From this image 2, the background (outside the wall k) of the original image 1 in FIG. 6A is erased so that an image 3 in which an intruder appears (see FIG. 6C) is obtained. It has become. Then, from this image 3, narrow regions 4a and 4b including two objects (people) x and y are left, and other regions are erased (mask processing) to obtain image 4 (see FIG. 6D).

  Next, the image 5 (see FIG. 6E) in which the area 5a (solid color display) to be monitored is left and the other non-monitored areas are erased (mask processing) is superimposed on the image 4. As a result, an image 6 (see FIG. 6F) displaying only the portion of the narrow area 4a including the intruder x is obtained. Therefore, it is specified that the intruder x exists in the area 4a. In addition, for the intruder x present in the specified area 4a, the supervisor confirms the image displayed on the video monitor (equivalent to the image in FIG. 6F), and the intruder x is a human. Judging whether there is.

Next, a step of confirming whether or not the previous determination result is a correct determination is provided. That is, it is confirmed whether the intruder is actually a person or an animal, and it is determined whether or not the background image mask processing is performed by performing an input operation of the correct detection (correct detection). In particular, when an intruder is not correctly determined, a masking process (not captured as data) is performed for the area that has not been correctly determined.

  Embodiments of an intruder image monitoring system according to the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a schematic diagram showing an embodiment of an intruder image monitoring system 20 according to the present invention.

  The intruder image monitoring system 20 is a system for more accurately detecting an intruder monitoring object to the intruder monitoring area z by a monitoring camera, for example, a video camera 21. This intruder image monitoring system 20 includes an image monitoring device 22 installed in or near the intruder monitoring area z, and an intrusion installed in a place away from the image monitoring device 22, for example, a monitoring center (not shown). An object monitoring device 23, and a communication line 24 such as a LAN for communication connection between the video monitoring device 22 and the intruder monitoring device 23.

  As shown in FIGS. 2 (a) and 2 (b), the intruder image monitoring system 20 is a surveillance camera such as a video camera 21 when it enters an intruder monitoring area z such as an area where people are prohibited or dangerous. When the monitoring object is detected and a monitoring object such as a person is detected, an alarm is issued to the monitoring person side. When an alarm is issued, the image data a captured by the video camera 21 is stored, and on the basis of the stored image data a, as shown in FIG. 3, the image data table 30 and FIG. Thus, it is provided so that it can be processed into the parameter graph 31 and transmitted to the intruder monitoring device 23 side.

  The communication line 24 receives an alarm signal x1, an object video image data signal (hereinafter referred to as an image data signal) x2, a parameter data signal x3 and a monitor data signal x4 transmitted from the video monitoring device 22 side, and an intruder. This is a line through which an object video image data request signal (hereinafter referred to as a data request signal) y1 and a parameter information registration signal y2 output from the monitoring device 23 side.

  The video monitoring device 22 is suitable for monitoring the intruder monitoring area z, for example, a video monitoring panel 26 installed in a monitoring building (not shown) near the site, and can capture an intruder image in the vicinity of the site. A surveillance camera, for example, a video camera 21 installed at the position is provided. The video camera 21 can acquire data on the size and staying time of an object that enters the intruder monitoring area z (staying time of an object moving within the monitor screen).

  As shown in FIG. 2A, for example, the video of the monitoring object acquired by the video camera 21 is a case of a person who can see a substantially linear regular movement pattern in the direction of the arrow e. As shown in FIG. 2 (b), the case of an animal such as a dog / cat, in which an irregular movement pattern is seen in the direction of the arrow f is assumed.

  The video monitoring board 26 includes an alarm signal transmitter 27 and an object video image data generation means (hereinafter referred to as image data generation means) 28.

  The video surveillance panel 26 determines the situation such as the size of the intruder, the movement trajectory, and the staying time (the time during which the intruder stayed in the screen) from the image data a captured by the video camera 21. If the intruder is a monitoring target, for example, whether it is a person or not, and if it is determined that it is a person, the video image data of the monitoring target can be easily monitored on the monitor side. The screen format is processed. Examples of processing of the image data a include an image data table 30 for each image data (by object video image data No) and data detection items as shown in FIG. 3, and image data as shown in FIG. It is the parameter graph 31 which shows the stay time characteristic and detection size characteristic which are produced based on Table 30 separately on the same screen.

  The video monitoring board 26 will be specifically described.

  When the video camera 21 acquires the image data a that substantially matches the assumed object image in the intruder monitoring area z, the alarm signal transmitter 27 monitors the image data of the monitored object included in the image data a. When substantially matching the target assumed image, an alarm signal x1 is transmitted to the alarm lamp 33 on the intruder monitoring device 23 side. Whether or not the image data of the image data a matches the object assumed image data is determined as a result of the comparison and collation by the image data comparison / collation unit 28a provided in the image data generation means 28 of the video monitoring board 26. The target object assumed image data is data in which characteristics such as a moving pattern stay time of the monitoring target are stored in advance on the video monitoring device 22 side. Therefore, when the image data “a” substantially coincides with the above-mentioned target object assumed image, the alarm signal x1 is transmitted from the alarm signal transmitter 27 side to the intruder monitoring device 23 side.

  The image data generation means 28 includes an image data comparison / matching unit 28a, an object video image data creation unit (hereinafter referred to as an image data creation unit) 28b, and an object video image data registration unit (hereinafter referred to as an image data registration unit). .) 28c and a database 28d for storing image data of the monitoring object.

  The image data comparison / collation unit 28a compares the human image b (see FIG. 2A) indicated in the image data a with a monitoring target assumed image (not shown) stored in advance on the image data generation unit 28 side. The alarm permission signal q is transmitted to the alarm signal transmitter 27 side in the case of matching.

  The image data creation unit 28b is configured to generate an image data signal x2 and transmit it to the intruder monitoring device 23 side at the same time that the alarm signal x1 is issued from the video monitoring board 26 side. The image data signal x2 is data obtained by programming the data format shown in the image data table 30 shown in FIG.

  In addition, when there is a data request from the monitor screen 32 side that displays the image data table 30 (operation of the request operation unit 37), the image data creation unit 28b, based on the data of the image data table 30, FIG. The parameter graph 31 shown is transmitted to the intruder monitoring device 23 side by the parameter data signal x3.

  The image data creation unit 28b always automatically transmits a monitor image from the video monitoring device 22 side to the intruder monitoring device 23 side. Therefore, a monitor image of the image data a acquired by the video camera 21 is always displayed on the monitor screen 32 on the intruder monitoring device 23 side.

  The image data registration unit 28c stores the parameter graph 31 created by the image data creation unit 28b so that it can be reused (called) by a registration instruction from the intruder monitoring device 23 side. That is, by operating the registration operation unit 38 displayed on the monitor screen 32 on the screen, the image data registration unit 28c is registered so as to be reusable.

  The object data image data No (1 to n) attached to each object image image data is attached to the image data table 30, and the detected image column 33a, the detected size column 33b, and the stay time column are shown on the horizontal axis. 33c is a table with a correct / wrong input operation column 33d. When an alarm is issued from the alarm signal transmitter 27 in response to the acquired image data a by the video camera 21, it is newly created on the image data creation unit 28b side. As shown in FIG. 3, the image data table 30 is updated and displayed, for example, in addition to the Nth term next to the object video image data No (N-1).

  The parameter graph 31 is created based on the image data table 30, and is created on the image data creation unit 28b side by operating the request operation unit 37 provided on the screen of the image data table 30. . As shown in FIG. 4, the parameter graph 31 is a graph showing the relationship between the correct detection rate (referred to as the positive detection rate) (%) and the detection size, and the relationship between the positive detection rate and the staying time (s). It is a thing. Further, when it is determined on the monitor side that the parameter graph 31 needs to be registered, that is, when an improvement in the detection rate of the monitoring object can be expected, a registration procedure can be taken.

  The video monitoring board 26 on the video monitoring device 22 side receives the parameter information registration signal y2 designating registration from the intruder monitoring device 23 side, thereby creating parameter data based on the updated image data table 30, and video It is registered (saved) in the image data registration unit 28c of the image data generation means 28 on the monitoring device 22 side.

  When the intruder monitoring device 23 receives the alarm signal x1 from the video monitoring device 22 side, the intruder monitoring device 23 displays on the screen an alarm lamp 33 provided to issue an alarm to the supervisor side, the image data table 30 and the parameter graph 31. And a monitor screen 32.

  When the intruder monitoring device 23 side receives the alarm signal x1 from the video monitoring device 22 side, the alarm lamp 33 is turned on and an alarm is given that an intruder with high possibility of human intrusion has entered.

  As shown in FIG. 3, the monitor screen 32 displays an image data table 30 in which acquired data is displayed in a matrix and data processed into a parameter graph 31 as shown in FIG. As shown in FIG. 2A, the image data table 30 and the parameter graph 31 show image data acquired by the video camera 21 of the video monitoring device 22 when the human image b enters the intruder monitoring area z. It is created from data indicating characteristics of an object such as a detected image included in a.

  When the image data a substantially coincides with the assumed object image stored in advance on the video monitoring device 22 side, an image data signal x2 is generated on the video monitoring device 22 side. Further, the monitor screen 32 is connected to a computer (not shown), and data processing of various signals transmitted / received to / from the video monitoring device 22 side is performed.

  Here, as shown in FIG. 2B, when an animal (except a person) image h is captured, it is detected on the video monitoring device 22 side that it is not substantially the same as the assumed object image. The image data signal x2 is not generated. Accordingly, the image data table 30 is not displayed on the monitor screen 32 on the intruder monitoring device 23 side.

  However, if it is an animal image h but is erroneously detected, an image data signal x2 is generated and the image data table 30 is displayed on the monitor screen 32. In the case of erroneous detection, for example, animal image data a is displayed in the object video image data No. 32n of the image data table 30 shown in FIG.

  Next, the image data table 30 and the parameter graph 31 displayed on the monitor screen 32 will be described.

  As shown in FIG. 3, the image data table 30 displays a detection image column 33a, a detection size column 33b, a stay time column 33c, and a correct / incorrect input operation column 33d.

  In the detection image column 33a, an appearance image of the monitoring object acquired from the image data a is displayed. In the detection size column 33b, the long side dimension (cm) of the monitoring object is displayed. The staying time column 33c displays the staying time (seconds) of the monitored object in the screen. Furthermore, the correct / incorrect input operation field 33d is provided with correct and incorrect operation units.

  In this correct / incorrect input operation field 33d, for example, when the object video image data of the image data a written in the object video image data No32n is different from the object assumed image data stored in advance on the video monitoring device 22 side. In other words, the “wrong” operation unit 36n is operated in the case of the object video image data No 32n in the correct / wrong input operation column 33d shown in the image data table 30 of FIG. By this operation, the data on the database 28d side of the video monitoring device 22 is updated.

  On the other hand, as shown in FIG. 4, the parameter graph 31 is displayed in a graph for each stay time characteristic c and detected size characteristic d. The stay time characteristic c and the detection size characteristic d are obtained by tabulating and displaying the data of the image data table 30. The vertical axis indicates the positive detection rate (%), and the horizontal axis indicates the detection size (cm (vertical pix × horizontal pix). )) And dwell time (seconds) are displayed.

  The stay time characteristic c displays a stay time designation area s1, and the detection size characteristic d displays a detection size designation area s2. The stay time designating region s1 is set with a portion having a high positive detection rate (%) in the stay time characteristic c, for example, a range of 65% or more. In the detection size designation region s2, a portion having a high positive detection rate (%) in the detection size characteristic d, for example, a range of 70% or more is set. These setting ranges are updated and set by computer processing on the monitor screen 32 by appropriately varying them.

  Next, the operation of the intruder image monitoring system 20 will be described with reference to FIGS.

  As shown in FIG. 2A, when the video camera 21 on the video monitoring device 22 side captures a human image b that has entered the intruder monitoring area z, the captured image data a is converted into the video monitoring device 22. Sent to the side. The video monitoring device 22 that has received the image data a enters the video monitoring device 22 when it is determined that the image monitoring device 22 is substantially matched by comparing with the assumed object image stored in advance on the video monitoring device 22 side. An alarm signal x1 and an image data signal x2 are transmitted to the object monitoring device 23 side. At the same time, the image data a is transmitted from the video monitoring device 22 side to the intruder monitoring device 23 side and displayed on the monitor screen 32 <Step 1>.

  When the intruder monitoring device 23 side receives the alarm signal x1, the alarm lamp 33, which is an alarm device, is turned on. As the warning lamp 33 is turned on, the image data table 30 is displayed on the monitor screen 32 shown in FIG. At this time, the supervisor on the intruder monitoring apparatus 23 side checks whether the image data a of the video camera 21 is a person on the monitor screen 32. At that time, the monitor screen 32 can be visually confirmed from both the moving image and the still image.

  Next, the image data table 30 is displayed on the monitor side instead of the image, and the display of the human image is confirmed in the detected image column 33a. As a result of this confirmation, if correct detection (that is, detection of a person) is detected, the “correct” operation unit 35n of the correct / incorrect input operation field 33d is operated, and if an error is detected, the “error” operation unit 36n is operated. . When the parameter graph 31 is displayed, the request operation unit 37 displayed on the monitor screen 32 is operated (for example, a pen touch operation). By this operation, the data request signal y1 is transmitted from the intruder monitoring device 23 side to the video monitoring device 22 side <step 2>.

  Next, when the video monitoring device 22 side receives the data request signal y1, it is stored in the database 28d of the image data generation means 28, and is read out to the image data creation unit 28b side including the existing data, and the parameter data is read out. The included parameter signal x3 is generated and transmitted to the intruder monitoring device 23 side <Step 3>.

  Next, when the image data signal x2 is received on the intruder monitoring device 23 side, the parameter graph 31 created based on the update data is displayed on the monitor screen 32. Subsequently, on the monitor side of the intruder monitoring apparatus 23, the stay time designation area s1 and the detection size designation area s2 are reviewed on the screen of the parameter graph 31 shown in FIG. When it is determined that updating is necessary for the purpose of increasing the number or further improving the positive detection rate, arrows indicating the stay time designation area s1 and the detection size designation area s2 are displayed on the screen. Move or expand and contract to make fine adjustments. When this fine adjustment is completed, the parameter graph 31 is registered in the image data registration unit 28c on the video monitoring device 22 side by operating the registration operation unit 37 displayed on the parameter graph 31 (step 4).

  According to the intruder image monitoring system 20, an intruder that enters the intruder monitoring area through the above <Step 1> to <Step 4> is detected as an object to be monitored using the image data a of the monitoring camera. Whether or not there is can be determined with higher accuracy. Moreover, since the data by misdetection employ | adopted the method of deleting arbitrarily from the database on the supervisor side, the detection precision of the monitoring target object can be improved more.

  In addition, according to the intruder image monitoring system 20, the stay time is exemplified as the target object assumed image data. However, it is also possible to detect the detected size and the shape image of the monitored object and use this shape image. Is possible. Of course, these detected data can be used in appropriate combination.

  Furthermore, according to the intruder image monitoring system 20, a person has been described as an object to be monitored, but animals such as dogs, cats, frogs, and birds such as crows and birds such as crows are used as objects to be monitored, and the eating of a fruit is devastated. It can also be used as a preventive measure.

  Furthermore, according to the intruder image monitoring system 20, when the system 20 is used for another similar purpose, the image data table 30 and the parameter graph 31 stored in the image monitoring device 22 of the intruder image monitoring system 20 are used. Can be applied or can be used as they are, so that the initial adjustment is not necessary at the time of initial setting when installing another system, which is extremely useful.
