[Embodiment]
[Example of display control processing]
Hereinafter, as an example of the monitoring device, the monitoring device 100 included in the lighting system 1 will be described using an example. FIG. 1 is a diagram illustrating an example of a monitoring device 100 according to the embodiment. In the example shown in FIG. 1, the lighting system 1 includes a plurality of lighting devices 10 (shown as lighting devices 10a, 10b, and 10d in FIG. 1. , A plurality of RDM nodes 20 (shown as RDM nodes 20-1 to 20-n in FIG. 1; collectively referred to as “RDM nodes 20” when there is no need to distinguish each), a hub 30, a control console 40 The monitoring device 100 is included. Note that the types and number of lighting devices 10 and RDM nodes 20 included in the lighting system 1 can be arbitrarily changed.

  In the lighting system 1, the lighting device 10 is a lighting device capable of bidirectional communication with the RDM node 20 and the monitoring device 100 by a communication method in accordance with an RDM (Remote Device Management) standard that extends DMX. That is, the illumination device 10 according to the embodiment is an illumination device that complies with the RDM standard.

  In the present embodiment, description will be made along the RDM standard. However, a system capable of bidirectional communication (for example, ACN (Architecture) defined as an Ethernet (registered trademark) standard in which ESTA (Entertainment Services and Technology Association) is changed to DMX. for Control Networks) or sACN (streaming ACN)).

  The lighting device 10 includes a semiconductor light emitting element such as an LED (Light Emitting Diodes) and a motor mounted. By changing the brightness, range, color, angle, and the like in accordance with a control signal, the lighting device 10 includes: , Lighting production for studios and stages. The lighting device 10 is a facility installed in an arbitrary space such as a studio or a stage, and is installed in a baton that is a suspension device for suspending the lighting device. In the example of FIG. 1, it is shown that the lighting devices 10a, 10b, and 10d are installed in the baton L-1.

  The RDM node 20 is a distributor that distributes control information capable of bidirectional communication with the lighting device 10 and the monitoring device 100 by a communication method in accordance with the RDM standard that is an extension of DMX. Specifically, the RDM node 20 is connected to the hub 30 through a wired or wireless network such as Ethernet in a manner capable of bidirectional communication, and communicates with the monitoring device 100 and the like via the hub 30.

  Further, in the example of FIG. 1, the RDM node 20 is installed in the baton, like the lighting device 10. In the example of FIG. 1, the RDM node 20-1 is installed in the baton L-1, the RDM node 20-2 is installed in the baton L-2, and the RDM node 20-n is installed in the baton L-n. Is installed. Further, the RDM node 20 acquires information on the baton in which the RDM node 20 is installed and information on the lighting device 10 connected to the RDM node 20 and returns the information to the monitoring device 100. Note that the baton information may be stored in advance in the monitoring apparatus 100 if the RDM node is fixed.

  The RDM node 20 has a plurality of ports. The example of FIG. 1 indicates that the RDM node 20-1 has ports 20a to 20d. Each of the ports 20a to 20d is a port to which a port ID for identifying each port is assigned, and is, for example, a connection terminal (connector) for transmitting / receiving a signal to / from the lighting device 10 according to the RDM standard.

  Further, in the example of FIG. 1, an example in which the positions of the ports 20a to 20d in the baton L-1 are the positions P11 to P14 is shown. In the present embodiment, the positions of the respective ports 20a to 20d are indicated by conceptual symbols, but actually, for example, when the port 20a is viewed from the “specific direction” when the baton L-1 is viewed. The position, for example, “leftmost” is shown. In the case of the port 20b, the position when the baton L-1 is viewed from a specific direction, for example, “second from the left” is indicated.

  In addition, how to show the position of each port with respect to such a baton is only an example, and arbitrary notation may be used. For example, the position of each port may be indicated by coordinates relative to the baton. In addition, each baton has identification information (for example, an identification number or a name) that can identify the baton at a predetermined location, and such identification information can be visually recognized (for example, with respect to the baton). Front) corresponds to “specific direction”.

  Summarizing the above, in the example of FIG. 1, the lighting device 10a is connected to the port 20a that currently exists at the position P11 and is present at the position P12 in the RDM node 20-1 where the baton L-1 is installed. The lighting device 10b is connected to the port 20b, the lighting device 10 is not connected to the port 20c existing at the position P13, and the lighting device 10d is connected to the port 20d existing at the position P14.

  Here, the control process performed by the RDM node 20 will be described. The RDM node 20 sets a control address using an RDM function according to an instruction from a control console 40 described later for the lighting device 10 connected to each port (for example, the ports 20a to 20d). For example, when the RDM node 20 receives information on a control address newly assigned to the lighting device 10 installed in each port from the control console 40, the RDM node 20 sets a control address newly assigned to the lighting device 10 according to the information. Then, the RDM node 20 temporarily stores the newly assigned control address in association with the port ID of the port to which the lighting device 10 is connected.

  The RDM node 20 acquires information related to the lighting device 10 connected to the port according to an instruction from the monitoring device 100. For example, the RDM node 20 outputs a lighting device information read request from each of the ports 20a to 20d. When the RDM node 20 receives the lighting device information as a response from the lighting device 10, the RDM node 20 temporarily associates the port ID of the port that has received the lighting device information with the newly assigned control address. Remember.

  Further, when the RDM node 20 acquires the lighting device information, the RDM node 20 transmits identification information for identifying each device to the monitoring device 100 described later together with the acquired lighting device information, and the monitoring device 100 receives the information received from the RDM node. Remember. Specifically, the RDM node 20 associates the baton ID, the lighting device ID, the port ID, and the ID of the own device, that is, the node ID, and transmits them to the monitoring device 100 described later together with the lighting device information. This point will be described with reference to the example of FIG. In this embodiment, in order to simplify the explanation, it is assumed that the reference numerals assigned to the baton, the RDM node, the port, and the lighting device correspond to the identification information (ID) of each device.

  For example, it is assumed that the lighting device 10a is connected to the port 20a of the RDM node 20-1 installed in the baton L-1. In such a case, the RDM node 20-1 acquires the port ID “20a” and the lighting device ID “10a” from the port 20a according to an instruction from the monitoring apparatus 100. Then, the RDM node 20-1 transmits the baton ID “L-1”, the port ID “20a”, the lighting device ID “10a”, and the own device ID (node ID) “20-1” to the monitoring device 100. . The RDM node 20-1 also transmits lighting device information related to the lighting device 10a together with these IDs. Such lighting device information includes, for example, energization time, lighting time, information (for example, luminance) obtained by quantifying the current brightness, lighting color, power consumption, failure information, and the like. Further, the RDM node 20-1 performs the same processing for the ports 20b, 20c, and 20d. The same applies to the RDM node 20-2 and the RDM node 20-n.

  The hub 30 is connected to the control console 40 in a manner capable of bidirectional communication via a wired or wireless network such as Ethernet, and is a relay that relays communication between the control console 40 and each RDM node 20.

  Although not shown, the lighting system 1 includes a power supply device that supplies power to the lighting device 10. Such a power supply device has, for example, a voltage conversion function, a breaker, a detection function such as overload or electric leakage, and a UPS (Uninterruptible Power Supply) function.

  The control console 40 is a control device that can communicate control information having bidirectionality (for example, corresponding to the RDM standard) with the lighting device 10. When the control console 40 receives an operation command for the lighting device 10 from a user (for example, an operator who operates the control console 40), the control console 40 generates control information including a control address assigned to the lighting device 10, and passes through the hub 30. Control information is transmitted to the RDM node 20. In this case, the RDM node 20 converts the control information into a control signal (for example, a DMX signal) conforming to the RDM standard, and outputs the control signal to the lighting device 10 indicated by the control address. Thereby, control of the illuminating device 10 is performed. As described above, the lighting device 100 remotely controls each lighting device 10 using the control address included in the control information corresponding to the RDM standard.

  The monitoring device 100 monitors the installation status of the lighting device 10 with respect to the baton. For example, the monitoring device 100 receives the ID of each device (baton, port, lighting device, node) from the RDM node 20 as described above, because the lighting device 10 is compatible with the RDM standard. It is monitored which lighting device 10 is installed in the baton.

  Moreover, the connection of the lighting device 10 to the port of each RDM node 20 is manually performed by an operator. In order to carry out such a manual operation, a setting drawing in which which lighting device 10 is set at which position of which baton is set and the drawing is raised is prepared in advance. Therefore, the worker connects the lighting device 10 many times with reference to this preparation drawing so as not to install the lighting device at an incorrect position. In such a case, since it is necessary for the worker to check the prepared drawing many times, it takes time, and as a result, the work efficiency is lowered.

  In addition, since an enormous number of lighting devices 10 are installed, even if they are installed at positions that are different from the preparation drawings, they may not be noticed. In such a situation, for example, suppose that the baton where the lighting device 10 has been installed is raised, and after setting the stage set on the stage, the user notices that the installation position is incorrect. In such a case, the stage set is moved or dismantled and the baton is lowered to correct the installation position, or the installation position is corrected by taking a risk to climb a high stepladder, resulting in a significant reduction in work efficiency. .

  Therefore, the monitoring apparatus 100 according to the embodiment compares information related to the lighting device 10 based on a captured image obtained by capturing a baton in which the lighting device 10 is installed, and information related to the preset lighting device 10. Then, the monitoring apparatus 100 displays the compared result on the predetermined display device. Below, the display control process by such a monitoring apparatus 100 is demonstrated concretely.

  First, the worker takes an image of a work baton to which the lighting device 10 is to be installed using a terminal device equipped with a camera function (step S1). In the following, the installation of the lighting device 10 in the baton and the connection of the lighting device 10 to the port of the RDM node 20 may be treated as being synonymous.

  The terminal device equipped with the camera function is assumed to be the wearable glass shown in FIG. However, such a terminal device is not limited to wearable glasses, and any terminal device having a camera function, a display function, and a communication function using Ethernet may be used. For example, the terminal device may be a smartphone, a tablet terminal, a notebook PC (Personal Computer), a desktop PC, a mobile phone, a PDA (Personal Digital Assistant), or the like.

  And the example of FIG. 1 shows that the worker has photographed the entire baton L-1 using the wearable glass GL so that all the lighting devices 10a, 10b, and 10d installed in the baton L-1 can enter. Show. For example, the worker performs the above photographing while wearing the wearable glass GL, that is, while actually viewing the baton L-1 through the wearable glass GL.

  FIG. 1 shows an example in which the image captured in this way is a captured image G1. Here, the point at the time of imaging | photography is demonstrated. One is to shoot so that the entire baton to be worked and all of the lighting devices 10 installed in the baton can be accommodated in the captured image. The other is that each baton may be preliminarily described with identification information (for example, name, symbol, QR code (registered trademark), etc.) that can identify the baton at a predetermined location. In this case, the worker performs shooting from a direction in which the identification information fits in the captured image. Such a direction is, for example, a front direction with respect to the baton to be worked. Although not shown, in the example of FIG. 1, it is assumed that the worker has taken a picture so that the identification character “L-1” written on the surface of the baton L-1 enters.

  Next, the wearable glass GL transmits the captured image G1 captured according to the operation of the worker to the monitoring device 100 (step S2). When the monitoring device 100 receives the captured image G1 from the wearable glass GL, the monitoring device 100 performs image analysis of the captured image G1 (step S3). For example, the monitoring device 100 performs image analysis on the captured image G1, thereby identifying the identification information of the baton L-1 as information on the lighting device 10 and the position of the lighting device 10 in the baton L-1 being captured. Determine if is installed. Specifically, the monitoring device 100 analyzes the captured image G1 to identify baton identification information and identify the installation position of the lighting device 10 in the baton. At this time, since the monitoring device 100 can also grasp the position of the port in the baton L-1, in the RDM node 20-1, the port at which the lighting device 10 is connected may be specified. That is, the monitoring apparatus 100 may recognize the lighting device 10 installed near the port as a lighting device connected to the port.

  In the example of FIG. 1, the monitoring device 100 specifies, by image analysis, that the baton photographed in step S1 is the baton L-1, and the lighting device 10 is connected to the ports at the positions P11, P12, and P14. Identify that is connected. For example, the monitoring device 100 may specify the position P11 as “leftmost”, the position P12 as “left 2 (second from the right)”, and the position P14 as “rightmost”. The monitoring apparatus 100 may specify the coordinate direction such as “X1” as the position P11, “X2” as the position 12, and “X4” as the position P14.

  In addition, the monitoring apparatus 100 can also specify the type of the lighting device 10 installed in the baton, unique identification information, and the installation direction as information on the lighting device 10 by image analysis. For example, the monitoring apparatus 100 analyzes the appearance of the lighting device 10 with respect to the type and installation direction of the lighting device such as whether the lighting device 10 installed in the baton L-1 is a spotlight, a horizont light, or a flood light. Can be specified.

  In addition, by capturing identification information such as a QR code installed in the lighting device 10, the monitoring apparatus 100 may acquire the lighting device ID such as identification information unique to the lighting device 10 or an arbitrarily set address. . In this case, the monitoring apparatus 100 can specify not only the type and installation direction of the lighting device 10 but also the lighting fixtures 10 one by one.

  Next, the monitoring device 100 compares the positional information related to the lighting device 10 that is specified by the image analysis and the information related to the lighting device 10 set in advance (step S4). Here, the monitoring apparatus 100 includes a device information storage unit 120. In the device information storage unit 120, a preparation drawing, which is a drawing in which which lighting device 10 is to be installed at which position of which baton, is stored in a state of being digitized and symbolized. In some cases, the numerically and symbolized preparation chart is referred to as “preparation chart data”.

  In the device information storage unit 120 illustrated in FIG. 1, an RDM node “20-1” is installed in the baton “L-1” in the preparation diagram, and the position of the port in the baton “L-1” is the position P11 and the position P12. , Position P13, position P14, and the fact that the type of lighting device 10 to be installed is a spotlight indicates that it is described in advance in the preparation drawing. Furthermore, the device information storage unit 120 may store a lighting device ID that is identification information of each lighting device 10 as preparation diagram data.

  Therefore, the monitoring apparatus 100 is position information specified by image analysis as information related to the lighting device 10 based on the captured image G1, and is information regarding a position of a port to which the lighting device 10 is connected and information regarding the lighting device 10 set in advance. The position information of the port in the baton L-1 derived from the preparation diagram is compared. And the monitoring apparatus 100 specifies the location which does not correspond by such comparison.

  In the example of FIG. 1, the monitoring apparatus 100 specifies that a match at the position P13 cannot be obtained by the comparison process. Specifically, the monitoring device 100 is actually designated to connect the lighting device 10 (spotlight) to the port at the position P13 in the baton L-1 on the “preparation diagram data” side, but actually Specifies that the lighting device 10 (spotlight) is not connected to the port at position P13.

  Thus, the presence of a point where no match is obtained in the comparison processing indicates that there is an error in the connection of the lighting device 10 or the lighting device 10 is not connected. Therefore, the monitoring apparatus 100 performs display control so that the worker can confirm the correct installation mode of the lighting device 10 based on the preparation drawing data via the wearable glass GL.

  Specifically, the monitoring apparatus 100 recognizes that the lighting device 10 is connected to the port at the position P13 by specifying that the lighting device 10 (spotlight) is not connected to the port at the position P13. An animation image G2 is generated. And the monitoring apparatus 100 transmits the produced | generated animation image G2 to the wearable glass GL as a comparison result (step S5). As a result, the monitoring apparatus 100 displays the animation image G2 in such a manner as to instruct to connect the spotlight to the position P13 in the actual baton L-1 that is currently visually recognized by the worker through the wearable glass GL. It is displayed (step S6).

  As a result, the worker should confirm how to install the lighting device 10 for the baton to be worked on without checking the preparation drawing many times, or the position of the already installed lighting device 10 is incorrect. It will be possible to confirm at a glance whether there is any. For this reason, since the monitoring apparatus 100 concerning embodiment can enable a worker to perform the installation operation | work of the illuminating device 10 easily and correctly, it raises the work efficiency concerning installation of the illuminating device 10. Can do.

  In the example of FIG. 1, the monitoring apparatus 100 has shown an example in which the lighting device 10 that is an error target or a connection target is displayed as an animation on the baton and the lighting device 10 that the worker actually looks at. The animation display is not limited to this. For example, the monitoring apparatus 100 may display an animation of all of the work baton and the lighting device 10.

The “port ID” indicates identification information for identifying a port included in the node identified by the corresponding “baton ID”.

  The “port position” indicates the installation position of the port identified by the corresponding “port ID” and the baton identified by the corresponding “baton ID”. In addition, such an installation position can be understood as the installation position of the lighting device 10 with respect to the baton. As described with reference to FIG. 1, the “port position” is indicated by, for example, a position direction and coordinates based on left and right. The “lighting device ID” is identification information indicating the lighting device 10 connected to the port identified by the corresponding “port ID”.

For example, the comparison unit 133 compares the position information that is specified by the analysis unit 132 and that is related to the lighting device 10 with information that is set in advance about the lighting device 10. The information related to the lighting device 10 set in advance is, for example, preparation diagram data stored in the device information storage unit 120.

  In addition, when the type of the lighting device 10 is specified by the analysis unit 132, the comparison unit 133 compares the type of the specified lighting device 10 with the type of the lighting device 10 set in advance in the preparation drawing data. To do. In addition, the installation direction of the lighting device 10 may be set in advance in the preparation drawing data. In such a case, the comparison unit 133 compares the installation direction of the illumination device 10 specified by the analysis unit 132 with the installation direction of the illumination device 10 in the preparation drawing data.

  Then, the comparison unit 133 identifies a mismatch between the information related to the illumination device 10 based on the captured image and the information related to the preset illumination device 10 through the comparison process as described above. For example, the comparison unit 133 specifies position information that is the position information specified by the analysis unit 132 and does not match the position information of the lighting device 10 in the preparation drawing data among the position information related to the lighting device 10. Similarly, the comparison unit 133 identifies a mismatch with respect to the preparation drawing data for the type and installation direction of the lighting device 10.

(About the display control unit 134)
As a comparison result, the display control unit 134 displays content indicating that the information about the lighting device 10 set in advance does not match. Specifically, the display control unit 134 causes the comparison result obtained by the comparison by the comparison unit 133 to be displayed on the terminal device of the captured image transmission source. More specifically, the display control unit 134 generates an animation image as content based on the comparison result obtained by the comparison by the comparison unit 133. For example, the display control unit 134 generates an animation image that allows the operator to recognize the comparison result by the comparison unit 133 via the terminal device.

  As an example, the display control unit 134 causes the baton and the lighting device 10 that the worker is actually viewing through the terminal device to recognize the lighting device 10 that is incorrectly installed, Alternatively, an animation image is generated that instructs to connect the target lighting device 10 to a port determined in the preparation drawing data.

  Then, the display control unit 134 transmits, for example, the generated animation image to the terminal device so that the generated animation image is superimposed and displayed on the baton and the lighting device 10 that the worker actually looks through the terminal device. .

  In addition, when the lighting device 10 compliant with the RDM standard is installed in the baton, the display control unit 134 uses the reception of the various identification information by the receiving unit 131, so that the display control unit 134 The installation position may be displayed. Specifically, the display control unit 134 displays detailed information such as which lighting device 10 is connected to which port together with the animation image using, for example, identification information.

  Now, an example of display control processing by the monitoring apparatus 100 will be described below with reference to FIG. FIG. 4 is a diagram illustrating an example of the display control process performed by the monitoring apparatus 100 according to the embodiment. Note that the description with reference to FIG. 4 makes FIG. 1 more detailed, and therefore, the contents already described in FIG. 1 are omitted.

  First, it is assumed that the wearable glass GL has photographed the entire baton L-1 so that all the lighting devices 10a, 10b, and 10d installed in the baton L-1 enter according to the operation of the worker. The image captured in this way is a captured image G1. The wearable glass GL transmits the captured image G1 to the monitoring device 100.

  When the reception unit 131 receives the captured image G1, the analysis unit 132 of the monitoring apparatus 100 performs image analysis on the received captured image G1. For example, the analysis unit 132 obtains an analysis result R1 as shown in FIG. 4 by image analysis. Specifically, the analysis unit 132 specifies that a spotlight is installed as the lighting device 10 at each of the ports at the position P11, the position P12, and the position P14 in the baton L-1. For example, when identification information (for example, a QR code) of the lighting device 10 is attached to each lighting device 10, the analysis unit 132 also includes the lighting device ID specified from the QR code by image analysis. It can be included in the analysis result R1.

  Here, it is assumed that a spotlight corresponding to the RDM standard is installed in the baton L-1 in advance. In addition, it is assumed that the lighting device 10 currently connected to the ports at the positions P11, P12, and P14 is also a spotlight that complies with the RDM standard. As described above, when the target lighting device 10 conforms to the RDM standard, the monitoring apparatus 100 not only displays an animation image as described above, but also includes more detailed information regarding the lighting device 10. Can be displayed. That is, the display control unit 134 displays detailed information regarding the lighting device 10 to be installed on the baton based on information (for example, various IDs and setting modes) received from the lighting device 10 photographed with the baton.

  For example, the comparison unit 133 adds more detailed information to the analysis result R1 obtained by the analysis unit 132 by cooperating with the RDM as a pre-stage for performing the comparison process. For example, the comparison unit 133 associates “port ID” and “lighting device ID” with the analysis result R1 as illustrated in FIG. That is, the comparison unit 133 associates the “port ID” and the “lighting device ID” received by the receiving unit 131 when the lighting device 10 is RDM standard compliant based on the device information storage unit 120 illustrated in FIG. .

  For example, the comparison unit 133 refers to the device information storage unit 120 when the reception unit 131 receives information indicating that the lighting device 10b is connected to the port 20a, and the port 20a is a port corresponding to the position P11. Identify that there is. Then, the comparison unit 133 adds these pieces of information to the analysis result R1 so that the port ID “20a”, the port position “P11”, and the illumination device ID “10b” correspond to each other. As described above, the detailed information added to the analysis result R1 by the comparison unit 133 is the analysis result R2 shown in FIG.

  Then, the comparison unit 133 compares the analysis result R2 with the preparation drawing data stored in the device information storage unit 120 to identify a mismatch between the two.

  In the preparation drawing data, it is preset that the lighting device 10a is connected to the port 20a at the position P11. In the preparation drawing data, it is set in advance that the lighting device 10b is connected to the port 20b at the position P12. However, according to the analysis result R2, the lighting device 10b is currently connected to the port 20a, and the lighting device 10a is connected to the port 20b. Therefore, the comparison unit 133 specifies that the connection between the lighting devices 10a and 10b is incorrect.

  In the preparation drawing data, it is preset that the lighting device 10c is connected to the port 20c at the position P13. However, according to the analysis result R2, there is currently no connection to the port 20c. Therefore, the comparison unit 133 specifies that the lighting device 10c is not connected to the port 20c.

  And the display control part 134 produces | generates an animation image based on the comparison result obtained by the comparison part 133 as mentioned above, and displays the produced | generated animation image on the wearable glass GL. For example, the display control unit 134 displays information related to the lighting device 10 connected to each port. Specifically, for example, the display control unit 134 is correct to connect to the lighting devices 10a and 10b that are erroneously connected, for example, so as to know which specific lighting device 10 is connected to which port. Information about the lighting device 10 (for example, a lighting device ID) is displayed. Further, a comment or a picture indicating that the connection is incorrect may be displayed.

  Further, as shown in FIG. 4, the display control unit 134 may display the device type, mode, illumination angle, and the like. The device type, mode, and illumination angle are information set in advance in the preparation drawing.

  The display control unit 134 also recognizes that the lighting device 10c is connected to the port 20c when the comparison unit 133 specifies that the lighting device 10c is not connected to the port 20c at the position P13. Is generated. Then, the display control unit 134 displays the generated animation image G2 on the wearable glass GL.

  Thereby, even if the detailed setting is made such that the lighting device 10 corresponding to the specific ID is connected to the specific port in the preparation drawing, the worker confirms the preparation drawing many times. Without any problem, it is possible to easily recognize such a setting through the wearable glass while performing the work. Therefore, the monitoring apparatus 100 can improve work efficiency.

  FIG. 4 shows an example in which no animation is displayed for the lighting device 10 that is correctly installed with respect to the baton L-1, specifically, the lighting device 10 connected to the port 20d. However, the display control unit 134 displays, for example, the device type, the lighting device ID, the mode, and the angle so that the worker can reconfirm the installation mode even when the display control unit 134 is correctly installed in this way. May be.

  In the example of FIG. 4, in the analysis result R1, there is no display for the lighting device IDs installed at the respective port positions, but the lighting device IDs of the lighting devices 10 installed at the respective port positions by image analysis are combined. You may make it match | combine. In this case, in the process of obtaining the analysis result R2, the monitoring apparatus 100 does not match the correspondence between the port position acquired by RDM and the lighting device ID and the correspondence between the port position and the lighting device ID in the analysis result R1. It can be identified. That is, when the device information storage unit 120 stores the illumination device ID corresponding to each illumination device 10, the monitoring device 100 has the port ID and the illumination device ID properly connected as shown in the drawing. It is possible to specify that the installation position of the device 10 is wrong and to display that fact.

[Display control processing flow]
Next, the procedure of the process by the illumination system 1 according to the embodiment will be described with reference to FIG. FIG. 5 is a sequence diagram illustrating a display control processing procedure by the illumination system 1 including the monitoring device 100 according to the embodiment.

  First, the receiving unit 131 of the monitoring device 100 determines whether a captured image is received from a terminal device (a display terminal such as a wearable glass GL) (step S101). If it is determined that the captured image has been received (step S101; Yes), the analysis unit 132 performs image analysis on the received captured image (step S102). On the other hand, if the receiving unit 131 determines that a captured image has not been received (step S101; No), the receiving unit 131 waits until it is received.

  Next, when the analysis result is obtained by image analysis, the comparison unit 133 is information transmitted from the RDM node 20 included in the captured image and is connected to a port included in the RDM node 20 It is determined whether information related to 10 has been received (step S103). For example, when the lighting device 10 conforms to the RDM standard, the comparison unit 133 receives the baton ID, node ID, port ID, and lighting device ID transmitted from the RDM node 20 included in the captured image by the receiving unit 131. It is determined whether or not it has been received.

  When the baton ID, the node ID, the port ID, and the lighting device ID are received as information related to the lighting device 10 (Step S103; Yes), the comparison unit 133 associates the received identification information with the analysis result (Step S103). S104). Next, the comparison unit 133 compares the analysis result after the process of step S104 with the preparation diagram data stored in the device information storage unit 120 (step S105).

  Then, the display control unit 134 generates an animation image based on the comparison result obtained by the comparison unit 133 (Step S106). Then, the display control unit 134 transmits the generated animation image so as to be displayed by the terminal device that is the captured image transmission source (step S107).

  Note that the comparison unit 133 performs analysis when the baton ID, the node ID, the port ID, and the lighting device ID are not received as information about the lighting device 10 (step S103; No), that is, when the lighting device 10 does not comply with the RDM standard. The analysis result obtained by the unit 132 is compared with the preparation drawing data stored in the device information storage unit 120 (step S105).

[Variations of image analysis and comparison processing]
In the example of FIG. 1, an example is shown in which the analysis unit 132 specifies to which port the lighting apparatus 10 is connected by image analysis. That is, the example in which the analysis unit 132 specifies the installation position of the lighting device 10 in the baton by using the position of the port by image analysis is shown. However, the analysis unit 132 specifies the connection mode of the cable in which the lighting device 10 and the port are connected by image analysis, and the comparison unit 132 compares the specified connection mode with the preparation drawing data to connect the cable. May be detected. That is, the comparison unit 132 may determine whether or not there is an error in the cable connection between the lighting device 10 and the port.

  In such a case, in the preparation drawing data, it is designated in advance which port the lighting device 10 in which installation position is connected to. For example, using the example of FIG. 1, in the preparation diagram data, the lighting device 10 at the position P11 is connected to the port 20a that is the port corresponding to the position P11, and the lighting device 10 at the position P12 is associated with the position P12. Assume that it is designated in advance to connect to the port 20b which is the port to be connected.

  Here, the analysis unit 132 analyzes the captured image to connect the lighting device 10 at the position P11 to the port (port 20b) corresponding to the position P12, and the lighting device 10 at the position P12 corresponds to the position P11. It is assumed that the connection to the port (port 20a) is specified. In other words, it is assumed that the analysis unit 132 specifies that the cables intersect.

  In such a case, the comparison unit 132 compares the analysis result specified by the analysis unit 132 as described above with the prepared drawing data, and the lighting device 10 at the position P11 is assigned to the port (port 20a) corresponding to the position P11. It is determined that the lighting device 10 at the position 12 is connected to the port (port 20a) corresponding to the position P11, and the cable connection is incorrect.

  Further, the comparison unit 132 determines that the lighting device 10 at the position P12 has to be connected to the port (port 20b) corresponding to the position P12, and the port (port) at which the lighting device 10 at the position P11 corresponds to the position P12. 20b) and it is determined that the cable connection is incorrect. As a result, the display control unit 134 generates an animation image instructing correct connection because the cable connection is incorrect, and displays the animation image on the wearable glass GL.

  If there is an error in the cable connection as described above, an error also occurs in the DMX address that should be originally assigned to each lighting device 10, but the monitoring apparatus 100 according to the embodiment prevents such an error from occurring. can do.

[Variations of display control processing]
In the said embodiment, as shown in FIG. 3, the example in which it was decided beforehand to connect the illuminating device 10 to all the ports in each baton was shown. However, in the baton, there is a case where a rule is set such that the lighting device 10 is not connected to a specific port. Such a rule is also set in advance in the preparation drawing.

  In such a case, if the comparison unit 133 is information related to the lighting device based on the photographed image, is the lighting device 10 installed for the baton according to a predetermined rule indicated in the preparation diagram data by comparison with the preparation diagram data? Determine whether or not. When it is determined that the display control unit 134 is not installed according to a predetermined rule, the display control unit 134 displays an animation of a correct installation mode corresponding to the predetermined rule.

  This point will be described with reference to FIG. In the captured image G1 captured by the wearable glass GL, the illumination devices 10 are installed at the positions P11, P12, and P14 in the baton L-1. Here, although not shown in the drawing, it is assumed that it is predetermined as a rule that the lighting device 10 is not installed at the position P14 in the preparation diagram data.

  In such a case, the comparison unit 133 identifies that the illumination device 10 is not installed according to this rule by comparing the analysis result obtained by analyzing the captured image G1 with the prepared drawing data. Specifically, the comparison unit 133 specifies that the lighting device 10 is installed at the position P14 that should not be installed, and outputs such a specification result to the display control unit 134.

  The display control unit 134 receives the output from the comparison unit 133 and generates an animation image. For example, the display control unit 134 generates warning information as an animation image for warning that the connection to the position P14 is prohibited. And the display control part 134 transmits to the wearable glass GL so that the produced animation image may be displayed.

However, the camera may be independent from the terminal body, such that the camera device is externally connected to the notebook computer or tablet device. For example, the camera device may be a surveillance camera installed in a studio or the like, or a fixed camera installed to perform the various processes described above.

  Moreover, in the said embodiment, the analysis part 132 showed the example which specifies a baton with the identification information described in the baton. However, the analysis unit 132 may specify a baton based on the shape of the baton. In addition, the display control unit 134 can employ any other method for displaying the comparison result instead of displaying the comparison result as an animation image. The lighting device 10 is not limited to the RDM standard as long as bidirectional communication is possible.

  In the monitoring device 100 described above, a computer having a CPU (Central Processing Unit), a RAM (Random Access Memory), an EEPROM (Electrically Erasable Programmable Read-Only Memory), a flash memory, and the like is registered in a predetermined recording medium. It may be realized by reading the control program and executing the read control program.
