, for example.

  As described above, since only the zoom still image 272C of the moving object generated in the target time zone is displayed on the moving object log display unit 272, the user can easily search for the zoom still image 272C of the desired moving object.

  The moving object number graph display unit 273 displays a moving object number graph in which the horizontal axis represents the management time zone including the target time zone, and the vertical axis represents the number of moving bodies generated in the management time zone. Thus, by displaying the moving object number graph, the user can easily recognize the number of moving objects generated in the management time period without reproducing the sensor image 151. The moving object number graph display unit 273 also displays the maximum number of moving objects (26 in the example of FIG. 15) that occurred in the management time period including the target time period.

  The target time zone selection unit 274 is displayed when selecting a target time zone. The reproduction time selection unit 275 is displayed when selecting the occurrence date (time) of the moving object corresponding to the sensor image 151 or the zoom image 152 to be reproduced. The OK button 276 is operated when determining the time selected by the reproduction time selection unit 275. The close button 277 is operated when the display of the screen 270 is stopped.

As described above, since the recording result display unit 271, the moving object log display unit 272, and the moving object number graph display unit 273 are displayed on the screen 270, the user can change the time every one week including the target time zone. The presence / absence of recording of the sensor image 151 and the zoom image 152, the zoom still image 272C of the moving object generated in the target time zone, and the number of moving objects generated in the management time zone including the target time can be recognized simultaneously.

  In addition, the user can display the moving body log of the moving body generated at the desired date and time on the moving body log display section 272 by designating the position corresponding to the desired date and time on the recording result display section 271. As a result, it is possible to easily specify a desired date and time and display a moving body log of a moving object that occurred at the desired date and time, as compared with the case where the month, day, hour, and minute of the desired date and time are sequentially input.

  Further, for example, the user operates the input unit 206 to select a desired zoom still image 272C on the screen 270, thereby reproducing and displaying the desired sensor image 151 and the zoom image 152.

  For example, when the user designates a position in the area 271C of the recording result display unit 271, the screen 270 shown in FIG. 15 is changed to the screen 270 shown in FIG.

  In the region 271C, a light blue color indicating “there is only the sensor image 151” is displayed. That is, at the date and time corresponding to the region 271C, the zoom still image 272C is not acquired, and only the sensor image 151 is acquired. As shown in FIG. 16, the thumbnail display part 272 </ b> B is not displayed on the moving object log display part 272.

  When the user operates the input unit 206 to select the thumbnail display unit 272B on which the desired zoom still image 272C on the screen 270 in FIG. 15 is displayed, the moving body log module 230 displays the thumbnail display unit 272B. The generation date and time displayed on the playback module 231 is supplied. The reproduction module 231 reads the reproduction start position and moving object ID corresponding to the occurrence date and time from the moving object information DB 227 based on the occurrence date and time. The reproduction module 231 reproduces the sensor image 151 and the zoom image 152 from the display information DB 226 based on the read reproduction start position and moving object ID, and causes the output unit 207 to display the screen 300 shown in FIG. As described above, the user can designate the reproduction start position of the sensor image 151 by selecting the thumbnail display unit 272B.

  A screen 300 in FIG. 17 includes a sensor image display unit 251, a zoom image display unit 253, an operation unit 301 including a GUI for performing operations related to reproduction, and the like.

  The sensor image 151 reproduced from the display information DB 226 is displayed on the sensor image display unit 251, and the zoom image 152 reproduced from the display information DB 226 is displayed on the zoom image display unit 253.

  The operation unit 301 displays a live button 301A that is operated when the screen 270 illustrated in FIGS. 15 and 16 is displayed.

further,
FIG. 18 shows an example of the screen 270 displayed when the date display unit 271A is selected on the screen 270 of FIG. 15 or FIG.

  When the screen 270 in FIG. 15 or 16 is displayed and the user selects the date display unit 271A, the screen 270 in FIG. 15 or 16 is changed to the screen 270 shown in FIG. That is, a selection box 321 for selecting deletion or export of the sensor image 151 and the zoom image 152 is displayed. When the user selects to delete the selection box 321, the moving body log module 230 causes the output unit 207 to display a confirmation screen 340 illustrated in FIG. 19.

  As shown in FIG. 19, a message “Do you want to delete?”, An OK button 341, and a cancel button 342 are displayed on the confirmation screen 340. The OK button 341 is operated when instructing deletion. The cancel button 342 is operated when commanding cancellation (cancellation) of deletion.

  In FIG. 18, when the user selects the export in the selection box 321, a confirmation screen 340 similar to that in FIG. 19 is displayed on the output unit 207. In this case, the displayed message is a message “Do you want to export?”.

  Next, sensor image acquisition processing by the sensor image acquisition module 221 of FIG. 8 will be described with reference to FIG. This sensor image acquisition process is operated, for example, when the user instructs acquisition of the sensor image 151 by operating the input unit 206.

  In step S <b> 1, the sensor image acquisition module 221 requests the sensor camera 121 to acquire the sensor image 151. The camera unit 122A of the sensor camera 121 controls the pan / tilt unit 121A to shoot a wide area as a moving image with a predetermined shooting magnification while adjusting the horizontal or vertical direction of the shooting direction. Then, the camera unit 122A stores the sensor image 151, which is a moving image obtained as a result, in a client return buffer (not shown). In response to a request from the sensor image acquisition module 221, the sensor camera 121 supplies the sensor image 151 stored in the client return buffer and its own camera ID to the sensor image acquisition module 221.

  After step S1, the process proceeds to step S2, where the sensor image acquisition module 221 acquires the sensor image and camera ID from the sensor camera 121, and then proceeds to step S3. In step S3, the sensor image acquisition module 221 inputs the sensor image 151 from the sensor camera 121 to the moving body detection module 222, and proceeds to step S4.

  In step S4, the sensor image acquisition module 221 acquires the moving object ID, generation position, generation date and time, and reproduction start position of the moving object corresponding to the sensor image 151 input in step S3 from the moving object detection module 122, and the process proceeds to step S5. move on.

  In step S5, the sensor image acquisition module 221 performs the display information registration process of FIG. 21 in which the display position and the sensor image 151 are registered in the display information DB 226 using the moving object generation position as display information.

  After the process of step S5, the process proceeds to step S6, where the sensor image acquisition module 221 updates the client return buffer of the sensor camera 121, and proceeds to step S7. In step S7, it is determined whether there is no moving object disappeared from the sensor image 151, that is, whether the moving object ID and disappearance date / time of the moving object detected from the moving object detection module 222 are not supplied.

  If it is determined in step S7 that there is a moving object disappeared from the sensor image 151, the process proceeds to step S8, where the sensor image acquisition module 221 receives the moving object ID and disappearance time of the disappeared moving object supplied from the moving object detection module 222. The moving body information registration process of FIG. 22 registers the moving body information composed of the occurrence date and time, the generation position, the reproduction start position, and the camera ID supplied from the sensor camera 121 acquired in step S4 corresponding thereto in the moving body information DB 227. I do.

  If it is determined in step S7 that no moving object has disappeared from the sensor image 151, or after the process of step S8, the process proceeds to step S9, and the sensor image acquisition module 221 receives the sensor image 151 and the zoom image 152 from the input unit 206. Is determined, that is, whether the user has selected the stop button 252B by operating the input unit 206. If it is determined that the end is not requested, the process returns to step S1, Repeat the process.

  On the other hand, if it is determined in step S8 that the acquisition of the sensor image 151 and the zoom image 152 has been requested from the input unit 206, the process ends.

  Next, the display information registration process in step S5 in FIG. 20 will be described with reference to FIG.

  In step S21, the sensor image acquisition module 221 acquires date / time information representing the current date / time from the time measurement module 224, and the process proceeds to step S22. In step S <b> 22, the sensor image acquisition module 221 reads a sensor flag corresponding to the date and time indicated by the date and time information acquired in step S <b> 21 from the recording record information DB 229, and the sensor flag indicates 0 that the sensor image 151 is not recorded. It is determined whether or not.

  If it is determined in step S22 that the sensor flag is 0, the process proceeds to step S23, and the sensor image acquisition module 221 changes the sensor flag from 0 to 1 indicating that the sensor image 151 is recorded, Proceed to S24.

  On the other hand, if the sensor image acquisition module 221 determines in step S22 that the sensor flag is not 0, that is, the sensor flag is 1, the process skips step S23 and proceeds to step S24.

  In step S24, the sensor image acquisition module 221 acquires the number of frames of the sensor image 151 registered in the display information DB 226 file created in step S26 described later. In the first step S21, since a file has not yet been created in the display information DB 226, a file is created in the display information DB 226 without acquiring the number of frames. If a new file has not yet been created in step S26, the sensor image acquisition module 221 acquires the number of frames of the sensor image 151 registered in the file created in the first step S21.

  In step S25, the sensor image acquisition module 221 determines whether or not the number of frames acquired in step S24 has exceeded a predetermined threshold value set in advance by the user, for example. A new file is created in the information DB 226.

  If it is determined in step S25 that the number of frames acquired in step S24 does not exceed the predetermined threshold value, or after the processing in step S26, the process proceeds to step S27, and the sensor image acquisition module 221 is created in step S26. Display information is registered in the latest file of the displayed display information DB 226 in association with the sensor image 151. That is, in the display information DB 226, for each predetermined number of frames of the sensor image 151, display information corresponding to the sensor image 151 is stored as a file. Then, the process returns to step S5 in FIG. 20 and proceeds to step S6.

  As described above, since the display information corresponding to the sensor image 151 is stored as one file for each frame number of the sensor image 151, the reproduction module 231 can quickly search for the sensor image 151 to be reproduced. it can.

  With reference to FIG. 22, the moving body information registration process of step S8 of FIG. 20 will be described.

  In step S41, the sensor image acquisition module 221 determines whether there is no file in the moving object information DB 227 corresponding to the management time zone of the occurrence date and time acquired in step S4 of FIG. 20, that is, the management time zone of the occurrence date and time in step S42 described later. It is determined whether or not a file corresponding to is created, and if it is determined that there is a file corresponding to the management time zone of the occurrence date and time, the process proceeds to step S42.

  In step S42, the sensor image acquisition module 221 creates a file corresponding to the management time zone of the occurrence date and time. For example, when the occurrence date is 10:00 on January 10, 2004, a file corresponding to the management time zone from 10:00 to 11:00 on January 10, 2004 is created in the moving object information DB 227.

  On the other hand, when it is determined in step S41 that the file corresponding to the management time zone of the occurrence date / time is in the moving object information DB 227, step S42 is skipped and the process proceeds to step S43.

  In step S43, the sensor image acquisition module 221 registers the moving body information in the file corresponding to the management time zone of the occurrence date and time of the moving body information DB 227, returns to step S8 in FIG. 20, and proceeds to step S9.

Next, the moving object detection process by the moving object detection module 222 will be described with reference to FIG.
This moving object detection process is started when the sensor image 151 is supplied from the sensor image acquisition module 221 in step S3 of FIG.

  In step S <b> 61, the moving object detection module 222 determines whether the generation of a new moving object is detected from the sensor image 151 from the sensor image acquisition module 221. Specifically, the moving object detection module 222 obtains a difference value between the luminance levels of the sensor image 151 supplied from the sensor image acquisition module 221 and the sensor image 151 acquired immediately before. Then, when the difference value of the luminance level exceeds a threshold value set in advance by the manufacturer at the time of manufacture, the moving object detection module 222 detects a group of pixels constituting the sensor image 151 corresponding to the luminance level as a moving object. To do. Also, the moving object detection module 222 determines whether the detected moving object is a new moving object that has not been detected so far, based on, for example, the difference between the luminance levels and the collection of pixels detected as the moving object. judge.

  In step S61, when the occurrence of a new moving object is detected, the moving object detection module 222 assigns a moving object ID to the new moving object, and proceeds to step S62, where the moving object frame 172 is extracted from the collection of pixels detected as a moving object in step S61. The coordinates of the vertexes A to D of the moving object frame 172 are recognized as the generation position. The moving object detection module 222 recognizes the date and time when the moving object is detected in step S61 as the occurrence date and time based on the date and time information supplied from the time measuring module 224.

  Furthermore, the moving object detection module 222 recognizes the position from the top frame of the frame of the sensor image 151 that has detected the occurrence of a new moving object as the reproduction start position when reproducing the sensor image 151 corresponding to the moving object. The moving object detection module 222 supplies the sensor image acquisition module 221 with the moving object ID, the generation date and time, the generation position, and the reproduction start position of the new moving object that has been detected. The sensor image acquisition module 221 acquires the moving object ID, the generation date and time, the generation position, and the reproduction start position in step S4 of FIG.

  After the processing of step S62, the process proceeds to step S63, and the moving object detection module 222 stores the tracking object information including the moving object ID to which the detected moving object is assigned, the generation date and time, and the generation position in the tracking object information management DB 225. That is, the moving object detection module 222 updates the tracking target information management DB 225.

  Here, the moving object detection module 222 determines the priority order of the detected moving object for zoom shooting, and stores the tracking target information in the tracking target information management DB 225 in the descending order of priority.

  There are the following six methods for the moving body detection module 222 to determine the priority order.

  The first method is a method of determining the priority order so that the priority order of a moving object that is newly detected is higher than the priority order of a moving object that has already been detected. In this case, since the zoom image 152 of the moving object that is newly detected is preferentially acquired, for example, the zoom image 152 of the intruder can be easily acquired, and the intruder can be easily found.

  The second method is a method of determining the priority order so that the priority order of the moving object at the higher position is higher than the priority order of the moving object at the lower position. In this case, since the zoom image 152 of the moving body at a high position is preferentially acquired, it is generally easy to acquire zoom photography of a human face at a high position, and an intruder can be easily identified. it can.

  The third method is a method of determining the priority order so that the priority order of the moving object at the lower position is higher than the priority order of the moving object at the higher position. In this case, since the zoom image 152 of the moving object at a low position is preferentially acquired, when the sensor camera 121 is installed at a high position such as on an outdoor building, the sky or a high place such as a building. It becomes easier to acquire a zoom image 152 of a person or a vehicle that is relatively close to the vehicle.

  The fourth method is a method of determining the priority order so that the priority order of a moving object having a large size is higher than the priority order of a moving object having a small size. In this case, since the zoom image 152 of a large moving object is acquired preferentially, the zoom image 152 of the moving object in the vicinity is more easily acquired than the moving object located far away.

  The fifth method is a method of determining the priority order so that the priority order of the moving object having a small size is higher than the priority order of the moving object having a large size. In this case, since the zoom image 152 of a moving object with a small size is acquired with priority, the zoom image 152 of a moving object such as a person or a vehicle located far away is more easily acquired than a moving object in the vicinity.

  The sixth method is a method of determining the priority order so that the priority order of the vertically long moving object becomes higher. In this case, since the zoom image 152 of the vertically long moving object is preferentially acquired, it is easy to acquire the zoom image 152 of the whole human body that is generally a vertically long moving object.

  The method for determining the first to sixth priorities as described above can be selected by, for example, operating the input unit 206 by the user. The moving object detection module 222 determines the priority order of the detected moving object for zoom shooting according to any of the first to sixth methods selected by the user.

  After the process of step S63, the process proceeds to step S64, and the moving object detection module 222 determines whether there is a moving object that has disappeared on the sensor image 151 from the sensor image acquisition module 221. Specifically, the moving object detection module 222 detects in step S61 based on the difference value of the brightness level between the sensor image 151 supplied from the sensor image acquisition module 221 and the sensor image 151 acquired immediately before. However, it is determined whether there is a moving object that has disappeared from the sensor image 151 among moving objects that have not yet been detected to disappear.

  In step S64, if the sensor image acquisition module 221 determines that there is no disappearing moving object, the process returns to step S61 and repeats the above-described processing.

  If it is determined in step S64 that there is a disappeared moving object, the process proceeds to step S65, and the moving object detection module 222 recognizes the date and time represented by the date and time information as the disappearance date and time based on the date and time information from the timing module 224. Then, the disappearance date and time and the moving object ID of the disappearing moving object are supplied to the sensor image acquisition module 221 and the process returns to step S61.

  With reference to FIG. 24, zoom image acquisition processing by the tracking target image acquisition module 223 will be described. This zoom image acquisition process is started, for example, when the tracking target information management DB 225 is updated in step S63 of FIG.

  In step S81, the tracking target image acquisition module 223 acquires from the tracking target information management DB 225 the tracking target information of the moving body having the highest priority among the tracking target information stored in step S63, that is, the top tracking target information. To do. The tracking target information management DB 225 is updated when the tracking target information is acquired by the tracking target image acquisition module 223, and the tracking target information is deleted from the tracking target information management DB 225. That is, the top tracking target information in the tracking target information management DB always has the highest priority.

  After the processing of step S81, the process proceeds to step S82, and the tracking target image acquisition module 223 causes the zoom camera 122 to capture a region including the moving object generation position based on the moving object generation position of the tracking target information. Determine the position and size of the shooting angle of view. The tracking target image acquisition module 223 determines the shooting magnification from the change amount (moving speed of the moving object) and the size of the position of the shooting angle of view.

  After the process of step S82, the process proceeds to step S83, where the tracking target image acquisition module 223 determines the pan / tilt value from the change amount of the shooting field angle position and the position of the shooting field angle, and the process proceeds to step S84.

  In step S84, the tracking target image acquisition module 223 requests the zoom camera 122 to perform pan / tilt (movement) based on the pan / tilt value determined in step S83. In response to the request, the camera unit 122B of the zoom camera 122 controls the pan / tilt unit 122A to move itself to pan and tilt.

  After the process of step S84, the process proceeds to step S85, and the tracking target image acquisition module 223 requests the zoom camera 122 to perform zoom shooting based on the shooting magnification determined in step S82. The zoom camera 122 performs zoom shooting in response to the request, and supplies a zoom image 151 obtained as a result to the tracking target image acquisition module 223.

  After the process of step S85, the process proceeds to step S86, where the tracking target image acquisition module 223 acquires the zoom image 151 supplied from the zoom camera 122, and the process proceeds to step S87.

  In step S87, the tracking target image acquisition module 223 registers the zoom image 151 acquired in step S87 in the display information DB 226 as a predetermined file in association with the moving object ID of the tracking target information acquired in step S81.

  After the processing in step S87, the process proceeds to step S88, and the tracking target image acquisition module 223 includes the moving object ID of the tracking target information acquired in step S81 and the zoom still image 272C obtained by capturing the zoom image 151 at a predetermined timing. The moving body log information registration processing of FIG. 25 for registering the moving body log information in the moving body log information DB 228 is performed, and the process returns to step S81.

  With reference to FIG. 25, the moving body log information registration process of step S88 of FIG. 24 is demonstrated.

  In step S101, the tracking target image acquisition module 223 acquires date / time information representing the current date / time from the time measurement module 224, and the process proceeds to step S102.

  In step S102, the tracking target image acquisition module 223 creates a file created in step S103, which will be described later, corresponding to the management time zone including the current date and time in the moving body log information DB 228 based on the date and time information acquired in step S101. It is determined whether or not is stored.

  If it is determined in step S103 that the moving body log information DB 228 does not store a file corresponding to the management time zone including the current date and time, the process proceeds to step S103, and the tracking target image acquisition module 223 displays the current date and time. A file corresponding to the management time zone is created and stored in the moving object log information DB 228, and the process proceeds to step S104.

  On the other hand, if it is determined in step S102 that the moving body log information DB 228 stores a file corresponding to the management time zone including the current date and time, the process skips step S103 and proceeds to step S104.

  In step S104, the tracking target image acquisition module 223 captures the moving object ID of the tracking target information acquired in step S81 of FIG. 24 and the zoom image 152 acquired in step S86 at a predetermined timing in the moving object log information DB 228. The moving body log information including the still image 272C is registered. As described above, since the zoom still image 272C is registered separately from the moving body information, the capacity of the data stored in the moving body information DB 227 can be reduced, and predetermined moving body information can be quickly searched from the moving body information DB 227. it can.

  After the processing in step S104, the process proceeds to step S105, and the tracking target image acquisition module 223 zooms in the recording performance information corresponding to the management time zone including the date and time represented by the date and time information acquired in step S101 in the recording performance information DB 229. Is 0 indicating that the zoom image 152 is not recorded.

  If it is determined in step S105 that the zoom flag of the recording record information is 0, the process proceeds to step S106, and the tracking target image acquisition module 223 changes the zoom flag to 1 indicating that the zoom image 152 is recorded. Return to step S88 in FIG.

  On the other hand, if it is determined in step S105 that the zoom flag of the recording record information is not “0”, that is, the zoom flag is “1”, the process ends.

  Next, with reference to FIG. 26, the display processing of the screen 270 of FIG. 15 and FIG. 16 by the moving body log module 230 of FIG. 8 will be described. In this display process, for example, the user operates the input unit 206 to select the playback button 252A in FIG. 14 or the live button 301A in FIG. 17, and a command for displaying a moving body log is issued from the input unit 206 according to the operation. Started when supplied.

  In step S121, the moving object log module 230 performs a recording result information screen display process of FIG. 28 described later for displaying the recording result display unit 271 of FIG. 15, and proceeds to step S122.

  In step S122, the moving body log module 230 performs a moving body number graph display process of FIG. 29 described later for displaying the moving body log display unit 272 moving body number graph 273 of FIG. 15, and the process proceeds to step S123.

  In step S123, the moving body log module 230 reads the file corresponding to the target time zone from the moving body information DB 227, and based on the number of moving bodies corresponding to the moving body information registered in the file, the page represented by the tab 272A. Find a number. Specifically, the moving body log module 230 uses the number of moving bodies corresponding to the moving body information registered in the file read from the moving body information DB 227 to display the thumbnail display section 272B that can be displayed at a time on the moving body log display section 272. A value obtained by dividing the number Kmax (for example, Kmax = 7 × 5 = 35 in the example of FIG. 15), that is, the number Kmax of the thumbnail display unit 272B that can be displayed on one page of the moving object log display unit 272, Ask. Note that the value after the decimal point is incremented.

  In step S124, the moving body log module 230 sets the display page number N, which is the page number of the moving body log display unit 272 to be displayed, to 1. That is, the first page of the moving object log display unit 272 is displayed on the screen 270. After the process of step S124, it progresses to step S125, and the moving body log module 230 sets the display count value K to 0, and progresses to step S126.

  In step S126, the moving body log module 230 performs a moving body log display unit display process of FIG. 30 to be described later for displaying the moving body log display unit 272 of the screen 270, and proceeds to step S127.

  In step S127, the moving body log module 230 determines whether or not the moving body log display unit 272 is instructed by the user, that is, instruction information representing an instruction of the moving body log display unit 272 is supplied from the input unit 206 according to the user's operation. Determine if. While viewing the moving object log display unit 272, the user instructs the thumbnail display unit 272B on which the zoomed still image 272C of the desired moving object is displayed, thereby instructing the reproduction of the sensor image 151 and the zoom image 152 including the moving object. To do.

  If it is determined in step S127 that the moving object log display unit 272 has been instructed by the user, the process proceeds to step S128, and the moving object log module 230 recognizes the coordinates on the moving object log display unit 272 at the position instructed by the user.

  In step S129, the moving object log module 230 determines whether the position designated by the user is in the thumbnail display unit 272B based on the coordinates of the position designated by the user recognized in step S128, that is, the user displays the thumbnail display unit 272B. It is determined whether any one of the above is designated.

  If it is determined in step S129 that the position instructed by the user is not in the thumbnail display unit 272B, the process returns to step S127.

  On the other hand, if it is determined in step S129 that the position instructed by the user is in the thumbnail display unit 272B, the process proceeds to step S130, and the moving body log module 230 displays the zoom still image displayed in the thumbnail display unit 272B. The date and time of occurrence of 272C is output to the playback module 231 and the process is terminated. Specifically, on the screen 270 of FIG. 15, when the user operates the input unit 206 to indicate a position in the thumbnail display unit 272B, the moving body log module 230 is displayed in the thumbnail display unit 272B. The moving object ID corresponding to the zoom still image 272C is read from the moving object log information DB 228. Then, the moving object log module 230 reads out the generation date and time of moving object information corresponding to the moving object ID, outputs it to the playback module 231, and ends the processing.

  If it is determined in step S127 that the moving body log display unit 272 is not instructed by the user, the process proceeds to step S131, and the moving body log module 230 determines whether or not the tab 272A is selected by the user. Specifically, when changing the page of the moving body log display unit 272 displayed on the screen 270, the user operates the input unit 206 and selects a tab 272A representing a desired page number Nc. In response to the operation, the input unit 206 supplies a command for changing the display page number N to the page number Nc to the moving object log display unit 272. The moving object log display unit 272 determines whether a command for changing the display page number N to the page number Nc is supplied from the input unit 206.

  In step S131, when the user selects the tab 272A, that is, when an instruction to change the display page number N to the page number Nc is supplied from the input unit 206, the process proceeds to step S132, and the display page number N is changed to the user's page number Nc. A desired page number Nc is set.

  After the process of step S132, the process proceeds to step S133, the moving body log module 230 sets the display count value K to 0, returns to step S126, and the display of the moving body log display unit 272 is updated.

  On the other hand, if the user does not select the tab 272A in step S131, that is, if the command to change the display page number N to the page number Nc is not supplied from the input unit 206, the process proceeds to step S134, and the moving body log module 230 is performed. Determines whether the target time zone has changed.

  Specifically, when changing the target time zone, the user operates the input unit 206 (for example, the up and down arrow keys on the keyboard) to indicate the position corresponding to the desired target time zone in the recording performance display unit 271. Or operating the target time zone selection unit 274 to select a desired target time zone. At this time, the input unit 206 supplies a command to change the target time zone to the moving body log module 230 in accordance with an operation from the user. The moving object log module 230 determines whether a command for changing the target time zone is supplied from the input unit 206.

  In step S134, when the target time zone is changed, that is, when a command for changing the target time zone is supplied from the input unit 206, the moving body log module 230 displays the date display unit indicating the target time zone of the recording performance display unit 271. The color of the position of the date of 271A and the time of the time display unit 271C is changed to a predetermined color (for example, yellow), the process returns to step S126, and the display of the moving object log display unit 272 is updated.

  In step S134, if the target time zone has not been changed, that is, if the command for changing the target time zone has not been supplied from the input unit 206, the process proceeds to step S135, and the moving body log module 230 changes the target week. Determine whether or not.

  Specifically, when changing the target week, the user operates the input unit 206 and operates the target week selection unit 271B of the recording performance display unit 271 in FIG. 15 to select a desired target week. At this time, the input unit 206 supplies a command for changing the target week to the moving body log module 230 in accordance with an operation from the user. The moving object log module 230 determines whether a command for changing the target week is supplied from the input unit 206. When the date displayed on the date display unit 271A is the date of the current week, when the user operates the target week selection unit 271B and selects the next week as the target week, the operation is invalid. Become.

  In step S135, when the target week is changed, that is, when the command for changing the target week is supplied from the input unit 206, the moving body log module 230 returns to step S121 and repeats the above-described processing.

  On the other hand, if the target week is not changed in step S135, that is, if the command for changing the target week is not supplied from the input unit 206, the process proceeds to step S136 in FIG. 27 to determine whether the OK button 276 has been operated. To do.

  Specifically, when the user determines the occurrence date and time of the moving object corresponding to the sensor image 151 and the zoom image 152 to be reproduced, the user operates the input unit 206 and operates the reproduction time selection unit 275, Select the occurrence date and time. Thereafter, the user operates the input unit 206 and operates the OK button 276. At this time, the input unit 206 supplies information representing the operation of the OK button 276 to the moving body log module 230 according to the operation from the user, and the moving body log module 230 represents the operation of the OK button 276 from the input unit 206. Determine if information has been supplied.

  If the OK button 276 is not operated in step S136, that is, if the information indicating the operation of the OK button 276 is not supplied from the input unit 206, the process returns to step S127, and the moving object log module 230 repeats the above-described processing.

  If the OK button 276 is operated in step S136, that is, if the information indicating the operation of the OK button 276 is supplied from the input unit 206, the process proceeds to step S137, and the moving object log module 230 is generated from the moving object information DB 227. As the date and time, the time of the occurrence date and time selected by the user (17:30 in the example of FIG. 15) and the date corresponding to the area 271E of the recording performance display unit 271 (January 13, 2005 in the example of FIG. 5) The moving object information including “day” is read out and output to the reproduction module 231.

  After the process of step S137, the process proceeds to step S138, and the moving body log module 230 receives information indicating the operation of the close button 277 from the input unit 205 according to whether the close button 277 has been operated by the user, that is, according to the user's operation. Determine if it was supplied.

  In step S138, when the close button 277 is not operated by the user, the process returns to step S127 and the above-described processing is repeated. On the other hand, when the close button 277 is operated in step S138, the moving body log module 230 stops displaying the screen 270 and ends the process.

  Next, with reference to FIG. 28, the recording performance information screen display process in step S121 of FIG. 26 will be described.

  In step S151, the moving body log module 230 sets the target week to the target week changed in step S135 of FIG. In the first step S151, the moving object log module 230, for example, when the user operates the playback button 252A of FIG. 14 or the live button 301A of FIG. 17 based on the date / time information supplied from the time measuring module 224. And a predetermined time including the date is set as the target time zone. Also, the moving object log module 230 sets one week including the date as the target week.

  When the live button 301A is operated by the user, the moving object log module 230 displays the sensor image 151 and the zoom image 152 displayed on the sensor image display unit 251 and the zoom image display unit 253 (FIG. 17) at that time. It is also possible to set a predetermined time including the occurrence date and time of the moving object corresponding to the target time zone and set one week including the occurrence date as the target week.

  After the processing in step S151, the process proceeds to step S152, and the moving body log module 230 displays the target week set in step S151 on the date display unit 271A, and the process proceeds to step S153. In step S153, the moving object log module 230 acquires the recording record information of the target week from the recording record information DB 229, and proceeds to step S154.

  In step S154, the moving object log module 230 causes the recording record display unit 271 to display a recording record indicating the presence / absence of recording (recording) of the sensor image 151 and the zoom image 152 based on the recording record information acquired in step S153. . Specifically, the moving object log module 230 is based on the date of the date display unit 271A indicating the date and time corresponding to the recording record information and the position of the time display unit 271C in the time based on the sensor flag and zoom flag of the recording record information. “No recording of sensor image 151 and zoom image 152” is transparent, “only sensor image 151 is present” is light blue, and “both sensor image 151 and zoom image 152 are present” is blue.

  After the processing of step S154, the process proceeds to step S155, and the moving body log module 230 displays the target time zone on the target time zone selection unit 274 and the date display unit 271A representing the target time zone of the recording performance display unit 271. The color of the position of the date and time display unit 271C in the time is changed to a predetermined color (for example, yellow).

  After the process of step S155, it progresses to step S156 and the moving body log module 230 displays the reproduction | regeneration time selection part 275. FIG. For example, the reproduction time selection unit 275 displays the first time in the target time zone.

  After the processing of step S156, the process proceeds to step S157, and the moving object log module 230 displays the OK button 276 and the close button 277, returns to step S121 in FIG. 26, and proceeds to step S122.

  Next, with reference to FIG. 29, the moving object number graph display process of step S122 of FIG. 26 will be described.

  In step S171, the moving body log module 230 acquires the moving body information of the management time zone including the target time zone from the moving body information DB 227, and proceeds to step S172.

  In step S172, the moving object log module 230 obtains the maximum number of moving objects generated per minute based on the moving object information acquired in step S171. For example, when the moving object information in FIG. 10 is acquired, one moving object is generated at 10 o'clock and 10: 5, so the maximum number of moving objects generated per minute is one.

  After the process of step S172, the process proceeds to step S173, and the moving object log module 230 obtains the ratio of the number of moving objects generated every minute and the maximum number of moving objects obtained in step S172 every minute, Proceed to step S174.

  In step S174, the moving body log module 230 determines that the horizontal axis indicates the management time zone based on the management time zone, the maximum number of moving bodies obtained in step S172, and the ratio obtained in step S173. , A moving object number graph in which the vertical axis represents the number of moving objects is displayed. For example, if the maximum number of moving objects obtained in step S172 is 26, the moving object log module 230 sets the maximum value of the vertical axis of the moving object number graph to 26 as shown in FIG. Every minute, a bar having a height corresponding to the ratio obtained in step S173 is displayed as a moving object number graph. In addition, you may make it display the bar | burr corresponding to all the generation | occurrence | production time currently displayed on the thumbnail display part 272B by the color different from another bar | burr. Thus, the user can easily recognize where the zoom still image 272C displayed on the thumbnail display unit 272B is located in the moving object number graph. After the process of step S174, the process returns to step S122 of FIG. 26, and the process proceeds to step S123.

  Next, the moving body log display unit display process in step S126 of FIG. 26 will be described with reference to FIG.

  In step S191, the moving body log module 230 acquires the moving body information of the target time zone from the moving body information DB 227, and whether the moving body information includes the M (= Kmax × (N−1) + K + 1) th moving body information from the top. Determine if.

  If it is determined in step S191 that there is the Mth moving body information from the beginning, the process proceeds to step S192, and the moving body log module 230 stores the moving body log information corresponding to the moving body ID included in the moving body information, as the moving body log information DB 228. The zoom still image 272C of the moving object log information is selected as a display target of the thumbnail display unit 272B.

  After the processing in step S192, the process proceeds to step S193, and the moving body log module 230 determines the thumbnail display unit 272B that displays the display target selected in step S192, based on the display count value K. For example, in the thumbnail display portion 272B, a display count value K corresponding to the zoom still image 272C displayed thereon is preset by the user. For example, the user sets the display count value K to increase in the lower right direction sequentially from the upper left thumbnail display portion 272B of the moving object log display portion 272. In this case, as shown in FIG. 15, when seven thumbnail display portions 272B are arranged in the horizontal direction of the moving object log display portion 272, when the display count value K is set to 2, from the top left The second thumbnail display unit 272B is determined as the thumbnail display unit 272B that displays the display target.

  After the process of step S193, the process proceeds to step S194, and the moving body log module 230 displays the zoom still image 272C to be displayed on the thumbnail display unit 272B determined in step S193. If there is no corresponding moving body log information in the moving body log information DB 228, nothing is displayed on the thumbnail display unit 272B determined in step S193.

  After the process of step S194, the process proceeds to step S195, and the moving object log module 230 determines the display color of the occurrence date and time based on the camera ID of the Mth moving object information from the top of the moving object information acquired in step S191. To do. For example, the moving object log module 230 determines a different display color for each camera ID.

  After the processing of step S195, the process proceeds to step S196, and the moving body log module 230 uses the time of occurrence of the Mth moving body information from the beginning of the moving body information acquired in step S191 as the occurrence date and time, as a thumbnail display unit. In 272B, the display color determined in step S195 is displayed.

  After the process of step S196, the process proceeds to step S197, and the moving object log module 230 determines whether or not the display count value K is smaller than the number Kmax of thumbnail display parts 272B that can be displayed on the moving object log display part 272 at a time. If it is determined that it is small, the process proceeds to step S198.

  In step S198, the moving body log module 230 increments the display count value K by 1, returns to step S191, and repeats the above-described processing.

  If it is determined in step S191 that there is no M-th moving body information from the top, or if the display count value K is smaller than the number Kmax of thumbnail display sections 272B that can be displayed at one time on the moving body log display section 272 in step S197. If it is determined that there is not, the process returns to step S126 of FIG. 26, and the process proceeds to step S127.

  Next, with reference to FIG. 31, the reproduction process of the sensor image 151 and the zoom image 152 by the reproduction module 231 in FIG. 8 will be described. This reproduction process is started, for example, when the moving object generation date and time corresponding to the sensor image 151 and the zoom image 152 to be reproduced is supplied from the moving object log module 230 in step S130 of FIG. 26 or S137 of FIG. The At this time, the playback module 231 displays the screen 300 of FIG.

  In step S211, the reproduction module 231 reads from the moving body log DB 227 a file corresponding to the management time zone including the occurrence date and time supplied from the moving body log module 230, and the moving body including the occurrence date and time registered in the file. The reproduction start position and moving object ID are acquired from the information.

  After the processing in step S211, the process proceeds to step S212, and the playback module 231 reads from the display information DB 226 the sensor image 151 after the playback start position and the moving body based on the playback start position and the moving body ID acquired in step S211. The zoom image 152 associated with the ID is sequentially reproduced and displayed on the sensor image display unit 251 (FIG. 17) and the zoom image display unit 253, respectively, and the process ends.

  Next, editing processing of the sensor image 151 and the zoom image 152 by the client 132 will be described with reference to FIG. This editing process is started, for example, when the user operates the input unit 206 and selects the date display unit 271A in FIG.

  In step S231, the moving object log module 230 acquires the date of the date display unit 271A selected by the user according to the information representing the selection of the date display unit 271A supplied from the input unit 206 according to the user's operation, The process proceeds to step S232.

  In step S232, the moving object log module 230 determines whether the date acquired in step S231 is before the current date based on the date / time information from the timing module 224, and determines that the date is not before the current date. If YES, go to step S233.

  In step S233, the moving object log module 230 displays an error message indicating that it cannot be deleted or exported, and ends the process.

  On the other hand, in step S234, the moving object log module 230 determines whether there is a sensor image 151 or zoom image 152 of the date acquired in step S231. Specifically, the moving body log module 230 reads all the recording performance information corresponding to the management time zone of the date acquired in step S231 from the recording performance information DB 229, and at least one sensor flag or zoom of the recording performance information. It is determined whether or not the flag is “1”.

  If it is determined in step S234 that there is no sensor image 151 or zoom image 152, the process proceeds to step S233 and the above-described processing is performed.

  If it is determined in step S234 that there is a sensor image 151 or zoom image 152, the process proceeds to step S235, the selection box 321 for selecting deletion or export in FIG. 18 is displayed, and the process proceeds to step S236.

  In step S236, the moving object log module 230 determines whether to delete the sensor image 151 or the zoom image 152, that is, whether the user has selected to delete the selection box 321 by operating the input unit 206.

  If the sensor image 151 or the zoom image 152 is not deleted in step S236, that is, if the user selects the export of the selection box 321 by operating the input unit 206, the process proceeds to step S237, and the moving body log module 230 A folder selection screen for selecting the destination folder is displayed. The user operates the input unit 206 to select a desired folder as an export destination from the folder selection screen.

  After the processing of step S237, the process proceeds to step S238, and the moving body log module 230 determines whether or not the sensor image 151 or the zoom image 152 can be exported to the folder selected by the user, and can export it. If it is determined that it cannot be performed, the process proceeds to step S239.

  In step S239, the moving object log module 230 displays an error message indicating that it cannot be exported, and the process returns to step S237.

  On the other hand, when it is determined in step S238 that the sensor image 151 or the zoom image 152 can be exported to the folder selected by the user, the process proceeds to step S240, and the moving body log module 230 determines whether or not to export. A confirmation screen 340 (FIG. 19) for confirmation is displayed, and the process proceeds to step S241.

  In step S241, the moving body log module 230 determines whether or not the user has operated the OK button 341. If the moving body log module 230 determines that the OK button 341 has been operated, the process proceeds to step S242, and the date acquired in step S231 and step S237. Then, the export destination selected in step S3 is supplied to the playback module 231. Based on the date from the moving body log module 230, the playback module 231 reads a file corresponding to the management time zone of the date from the moving body information DB 227, and recognizes the playback start position and the moving body ID registered in the file. . Based on the reproduction start position and the moving object ID, the reproduction module 231 reproduces the sensor image 151 corresponding to the reproduction start position and the zoom image 152 corresponding to the moving object ID from the display information DB 226 and exports them. To export and finish the process.

  If it is determined in step S241 that the OK button 341 has not been operated, that is, the cancel button 342 has been operated, step S242 is skipped and the process ends.

  In step S236, when the sensor image 151 or the zoom image 152 is deleted, that is, when the user selects deletion of the selection box 321 by operating the input unit 206, the process proceeds to step S244, and the moving object log module 230 performs step S241 and step S241. Similarly, a confirmation screen 340 (FIG. 19) for confirming whether to delete is displayed, and the process proceeds to step S244.

  In step S244, the moving body log module 230 determines whether or not the OK button 341 has been operated by the user in the same manner as in step S241. If it is determined that the OK button 341 has been operated, the process proceeds to step S245, and is acquired in step S231. The date thus recorded is supplied to the reproduction module 231. Based on the date from the moving body log module 230, the playback module 231 reads a file corresponding to the management time zone of the date from the moving body information DB 227, and recognizes the playback start position and the moving body ID registered in the file. . Based on the reproduction start position and moving object ID, the reproduction module 231 deletes the sensor image 151 corresponding to the reproduction start position and the zoom image 152 corresponding to the moving object ID from the display information DB 226 and ends the process. To do.

  If it is determined in step S244 that the OK button 341 has not been operated, that is, the cancel button 342 has been operated, step S245 is skipped and the process ends.

  In the present embodiment, deletion or export is performed as the editing process. However, the present invention is not limited to this. For example, the sensor image 151 or the zoom image 152 may be compressed. Further, although the editing process is performed for each date selected by the user, the editing process may be performed for each date and time by allowing the user to select a time.

  In the above description, the monitoring system 10 records the sensor image 151 and the zoom image 152, but may record only the zoom image 152 without recording the sensor image 151. In addition, the user may operate the input unit 206 to select either the full recording mode in which the sensor image 151 and the zoom image 152 are recorded, or the zoom image only recording mode in which only the zoom image 152 is recorded. .

  The sensor image acquisition process by the sensor image acquisition module 221 in this case will be described with reference to FIG.

  The processing in steps S251 through S254 is the same as the processing in steps S1 through S4 in FIG.

  After the process of step S254, the process proceeds to step S255, and the sensor image acquisition module 221 determines whether or not the recording mode is the zoom image only recording mode. Specifically, the input unit 206 supplies the sensor image acquisition module 221 with information indicating selection of the all recording mode or the zoom image only recording mode in accordance with an operation from the user. The sensor image acquisition module 221 sets the recording mode to the all recording mode or the zoom image only recording mode in accordance with the information. In step S255, the sensor image acquisition module 221 determines whether or not the currently set recording mode is a zoom image only recording mode.

  If the sensor image acquisition module 221 determines in step S255 that the recording mode is not the zoom image only recording mode, that is, the recording mode is the full recording mode, the process proceeds to step S256.

  On the other hand, when the sensor image acquisition module 221 determines in step S255 that the recording mode is the zoom image only recording mode, the process skips step S256 and proceeds to step S257. That is, the sensor image acquisition module 221 does not record the sensor image 151 in the display information DB 226, and the sensor flag of the recording performance information in the recording performance information DB 229 remains 0 indicating that the sensor image 151 is not recorded.

  The processing in steps 256 to S260 is the same as the processing in steps S5 to S9 in FIG.

  Next, the storage capacity of data stored in the display information DB 226 when the recording mode is the zoom image only recording mode will be described with reference to FIG.

  As shown in FIG. 34, the display information DB 226 records only the zoom image 152 acquired by the zoom camera 122 only when the occurrence of a moving object is detected. Therefore, compared with the case where both the sensor image 151 and the zoom image 152 shown in FIG. 13 are recorded, the capacity of data recorded in the display information DB 226 can be further reduced.

  Note that only the moving object sensor image 151 and the zoom image 152 whose priority order is, for example, a threshold set in advance by the user or more based on the priority order of the moving object corresponding to the sensor image 151 and the zoom image 152 are recorded. You may be made to do. Further, based on the priority order, only the zoom image 152 of the moving object whose priority order is equal to or higher than the threshold may be recorded.

  Further, the size of the moving object detected by the moving object detection module 222 described above may be set by the user operating the input unit 206.

  In this case, the user operates the input unit 206 to cause the output unit 207 to display a screen 401 for setting the size of the moving object, as shown in FIG.

  As shown in FIG. 35, the text box 411A or the slider 412A is operated when setting the minimum horizontal size (X direction) (pixels) of the moving object detected by the sensor camera 121. The user operates the text box 411A to input a numerical value, or operates the slider 412A to move in the horizontal direction in the figure to set the minimum horizontal size of the moving object.

  The text box 411 </ b> B or the slider 412 </ b> B is operated when setting the minimum vertical size (Y direction) size (pixels) of the moving object detected by the sensor camera 121. The text box 413A or the slider 414A is operated to set the maximum horizontal size of the moving object detected by the sensor camera 121, and the text box 413B or the slider 414B is operated to set the maximum vertical size.

  The test button 415 is operated when visually comparing the set maximum and minimum sizes of moving objects with the size of the subject in the sensor image 151. When the test button 415 is operated by the user, a screen 421 as shown in FIG. 36 is displayed on the output unit 207.

  As shown in FIG. 36, on the screen 421, for example, a sensor image display unit 430 that displays the sensor image 151, a maximum size unit 431 that displays the maximum size of the moving object that is currently set, and a moving object that is the detection object A minimum size portion 432 for displaying the minimum size of the image is displayed.

  For example, the user visually compares the person 433 of the sensor image 151 displayed on the sensor image display unit 430 with the maximum size unit 431 and the minimum size unit 432, so that the user can set the moving object set by the user himself / herself. It is easy to check whether the maximum and minimum sizes of are reasonable values.

  FIG. 37 shows a configuration example of another embodiment of the monitoring system 101 of FIG. In addition, the same code | symbol is attached | subjected to the same thing as FIG. The same applies to FIG. 38 described later.

  FIG. 38 shows a configuration example of still another embodiment of the monitoring system 101.

  In the monitoring system 101 of FIG. 38, a fixed camera 471 is further connected to the network 131. In this case, the moving object detection module 222 of the client 132 also detects a moving object in a fixed image that is a moving image obtained as a result of shooting by the fixed camera 471, and the moving object log module 230 displays the thumbnail display unit 272B (FIG. 15) of the screen 270. ) Display a still image obtained by capturing a fixed image corresponding to a moving object at a predetermined timing. At this time, the display color (for example, green or yellow) of the occurrence date and time displayed on the thumbnail display unit 272 is the display color (for example, white) of the occurrence date and time corresponding to the sensor image 151 acquired by the sensor camera 121. It may be different. When the user designates a still image displayed on the thumbnail display unit 272 </ b> B, a fixed image corresponding to the still image is reproduced and displayed on the output unit 207.

  As described above, since the monitoring system 101 in FIG. 38 detects not only the sensor image 151 but also the moving object in the fixed image, the monitoring area can be increased. For example, a fixed camera 471 is installed to monitor a fixed area where a lot of moving objects such as a parking lot tollgate and an entrance / exit (gate) are generated, and a camera unit 111 is installed to monitor a wide area in the parking lot. This makes it possible to reliably monitor the entire parking lot.

  Each block of the client 132 in FIG. 8 may be provided in the sensor camera 121 or the zoom camera 122 instead of the client 132.

  Further, the use of the monitoring system 101 is not limited to monitoring the area 21.

  Further, the sensor camera 121 and the zoom camera 122 are not limited to pan / tilt cameras.

For example, the sensor image 151 is formed by one camera. And the zoom image 152 may be acquired.

  Further, in the present embodiment, the display color of the occurrence date and time displayed on the thumbnail display unit 272 is determined based on the camera ID of the sensor camera 121, but is determined based on the camera ID of the zoom camera 122. It is good to be done. In this case, the camera ID of the zoom camera 122 is also registered in the moving object log information DB 228 as moving object log information.

  As described above, in the monitoring system 101, the zoom image 152 associated with the moving object ID and the reproduction start position associated with the moving object ID are stored separately in the moving object log information DB 228 and the moving object information DB 227, respectively. When the zoom image 152 corresponding to the target sensor image 151 is designated, the moving body ID corresponding to the zoom image 152 is read (searched) from the moving body log information DB 228 having a smaller number of data than the moving body information DB 227, and The reproduction start position corresponding to the moving object ID can be read from the moving object information DB 227, and the sensor image 151 stored in the display information DB 226 can be reproduced based on the reproduction start position. As a result, the sensor image 151 desired by the user can be easily reproduced.

  Further, the monitoring system 101 can detect a moving object in the area 21 based on the sensor image 151 of the wide area 21 obtained as a result of imaging by the sensor camera 121, and image the moving object by the zoom camera 122. it can.
