Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stage mechanism monitoring device for monitoring the vertical movement of a curtain provided on a stage.

[0002]

2. Description of the Related Art FIG. 3 is an external view showing the entire stage. Generally, various stage mechanisms are provided on the stage. As these stage mechanisms, for example, a rotating stage 2 is provided for the main stage 1, and when a predetermined scene is reached, the rotating stage 2 is controlled to move to the main stage 1 side, and the scene ends. Then, there is one that controls the movement so as to move to the original position again. In this case, a stage mechanism for controlling the rotation of the orbiting stage 2 is also provided.

Further, as another stage mechanism, a curtain 3 is hung from above the stage 1, and the curtain 3 is controlled to move up, down, and stop. Furthermore, on each side of the stage 1, each sleeve 4 is hung by each baton 5,
These batons 5 are connected to each counterweight 6 via each fishing line. These sleeve screens 4 are configured to raise, lower, and stop the stage space by raising and lowering each counterweight 6 by driving a motor (not shown). Further, as the stage mechanism, although not shown, drive control of the stage, lighting control of lighting, control of its irradiation direction, and the like are provided.

By the way, the operating conditions of these stage mechanisms are determined for each scene of the play, for example, the destination position for moving the curtain 3 up and down, the moving speed thereof, etc., and the operation is controlled according to the destination position, the moving speed, etc. ing. And
The operating state of these stages is monitored in a monitoring room provided on the sleeves of the stage.

More specifically, for example, the ascending / descending position of the curtain 3 is detected by a position detector (PC), and the detected position value is transmitted to the monitoring room. In this monitoring room, the detected position value is displayed numerically to inform the operator of the vertical position of the curtain 3. It should be noted that this is not limited to the raising / lowering position of the curtain 3,
Various detectors for detecting the rotating position of the rotating stage 2 and the ascending / descending position of each sleeve 4 are provided, and these detected values are sent to the monitoring room and displayed as numerical values.

Further, since there are cases where the state of the stage 1 is hidden from the surveillance room by the curtain 3, the sleeve 4, etc., and cannot be monitored, a surveillance camera for picking up these hidden stage mechanisms is provided.
Then, the captured image is displayed in the monitoring room.

By the way, the stage mechanism which can be visually observed directly from the monitoring room can monitor only a part of each stage mechanism. This is because the surveillance mechanism may be surrounded by walls and equipment, hidden by the shadows of other stage mechanisms, or the lighting may be dimmed and become invisible during the screening. For this reason, for each stage mechanism that is a blind spot from the operator for such a reason, the state is monitored by the numerical value displayed in the monitoring room.

However, the stage mechanism is operated to raise and lower the curtain 3 and the like when each scene changes during the progress of the drama, at which time the lighting is turned off and it is difficult to monitor. It is generally done. That is,
If the lighting is on, even if the stage mechanism allows direct visual observation, the lighting is turned off and direct observation cannot be performed.

For this reason, the operator must monitor the operating state of each stage mechanism in the absence of lighting. Therefore, the operator must be familiar with the operation of each stage mechanism and, in addition, must be familiar with the progress of the drama. I have to.

Although it is conceivable to increase the number of surveillance cameras installed in order to eliminate a blind spot with respect to the stage mechanism, this causes a problem in that the installation place is limited and the cost is reduced.

[0011]

As described above, it is necessary to monitor the operating state of each stage mechanism in the absence of illumination. Therefore, the operator is well aware of the operation of each stage mechanism, and the progress of the drama. Familiarity with is required. or,
Increasing the number of surveillance cameras installed poses problems in terms of cost and installation space.

Therefore, the present invention is a stage mechanism monitor capable of reliably and easily monitoring the state of the stage space even if there is no illumination and it is not possible to directly monitor the operating state of each stage mechanism in the shadow of another stage mechanism. The purpose is to provide a device.

Further, the stage mechanism control device 17 has a function of passing the ascending / descending position S from the position detector 16 to the operation panel 18.

The three-dimensional image display device 30 has a function of receiving the ascending / descending position S from the stage mechanism control device 17 and displaying the state of the curtain 11 at the ascending / descending position S as a three-dimensional image. It is composed of a unit 31 and a CRT display 32.

Specifically, the three-dimensional image processing unit 31 is provided with a stage design data memory 33, and the memory 33 stores the stage design data of the entire stage shown in FIG.
This stage design data includes, for example, the dimensions of the stage 1, the diameter of the orbiting stage 2, the height of the ceiling, the length of the curtain 3, the width and length of each sleeve 4, the arrangement positions of the curtain 3 and the sleeve 4, All the data regarding the stage design such as the ascending / descending ranges of the curtain 3 and the sleeve curtains 4, the arrangement positions of the lights, and the illuminance thereof are stored.

Further, the three-dimensional image processing unit 31 is provided with a viewpoint changing unit 34, and the viewpoint changing unit 34 is used to instruct and set the viewpoint direction of the stage 1 displayed on the CRT display 32. This viewpoint direction is, for example, a direction viewed from the audience seats with respect to the stage 1, a direction viewed from the sleeve side of the stage 1, a direction viewed from the ceiling side, etc., and the viewpoint instruction is arbitrarily keyed by the operator. Has become.

Further, the viewpoint changing unit 34 has a function of presetting a plurality of viewpoint directions, and selecting and setting one of the viewpoint directions by the operator, and each viewpoint in a preset order. It has a function of changing the direction and a function of changing the distance of the viewpoint to the stage 1.

The three-dimensional graphic simulation unit 35 receives the ascending / descending position S from the stage mechanism control device 17, and based on the ascending / descending position S and the stage design data stored in the stage design data memory 33, the three-dimensional graphic simulating unit 35 is provided. Graphic processing is executed, and this processing shows the appearance of the stage space.
It has a function of creating a three-dimensional image and displaying it on the CRT display 32.

Further, the three-dimensional graphic simulation unit 35 has a function of creating a three-dimensional image of the state of the stage space viewed from the viewpoint direction set and designated by the viewpoint changing unit 34.

The three-dimensional graphic simulation unit 35 can arbitrarily adjust the brightness of the three-dimensional image created by the three-dimensional graphic processing regardless of the illuminance of the illumination provided on the stage. It has a function. Next, the operation of the apparatus configured as described above will be described.

(1) First, in the initial state, the curtain 11 is at the lower limit position. In this state, the operation switch 20 for stopping the operation panel 18 is operated, and the position detector 16 moves the curtain 11
The ascending / descending position S of is output as the lower limit value "0". As a result, the numerical value “0” is displayed on the display 22 of the operation panel 18.

On the other hand, the three-dimensional graphic simulation unit 35 receives the ascending / descending position S of the lower limit value "0", executes the three-dimensional graphic processing based on the ascending / descending position S and the stage design data, and the curtain 11 makes the lower limit value. Create a three-dimensional image showing the appearance of the stage space down to. Then, this three-dimensional image is displayed on the CRT display 32.

(2) In this initial state, when the operator operates the raising operation switch 19, a raising operation request F is sent from the operation panel 18 to the stage mechanism control device 17. In response to this operation request F, the stage mechanism control device 17
Drives the motor 15 in a rotating direction to raise the curtain 11. As a result, the rotation of the motor 15 is transmitted to the baton 12, and the curtain 11 rises.

At this time, the position detector 16 detects the rising position of the curtain 11 and outputs the ascending / descending position S thereof. And
The stage mechanism control device 17 receives the ascending / descending position S from the position detector 16 and feedback-controls the position of the curtain 11. After that, when a stop operation request F is input from the operation panel 18, the motor 15 is stopped. , Set the curtain 11.

Along with this, the ascending / descending position S output from the position detector 16 is sent to the operation panel 18, and the ascending / descending position S of the curtain 11 is numerically displayed on the display 22 of the operation panel 18.

On the other hand, the ascending / descending position S output from the position detector 16 is also sent to the three-dimensional graphic simulation unit 35. The three-dimensional graphic simulation unit 35 receives the ascending / descending positions S that are sequentially raised, executes three-dimensional graphic processing based on the ascending / descending positions S and the stage design data, and the curtain 11 sequentially rises in three states. Create a 3D image. As a result, on the CRT display 32, the appearance of the stage space in which the curtain 11 sequentially rises is 3
It is displayed as a three-dimensional graphic image. In this case, if the input of the ascending / descending position S of the curtain 11 and the update cycle of the display screen in the three-dimensional graphic simulation unit 35 are made sufficiently small, the raised state of the curtain 11 can be immediately displayed as a three-dimensional graphic image.

Therefore, the operator can immediately monitor the actual rising state of the curtain 11 by the three-dimensional graphic simulation image of the curtain 11 displayed on the CRT display 32.

The curtain 11 is not limited to the raised state, and the curtain 11
The descending state and the stopped state are also displayed on the CRT display 32 as a three-dimensional graphic simulation image. Therefore, these states can also be monitored by the operator.

(3) On the other hand, when the direction of the viewpoint and the distance of the viewpoint to the stage 1 are input as the viewpoint instruction by the key operation of the operator, the viewpoint changing unit 34 changes the viewpoint instruction to 3
It is passed to the dimensional graphic simulation section 35.

Upon receiving this viewpoint instruction, the three-dimensional graphic simulation unit 35 executes coordinate conversion, light irradiation direction conversion, etc. when executing three-dimensional graphic processing based on the ascending / descending position S and stage design data. Then, a three-dimensional image of the state of the stage space in which the curtain 11 gradually rises as viewed from the designated viewpoint direction and its distance is created. Therefore, the CRT display 32 displays the three-dimensional graphic simulation image for the curtain 11 in the designated viewpoint direction and distance.
Is projected on.

The viewpoint direction can be freely changed to a direction desired by the operator, such as the direction seen from the audience seats with respect to the stage 1, the direction seen from the sleeve side of the stage 1, the direction seen from the ceiling side as described above. To be Further, the viewpoint position may be set to be slightly shifted, and in this case, the viewpoint position may be sequentially shifted to the viewpoint position where it is easy to monitor the rising state of the curtain 11.

Thus, in the above-described embodiment, the curtain 1
The up and down position S of No. 1 is detected, and based on the detected up and down position S and the stage design data, a three-dimensional image of the stage space showing the up and down position S of the curtain 11 is created and displayed. Therefore, even if the lighting is turned off and it is not possible to directly monitor the operating state of each stage mechanism due to the shadow of other stage mechanisms, the up-and-down state of the curtain 11 can be reliably and easily monitored by the three-dimensional graphic simulation image. it can. Since the three-dimensional graphic simulation image is displayed as the entire stage, it is possible to monitor the ascending / descending position of the curtain 11 and the relationship with other stage devices in the entire stage.

Further, with such a device, since the stage mechanism can be directly monitored without being visually observed, the operating panel 18 and the three-dimensional image display device 30 are not limited to being installed on the sleeve side of the stage 1. It can be installed in a free place, such as a place where you cannot see Stage 1 directly.

Furthermore, since the viewpoint direction can be changed, the operation of the stage mechanism can be monitored from a direction that is easy for the operator to monitor. For example, even if the stage mechanism is hidden behind another stage mechanism, the stage mechanism can be changed by changing the viewpoint direction. It is also possible to monitor the operating state of, and also the interference of each stage mechanism and the positional relationship with the performer. The present invention is not limited to the above-mentioned embodiment, and may be modified within the scope of the invention.

For example, although the case where the present invention is applied to the curtain 11 has been described in the above-mentioned embodiment, in an actual medium-scale or larger stage, there are several tens of objects called hangings such as curtains and sleeves, and close-up stages. There are usually several to dozens of so-called floor objects.

Therefore, normally, all of these stage mechanisms are simultaneously displayed on the CRT display 32 as a three-dimensional graphic simulation image. This is possible because the stage design data memory 33 stores all stage design data for the entire stage.

As a result, even if each stage mechanism is arranged in a complicated manner, it is possible to simultaneously monitor the operating states of these stage mechanisms when moving for each scene change, and to monitor the operation of these stage mechanisms. It can be done smoothly.

[0045]

As described above in detail, according to the present invention, even if there is no illumination and it is not possible to directly monitor the operating state of each stage mechanism in the shadow of another stage mechanism, the stage can be performed reliably and easily. It is possible to provide a stage mechanism monitoring device capable of monitoring the state of the space.
