Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a planetarium projection device and a program for an astronomical simulator capable of producing simulated spaceflight and a unique motion of an astronomical object. In this specification, a planetarium refers to a facility that mainly projects an image of a starry field on a screen.
[0002]
[Prior art]
In recent years, some planetarium projectors and astronomical simulators that can project electronic images can produce stellar intrinsic motion and pseudo-space flight. The intrinsic motion of a star is a phenomenon in which individual stars move in space over a long period of time, and their apparent positions as viewed from the Earth change individually. In addition, the pseudo-space flight is a simulation function of, for example, escaping the earth and projecting a starfield seen in outer space tens of thousands of light years.
[0003]
Some of the planetarium projection devices or astronomical simulator software for personal computers that can produce the above-mentioned stellar intrinsic motion and pseudo-space flight are commercially available. However, since a document related to the present invention could not be found as a document, the prior art document information is not described in this specification.
[0004]
[Problems to be solved by the invention]
However, the above-mentioned conventional planetarium projector has the following problems. In other words, in the production of the intrinsic motion of a star, it simulates the way the position of the star changes over time of more than tens of thousands of years. As a result, constellations that consist of the current stellar array may be destroyed by advancing or dating tens of thousands of years. On the other hand, a constellation picture depicts an animal or the like associated with the current arrangement of stars when viewed from the earth. Therefore, if a constellation picture is overlaid on a constellation in which the arrangement of stars is broken, an unnatural image will result.
[0005]
In addition, in the effect of pseudo-space flight, since the projection position of a star changes due to the movement of the observation position, parallax due to movement of the viewpoint occurs. When simulating a long-distance flight, the arrangement of the stars is destroyed with the movement due to the influence of the parallax. Therefore, as in the case of stellar eigenmotion, if a constellation picture is overlaid on a constellation in which the arrangement of stars is broken, an unnatural image will result.
[0006]
Further, a planetarium projection device sometimes projects polar coordinate lines such as an equator line and an ecliptic line. However, these polar coordinate lines are drawn with reference to the earth and the sun. Therefore, if these polar coordinate lines are projected at an observation position far from the earth or the sun during the performance of the pseudo-space flight, an extremely unnatural image will result.
[0007]
Further, in the conventional planetarium projection device, it is necessary for the operator himself to judge that the image has become unnatural, and to disable projection assistance for explanations such as constellation pictures. Therefore, the operation was very advanced for an operator who had a complicated operation and had little astronomical knowledge. In addition, despite the fact that the image is unnatural, a projection operation for commentary assistance may be performed, and an inaccurate commentary may be given to the audience.
[0008]
The present invention has been made to solve the problems of the above-mentioned conventional planetarium projector. In other words, the issue is that the planetarium can produce natural motion of stars and pseudo-space flight, and maintain a natural image for the audience without requiring the operator to have advanced astronomical knowledge. An object of the present invention is to provide a program for a projection device and an astronomical simulator.
[0009]
[Means for Solving the Problems]
The planetarium projector designed to solve this problem is a planetarium projector that can produce at least one of pseudo-space flight and natural motion of celestial bodies, and provides a description of Hoshino based on the current time or current position. A projection judging means for judging whether or not the auxiliary image to be assisted can be projected; and if the projection judging means determines that projection is impossible, a video not including the auxiliary image is created, and the projection judging means judges that the projection is possible. In this case, there is provided an image creating means for creating an image including the auxiliary image, and a projecting means for projecting the image created by the image creating means on a screen.
[0010]
Also, the astronomical simulator program of the present invention provides a computer for an astronomical simulator capable of producing at least one of a pseudo-space flight and an intrinsic motion of an astronomical object. A display determination function for determining whether an image can be displayed, and an image not including an auxiliary image when the display determination function determines that the image cannot be displayed, and when the display determination means determines that the image can be displayed. Implements an image creation function for creating an image including an auxiliary image.
[0011]
That is, in the present invention, the projection determining means determines whether or not to project a supplementary image such as a constellation picture, a constellation line, or so-called commentary assistance, based on the current time or the current position. That is, the projection determination means determines whether the current time or the current position is an unnatural image for the audience. Note that the current time and the current position here are the time and the position in the performance of the pseudo-space flight or the characteristic motion of the celestial body, and are not the actual time and the position of the spectator. Then, an image according to the determination result is created by the video creating unit. In other words, if it is determined that the video is unnatural, no video including commentary assistance is created. Then, the created video is projected on a screen via a projection unit. As a result, a natural image can be maintained for the audience without an unnatural image. In addition, the planetarium projection device itself automatically determines whether or not the commentary projection can be performed. Therefore, the operator does not require advanced astronomical knowledge. The number of projection means may be one or more.
[0012]
Further, the planetarium projection device of the present invention has an operation unit for selecting whether or not to display the auxiliary image on the screen, and an operation unit when the projection determination unit determines that the auxiliary image cannot be projected. Operation control means for suppressing selection of the auxiliary image, wherein the image creation means, when the projection determination means determines that projection is not possible, regardless of the content of the selection of the operation means, does not include the auxiliary image. It is better to create That is, it is possible to select whether or not to display the auxiliary image on the screen by the operation means. This selection is made by an operator. As means for suppressing, for example, the selection button of the auxiliary image is hidden. Alternatively, the display color of the selection button of the auxiliary image may be changed. Further, the input of the selection button may be invalidated. As a result, the operator can identify the commentary assistant that becomes an unnatural image when projected. For this reason, it is possible to prevent a commentary assistant that is an unnatural image from being projected by mistake.
[0013]
Further, it is more preferable that the projection determining means of the planetarium projection device of the present invention determines whether or not the auxiliary image can be projected based on a time difference between the reference time and the current time. As a result, the display on the screen or the operation screen is automatically switched when the age of tens of thousands of years is advanced or traced back, that is, when a unique motion of the celestial body is performed. Thereby, an unnatural image does not occur.
[0014]
Further, it is preferable that the projection determining means of the planetarium projector of the present invention determines whether or not the auxiliary image can be projected based on a distance from the reference celestial object to the current position. As a result, the display of the screen or the operation screen is automatically switched when the current position is moved, that is, when the effect of the pseudo space flight is performed. Thereby, an unnatural image does not occur.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0016]
[First form]
As shown in FIG. 1, the planetarium device of this embodiment has a dome screen 1 and a projection device 10 installed below the center thereof. Further, the projection device 10 includes an image control unit 2, an image projection unit 3, a fisheye lens 4, an operation unit 5, and a speaker 6. The image control unit 2 controls a video image projected on the dome screen 1. The video control unit 2 can also control audio and the like to be broadcast in the planetarium facility. The image projection unit 3 is for projecting a video image on the dome screen 1. The fisheye lens 4 is a lens for projecting a video image on the entire dome screen 1. The operation unit 5 is used by an operator through an operation panel to set video contents during or before the demonstration. The operation panel of the operation unit 5 corresponds to, for example, a touch panel. A plurality of buttons are displayed on the operation panel of the operation unit 5, and the operator can select various functions by using the buttons. The selectable functions include so-called commentary assist functions such as constellation pictures, constellation lines, and polar coordinate lines, as well as simulation functions such as natural motion of stars and pseudo-space flight. It is necessary to set a target time in advance in order to produce a natural motion of a star. In addition, in order to perform the effect of the pseudo-space flight, it is necessary to set a destination (including a stopover) in advance. Note that the target time and the destination can be set by the operation unit 5 during the demonstration.
[0017]
The video control unit 2 of the planetarium apparatus shown in FIG. 1 includes a control unit 21, a data storage unit 22, a video memory 23, a video generation unit 24, and an audio generation unit 25, as shown in the block diagram of FIG. It has. The control unit 21 performs video control, audio control, lighting control, and the like in accordance with commands from the operation unit 5 and the like. The data storage unit 22 stores data necessary for control and files necessary for projection and the like. The stored data includes, for example, the brightness of each celestial body, information on eigen motion, the names and arrangements of each constellation. The stored files include, for example, photographic images of celestial bodies and constellations. The image generation unit 24 generates an image to be projected on the dome screen 1. The generated video is sent to the video projection unit 3 and projected on the dome screen 1. The sound generation unit 24 generates sound to be broadcast in the planetarium facility. The generated sound is broadcasted through the speaker 6 to the planetarium facility.
[0018]
Next, the operation of the planetarium apparatus according to the present embodiment for producing the intrinsic motion of a star will be described. In the production of the natural motion of a stellar, a process of advancing (or going back) the simulation time T (hereinafter referred to as “current time T”) and changing the position of the celestial body with the elapse of the time is performed. The operator sets the target time Ts using the operation unit 5 and instructs the start of the stellar intrinsic motion. Note that the target time Ts may be a future time or a past time. Then, the image control unit 2 receiving the instruction creates an image in which the current time T is advanced and the position of the celestial body is gradually changed. Further, the display of the commentary assistance and the display of the operation panel of the operation unit 5 are switched according to the passage of time. Hereinafter, the processing of the present invention when the current time T is advanced will be described based on the flowchart of FIG.
[0019]
First, the current time T is obtained (S11). Next, it is determined whether or not the acquired current time T is within a preset limit time (S12). That is, whether or not the time T is later than the future upper limit time T1 (for example, 00:00:00 on January 1, AD7001), and whether the past lower limit time T2 (for example, BC3000 year It is determined whether or not the time is before (00: 00: 00: 00 on January 1). If the time T is out of the range (S12: NO), it is determined whether or not a constellation picture is projected (S13). If the constellation picture is being projected (S13: YES), the constellation picture is not projected (S14). After the processing in S14 or when the constellation picture is not projected (S13: NO), the operation buttons on the operation section 5 related to the constellation picture are prohibited (S15). Specifically, the display color of the operation button is changed, and the input of the operation button is invalidated. The operation button may be hidden. After the processing in S15 or when the time T is within the range (S12: YES), it is determined whether or not the current time T has reached the target time Ts (S16). If the target time Ts has not been reached (S16: NO), the process returns to S11 and repeats the previous processes. If the target time Ts has been reached (S16: YES), the processing at the elapse of the time is ended. With this processing, the display of the dome screen 1 and the operation unit 5 is automatically switched with the current time T.
[0020]
The limit time of the time T is set as a threshold common to all constellations in the process of FIG. 3, but may be set for each constellation. In this manner, the display on the dome screen 1 and the operation unit 5 can be switched for each constellation.
[0021]
Next, a display example on the dome screen 1 and a display example of the operation unit 5 in the case of performing a stellar natural motion will be described. FIG. 4 is a diagram showing a projection image on the dome screen 1 when the current time T is advanced. FIG. 4A shows the star field at the start of the production of the intrinsic motion of the star. In addition, a constellation picture and a constellation line of Canis are projected as a supplementary explanation. If the start time is 21:00:00 on January 15, 2000, the display on the operation panel is a screen as shown in FIG. On this screen, it is possible to select commentary assistance for the constellations. The contents of the commentary assistance include, for example, a constellation picture, a constellation line, a constellation name, and the like. In addition, the constellation is not limited to Canis, and other constellations can be selected. The screen also displays the current time and the observation position during simulation (hereinafter, referred to as “current position”).
[0022]
FIG. 4B shows a star field 3000 years after the time in FIG. 4A. In this star field, the arrangement of celestial bodies is changed compared to the star field in FIG. 4A due to the intrinsic motion of the star. For example, the position of a stellar indicating the forearm of Capricornis has changed. FIG. 4C shows the Hoshino in AD7000 with the time further advanced. When the time is advanced to this point, the arrangement of the celestial bodies differs considerably from the point in time in FIG. It is very difficult to associate the canopy with the arrangement at this point. Therefore, the constellation picture is automatically turned off. Specifically, as described above, the upper limit time T1 and the lower limit time T2 are provided, and non-projection is automatically performed depending on whether the time is within the range. Further, the display on the operation panel is switched to a screen as shown in FIG. That is, the display of the buttons related to the constellation picture is automatically switched. Further, input of a button related to a constellation picture is not accepted. Therefore, the operator does not project the constellation picture in an unnatural state.
[0023]
In the above-described processing when the time has elapsed (FIG. 3), the display is switched according to the current time T, but the display can be switched according to the position of the celestial body. Hereinafter, the process of switching the display according to the position of the celestial body will be described based on the flowchart of FIG.
[0024]
First, the current time T is obtained (S21). Next, the projection position of the landmark celestial body at the acquired current time T is calculated (S22). In this processing, the landmark objects are assumed to be three stars, Sirius, α Centauri, and Arcturus. The landmark objects are not limited to this. Also, the number of landmark objects is not limited to three. Next, a shift amount (difference) between the projection direction at the simulation time T and the projection direction at the reference time is calculated for the landmark objects (S23). In this processing, the reference time is set to 2000. It should be noted that any other time may be used as long as it is not unnatural when the constellation picture is displayed. Next, it is determined whether or not the calculated shift amount is within an allowable range (S24). For example, if even one of the three landmarks has a deviation of 5 degrees or more, it is determined that the whole is outside the allowable range. If the amount of deviation is out of the allowable range (S24: NO), it is determined whether or not a constellation picture is projected (S25). If the constellation picture is being projected (S25: YES), the constellation picture is not projected (S26). After the processing of S26 or when the constellation picture is not projected (S25: NO), the operation of the operation button of the constellation picture is prohibited by the operation unit 5 (S27). After the processing in S27 or when the deviation amount is within the allowable range (S24: YES), it is determined whether or not the current time T has reached the target time Ts (S28). If the target time Ts has not been reached (S28: NO), the process returns to S21 and repeats the previous processes. If the target time Ts has been reached (S28: YES), the processing at the elapse of the time is ended. In this process as well, the display on the dome screen 1 and the operation unit 5 can be switched according to the current time T as in the process shown in FIG.
[0025]
Next, the operation of the planetarium apparatus according to the present embodiment for effecting pseudo-space flight will be described. In the effect of the pseudo-space flight, a process of moving the current position P and changing the position of the celestial body with the change is performed. The operator sets the destination Ps with the operation unit 5 and instructs the start of the effect of the pseudo-space flight. Then, the image control unit 2 receiving the instruction creates an image in which the current position P is moved and the position of the celestial object is changed. Further, the display of the commentary assistance and the display of the operation panel of the operation unit 5 are switched according to the change. Hereinafter, the processing of the present invention when the current position P is moved will be described based on the flowchart of FIG.
[0026]
First, a distance D from the reference celestial object to the current position P is calculated (S31). For example, the sun and the earth correspond to the reference celestial body. Next, it is determined whether or not the calculated distance D is equal to or less than a preset projectable distance D1 (S32). In this processing, the projectable distance is set in units of 100 astronomical units. If the distance D is equal to or less than the projectable distance D1 (S32: NO), it is determined whether a constellation picture is being projected (S33). If the constellation picture is being projected (S33: YES), the constellation picture is not projected (S34). After the processing of S34 or when the constellation picture is not projected (S33: NO), the operation button of the constellation picture on the operation unit 5 is prohibited (S35). After the processing in S35 or when the distance D is within the allowable range (S32: YES), it is determined whether or not the current position P has reached the destination Ps. If it has not reached the destination Ps (S36: NO), the process returns to S31 and repeats the previous processes. If it has reached the destination Ps (S36: YES), the processing at the time of moving the current position is ended. By this processing, the display of the dome screen 1 and the operation unit 5 is automatically switched with the movement of the current position P.
[0027]
In the above-described processing, the display is automatically switched for the constellation picture, but the explanation assistance to be switched is not limited to the constellation picture. For example, when polar coordinate lines such as equatorial coordinates and ecliptic coordinates are displayed, such polar coordinate lines can be automatically switched together with the constellation picture. Also, it is not necessary to switch the video for all commentary assistance. For example, the display on the dome screen 1 may not be switched for the constellation line. In this case, the display on the operation unit 5 does not need to be switched.
[0028]
Next, a display example on the dome screen 1 and a display example on the operation panel of the operation unit 5 when the effect of the pseudo space flight is performed will be described. FIG. 9 is a diagram showing a projection image on the dome screen 1 when the current position P has moved. FIG. 9A shows a production start point of the pseudo-space flight, specifically, a star field over the earth. In addition, a constellation picture and a constellation line of Cygnus are projected as a commentary aid. If the current position P is set above the earth, the display of the operation panel is a screen as shown in FIG. If the current position P is the earth, polar coordinate lines can be displayed. As a screen of the operation panel for selecting a polar coordinate line, for example, there is one shown in FIG.
[0029]
FIG. 9B shows a star field when the target point Ps is set to Deneb in Cygnus and the observer's viewpoint is rotated toward Deneb. FIG. 9C shows a starry field at a point where a pseudo-space flight to Deneb is started and the reference celestial object is at least 100 astronomical units away. In the star field of FIG. 9 (C), the arrangement of the celestial bodies differs considerably from the start point of the pseudo-space flight (over the earth). Therefore, the constellation picture is automatically turned off. Specifically, as described above, non-projection is automatically performed based on whether or not the distance D from the reference celestial object exceeds the projectable distance D1. Further, the display on the operation panel is switched to a screen as shown in FIG. That is, the display of the constellation button is automatically switched. The screen for selecting a polar coordinate line is also switched to a screen as shown in FIG. That is, it becomes impossible to select the display of the polar coordinate line. Therefore, the operator does not project a constellation picture or a polar coordinate line in an unnatural state.
[0030]
Although the display is switched according to the distance D between the current position P and the reference celestial body in the above-described processing at the time of moving the current position (FIG. 8), the display can be switched according to the celestial body position. Hereinafter, the process of switching the display according to the position of the celestial body will be described based on the flowchart of FIG.
[0031]
First, the current position P is obtained (S41). Next, the projection direction of the landmark celestial body (Sirius, α-Centauri, Arcturus, etc.) at the acquired current position P is calculated (S42). Next, a shift amount (difference) between the projection direction at the current position P and the projection direction at the reference position is calculated for the landmark celestial body (S43). Here, the projection direction at the reference position is the reference position, that is, the projection direction viewed from the earth. Next, it is determined whether or not the calculated shift amount is within an allowable range (S44). If the deviation is out of the allowable range (S44: NO), it is determined whether or not a constellation picture is projected (S45). If the constellation picture is being projected (S45: YES), the constellation picture is not projected (S46). After the processing of S46 or when the constellation picture is not projected (S45: NO), the operation button of the constellation picture is changed to the operation prohibition by the operation unit 5 (S47). After the processing in S47 or when the deviation amount is within the allowable range (S44: YES), it is determined whether or not the current position P has reached the target location Ps (S48). If the target location Ps has not been reached (S48: NO), the process returns to S41 and repeats the previous processes. If the target position Ps has been reached (S48: YES), the processing at the time of moving the current position P ends. In this process as well, the display on the dome screen 1 and the operation unit 5 can be switched with the movement of the current position P as in the process shown in FIG.
[0032]
As described above in detail, in the planetarium apparatus of the present embodiment, the display of the dome screen 1 and the operation unit 5 is automatically switched with the current time T during the production of the specific motion of the star. That is, the commentary projected on the dome screen 1 is automatically set to non-projection. Further, regarding the operation panel of the operation unit 5, the display of the buttons related to the commentary assistance is automatically switched. In addition, the display of the dome screen 1 and the display of the operation unit 5 are automatically switched with the movement of the current position P during the performance of the pseudo space flight. As a result, there is no need to project commentary assistance such as constellation pictures in an unnatural state. Also, the operator does not erroneously display the commentary assistance. Further, since the display is automatically switched, no burden is imposed on an operator having little astronomical knowledge. Therefore, a planetarium projection device that can produce natural motion of stars and pseudo-space flight is possible, and can maintain a natural image for the audience without requiring advanced astronomical knowledge to the operator. I have.
[0033]

In the video generation unit group 52, each video generation unit corresponds to each of the projection units 11 to 16, and generates a video corresponding to each projection unit. The video adjustment unit 53 performs a joining process on an overlapping portion of the six divided areas. The adjusted image is sent to each projection unit and projected on the dome screen 1.
[0035]

Then, during these effects, the integrated control unit 50 can perform the processing shown in FIGS. 3 and 8. Therefore, it is possible to automatically switch the display of the dome screen 1 and the operation unit 18 with the passage of time during the production of the natural motion of the star. Further, it is possible to automatically switch the display of the dome screen 1 and the operation unit 18 with the movement of the current position during the performance of the pseudo space flight. Therefore, the planetarium projection device of the present embodiment does not require the operator to have high astronomical knowledge. In addition, a natural image can be maintained for the audience.
