Description

  The present invention relates to a building imaging system.

  In buildings such as houses, security cameras may be installed outdoors in consideration of security (for example, Patent Document 1). In buildings where security cameras are installed, a human detection sensor is usually provided to detect the presence of a person around the building, and based on the detection of the human by the human detection sensor, shooting by the security camera is to be performed. It is said. As a result, when a suspicious person appears in the vicinity of the building, the image is automatically taken, and the image of the photographed suspicious person is used as a clue to arrest the criminal.

JP 2005-94642 A

  By the way, intrusion into a building by a suspicious person may be performed from the entrance door when the entrance door is illegally unlocked (for example, picking), or may be performed from the window opening when the window is destroyed. In other words, there are various routes for the suspicious person to enter the building. For this reason, in order to reliably photograph a suspicious person existing around a building with an outdoor security camera, it is necessary to install a security camera at least around each opening that can be an entrance to the building. However, in this case, the number of security cameras to be installed increases, and as a result, the installation cost can be significantly increased. In addition, when installing a security camera outdoors, it is necessary to consider the effects of rain, wind, etc., and to make the security camera into an environmentally resistant structure such as a waterproof structure. Is assumed.

  On the other hand, even if a security camera is installed around each opening, there may be a case where a suspicious person cannot be photographed accurately due to the influence of weather or the like during photographing. For example, it is assumed that such inconvenience arises when heavy rain falls at the time of shooting or when the sun is shining. Further, it is conceivable that some suspicious persons may prevent the camera from taking a picture by covering the lens of the security camera with a cloth or the like. In that case, it becomes impossible to photograph the suspicious person.

  The present invention has been made in view of the above circumstances, and a main object of the present invention is to provide a building photographing system capable of photographing a suspicious person more reliably while reducing the installation cost. .

  In order to solve the above-described problem, the building photographing system according to the first aspect of the present invention is provided with an exit detection means for detecting that a person is about to exit from the building through the entrance of the building, and is provided indoors so as to exit through the entrance. A photographing means for photographing the person being photographed, and a control means for performing photographing by the photographing means when the exit detecting means detects that the person is about to leave.

  As described above, when a suspicious person enters the building, it enters through a doorway (such as a doorway) where people can enter and exit, and through a window opening when the door of the doorway is locked. It is possible. On the other hand, when a suspicious person who has entered the building exits the building, the door can be unlocked from the indoor side, so it is assumed that the suspicious person will exit through the doorway without leaving the window opening. Is done. Therefore, in the present invention, focusing on this point, when a person who intends to leave the entrance / exit is detected by the exit detection means, photographing is performed by the photographing means provided on the indoor side. Thereby, since it can image | photograph aiming at the place where the suspicious person who penetrate | invaded in the building is going to leave through an entrance, a suspicious person can be image | photographed more reliably. In addition, since the intruder can be photographed without installing a large number of photographing means, the installation cost can be reduced. Therefore, it is possible to capture the suspicious person more reliably while reducing the installation cost.

  In addition, since the photographing means is installed indoors, it is possible to photograph a suspicious person relatively without being affected by the weather or the like. From this point of view, it is expected that the suspicious person can be photographed more reliably. Furthermore, unlike the case of outdoor installation, it is not necessary for the photographing means to have an environment-resistant structure, so that the installation cost can also be reduced in this respect.

  In the building photographing system according to the second invention, in the first invention, the entrance door for opening and closing the entrance is provided with a handle on the indoor side, and the exit detection means indicates that a person has contacted the handle. It is the contact detection means to detect, It is characterized by the above-mentioned.

  When a person exits the building through the entrance, the entrance door is opened to exit. In this case, the door is usually opened with a handle provided on the indoor side of the door. Therefore, in the present invention, focusing on this point, it is detected that the person is about to leave the building through the doorway by detecting that the person has touched the handle by the contact detection means. Thereby, it can be specifically detected that a person is about to leave through the entrance.

  In addition, when the handle is of a rotating type, when a person exits the building through the doorway, it is usual to rotate the handle in the opening direction to open the doorway. Therefore, paying attention to this point, it is also possible to provide a rotation detection means for detecting that the handle is rotated in the opening direction, and to use the rotation detection means as the exit detection means. This also makes it possible to specifically detect that a person is about to leave through the doorway.

  In the building photographing system according to a third invention, in the first invention, the exit detection means is an unlocking detection means for detecting that an entrance door for opening and closing the entrance is unlocked from the indoor side. It is characterized by.

  When a person leaves the building through the doorway, the doorway is unlocked from the indoor side, and then the doorway is opened. Therefore, in the present invention, paying attention to this point, when the unlock detection means detects that the door has been unlocked, it detects that a person is about to leave the building through the door. . Thereby, it can be specifically detected that a person is about to leave through the entrance.

  The building imaging system according to a fourth aspect of the present invention is the identification information in which the identification information of the portable device carried by the user is acquired in any one of the first to third aspects, and the acquired identification information is registered in advance. Authentication means for authenticating whether or not they match, and when the identification information is authenticated by the authentication means, the control means uses the photographing means regardless of the detection result of the exit detection means. It is characterized by not taking a picture.

  According to the present invention, when the identification information is authenticated based on the identification information acquired from the portable device carried by the user, the photographing by the photographing unit is performed regardless of the detection result by the exit detection unit. Not. That is, when the person who is about to leave outdoors through the doorway is a user (for example, a resident) who possesses a portable device, photographing by the photographing means is not performed. Therefore, unintended useless shooting can be avoided as much as possible.

  According to a fifth aspect of the present invention, there is provided a building photographing system according to the fourth aspect of the present invention, further comprising portable determining means for determining whether or not the portable device is being carried by a user. When it is determined that the machine is not carried by the user, the photographing by the photographing unit is performed even when the authentication by the authentication unit is performed.

  According to the present invention, when it is determined by the portable determination means that the portable device is not carried by the user, photographing by the photographing means is performed regardless of authentication of identification information from the portable device. As a result, the user is authenticated based on identification information from a portable device that is not portable, for example, a portable device left in the building, so that suspicious persons who are about to leave the building are not photographed. Inconvenient situations can be avoided.

  A building imaging system according to a sixth aspect of the present invention is the person who intrudes into the building through an opening other than the entrance / exit among the plurality of openings communicating with the inside and outside of the building in any one of the first to fifth inventions. Intruder detection means for detecting the intruder, and the control means performs photographing by the photographing means on condition that an intruder is detected by the intruder detection means.

  According to the present invention, photographing by the photographing means is performed only when a person who has entered the building through an opening other than the entrance is detected by the intruder detection means among the plurality of openings in the building. Here, “entrance / exit” means an opening where a person can enter and exit, such as a doorway or a doorway, and “an opening other than the entrance / exit” means an opening such as a window opening where a person does not normally enter or exit. To do. In other words, in the present invention, a person who has entered the building through an opening where a normal person does not enter and exit is regarded as a suspicious person, and photographing is performed on the condition that such a suspicious person has been detected. Therefore, since no shooting is performed unless a suspicious person is detected, unintended useless shooting can be avoided every time a user such as a resident exits the entrance / exit.

  According to a seventh aspect of the present invention, there is provided a building photographing system including at-home determination means for determining whether a resident is at home in any one of the first to sixth aspects, wherein the control means is the at-home determination means. On the condition that it is determined that the resident is absent, photographing by the photographing means is performed.

  According to the present invention, the photographing by the photographing unit is performed only when the resident determination unit determines that the resident is absent. That is, since shooting is performed only when the building is in an absence state, it is possible to avoid shooting when a resident in the building exits outdoors through the entrance. This can reduce unintended useless shooting.

  According to an eighth aspect of the present invention, there is provided a building photographing system according to any one of the first to seventh aspects of the present invention, based on a storage means for storing an image photographed by the photographing means and an image photographed by the photographing means. User determining means for determining whether or not the person who has been registered is a pre-registered user, and when the user determining means determines that the registered user is a registered user, the captured image is stored in the storage means It is characterized by not memorizing.

  According to the present invention, when it is determined that the person photographed by the photographing unit is a registered user, the photographed image is not stored in the storage unit. Therefore, even if the photographing unit performs photographing every time the user exits the building through the entrance / exit, it is possible to prevent those photographed images from being stored in the storage unit.

The top view which shows the entrance periphery. 1 is an overall configuration diagram showing a photographing system. The flowchart which shows the control processing of a controller.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view showing the vicinity of the entrance.

  As shown in FIG. 1, the building 10 includes an entrance hall 11 as an indoor space, and a corridor 12 and a living room 13 provided adjacent to the entrance hall 11. The building 10 is provided with an entrance 15 that communicates the entrance hall 11 with the outside, and the entrance 10 can be entered and exited through the entrance 15. An entrance door 16 is provided at the entrance 15. The entrance door 16 is, for example, a rotary door, and the entrance door 15 is opened and closed by turning the entrance door 16. The entrance door 16 is provided with a locking / unlocking device 17. The locking / unlocking device 17 is a device that locks and unlocks (locks and unlocks) the front door 16 by electrically locking and unlocking the lock. The locking / unlocking device 17 executes a locking / unlocking process based on an ID code signal as identification information transmitted from the electronic key 18 carried by the resident.

  The entrance door 16 is provided with a knob 21 on each of the indoor side and the outdoor side. The knob 21a on the indoor side is provided with a knob contact sensor 22 as contact detection means. The knob contact sensor 22 is a sensor that detects that a person has touched the indoor knob 21a, and is configured by a known touch sensor or the like. The knob contact sensor 22 is built in, for example, the indoor knob 21a.

  A communication unit 25 is provided in the entrance hall 11. The communication unit 25 is provided, for example, on the ceiling of the entrance hall 11. The communication unit 25 performs wireless communication with the electronic key 18 possessed by the resident. The communication unit 25 is set so that its communication area includes at least the entrance hall 11, and can communicate with the electronic key 18 in the area. Therefore, when the user who possesses the electronic key 18 leaves the building 10 through the entrance 15, communication is performed between the electronic key 18 and the communication unit 25 in the entrance hall 11.

  In the entrance hall 11, a surveillance camera 23 is installed as a photographing means. The surveillance camera 23 is composed of a digital camera, and is installed on the inner wall of the entrance hall 11 beside the entrance door 16. In the present embodiment, it is possible to photograph from the front a person who faces the entrance 15 in the entrance hall 11, for example, a person who is about to leave the building 10 through the entrance 15 by the monitoring camera 23. ing. More specifically, the surveillance camera 23 can photograph at least the face of a person who is about to leave through the entrance 15.

  The building 10 is provided with an indoor device 30 for managing the photographing system. The indoor device 30 is installed on a partition wall with the entrance hall 11 in the living room 13, for example. Hereinafter, the electrical configuration of the imaging system will be described with reference to FIG. FIG. 2 is an overall configuration diagram showing the photographing system.

  As shown in FIG. 2, the indoor device 30 includes a controller 31 as a control means, a display unit 32 including a liquid crystal display, and an operation unit 33 operated by a resident. A display unit 32 and an operation unit 33 are connected.

  The controller 31 controls photographing of the monitoring camera 23 in the photographing system, and includes a known microcomputer having a CPU and the like. The controller 31 has an ID code storage unit 36 that stores ID code information as identification information.

  A knob contact sensor 22 is connected to the input side of the controller 31. When a person touches the indoor knob 21 a by gripping the indoor knob 21 a of the entrance door 16, a detection signal is input from the knob contact sensor 22 to the controller 31.

  A monitoring camera 23 is connected to the controller 31. The controller 31 outputs a photographing signal to the monitoring camera 23 based on the detection signal from the knob contact sensor 22. Thereby, imaging | photography is performed by the surveillance camera 23. FIG. When shooting is performed by the monitoring camera 23, captured images are sequentially input from the monitoring camera 23 to the controller 31 as digital image information.

  The controller 31 has an image storage unit 37 as storage means. The image storage unit 37 stores an image taken by the monitoring camera 23. The image storage unit 37 is configured by, for example, a nonvolatile memory, and can store thousands of images. When image information is input from the monitoring camera 23 to the controller 31, the controller 31 stores the image information in the image storage unit 37 each time. In addition, the image storage unit 37 stores image information from the monitoring camera 23 in association with the shooting date and time. Thereby, it can be grasped when each image stored in the image storage unit 37 is taken. Note that the image stored in the image storage unit 37 is only a predetermined number (for example, 1,000), and when the predetermined number of images is stored, the image with the oldest shooting date is overwritten and deleted.

  Each image stored in the image storage unit 37 is displayed on the display unit 32 based on an operation on the operation unit 33 by the user. Thereby, the resident can confirm each image image | photographed with the surveillance camera 23. FIG. The operation unit 33 is provided with various operation buttons. For example, a delete button for deleting an unnecessary image from the image storage unit 37 or each image stored in the image storage unit 37 is sequentially displayed on the display unit 32. A feed button, a return button, and the like for displaying are provided. Moreover, in this embodiment, the non-volatile memory which comprises the image memory | storage part 37 can be removed from the indoor apparatus 30, and the removed memory can be connected to an external apparatus. Therefore, for example, the captured image can be displayed on a television set or the like provided in a room other than the living room 13 to confirm the image.

  A communication unit 25 is connected to the controller 31. When a detection signal is input from the knob contact sensor 22, the controller 31 transmits a request signal to the communication area via the communication unit 25. Here, when the user who possesses the electronic key 18 is in the communication area, the request signal is received by the electronic key 18, and the electronic key 18 transmits the ID code signal as a response to the request signal. When the communication unit 25 receives the ID code signal, the ID code signal is input from the communication unit 25 to the controller 31.

  ID code information as identification information is stored in advance in the ID code storage unit 36 of the controller 31. The ID code stored in the ID code storage unit 36 corresponds to the ID code stored in the electronic key 18. When an ID code signal is input from the electronic key 18, the controller 31 performs ID code authentication. Specifically, the controller 31 determines whether or not the input ID code signal matches the ID code stored in the ID code storage unit 36.

  Next, photographing control processing executed by the controller 31 will be described based on the flowchart shown in FIG. This process is repeatedly executed at a predetermined cycle.

  First, in step S11, based on the detection signal from the knob contact sensor 22, it is determined whether or not a person has touched the indoor knob 21a of the entrance door 16. That is, it is determined here whether or not a person is about to leave the room through the entrance 15. When a person is not touching the indoor knob 21a, this process is terminated. On the other hand, if the person is not touching the indoor knob 21a, the process proceeds to step S12.

  In step S12, a request signal is transmitted from the communication unit 25 to a predetermined communication area.

  In a succeeding step S13, it is determined whether or not the ID code signal transmitted from the electronic key 18 as a response to the request signal is received via the communication unit 25. If an ID code signal has not been received from the electronic key 18, the process proceeds to step S15. If an ID code signal has been received, the process proceeds to step S14.

  In step S <b> 14, it is determined whether the ID code signal received from the electronic key 18 matches the ID code stored in advance in the ID code storage unit 36. If the ID code signal from the electronic key 18 matches the ID code stored in the ID code storage unit 36, this process is terminated. That is, in this case, since it is possible to determine that the person who is about to leave through the entrance 15 is a user, the present process is terminated without performing shooting by the monitoring camera 23. On the other hand, if the ID code signal from the electronic key 18 does not match the ID code in the ID code storage unit 36, the process proceeds to step S15.

  In step S15, an imaging signal is output to the surveillance camera 23. As a result, the monitoring camera 23 performs shooting, and a person who is about to leave the room through the entrance 15 can be shot.

  In step S <b> 16, the image captured in step S <b> 15 is captured from the monitoring camera 23.

  In step S17, it is determined whether or not the image storage unit 37 has a free space. Specifically, it is determined whether or not there is a free capacity capable of storing one image (one image). If there is free space in the image storage unit 37, the process proceeds to step S19. If there is no free space in the image storage unit 37, the process proceeds to step S <b> 18, and the image with the oldest shooting date is deleted from the images stored in the image storage unit 37. As a result, a new image can be stored in the image storage unit 37.

  In step S19, the image information captured in step S16 is stored in the image storage unit 37. Thereafter, this process is terminated.

  As mentioned above, according to the structure of this embodiment explained in full detail, the following outstanding effects are acquired.

  When the knob contact sensor 22 detects that a person has contacted the indoor side knob 21a of the entrance door 16, photographing is performed by the monitoring camera 23 installed in the entrance hall 11. That is, when it is detected that a person is about to leave the entrance hall 11 through the entrance 15, the surveillance camera 23 performs shooting. Thereby, since the suspicious person who entered the building 10 can take a picture aiming to leave through the entrance 15, the suspicious person can be photographed more reliably. In addition, since the intruder can be photographed without installing a large number of surveillance cameras 23, the installation cost can be reduced. Therefore, it is possible to capture the suspicious person more reliably while reducing the installation cost.

  In addition, since the surveillance camera 23 is installed indoors, it is possible to photograph a suspicious person without being relatively affected by the weather or the like. From this point, it can be expected that the suspicious person can be photographed more reliably. Furthermore, unlike the case of outdoor installation, the surveillance camera 23 does not need to have an environment-resistant structure, so that the installation cost can be reduced also from this point.

  A knob contact sensor 22 for detecting that a person has touched the indoor side knob 21 a of the entrance door 16 is provided, and based on the detection result of the knob contact sensor 22, photographing by the monitoring camera 23 is performed. Thereby, it can be specifically detected that a person is about to leave the building 10 through the entrance 15.

  When the ID code is authenticated on the basis of the ID code signal from the electronic key 18, the monitoring camera 23 is not photographed regardless of the detection result by the knob contact sensor 22. As a result, when the person who is about to leave the building 10 through the entrance 15 is a user carrying the electronic key 18, shooting by the surveillance camera 23 is not performed, and therefore unintended useless shooting is avoided as much as possible. Can do.

  The present invention is not limited to the above embodiment, and may be implemented as follows, for example.

  (1) In the above embodiment, it is configured to detect that a person is about to leave the room through the entrance 15 based on the detection signal from the knob contact sensor 22, but this is changed as follows. Also good. For example, a rotation detection sensor that detects that the indoor knob 21a is turned in the opening direction may be provided, and it may be detected that a person is about to leave based on a detection signal from the sensor. Further, an unlock detection sensor for detecting that the unlocking device 17 of the entrance door 16 has been unlocked from the entrance hall 11 side is provided on the entrance door 16, and a person is about to leave based on a detection signal from the sensor. May be detected. These can also specifically detect that a person is about to leave the building 10 through the entrance 15.

  (2) Generally, the building 10 is provided with a plurality of openings that communicate indoors and outdoors. As the opening, an opening such as the entrance 15 that allows people to enter and exit is provided, and an opening such as a window opening that does not allow normal people to enter and exit is provided. Therefore, for example, an intrusion detection sensor that detects a person who enters the building 10 through the window opening is provided around the window opening in the building 10 and is photographed by the monitoring camera 23 on the condition that the intruder is detected by the sensor. May be implemented. Here, the intrusion detection sensor includes, for example, a human sensor that detects a person. Thereby, unless the intruder is detected, photographing by the monitoring camera 23 is not performed. Therefore, it is possible to avoid unintended photographing every time a user such as a resident exits the entrance 15.

  (3) At-home determination means for determining whether or not a resident is at home is provided in the building 10, and photographing by the surveillance camera 23 is performed on the condition that the resident is determined to be absent by the at-home determination means. May be implemented. Here, as the at-home determination means, for example, a receiving unit for receiving an ID code signal transmitted from the electronic key 18 is provided in the building 10, and a resident is at home based on the ID code received through the receiving unit. It can be considered to determine whether or not. In this case, since shooting is performed by the monitoring camera 23 only when the inside of the building 10 is in an absence state, it is avoided that the shooting is performed when a resident in the building 10 leaves the doorway 15 through the doorway 15. can do. This can reduce unintended useless shooting. In addition, when a visitor or the like is visiting the building 10, it is possible to avoid shooting when the visitor or the like exits the building 10 through the entrance 15.

  (4) In the above embodiment, the image captured by the monitoring camera 23 is stored in the image storage unit 37 each time, but this may be changed. For example, the controller 31 is provided with a user determination unit that determines whether the photographed person is a pre-registered user based on an image captured by the monitoring camera 23, and the user determination unit is a registered user. If it is determined, the image may not be stored in the image storage unit 37. By doing so, even when the user takes a picture with the monitoring camera 23 every time the user leaves the building 10 through the entrance 15, the user images can be prevented from being accumulated in the image storage unit 37. .

  (5) Further, the identification means for identifying the person of each image based on the image stored in the image storage unit 37 and the same as each image stored in the image storage unit 37 based on the identification result by the identification means An image determination unit that determines whether or not a person's image is included, and when the image determination unit determines that the image of the same person is included, the image storage unit stores the image of the same person You may make it delete from 37. Usually, a user such as a resident enters and exits the building 10 many times, but it is unlikely that a suspicious person repeatedly enters the same building 10. Therefore, when images of the same person are stored in the image storage unit 37, it is appropriate to regard these images as user images. That is, according to this configuration, it is possible to suppress accumulation of unnecessary images in the image storage unit 37 by deleting the user image stored in the image storage unit 37.

  (6) In the above embodiment, the surveillance camera 23 is installed in the entrance hall 11 so as to photograph a person who is about to exit from the interior through the entrance 15. A monitoring camera 23 may be installed in the camera to take a picture of a person who is about to leave the entrance. When a plurality of entrances / exits are provided in the building 10, a monitoring camera 23 may be installed at each entrance / exit. However, in order to reduce the installation cost, it is desirable that the number of surveillance cameras 23 to be installed is smaller.

  (7) In the above embodiment, authentication is performed to determine whether the ID code signal transmitted from the electronic key 18 matches the ID code stored in the ID code storage unit 36. Although the photographing by the monitoring camera 23 is not performed, this may be changed as follows.

  A portable determining means for determining whether or not the electronic key 18 is carried by the user is provided, and when the electronic key 18 is determined to be non-carried by the determining means, the ID code from the electronic key 18 is Regardless of the authentication result, photographing by the monitoring camera 23 may be performed. Accordingly, the user is authenticated based on the ID code signal from the electronic key 18 that is not carried by the user, for example, the electronic key 18 that is left in the building 10, so that a suspicious person who is about to leave the building 10 can be identified. On the other hand, it is possible to avoid an inconvenient situation where shooting is not performed.

  Here, as the portable determination means, for example, a vibration sensor that detects that the electronic key 18 vibrates is provided in the electronic key 18, and the electronic key 18 moves with the user based on the detection result of the vibration sensor. In other words, it may be determined that the electronic key 18 is carried by the user.
