Description

  The present invention relates to a sensor / camera-linked intrusion detection apparatus that detects an object that has illegally entered using a sensor and a camera.

  Conventionally, this type of sensor / camera-linked intrusion detection device includes a surveillance camera and an intrusion detection sensor, and when the detection sensor detects an intruding object, the camera is pointed in the detection direction and the intruding object is photographed. (Japanese Patent Laid-Open No. 2003-44965).

  However, in the above-described sensor / camera-linked intrusion detection apparatus, an object that has entered a predetermined detection area may not be reliably detected. In other words, the detection sensor detects a wide area and reacts even with, for example, a car light outside the detection area, so that malfunctions such as photographing an image outside the detection area increase. If the detection area by the detection sensor is set to a predetermined area, malfunctions are reduced, but the detection line of the detection sensor cannot be visually confirmed, and it takes a long time to accurately set the detection area.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a sensor / camera interlocking intrusion detection device that can reliably detect an object that has illegally entered a predetermined setting area.

  In order to achieve the above object, a sensor / camera-linked intrusion detection apparatus according to the present invention includes a sensor unit that detects an object based on a change in a received amount of a detection line from a detection area, and the detection among the areas photographed by the camera. An image processing unit that detects an object by a change in a video signal from a specific area having a portion overlapping with the area, an area setting unit that sets the specific area on a monitor screen connected to the camera, and a sensor unit A detection signal generating unit that generates an object detection signal based on the detection signal and the detection signal from the image processing unit;

  In this configuration, when an object enters the area set by the area setting unit, the video signal of a specific area that is captured by the camera and sent to the image processing unit changes, and the detection line is received by the sensor unit. The amount also changes, and detection signals are output from both the sensor unit and the image processing unit. Based on both detection signals, an object detection signal is output from the detection signal generator to detect an intruding object. Here, since the first specific area serving as the detection area is set on the monitor screen, the area to be detected can be accurately set while looking at the screen, so that the detection of the intruding object is reliably performed with few malfunctions.

  In a preferred embodiment of the present invention, the specific area includes first and second specific areas, and the detection signal generation unit detects the detection signal from the sensor unit and the detection in the first specific area from the image processing unit. An object detection signal is generated in response to both of the signals or the detection signal in the second specific area from the image processing unit.

  In this configuration, two first and second specific areas are set by the area setting unit, (1) an object is detected by a video change in the first specific area, and a detection line from the sensor unit is detected. When an object is detected due to a change in received amount, an object detection signal is output from the detection signal generation unit based on both the detection signal from the sensor unit and the detection signal in the first specific area from the image processing unit. Or (2) an object detection signal is output from the detection signal generation unit in response to a detection signal in the second specific area from the image processing unit. For this reason, it is possible to reliably detect an intruding object in the first and second specific areas over a wide area. If the first specific area is an area that requires particularly accurate detection, an object detection signal is output only after receiving both the first and second detection signals in this area. Is made. In addition, since the first and second specific areas serving as detection areas are set on the monitor screen, the area to be detected can be accurately set while looking at the screen, so that the detection of the intruding object is reliably performed with few malfunctions. The

  In another preferred embodiment of the present invention, the detection signal generation unit receives both the detection signal from the sensor unit and the detection signal in the first specific area from the image processing unit, and outputs the first object detection signal. And a second object detection signal is generated in response to the detection signal in the second specific area from the image processing unit.

  In this configuration, two first and second specific areas are set by the area setting unit, an object is detected by a video change in the first specific area, and the amount of detection lines received from the sensor unit When an object is detected by a change, the first object detection signal is output from the detection signal generation unit based on both the detection signal from the sensor unit and the detection signal in the first specific area from the image processing unit. The Further, when an object is detected by a video change in the second specific area, a second object detection signal is output from the detection signal generation unit. For this reason, the detection of the intruding object in the first and second specific areas can be performed separately over a wide area, and phase security can be achieved by the detection in each specific area. In addition, since the first and specific areas that are detection areas are set on the monitor screen, the area to be detected can be accurately set while looking at the screen, so that the detection of the intruding object can be reliably performed with few malfunctions.

  In the embodiment of the present invention, further, when the luminance of the photographing area of the camera is equal to or lower than a predetermined luminance, the image processing unit is deactivated and only the detection signal from the sensor unit is used to detect the first from the detection signal generation unit. Night adjustment unit for generating the object detection signal. According to this configuration, the first object that is output from the detection signal generation unit based only on the detection signal of the sensor unit when the surroundings become dark and the luminance of the shooting area of the camera becomes equal to or lower than the predetermined luminance. The detection signal can reliably detect the intruding object.

  In an embodiment of the present invention, when the detection line is an infrared ray and the temperature of the detection area becomes equal to or higher than a predetermined temperature, the sensor unit is deactivated and detected only by a detection signal from the image processing unit. A temperature adjustment unit is provided that generates a first object detection signal from the signal generation unit. According to this configuration, even when the ambient temperature becomes high in summer and the like, and the intruding object cannot be accurately detected by infrared rays, it is output from the detection signal generation unit based only on the detection signal of the image processing unit. An intruding object can be reliably detected by the first object detection signal.

  In another embodiment of the present invention, the specific area includes first and second specific areas, and the detection signal generation unit is configured to detect the detection signal from the sensor unit and the first specific area from the image processing unit. When both of the detection signals are received and when the detection signal from the sensor unit is received and the detection signal in the second specific area from the image processing unit is not received, the object detection signal is generated. According to this configuration, for example, when the site to be monitored faces a road, by setting the second specific area as an outer road, only an entering object in the first specific area is detected. A stable sensor / camera-linked intrusion detection device that does not detect the traffic of cars or people in the second specific area can be obtained.

  In an embodiment of the present invention, the sensor unit has a passive infrared detector that detects far infrared rays from the detection area. According to this configuration, the object can be reliably detected by the sensor unit with a simple configuration.

  Embodiments of a sensor / camera-linked intrusion detection device according to the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view schematically showing an optical configuration of an installed state of the sensor / camera interlocking intrusion detection apparatus according to the first embodiment of the present invention. This apparatus is attached to, for example, a wall or a pillar P of a building such as a general house or factory, and detects an object Q such as a human body or an animal that illegally enters a predetermined detection area set outside the building. The object Q is detected by setting a plurality of detection areas A0 to An outside the building and changing the amount of detection lines received from the intruding object Q when the detection areas A0 to An are moved. And a CCD camera 2 for photographing the object Q.

  As the sensor unit 1, for example, a passive infrared (PIR) method is adopted, and a pyroelectric element that detects far infrared rays, which are detection lines emitted from the intruding object Q in the detection areas A <b> 0 to An, in the case 10. And a Fresnel lens 12 disposed in front of the infrared detector 11 to set the detection areas A0 to An, a signal generation circuit 13, and the like. The sensor unit 1 collects far-infrared rays emitted from the object Q that has entered the detection areas A0 to An by the Fresnel lens 12 and enters the passive infrared detector 11. When it changes more than a certain level, the signal generation circuit 13 outputs a detection signal of the intruding object Q. As described above, by using the passive infrared detector 11, the intruding object Q can be reliably detected with a simple configuration.

  FIG. 2 is a block diagram showing a circuit of the sensor / camera interlocking intrusion detection apparatus. In addition to the sensor unit 1 and the CCD camera 2, this apparatus includes a monitor screen 6 connected to the camera 2 and an area setting unit 3 for setting a first specific area AC1 on the monitor screen 6, as will be described later. An operation unit 30 such as a key or a mouse for manually operating the area setting unit 3, and an image processing unit 4 for detecting the object Q by a change in the video signal MS in the first specific area AC1. A detection signal generator 5 that receives both the detection signal PD from the sensor unit 1 and the detection signal MD1 from the image processing unit 4 and outputs a first object detection signal DE1. In this embodiment, the detection signal generation unit 5 includes a first connected to the image output unit 4 in order to reliably detect an illegally intruding object without unnecessarily outputting an object detection signal. A delay circuit 51, a second delay circuit 52 connected to the sensor unit 1, and an AND circuit that outputs the first object detection signal DE1 when output signals are output from both the circuits 51 and 52, respectively. 53. While the sensor unit 1 and the camera 2 are installed at a security site, the area setting unit 3, the image processing unit 4, the detection signal generation unit 5, and the operation unit 30 are arranged, for example, in a security room away from the security site. The

  FIG. 3 shows the monitor screen 6 of the PC. On the monitor screen 6, by specifying the coordinate axes of the video by the camera 2 by operating the operation unit 30, that is, by specifying the four points 61 to 64 on the monitor screen 6, A setting signal AS1 for setting the contour line is output to the image processing unit 4, the first specific area AC1 is set in the image processing unit 4, and the area AC1 is displayed on the monitor screen 6. The image processing unit 4 detects a change in the video signal in the first specific area AC1.

  Here, as shown in FIG. 1, the detection areas A <b> 0 to An by the sensor unit 1, that is, the visual field V <b> 1 of the sensor unit 1 is roughly set because accurate setting is troublesome. V2 is set to be narrower and deeper than this. The first specific area AC1 is a part of the field of view V2 of the camera 2, and areas A1 to A4 that are a part of all the detection areas A0 to An of the sensor unit 1 are included in the first specific area AC1. included. That is, the specific area AC1 and all the detection areas A0 to An have overlapping portions. When the object Q enters the detection area A1 to A4 included in the first specific area AC1, the first object detection signal DE1 is output (reported) from the detection signal generator 5 in FIG. .

  According to the first embodiment described above, among all the detection areas A0 to An by the sensor unit 1 in FIG. 1, the first specific area AC1 set in the area setting unit 3 in the video area of the camera 2 is included. When the object Q enters the predetermined detection areas A1 to A4, the detection signal generator 5 outputs a first object detection signal DE1 indicating the detection of the intruding object Q. That is, as shown in FIG. 2, the detection signal PD including a rectangular wave signal is output from the sensor unit 1 by the intruding object Q, and image processing is performed due to a change in the video signal MS in the first specific area AC1. The detection signal MD1 is output from the unit 4. The image processing unit 4 uses, for example, a general image processing technique that outputs the detection signal MD1 when the luminance signal included in the video signal MS changes by a certain width within a certain time. The detection signals PD and MD1 from the sensor unit 1 and the image processing unit 4 are respectively delayed by the first and second delay circuits 51 and 52 of the detection signal generation unit 5 to suppress malfunction due to an error signal. After that, the signal is sent to the AND circuit 53. When the AND circuit 53 is turned on, the first object detection signal DE1 is output to detect the intruding object Q. Based on the signal DE1, operations such as alerting in the security room and generation of sound and / or light at the security site are performed.

  As described above, the image area by the camera 2 is set to the first specific area AC1 by the area setting unit 3, and the object Q is detected by detecting both the sensor unit 1 and the camera 2 in the specific area AC1. Since the detection signal is output, malfunctions are reduced and the intruding object Q can be accurately detected. Here, since the first specific area AC1 serving as the detection area is set on the monitor screen 6, if the sensor unit 1 and the camera 2 are installed at the security site, there is no need to go to the security site after that. The area to be detected can be accurately set while looking at the Morita screen 6 in the police room. Therefore, the detection of the intruding object is surely performed with few malfunctions, and the operation for setting the warning area becomes easy.

  FIG. 4 is a block diagram showing a circuit of a sensor / camera interlocking intrusion detection apparatus according to a second embodiment of the present invention, and FIG. 5 shows a monitor screen 6 used for this. In contrast to the first embodiment, this apparatus uses the first and second setting signals AS1 and AS2 from the area setting unit 3 as shown in FIG. And a second specific area AC2 that falls outside this area, and in these specific areas AC1 and AC2, when the video signal MS from the camera 2 shown in FIG. The difference is that the two detection signals MD1 and MD2 are output to the detection signal generator 5. For example, the first specific area AC1 is an area near the outside of the entrance / exit of a building that requires accurate detection of an intruder, and the second specific area AC2 is an area that includes an area slightly away from the entrance / exit. As the detection signal generator 5, a third delay circuit 54 to which the second detection signal MD2 is input is added, and an output signal of the third delay circuit 54 and an output signal of the AND circuit 53 are input. OR circuit 55 is additionally provided.

  According to the second embodiment, the first and second specific areas AC1 and AC2 are set in the image processing unit 4 by the setting signals AS1 and AS2 from the area setting unit 3. When the image processing unit 4 detects a change in the video signal MS in the specific areas AC1 and AC2, the image processing unit 4 outputs first and second detection signals MD1 and MD2, respectively. The first detection signal MD1 is input to the delay circuit 51, and the second detection signal MD2 is input to the delay circuit 54. In addition, the first detection signal MD1 from the first delay circuit 51 and the detection signal PD from the sensor unit 1 are input to the AND circuit 53 of the detection signal generation unit 5 as in the first embodiment. Is done. Further, the output signal from the AND circuit 53 and the output signal from the third delay circuit 54 are input to the OR circuit 55, and the first object detection signal DE1 is output from the OR circuit 55, and the intruding object Q Is detected.

  Therefore, in the first specific area AC1, the object detection signal DE1 is output only when detection is performed by both the sensor unit 1 and the camera 2, so that malfunctions are reduced and the intruding object Q can be detected accurately. It becomes. On the other hand, in the second specific area AC2, since the object detection signal DE1 is output only by detection by the camera 2, the second specific area AC2 is, for example, a wide area having a deeper depth than the detectable area by the sensor unit 1. Therefore, the alert area can be easily expanded. Also, since the first and second specific areas AC1 and AC2 which are detection areas are set on the monitor screen 6, the area to be detected can be set accurately while looking at the monitor screen 6, and the warning area is set. The operation becomes easier.

  FIG. 6 shows a circuit of a sensor / camera interlocking intrusion detection apparatus according to a third embodiment of the present invention. In contrast to the second embodiment, this apparatus receives the second object detection signal DE2 from the third delay circuit 54 together with the first object detection signal DE1 output from the AND circuit 53 of the detection signal generator 5. The difference is that each is output individually.

  According to the third embodiment, the first detection signal MD1 from the image processing unit 4 and the detection signal PD from the sensor unit 1 pass through the first and second delay circuits 51 of the detection signal generation unit 5. The signal is input to the AND circuit 53, from which the first object detection signal DE1 is output. A second object detection signal DE2 is output from the third delay circuit 54 based on the second detection signal MD2 from the image processing unit 4. In this way, since the detection of the intruding object Q in the first and second specific areas AC1 and AC2 can be distinguished, for example, a speaker and a light emitter are installed at the security site, and the second specific area Upon receipt of the second object detection signal DE2 by the detection at AC2, a sound is generated to alert the intruder Q from the speaker, and the first object detection signal DE1 is received from the threatening sound from the speaker and the light emitter. A step-by-step guard that regenerates the intruder Q by generating both of these lights is possible.

  FIG. 7 shows a circuit of a sensor / camera interlocking intrusion detection apparatus according to a fourth embodiment of the present invention. This device compensates for a decrease in the capability of the camera 2 when the surroundings become dark. In the first embodiment shown in FIG. 2, on the output side of the first delay circuit 51 of the detection signal generator 5, A night adjustment unit 7 including a luminance setting unit 70 and a luminance comparison unit 71 is additionally provided. In the luminance comparison unit 71, the luminance of the image of the image processing unit 4 sent from the first delay circuit 51, and the luminance setting are provided. The predetermined set luminance set by the unit 70 is compared. An OR circuit 54 to which signals from the luminance comparison unit 71 and the first delay circuit 51 are input, an output signal from the OR circuit 54 and an output signal from the second delay circuit 52 connected to the sensor unit 1 are input. An AND circuit 53 is provided.

  According to the fourth embodiment, the luminance in the first specific area AC1 photographed by the camera 2 and the luminance set by the luminance setting unit 70 are compared by the luminance comparison unit 71, and the night approaches. When the surroundings become dark due to the influence of the weather and the luminance in the first specific area AC1 is less than or equal to the set luminance, a high level signal is output from the luminance comparison unit 71 to the OR circuit 54. A high level signal is always output from the OR circuit 54 to the AND circuit 53. Therefore, even when the detection signal from the image processing unit 4 does not exist, the first object detection signal DE1 is output from the AND circuit 53 only by the detection signal PD from the sensor unit 1. In this way, when the surroundings become dark and the detection signal MD1 from the image processing unit 4 is not output, the intruding object Q can be reliably detected based only on the detection signal PD of the sensor unit 1. When the surroundings are bright, the object detection signal DE1 is output when both the detection signal PD from the sensor unit 1 and the detection signal MD1 based on the image signal from the camera 2 are input to the AND circuit 53.

  FIG. 8 shows a circuit of a sensor / camera interlocking intrusion detection apparatus according to a fifth embodiment of the present invention. This device compensates for a decrease in the detection capability of the sensor unit 1 due to an increase in ambient temperature. In the first embodiment shown in FIG. 2, the detection signal generator 5 includes the detection areas A0 to An in the sensor unit 1. The temperature adjustment includes a temperature sensor 81 that detects the temperature of the sensor, a temperature setting unit 82 that sets a predetermined temperature, and a temperature comparison unit 83 that compares the temperature detected by the temperature sensor 81 and the temperature set by the temperature setting unit 82. A part 8 is additionally provided. Further, an OR circuit 56 to which an output signal of the temperature comparison unit 82 and a signal from the second delay circuit 52 connected to the sensor unit 1 are respectively input, an output signal of the OR circuit 56 and the first delay circuit 51 An AND circuit 53 to which an output signal is input is provided.

  According to the fifth embodiment, the temperature of the detection areas A0 to An by the sensor unit 1 is detected by the temperature sensor 81, and the detected temperature and the set temperature by the temperature setting unit 82 are compared by the temperature comparison unit 83. When the temperature of the detection areas A0 to An is equal to or higher than a set temperature, the temperature comparison unit 83 outputs a high level signal to the OR circuit 56, and accordingly, the OR circuit 56 constantly outputs a high level signal to the AND circuit 53. Output to. Therefore, even when the detection signal PD from the sensor unit 1 does not exist, the first object detection signal DE1 is output from the AND circuit 53 only by the detection signal MD1 from the image output unit 4. In this way, when the infrared detector 11 is used as the sensor unit 1, when the temperature of the detection area of the sensor unit 1 becomes high in summer or the like, the detection of the intruding object Q by infrared rays tends to be inaccurate. On the other hand, when the temperature detected by the temperature sensor 81 is equal to or higher than a predetermined temperature, the intruding object Q can be reliably detected based only on the detection signal MD1 from the image processing unit 4. When the temperature is equal to or lower than the set temperature, the object detection signal DE1 is output when both the detection signal PD from the sensor unit 1 and the detection signal MD1 based on the image signal from the camera 2 are input to the AND circuit 53.

  Next, a sixth embodiment will be described with reference to FIGS. In this embodiment, as shown in FIG. 9, the visual field V2 of the camera 2 is set wider than the visual field V1 of the sensor unit 1. In the field of view V2 of the camera 2, a fence 37 that partitions the site 35 and the site 36 is installed, and the site 36 is, for example, a road. In this case, the field of view V1 of the sensor unit 1 has also reached the off-site 36, but since the vehicle or people who are not intended to enter the off-site 36 come and go, the sensor unit 1 detects a moving object outside the on-site 36. However, the object detection signal should not be output (reported). On the other hand, since the site 35 is a short distance, the reliability of the detection of the approaching object Q by the sensor unit 1 is high, so there are few false alarms even if the object detection signal is output by the detection of only the sensor unit 1. Accordingly, the area setting unit 3 shown in FIG. 10 causes the inside 35 of the site to be the first specific area AC1 and the outside 36 of the site to be the second on the monitor screen 6 with the fence 37 as a boundary, as shown in FIG. Is set in each of the specific areas AC2.

  As shown in FIG. 10, the sensor / camera interlocking intrusion detection apparatus according to the sixth embodiment performs image processing when the video signal MS from the camera 2 changes in the first and second specific areas AC1 and AC2. First and second detection signals MD1 and MD2 are output from the unit 4 to the detection signal generation unit 5, respectively. The detection signal generator 5 is a knot circuit 57 that takes the logical negation of the second detection signal MD2, a first delay circuit 51 that delays the first detection signal MD1, and a first delay circuit that delays the detection signal PD from the sensor unit 1. 2 delay circuits 52, a third delay circuit 54A for delaying a signal from the knot circuit 57, an OR circuit 58 to which output signals from the first and third delay circuits 51 and 54A are input, and the OR circuit An AND circuit 59 to which the output signal of the circuit 58 and the output signal of the second delay circuit 52 are input is provided. Thereby, the detection signal generation unit 5 receives both the detection signal PD from the sensor unit 1 and the detection signal MD1 in the first specific area AC1 from the image processing unit 4, and the detection signal from the sensor unit 1. When the PD is received and the detection signal MD2 in the second specific area AC2 from the image processing unit 4 is not received, the object detection signal DE1 is generated.

  According to the sixth embodiment, when the detection signal PD is output from the sensor unit 1 and the detection signal MD2 in the outer second specific area AC2 is not output from the image processing unit 4, that is, When the camera 2 does not detect the traffic of a car or a person outside the premises 36, the output signal of the knot circuit 57 becomes high level, the output signal of the OR circuit 58 also becomes high level, and the object detection signal DE1 is output from the AND circuit 59. Is output (reported). In this state, it is determined that the sensor unit 1 has detected the approaching object Q in the first specific area AC1 inside. In other words, even when the detection signal PD is output from the sensor unit 1, when the detection signal MD2 is output, the output of the knot circuit 57 is at a low level, so the object detection signal DE1 is Not output. Therefore, when there is a traffic of a car or a person who is not intended to enter outside the site 36 and the camera 2 detects this, even if the detection signal PD of the car or person is output from the sensor unit 1, Not reported.

  On the other hand, when the detection signal PD is output from the sensor unit 1 and the camera 2 detects the entering object Q in the first specific area AC1 on the inner side, and the detection signal MD1 is output from the image processing unit 4, Since the output signal of the OR circuit 58 becomes high level, the object detection signal DE1 is output (reported) from the AND circuit 59. Therefore, even if a car or a person is detected by the camera 2 in the outer second specific area AC2 and the output signal of the knot circuit 57 is at a low level, the intruding object Q exists in the inner first specific area AC1. For example, when both the sensor unit 1 and the camera 2 detect this, the object detection signal DE1 is output. Therefore, it becomes a stable sensor / camera interlocking type intrusion detection device that can reliably detect the intruding object Q in the first specific area AC1.

  In the above embodiment, the PIR passive infrared detector 11 is used as the sensor unit 1. However, an AIR method is adopted in which near infrared light is projected as a detection line and near infrared light reflected from an object is detected. May be. In addition, an ultrasonic or radio wave type active sensor including a transmission element and a reception element that transmit and receive ultrasonic waves or radio waves as detection lines can be used.
