In the present embodiment, the image sensor 1 is used as an imaging device. However, the image sensor 1 may not be an image sensor that detects an intruder by image processing. For example, a combination of a surveillance camera and an infrared sensor may be used.

  The image sensor 1 includes a control unit 100 that controls the entire image sensor, an imaging control unit 101, an imaging unit 103 that includes a CCD, a CMOS (CIS), and the like that images a monitoring target, an illumination unit 102 that illuminates an imaging range, and a captured image. Image analysis unit 104 that extracts basic data for detecting an intruder from the image, intrusion determination means 109 that determines the accuracy of the presence of the intruder in multiple stages from the extracted basic data, and image data that temporarily stores the captured image The storage unit 110 includes an image data output unit 111 that outputs an image, and a connection I / F (interface) 112 that performs data communication with the monitoring device 2.

  The control unit 100 controls each part and the whole of the image sensor 1. The imaging control unit 101 controls the illumination unit 102 and the imaging unit 103 under the control of the control unit 100. The imaging unit 103 periodically images the monitoring area under the control of the imaging control unit 101, and temporarily accumulates the captured images in the image data storage unit 110. The image data storage unit 110 includes a ring-structured buffer, stores a predetermined number of images (for example, about 10 images), and can circularly store old images by sequentially replacing them with new images. When the monitoring device 2 is set to the release mode, or when the monitoring device 2 is set to the monitoring mode and the intrusion is not detected normally, the predetermined number of images is stored while being updated to the latest image by cyclically storing in this way. ing. Further, the image captured by the image capturing unit 103 may be output in parallel to the image data output unit 111 if there is a request for the latest image.

  Further, the image captured by the imaging unit 103 is also input to the image analysis unit 104. The image analysis unit 104 includes a background image storage unit 105, a difference extraction unit 106, a tracking unit 107, and an image attribute calculation unit 108, and the presence of a moving object is detected by comparing the latest captured image with the background image. Detection is performed, and attributes such as a human attribute, a small animal attribute, a light attribute, and a shadow attribute of the image in the detection area of the moving object are calculated.

  The background image storage unit 105 of the image analysis unit 104 stores in advance a background image of the imaging region (an image when there is no moving object such as an intruder). The difference extraction unit 106 performs a difference process between the input image obtained by the imaging unit 103 and the background image stored in the background image storage unit 105, and extracts a difference area having a change. If the tracking means 107 determines that the difference area obtained by the difference extraction means 106 is due to the same object as the difference area in the previous frame, the tracking means 107 gives the previous tracking information to the current difference area. The determination that they are the same object is performed, for example, by using a condition that the amount of movement of the center of gravity and the change in the size of the difference area are within a certain range.

  The image attribute calculation unit 108 includes, for example, a human attribute calculation unit 113, a small animal attribute calculation unit 114, a light attribute calculation unit 115, a shadow attribute calculation unit 116, and the like, and calculates each attribute. In addition to this, it is also possible to use other types of attribute calculation means that can improve the accuracy of determining whether or not a person has entered. The human attribute calculation unit 113 calculates a “human attribute value” that is a high value when the difference area obtained by the difference extraction unit 106 is a person. The human attribute value is a feature amount representing humanity, for example, the size of the difference area, a normalization function with the background image (the degree of coincidence between the background image and the input image), and the edge change rate when compared with the background image Etc.

  The small animal attribute calculation means 114 calculates a “small animal attribute value” that is high when the difference area is a small animal. The small animal attribute value is calculated from a feature amount representing the small animal character, for example, the size of the difference area, the degree of coincidence between the moving direction and the long axis, and the edge change rate when compared with the background image.

  The light attribute calculation unit 115 calculates a “light attribute value” that is a high value when the difference region is light. The light attribute value is calculated from a feature amount representing the lightness, for example, an average luminance value of the difference area in the non-illuminated image, a normalized correlation with the background image, and a rate of change of the edge when compared with the background image. .

  The shadow attribute calculation unit 116 calculates a “shadow attribute value” that is high when the difference area is a shadow. The shadow attribute value is calculated from a feature amount representing the likelihood of shadow, for example, the average luminance value of the difference area in the non-illuminated image, the normalized correlation with the background image, and the edge change rate when compared with the background image.

  The intrusion determination unit 109 determines whether the difference area obtained in the difference area is a person using the human attribute value, the light attribute value, the shadow attribute value, and the small animal attribute value. When the human attribute value is high and the light, shadow, and small animal attribute values are low, it is determined as “person”. The threshold value is set in three stages, and the accuracy of whether or not the difference area is caused by an intruder is determined at three levels. For example, the lowest level first person intrusion detection signal is output when it is determined by the analysis of the image that the difference area is sufficiently likely to be caused by an intruder but the accuracy is low. When the intruder detection level is determined to be higher than the “intruder detection” level, the second level intrusion detection signal of the higher level is output, and the intruder has higher accuracy than the “intruder detection” level. Is determined to be the “intruder confirmation” level, which is almost certain, the third level intrusion detection signal of the higher level is output. These intrusion detection signals are transmitted as flag information or coded digital information to the monitoring device 2 via the connection interface 112.

  The calculation method of each attribute value and the determination threshold value for performing such determination are freely set according to the monitoring target environment such as the topography of the monitoring area, the background, the relationship between natural light, artificial light, and shadows. However, it is desirable to determine an optimum value from experimental data according to the environment. For example, in various environments (indoor, outdoor, weather, daytime, night, etc.), experiments or simulations that move people or cause false alarms are repeated, and experimental data or simulation data is accumulated and analyzed. This makes it possible to obtain more accurate attribute value features and threshold information.

  The intrusion detection signal as the determination result is held in the intrusion determination unit 109 until an erasure request is received from the control unit 100. When a higher level determination is made based on the latest image, the old determination result is configured to be replaced with a determination result at a higher level. When the intruder is no longer detected in the captured image data, the control unit 100 erases the intrusion detection signal that is the determination result held in the intrusion determination unit 109.

  If it is determined by the intrusion determination means 109 that “human detection”, “intruder detection” or “intruder confirmation” is in the monitoring mode, the image data storage means 110 stores the image data under the control of the control means 100. The image stores and holds several consecutive images immediately before the determination and several images immediately after the determination. For example, assuming that the image data storage unit 110 can hold 10 images, the immediately preceding 3 images including the determination time and the immediately following 7 images are stored, and this image is received until a deletion request is received from the monitoring device 203. Hold.

  The image data output unit 111 adds image specifying information and an identification symbol to the accumulated image stored in the image data accumulation unit 110 or the latest image captured by the imaging unit 103 based on a request from the monitoring device 2. And transmitted via the connection interface 112. These images are transmitted to the monitoring center device 8 by the monitoring device 2 and used for confirming the intrusion status by the monitoring center monitor.

  Next, the determination processing procedure by the image sensor 1 will be described using the flowchart of FIG. The image sensor 1 calculates attribute values (light, shadow, small animal) other than a person in parallel with the person attribute value, and when the person attribute value is high and the attribute value other than the person is low, to decide. Then, the probability that the change area is a person is determined at three levels (intruder confirmation> intruder detection> person detection). If the accuracy is lower than “human detection”, the determination is “other than human”.

  First, the imaging control unit 101 controls the illumination unit 102 and the imaging unit 103 to acquire an illumination image when the illumination is turned on and an unilluminated image when the illumination is turned off (S201, S202).

  Difference processing between the acquired input image and the background image stored in the background image storage unit 105 is performed, and a difference region obtained by combining pixels whose luminance difference values are equal to or greater than a predetermined threshold is extracted (S203). If the tracking unit 107 determines that the extracted difference area is the same moving object as the difference area of the previous frame, the difference area information (tracking information) up to the previous time is added to the current difference area ( S204). Whether it is due to the same moving object is determined based on conditions such as whether the amount of movement of the center of gravity and the change in the size of the difference area are within a certain range.

  When these pre-processes are completed, a difference area attribute calculation process is performed (S205). In the attribute calculation process, various attributes are calculated. In this embodiment, an example of calculating a human attribute, a small animal attribute, a light attribute, and a shadow attribute is shown. When each attribute value is calculated, it is determined whether or not a person has entered based on those attribute values (S206). A specific example of a method for calculating each attribute value and a method for determining a human intrusion will be described below.

(Example of how to calculate each attribute value)
The human attribute of the difference area is calculated by weighting the feature amounts as in the following (1) to (3) and obtaining the sum.
(1) If the difference area size (T1) is within a certain range, the possibility of being a person is high. (2) If the similarity between the input image and the background image in the difference area is low, the possibility of a person is high. High (3) If the rate of change of the edge of the input image compared to the background image in the difference area is high, the possibility of a person is high.
These feature values are normalized so as to approach 1 when the possibility of being a person is high and to approach 0 as it is low. The normalized feature values are a1, a2, and a3, the weights for the feature amounts are b1, b2, and b3, and the human attribute value is obtained by the following equation.
Human attribute value = a1 × b1 + a2 × b2 + a3 × b3 where b1 + b2 + b3 = 1

The small animal attributes are calculated, for example, by weighting the following features (4) to (6) and calculating the sum.
(4) When the area of the difference area is small, the possibility of being a small animal is high (5) When the degree of coincidence between the inclination of the major axis of the difference area and the moving direction is high, the possibility of a small animal is high (6) In the difference area If the rate of change of the edge of the input image compared to the background image is high, the method of calculating the small animal attribute value from such a feature amount that is likely to be a small animal is the same method as the method of calculating the human attribute value. Use. However, weighting and other conditions for these feature quantities are determined through experiments or the like according to the environment.

The light attribute value is calculated, for example, by weighting the following feature amounts (7) to (9) and obtaining the sum.
(7) If the average brightness of the difference area in the unilluminated image is high, the possibility of light is high. (8) If the input image of the difference area and the background image are high, the possibility of light is high (9). When the rate of change of the edge of the input image compared with the background image of the difference area is low, the method of calculating the light attribute value from such a feature amount having a high possibility of light is the same as the method of calculating the human attribute value. Use the method. However, weighting and other conditions for these feature quantities are determined through experiments or the like according to the environment.

The shadow attribute value is calculated, for example, by weighting the feature quantities (10) to (12) and obtaining the sum.
(10) If the average luminance value of the difference area in the non-illuminated image is low, there is a high possibility of being a shadow. (11) If the similarity between the input image and the background image in the difference area is high, it may be a shadow. A method of calculating a shadow attribute value from such a feature amount having a high possibility of a shadow when the edge change rate of the input image compared with the background image of the high (12) difference area is low calculates a human attribute value. A method similar to the method is used. However, weighting and other conditions for these feature quantities are determined through experiments or the like according to the environment.

(Example of determination method for “intrusion of people”)
It is determined whether or not the difference area is “human intrusion” using the various attribute values calculated by the above-described method. This determination is made by dividing the case of “human intrusion” into three levels. Using the threshold values X1, X2, and X3 for determining human attribute values and the threshold values Y1, Y2, and Y3 for determining other attribute values (for example, light, shadow, and small animal attribute values), Determine. These threshold values are stored in the intrusion determination means 109 of the image sensor 1. The threshold values have a relationship of X1 <X2 <X3 and Y1 <Y2 <Y3.

  Note that the above threshold values (X1 to X3, Y1 to Y3) are based on a large number of image analysis data collected by moving a person in various environments assumed as monitoring targets, misinformation data obtained by detection experiments, and the like. Thus, the probability of human invader can be calculated statistically. Also, based on the past information of the difference area tracked by tracking, the past values of human attribute value, light attribute value, shadow attribute value, small animal attribute value are accumulated, and the possibility of human intrusion using the accumulated attribute value The determination may be made.

With reference to FIG. 13, a method for determining the accuracy of “person intrusion” in a plurality of stages will be described. FIG. 13 shows a determination result based on the relationship between the human attribute value and the non-human attribute value. The attribute values other than the person are determined using the maximum value among the calculated “small animal attribute value”, “light attribute value”, and “shadow attribute value”.
In the figure, “A” indicates a so-called “normal” case where it is determined that no person has entered. That is, when the human attribute value is smaller than X1 or other attribute values are larger than Y3, the intrusion determination unit 109 determines “normal”.
In the figure, “B” is a case where the possibility of factors other than humans still remains and cannot be determined without the intrusion of a person, so-called “human detection” (first level intrusion detection). Shows the case. That is, when the human attribute value is between X1 and X2 and the other attribute value is larger than Y3, or when the human attribute value is larger than X1 and the other attribute value is between Y2 and Y3, the intrusion determination The means 109 determines “person detection”.
In the figure, “C” is a case in which there is a slight possibility of a factor other than a person, and it cannot be determined that there is an intrusion of a person, and so-called “intruder detection” (second level intrusion detection). ). That is, intrusion determination means when the human attribute value is between X2 and X3 and the other attribute value is smaller than Y2, or when the human attribute value is larger than X3 and the other attribute value is between Y1 and Y2. 109 determines “intruder detection”.
In the figure, “D” indicates a case where it can be determined that the person is an intruder without fail, and so-called “intruder confirmation” (third level intrusion detection). That is, when the human attribute value is larger than X3 and the other attribute values are smaller than Y1, the intrusion determination unit 109 determines “intruder confirmation”.

  The operation procedure of each image sensor 1 in response to a request from the monitoring device 2 will be described with reference to FIG. The image sensor 1 transmits information corresponding to the request to the monitoring device 2 in response to a request signal from the monitoring device 2. When each image sensor 1 confirms whether the request signal of the monitoring device 2 is a request addressed to itself, and determines that the request signal is addressed to itself (S210; Yes), the received request signal is an accumulated image (data ) Is a request signal (S211). If it is a request signal for an accumulated image (S211; Yes), the image data output means 111 transmits the accumulated image accumulated in the image data accumulation means 110 to the monitoring device 2 (S218). Otherwise (S211; No), the process proceeds to step S212. In step S212, it is determined whether the received request signal is a request signal for the latest image (data). When the request signal is the latest image (data) (S212; Yes), the image data output unit 111 transmits the latest image captured by the imaging unit 103 to the monitoring device 2 via the connection interface 112 (S213).

If it is not the latest image transmission request (S212; No), it is confirmed whether it is a status report request signal (S214). If it is not the current report request (S214; No), the process proceeds to step S219. In step S219, processing according to the received request signal is performed. For example, in the case of a request for deleting the stored image, the holding of the image held in the image data storage unit 110 is released, and the normal operation is restored. Alternatively, when a monitor end signal or a transmission stop command is received, transmission of the latest image is stopped. If it is a status report request signal (S214; Yes), it is checked whether the intrusion determination means 109 holds an intrusion detection signal as a determination result (S215). The intrusion detection signal is transmitted to the monitoring device 2 (S216). When the intrusion detection signal is not held (S215; No), a normal signal is transmitted to the monitoring device 2 (S217).
Note that a request for a status report from the monitoring device 2 is made by periodically polling each image sensor 1.

(Monitoring device)
FIG. 8 is a functional block diagram of the monitoring device 2 that can be connected to the remote monitoring device (monitoring center device) of the present invention. Based on main control means 201 for controlling the entire monitoring device 2, image sensor interface 202 (hereinafter referred to as “image sensor I / F 202”) that is a connection interface with the image sensor 1, and an intrusion detection signal from the image sensor 1, Response processing selection means 203 for selecting response processing, equipment control means 204 for controlling the activation of the smoke generating device 3, sensor monitoring means 205 for monitoring the states of the various sensors 4 to 6, security mode set by the mode setting device 9, Storage means 206 for storing an intrusion detection signal and image information received from the image sensor 1, a flag indicating the transmission status of an image to the monitoring center device 8, various programs, and the like, and when the monitoring status is displayed on the screen and an abnormality is detected Data with the display means 207 for sounding the buzzer and displaying the location of the abnormality on the screen and the monitoring center device 8 And a communication control unit 208 for transmitting and receiving. Note that the intrusion detection signal stored in the storage unit 206 is stored for each image sensor 1.

  The monitoring device 2 stores a correspondence table of the smoke generation device 3 corresponding to the image sensor 1 in the storage unit 206. FIG. 10 illustrates a correspondence table between the image sensor 1 and the smoke generation device 3 stored in the storage unit 206. The equipment control means 204 uses such a table to activate the smoke generator 3 corresponding to the image sensor 1 that has detected intrusion. In addition, when the image sensor 1 and the smoke generating device 3 are installed in a relationship of plural: 1, one image sensor 1 corresponding to the smoke generating device 3 is specified in the table, and the specified image sensor 1 is specified. Even if the smoke generating device 3 is activated only when an intrusion is detected, by associating all of the plurality of image sensors 1 with the smoke generating device 3, any one of the associated image sensors 1 intrudes. Even when it is detected, the smoke generating device 3 may be activated. Further, when the image sensor 1 and the smoke device 3 are installed in a plurality of relationships 1: when the corresponding image sensor 1 is in the “intrusion detection” state, the plurality of smoke devices 3 are separated at a certain time interval. Even if it is made to start automatically one after another, only one of the plurality of smoke generating devices 3 is automatically started by the monitoring device 2, and the remaining smoke generating devices 3 are started by a control signal from the monitoring center device You may make it make it.

  When the mode setting unit 9 sets the monitoring mode, the main control unit 201 is based on signals from the image sensor 1 and the various sensors 4 to 6, and the sensor monitoring unit 205 and the corresponding processing selection unit 203 are the various sensors 4 to 6. In addition, the state of the image sensor 1 is monitored, and when an abnormality occurs, intrusion information is transmitted to the monitoring center device 8 to be notified. Since the present invention relates to “intrusion detection” by the image sensor 1, the response processing selection unit 203 when an intrusion detection signal is received from the image sensor 1 will be described in detail.

  FIG. 9 is a flowchart illustrating an example of an operation procedure of the response processing selection unit 203. When the response processing selection unit 203 receives the intrusion detection signal and the accumulated image (S301), it checks the intrusion detection level of the image sensor 1. When the intrusion detection by the image sensor 1 is the first level intrusion detection or the second level intrusion detection (S302; Yes), the response processing selection unit 203 sends the intrusion detection signal and the accumulated image to the monitoring center device 8. Transmit (S303). As a result, in the monitoring center, the monitoring person confirms whether or not a person has entered based on the image or the like, and performs necessary response processing.

  When the third level intrusion detection signal is received from the image sensor 1, the response processing selection unit 203 outputs an activation signal to the facility control unit 204 to activate the smoke generating device 3 (S304). If the third level intrusion detection is determined, the presence of the intruder is almost deterministic, and the smoke generating device 3 is immediately activated. Thereby, since it becomes possible to start a smoke generator immediately at the timing which detected the intruder, it becomes possible to start the smoke generator 3 effectively, without losing start timing. Therefore, the smoke generator 3 can be used effectively, and a remote monitoring device with higher crime deterrence can be provided. Thereafter, the process of step S303 is executed. Note that the order of steps S303 and S304 may be reversed.

  FIG. 11 is a flowchart showing another example of the operation processing procedure in the response processing selection unit 203. This operation processing procedure is characterized in that the latest image is transmitted to the monitoring center device 8 when the image sensor 1 detects the second level intrusion. That is, when the first level intrusion detection signal is received from the image sensor 1 (Yes in both S311 and S312), the stored image is transmitted to the monitoring center device 8 and the second level or third level intrusion detection signal is received. If it is done (S312; No), the process proceeds to step S314.

  Next, it is checked whether it is a second level intrusion detection signal (S314). If it is not the second level intrusion detection signal, that is, in the case of the third level intrusion detection (S314; No), the equipment control means 204 An activation signal for activating the smoke generating device 3 is output (S316). Further, in either case of the second level or the third level intrusion detection signal, the image sensor 1 is requested to transmit the latest image, and when the latest image is received from the image sensor 1, the latest image is transmitted to the monitoring center device 8. The communication processing of the latest image data is performed (S315). The transmission of the latest image is continued until the latest image transmission stop command is received from the monitoring center device 8. The process is continued until a current image data transmission stop command is received from the monitoring center device 8. Although omitted in this flowchart, when the level of the intrusion detection signal is determined (S312 and S314), if the intrusion detection signal of the same level is already stored in the storage unit 206 from the image sensor 1, Without processing, the process returns to step S311.

  In the present embodiment, when the third level intrusion detection signal is received, the smoke generating device 3 that is a threatening device is always driven. However, when the third level intrusion detection signal is received, the monitoring device 2 has already been monitored. If the current image is transmitted to the center device 8, the smoke generating device 3 may not be activated. For example, while the monitoring device 2 receives the second level intrusion detection signal from the image sensor 1 and transmits the current image to the monitoring center device 8 in step S315, the third level intrusion detection is detected from the image sensor 1. This is the case when a signal is received. In such a case, it is preferable to give priority to the judgment of the supervisor because the supervisor of the monitoring center sees the image from the image sensor 1. Therefore, the monitoring person transmits a start signal of the smoke generating device 3 from the monitoring center device 8 to the monitoring device 2 to start the smoke generating device 3. As a result, the smoke generating device 3 can be started with a more reliable determination than the determination by the image sensor 1.

  FIG. 12 is a diagram illustrating an example of data transmission / reception between devices of a remote monitoring system using the image sensor 1, the monitoring device 2, and the remote monitoring device (monitoring center device 8) illustrated in FIG. In FIG. 12, the monitoring apparatus 2 will be described as being set to the monitoring mode. The monitoring device 2 periodically transmits a status report request signal to the image sensor 1. On the other hand, the image sensor 1 transmits a normal signal as a response to the monitoring device 2 if there is no particular problem.

  Now, assuming that the image sensor 1 has received the first level intrusion detection signal, the first level intrusion detection signal is transmitted to the monitoring device 2. The monitoring device 2 that has received the first level intrusion detection signal transmits an abnormal signal including the first level intrusion detection signal to the monitoring center device 8. The image sensor 1 may be configured to transmit the accumulated image simultaneously with the first level intrusion detection signal, but in the present embodiment, the accumulated image is sent from the monitoring device 2 to the image sensor 1 as shown in FIG. It is configured to make a request. When the image sensor 1 receives the accumulated image request signal from the monitoring device 2, the image sensor 1 transmits the accumulated image to the monitoring device 2. The monitoring device 2 transmits the received accumulated image to the monitoring center device 8. If the monitoring person who monitors the monitoring center device 8 determines that the latest image is necessary for intrusion confirmation, the monitoring center device 8 requests the latest image. In response to this, the monitoring device 2 requests the image sensor 1 to transmit the latest image. Based on this, the latest image is transmitted from the image sensor 1 to the monitoring center device 8 via the monitoring device 2. If the monitoring staff of the monitoring center determines that the activation of the smoke generating device 3 is appropriate based on the received latest image or the like, the monitoring center device 8 transmits an activation signal of the smoke generating device 3 including the identification symbol. When receiving the activation signal of the smoke generating device 3, the monitoring device 2 activates the corresponding smoke generating device 3 with reference to the correspondence table (FIG. 10) of the storage unit 206 under the control of the facility control unit 204.

  The monitoring center transmits a monitor end signal to the monitoring device 2 when the corresponding processing for intrusion detection is completed. Based on this, the monitoring device 2 deletes the intrusion detection signal stored in the storage unit 206 and stops transmitting the latest image, and transmits a monitor end signal to the image sensor 1. Thereby, transmission of the latest image is stopped. The monitoring device 2 is stopped when it receives the latest image transmission stop command without receiving the monitor end signal. The image sensor 1 that has received the monitor end signal stops transmitting the latest image. This process is the same when a transmission stop command is received.

  The column below the broken line in FIG. 12 shows the corresponding processing when the image sensor 1 determines that the third level intrusion detection has occurred. When receiving the current status report signal, the image sensor 1 transmits a third level intrusion detection signal to the monitoring device 2. The monitoring device 2 transmits an abnormal signal including the third level intrusion detection signal to the monitoring center device 8 and transmits an activation signal for the smoke generating device 3 to the smoke generating device 3. When the smoke generating device 3 receives the activation signal, it smokes and blocks the intruder's field of view. Further, the latest image request signal is transmitted from the monitoring device 2 to the image sensor 1, and the latest image is transmitted to the monitoring center device 8 via the monitoring device 2. When the predetermined response process ends, a monitoring end signal is transmitted from the monitoring center device 8 to the monitoring device 2 and the image sensor 1. Thereby, transmission of the latest image is stopped.

  When the smoke generation device 3 is activated from the monitoring center device 8, an activation signal including an identification symbol is transmitted from the monitoring center device 8 to the monitoring device 2, and the monitoring device 2 refers to the correspondence table in FIG. Although the smoke generator 3 is specified and the smoke generator 3 is activated, the monitoring center device 8 stores a correspondence table of the monitor device 2 and transmits an activation signal for identifying the smoke generator 3 to the monitor device 2. It is good also as composition to do.
