  Hereinafter, a water discharge control system and a water discharge control device of an embodiment will be described with reference to the drawings.

<First Embodiment>
First, the first embodiment will be described.
FIG. 1 is a block diagram illustrating a configuration example of a water discharge control system 1 according to the first embodiment. The water discharge control system 1 controls water discharge and water stop based on the image of the imaging target area 40 that is an area including the graphic 401. The figure 401 is, for example, a visual symbol (pictogram) corresponding to the operation in the water discharge state. Here, the graphic 401 is an example of a “display unit”.

  As shown in FIG. 1, a graphic 401 is an image showing, for example, a pictograph of a cup in which water has been poured. The pictogram of the cup into which water is poured corresponds to, for example, an operation in a water discharge state of discharging purified water.

  The figure 401 is not an electronic component in which a touch sensor or an electronic circuit is incorporated, but is a member on which a visual symbol (pictogram) is drawn, for example, a sticker, a sticker, a card, or the like. Moreover, although the case where the figure 401 is one was illustrated in FIG. 1, there may be a plurality of figures 401. The graphic 401 may be provided at any location suitable for operating the water discharge state, such as a sink wall or an outer peripheral portion, and the display position (hereinafter also simply referred to as “position”) is not fixed. The position may be changed accordingly. For example, when a small child uses a water faucet, the figure may be moved to a lower position for use.

  The water discharge state is a state relating to water to be discharged, such as the type of water to be discharged, the form of water to be discharged, the water pressure and flow rate of water to be discharged, the temperature and the like. Examples of the water discharged include raw water, purified water, and hot water. Examples of the form of water discharged include straight water discharge and shower water discharge. In the following description, a case where the water discharge control system 1 controls water discharge and water stop will be described as an example. The type of water to be discharged may include so-called functional water such as purified hot water, carbonated water, sterilized water, and alkaline ionized water. Moreover, the water discharge state may include the temperature, water pressure, and amount of water discharged.

  The water discharge control system 1 includes, for example, an imaging device 10 and a water discharge control device 20. The water discharge control device 20 is connected to an electromagnetic valve 30 that starts or ends water discharge from the water discharge pipe. The water discharge control system 1 controls water discharge and water stoppage of the water discharge pipe by opening and closing the electromagnetic valve 30.

  The imaging device 10 is provided in a place where water is used, such as a kitchen, and images the imaging target region 40 at a predetermined time interval. Here, the image of the imaging target area 40 captured by the imaging apparatus 10 is an example of an “area image”. For example, the imaging device 10 captures an area wider than the sink (for example, an area including the sink and the stove). The imaging device 10 is provided, for example, on the ceiling of a kitchen or the outer surface of the bottom plate of a wall cabinet. In the case of being provided on the ceiling, a bulb-type camera that can be attached to the lighting wiring apparatus can be used. In this case, the imaging device 10 operates with electric power supplied from the illumination wiring device. In this case, the imaging device 10 is provided in the upper direction of the water discharge pipe. In this case, for example, the imaging device 10 is installed such that an area viewed from the upper side of the water discharge pipe is the imaging area. That is, the imaging device 10 images a region including the water discharge pipe from a position overlooking the water discharge pipe.

  Further, the imaging device 10 outputs image information of the captured image to the water discharge control device 20. The imaging device 10 outputs image information of the captured image to the water discharge control device 20 via a wireless communication line such as WiFi (Wi-Fi), for example. Note that the imaging device 10 may capture a moving image or a still image. The imaging device 10 may capture a color image or a monochrome image.

  The water discharge control device 20 includes, for example, a target object detection unit 200, a graphic detection unit 201, a coordinate extraction unit 202, a coordinate extraction unit 203, and a coincidence detection unit 204. Here, the target object detection unit 200 and the coordinate extraction unit 202 are examples of a “target object detection unit”. The graphic detection unit 201 and the coordinate extraction unit 203 are examples of a “display detection unit”. The coincidence detection unit 204 is an example of a “control unit”.

  The target object detection unit 200 detects whether or not the target object 400 is present in the image based on the image of the imaging target region 40 captured by the imaging device 10. The target object 400 here is an object to be detected by the target object detection unit 200 and is an object that operates the figure 401. The target object is, for example, a part of a human hand that pushes, touches, or points to the graphic 401.

  The target object detection unit 200 extracts various objects captured in an image by performing edge detection, for example. The target object detection unit 200 performs edge detection based on, for example, the luminance difference in the image data. Specifically, the figure detection unit 201 assigns various rectangular frames (cells) to the image, and when there is a small difference in luminance on the outer periphery of the frame compared to the inside of the frame, the object is within the frame. It is determined that there is an object, and an object is extracted from the image by extracting the frame.

  The target object detection unit 200 selects a portion of the target object 400 from the objects extracted from the image. For example, the target object detection unit 200 stores in advance images indicating the shapes of various parts of the body such as various hands, fingers, and elbows (hereinafter simply referred to as “hands”) that are assumed to be operations. deep. The target object detection unit 200 scales the stored hand image and the object image extracted from the image captured by the imaging device 10 to the same size, and compares each pixel of both images. To do. The target object detection unit 200 determines that the object extracted from the image is the image of the target object 400 when both the compared images satisfy a predetermined similarity condition. The predetermined similarity condition here is, for example, a case where the ratio of pixels in which the color difference between the pixels in both images is less than a predetermined threshold is a predetermined ratio or more. The target object detection unit 200 outputs the detection result to the coordinate extraction unit 202.

  The graphic detection unit 201 detects whether or not there is a graphic 401 in the image based on the image of the imaging target area 40 captured by the imaging device 10.

  The graphic detection unit 201 extracts various objects captured in an image by performing edge detection, for example. Then, the graphic detection unit 201 selects the graphic 401 from the object extracted from the image. For example, the graphic detection unit 201 stores a predetermined graphic 401 in a graphic storage unit (not shown) in advance. The graphic detection unit 201 compares the stored graphic 401 with the image of the object extracted from the image captured by the imaging device 10, and the object extracted from the image when both images satisfy a predetermined similarity condition Is a figure 401. The figure detection unit 201 outputs the detection result to the coordinate extraction unit 203.

  The coordinate extraction unit 202 extracts position coordinates indicating the position of the target object 400 based on the image captured by the imaging device 10 and the detection result output by the target object detection unit 200. The position coordinates here may be a coordinate value (representative value) indicating a position near the center in the portion of the target object 400, or a coordinate group indicating the outer periphery of the target object 400. The coordinate extraction unit 202 outputs the position coordinates of the target object 400 in the extracted image to the coincidence detection unit 204.

  The coordinate extraction unit 203 extracts position coordinates indicating the position of the graphic 401 in the image based on the image captured by the imaging device 10 and the detection result output by the graphic detection unit 201. The coordinate extraction unit 202 outputs the position coordinates of the graphic 401 in the extracted image to the coincidence detection unit 204.

  The coincidence detection unit 204 detects whether or not the position coordinates of the target object 400 extracted by the coordinate extraction unit 202 match the position coordinates of the graphic 401 extracted by the coordinate extraction unit 203. For example, when the distance between the position coordinate of the target object 400 and the position coordinate of the figure 401 is less than a predetermined threshold, the coincidence detection unit 204 determines that both position coordinates coincide. The predetermined threshold here may be arbitrarily set according to the position where the figure 401 is installed.

  When the coincidence detection unit 204 determines that the position coordinates of the target object 400 match the position coordinates of the figure, the coincidence detection unit 204 determines that an operation of opening (or closing) the electromagnetic valve 30 has been performed. The control information shown is output to the solenoid valve 30.

  FIG. 2 is a diagram illustrating an example of a graphic 401 according to the first embodiment. Here, the figure 401 used for the water discharge control system 1 (1A) is demonstrated using FIG.

  Fig.2 (a) is the figure 401a corresponding to the operation of discharging raw water. FIG. 2B is a figure 401b corresponding to each of the raw water shower water discharge, raw water straight water discharge, clean water discharge, and water temperature adjustment operation. FIG.2 (c) is the figure 401c corresponding to each of the operation of discharging raw water and the operation of discharging purified water. FIG. 2D is a push button switch type graphic 401d corresponding to each of the operation of discharging raw water and the operation of discharging purified water. 3A to 3D, the symbol “+ (plus)” corresponds to the operation for increasing the water temperature, and the symbol “− (minus)” corresponds to the operation for decreasing the water temperature.

  As shown in FIGS. 2A to 2C, the graphic 401 (graphics 401a to 401d) may be an image corresponding to each operation content, or a comprehensive operation combining a plurality of operations. It may be an image corresponding to the content. That is, the figure 401 may be arbitrarily provided according to the water discharge state that can be operated in the water discharge pipe. In addition, the figure 401 may be arbitrarily selected according to the preference and situation of the human being operated. For example, when a young child or an elderly person operates, a figure 401 having a color or shape that can be easily recognized by the eyes of the child or the elderly may be used. In the figure 401 that is assumed to be operated by such a child or an elderly person, the temperature of hot water to be discharged is prevented from being excessively high, or the water pressure to be discharged is not excessively increased. You may make it perform control suitable for the situation of the person who does.

  Further, as shown in FIG. 2D, the figure 401 may include a figure having a texture or a shape in which the sense of operation is easily recognized by a human hand. By using such a figure 401, it becomes possible to make the operation of operating the water discharge state more natural.

If the graphic 401 as shown in FIG. 2 is realized by an electronic component in which a touch sensor or an electronic circuit is incorporated, it is necessary to provide the electronic component on the sink side, which is costly, and the graphic once set It is difficult to change the position of 401.
In the water discharge control system 1 of the present embodiment, the figure 401 can be provided at an arbitrary location as long as it is within the imaging target area 40, and the installation position of the figure 401 can be freely changed. . For this reason, it is possible to customize the operation so as to be easy according to the situation of the operating human.

  Note that the graphic 401 is not limited to the example of FIG. 2 and may be arbitrarily selected by an operating person. For example, the graphic 401 may be an image of a handwritten by a human being operated, a photograph of a family such as a human child who is operating, or an image of a favorite photograph. In this case, the graphic detection unit 201 stores a graphic 401 selected by the operating person in advance in a graphic storage unit (not shown). Thereby, the figure detection part 201 can detect the arbitrary figures 401 selected by the person who operates.

Here, the overall flow of the operation of the water discharge control device 20 will be described.
First, the water discharge control device 20 acquires image information of an image of the imaging target region 40 imaged by the imaging device 10. The water discharge control device 20 outputs the acquired image information to the target object detection unit 200 and the graphic detection unit 201.
Next, the target object detection unit 200 detects whether or not the target object 400 is included in the image. The target object detection unit 200 outputs the detection result to the coordinate extraction unit 202. The coordinate extraction unit 202 extracts the position coordinates of the target object 400 and outputs the extracted position coordinates to the coincidence detection unit 204.
Next, the graphic detection unit 201 detects whether or not the graphic 401 is included in the image. The figure detection unit 201 outputs the detection result to the coordinate extraction unit 203. The coordinate extraction unit 203 extracts the position coordinates of the graphic 401 and outputs the extracted position coordinates to the coincidence detection unit 204.
Then, the coincidence detection unit 204 controls water discharge by generating control information for opening and closing the electromagnetic valve 30 based on the position coordinates extracted by each of the coordinate extraction units 202 and 203.

  As described above, the water discharge control device 20 according to the first embodiment uses the image information of the region image in which the imaging target region 40 including the graphic 401 corresponding to the operation in the water discharge state, which is a state related to water to be discharged, is captured. Based on the figure detection unit 201 that detects the figure 401 in the region image, the target object detection unit 200 that detects the target object 400 based on the region image, the position of the figure 401 detected by the figure detection unit 201, and Based on the position of the target object 400 detected by the target object detection unit 200, a coincidence detection unit 204 that controls the water discharge state is provided. Thereby, the water discharge control device 20 of the first embodiment recognizes whether or not the operation of the water discharge state has been performed according to the positional relationship with the target object 400 detected based on the region image, and discharges water. Water discharge control that can be started or stopped is possible. For this reason, water discharge can be controlled without incorporating a camera or a sensor circuit in the faucet fitting.

Moreover, in the water discharge control apparatus 20 of embodiment, the installation position of the figure 401 can be changed. Thereby, the water discharge control apparatus 20 of embodiment can install the figure 401 in arbitrary positions according to the water discharge state which can be operated, and the condition of the person who operates. Moreover, since the figure 401 does not require electrical connection, it is very easy to change the installation position.
In the water discharge control device 20 of the embodiment, the water discharge state indicates at least one of the type of water to be discharged and the form of water to be discharged, and the type of water to be discharged is any of raw water, purified water, or hot water. Yes, the form of water discharged is either straight water discharge or shower water discharge. Thereby, the water discharge control device 20 of the embodiment can control the type of water discharged and the form of water discharged according to the operation.
In addition, the water discharge control system 1 of the embodiment includes an imaging device 10 that captures a region image including a graphic corresponding to a water discharge state operation that is a state related to water to be discharged, and image information of the region image captured by the imaging device 10. The water discharge control device 20 that acquires Thereby, since the water discharge control system 1 of embodiment can control water discharge based on the image imaged by the imaging device 10, it controls water discharge without incorporating a camera or a sensor circuit in the faucet fitting. Can do.

  FIG. 3 is a block diagram illustrating a configuration example of a water discharge control system 1A according to the second embodiment. The water discharge control device 20A of the water discharge control system 1A includes a selection unit 205 and a position information storage unit 206. Here, the selection unit 205 is an example of a “control unit”.

  When the figure detection unit 201 detects the figure 401, the coordinate extraction unit 203 extracts the position coordinates of the figure 401, stores the extracted position coordinates in the position information storage unit 206, and information indicating the extracted position coordinates Is output to the selection unit 205. On the other hand, when the graphic 401 is not detected by the graphic detection unit 201, the coordinate extraction unit 203 outputs information indicating that the graphic 401 is not detected to the selection unit 205.

  Based on the information output from the coordinate extraction unit 203, the selection unit 205 is either the position coordinate of the graphic 401 extracted by the coordinate extraction unit 203 or the position coordinate of the graphic 401 stored by the position information storage unit 206. Select. Specifically, the selection unit 205 is extracted by the coordinate extraction unit 203 when the position coordinates of the graphic 401 are extracted by the coordinate extraction unit 203, that is, when the graphic detection unit 201 detects the graphic 401. The position coordinates of the figure 401 are selected. On the other hand, when the information indicating that the figure 401 is not detected is output by the coordinate extraction unit 203, the selection unit 205 selects the position coordinates of the figure 401 stored by the position information storage unit 206. The selection unit 205 outputs the position coordinates of the selected graphic 401 to the coincidence detection unit 204.

  The position information storage unit 206 stores information indicating the position coordinates of the graphic 401 output by the coordinate extraction unit 203.

  FIG. 4 is a flowchart illustrating an operation example of the water discharge control device 20A according to the second embodiment. Here, the overall flow of the operation of the water discharge control device 20A will be described with reference to FIG.

First, the water discharge control device 20A acquires image information of an image of the imaging target region 40 imaged by the imaging device 10 (step S100). The water discharge control device 20 </ b> A outputs the acquired image information to the target object detection unit 200 and the graphic detection unit 201.
Next, the graphic detection unit 201 performs a process of detecting whether or not the graphic 401 is included in the image (graphic detection process) (step S200). The figure detection unit 201 outputs the detection result to the coordinate extraction unit 203.
Next, the coordinate extraction unit 203 performs a process (graphic position storage process) of extracting the position coordinates of the graphic 401 and storing the extracted position coordinates in the position information storage unit 206 (step S300). The coordinate extraction unit 203 outputs the extracted position coordinates of the figure 401 to the selection unit 205. In addition, when the graphic detection unit 201 does not detect the graphic 401, the coordinate extraction unit 203 outputs information indicating that to the selection unit 205.
Next, the target object detection unit 200 performs processing (operation detection processing) for detecting whether or not an operation (for example, the target object 400) for the graphic 401 is included in the image (step S400). The target object detection unit 200 outputs the detection result to the coordinate extraction unit 202. The coordinate extraction unit 202 extracts the position coordinates of the target object 400 based on the detection result output by the target object detection unit 200, and outputs the extracted position coordinates to the coincidence detection unit 204.
Then, the coincidence detection unit 204 and the selection unit 205 store the result of processing (operation detection processing) by the target object detection unit 200 and the position coordinates of the graphic 401 extracted by the coordinate extraction unit 203 (graphic position storage). Based on the content of the processing) and the result of the detection process of the graphic 401 by the graphic detection unit 201, a determination process for determining the water discharge state according to the operation is performed (step S500).

  In the above-described flowchart, first, the process of detecting the figure 401 (graphic detection process) and then the process of detecting the operation (operation detection process) is described as an example. Processing for detecting an operation (operation detection processing) may be performed, and then processing for detecting the graphic 401 (graphic detection processing) may be performed.

  FIG. 5 is a flowchart illustrating an operation example of the water discharge control device 20A according to the second embodiment. Here, the flow of the “graphic position storage process” shown in step S300 will be described with reference to FIG.

  First, the coordinate extraction unit 203 determines whether or not the graphic 401 is detected in the image captured by the imaging device 10 based on the detection result output from the graphic detection unit 201 (step S301).

When determining that the figure 401 is detected in the image, the coordinate extraction unit 203 extracts the position coordinates (position SP) of the figure 401 (step S302).
Then, the coordinate extraction unit 203 stores the extracted position SP in the position information storage unit 206 (step S303).
On the other hand, when the coordinate extraction unit 203 determines in the process shown in step S301 that the graphic 401 is not detected in the image, the coordinate extraction unit 203 performs the process shown in step S400.

  FIG. 6 is a flowchart illustrating an operation example of the water discharge control device 20A according to the second embodiment. Here, the flow of the determination process shown in step S500 will be described with reference to FIG.

First, the target object detection unit 200 determines whether the target object 400 is detected from the image (step S501). When the operation is detected from the image, the coordinate extraction unit 202 extracts the position TP of the object (step S502). The coordinate extraction unit 202 outputs the extracted operation position TP to the coincidence detection unit 204.
Next, the graphic detection unit 201 determines whether or not the graphic 401 is detected from the image (step S503).

  When the figure 401 is detected from the image, the coordinate extraction unit 203 extracts the position coordinate (position SP) of the figure 401 and detects the coincidence of the extracted position coordinate (position SP) of the figure 401 via the selection unit 205. Output to the unit 204.

On the other hand, when the graphic 401 is not detected from the image in the processing shown in step S503, the selection unit 205 refers to the position information storage unit 206 and determines whether the position coordinates of the graphic 401 are stored (step S506). ).
When the position coordinates of the figure 401 are stored, the selection unit 205 outputs the position coordinates of the figure 401 stored in the position information storage unit 206 to the coincidence detection unit 204 (step S507).

  The coincidence detection unit 204 determines whether or not the position SP of the figure 401 matches the position of the operation position TP (step S504). Specifically, the coincidence detection unit 204 determines whether or not the position coordinates of the position SP of the graphic 401 are within a predetermined range from the position coordinates of the operation position TP. When the position SP of the figure 401 matches the position of the operation position TP, the coincidence detection unit 204 determines the water discharge state based on the content of the operation shown in the figure 401 and the operation performed on the figure 401. Is controlled (step S505). Then, the water discharge control device 20A returns to the process shown in step S100.

  On the other hand, when no operation is detected from the image in the process shown in step S501, when the position coordinate of the figure 401 is not stored in the process shown in step S506, and in the process shown in step S504, the position SP of the figure 401 and the position of the operation are stored. When the position of TP does not match, the water discharge control device 20A returns to the process shown in step S100.

  As described above, in the water discharge control device 20A of the second embodiment, the coincidence detection unit 204 detects the position SP of the graphic 401 by the selection unit 205 when the graphic detection unit 201 detects the graphic 401. The water discharge state is controlled by using the position SP of the graphic 401 stored in the storage unit 206 and stored in the positional information storage unit 206 when no graphic is detected by the graphic detection unit 201.

  When a person operates the figure 401, it is conceivable that the target object 400 is placed so as to overlap the figure 401. In this case, if the target object 400 exists between the figure 401 and the imaging apparatus 10, the figure 401 is obscured by the target object 400 when the direction of the figure 401 is viewed from the imaging apparatus 10. It is considered that a situation occurs in which all or part of the graphic 401 is not captured. In such a case, since all or part of the graphic 401 does not exist in the image, the graphic 401 may not be detected by the graphic detection unit 201, and it may be determined that there is no graphic 401 in the image. obtain.
