Description

Planetarium production system and method

The present invention relates to a planetarium production system and method, and more particularly to a planetarium production system and method in a planetarium that projects a starry sky onto a dome-shaped screen.

An example of a conventional planetarium is described in Japanese Patent No. 5105917. Japanese Patent No. 5105917 describes a composite planetarium system including an optical stellar projector and a digital image device including an image generator and a projector for image projection. This composite planetarium system projects bright stars with an optical stellar projector and projects images of stars darker than bright stars with a projector for image projection, so that a beautiful and realistic starry sky can be reproduced while producing stars. It is a multifunctional complex planetarium system that enables various video effects such as blinking and coloring stars.

In recent years, various experiential learning has been emphasized in elementary schools based on the curriculum guidelines, and as part of science education, off-campus learning at off-campus facilities such as planetariums and science museums is being actively carried out.

However, not all children who have been led by the planetarium in elementary school class units or grade units are always interested in the starry sky from the beginning, and it is difficult to concentrate for a long time in the lower grades. Sometimes I made noise or fell asleep without listening to the explanation of the starry sky projected on the screen in the planetarium. For this reason, in the screening of planetariums, various explanations and projection programs have been devised in order to attract children's interest and enhance the learning effect. For example, the teacher who has led the children operates the planetarium and gives explanations to motivate the children to learn.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a planetarium production system and a method capable of increasing the consciousness of participation of spectators in a planetarium that projects a starry sky on a dome-shaped screen.

In order to achieve the above object, the planetarium production system of the present invention is a planetarium production system in a planetarium that projects a starry sky onto a dome-shaped screen, and includes a database in which a self-portrait of an audience is stored. It is characterized by including a digital image device that captures a self-image, generates an audience image including at least a part of the self-image, and projects an image including the audience image on the screen.

Further, the planetarium production method of the present invention is a planetarium production method in a planetarium that projects a starry sky onto a dome-shaped screen, and captures a self-portrait of an audience to generate an audience image including at least a part of the self-portrait, and the audience It is characterized in that an image including an image is projected on the screen.

According to the planetarium production system and method of the present invention, in a planetarium that projects a starry sky on a dome-shaped screen, the audience's sense of participation is effectively raised by projecting an audience image based on the audience's self-portrait on the screen as an alter ego of the audience. It is possible to provide an image projection system and a method that can be enhanced.

Hereinafter, the planetarium production system and method according to the embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a schematic view of the planetarium effect system according to the embodiment of the present invention. The planetarium effect system of the present embodiment is a planetarium effect system in a planetarium that projects a starry sky onto a dome-shaped screen 10. The planetarium production system takes in the self-portrait from the database 2 and the database 2 in which the self-portrait drawn by the audience is stored, generates an audience image including at least a part of the self-portrait, and projects the image including the audience image on the screen 10. A video device 3 is provided.

The database 2 may be composed of a storage medium such as an internal memory or a hard disk, or may be composed of a USB memory.

Further, in the present embodiment, the optical star projector 4 is installed in the center of the planetarium dome. The optical star projector 4 has a function of projecting a star brighter than a certain luminosity (hereinafter referred to as a bright star), for example, a bright star of 2.0 mag or higher on a dome-shaped screen 10. The optical stellar projector 4 and the digital imaging device 3 are integratedly controlled by the controller 30.

On the other hand, the digital image device 3 generates an image of a starry sky including a star other than a bright star (hereinafter referred to as a faint star), for example, a star darker than 2.0 mag, and projects the image on the screen 10. The digital imaging device 3 also projects the peripheral scenery 12 or its silhouette forming a skyline on the horizon 11 around the screen 10 onto the screen 10.

The digital image device 3 includes an image generator 31 and three projectors 32 (32a, 32b, 32c) for projecting images arranged around the dome-shaped screen 10.

The video generation device 31 takes in each of these self-portraits from the database 2 and generates an audience image including at least a part of each of these self-portraits. As the spectator image, the self-portrait of the whole body may be used as the spectator image of the whole body as it is, or only a part of the self-portrait, for example, the head (face part) may be used as the spectator image.

Then, each projector 32 (32a, 32b, 32c) projects an image including these audience images on the screen 10.

FIG. 2 shows a divided projection area on a dome-shaped screen by a projector. As shown in the figure, the

projectors

32a, 32b, and 32c are assigned ranges A, B, and C in which the entire circumference of the screen 10 is divided into three equal parts, respectively. Each of the

image projection projectors

32a, 32b, and 32c projects an image into the assigned ranges A, B, and C, respectively.

Although the present embodiment includes three

projectors

32a, 32b, and 32c, four or more projectors may be arranged.

FIG. 3 shows an example of the audience image 5 (5a, 5b, 5c) projected on the dome-shaped screen 10. In the figure, as the audience image 5, a male child image 5a, a female child image 5b, and a leading teacher image 5c are projected on the horizon 11 around the screen 10. The male child image 5a, the female child image 5b, and the leading teacher image 5c read the whole body self-portrait (for example, a portrait) created in advance by the children who are the spectators of the planetarium and the leading teacher, which have been led by the planetarium, with a scanner. What is stored in the database 2 is projected as it is as a whole-body audience image. The audience image is generated by transparently processing the periphery of the scanned whole-body self-portrait and extracting a range of a person or a further part of the range by a computer.

Although FIG. 3 shows the male child image 5a, the female child image 5b, and the leading teacher image 5c as representatives, it is preferable that the audience image of all the children led by the planetarium is projected on the screen 10. .. Further, it is preferable that the audience images of all the children are projected side by side on the surrounding scenery 12 forming the skyline on the horizon 11 around the screen 10 before or at the start of the explanation of the planetarium. Further, by arbitrarily moving the coordinates for arranging the spectator image of the child for each child, it is possible to produce an effect as if the children were walking.

In the case of a chartered screening of a school group at the planetarium, the independent participation in learning at the planetarium has started from the stage where the child draws a self-portrait at the school in advance. Prior to the screening of the planetarium, it is expected that the children's sense of participation and uplifting will be enhanced and their motivation for learning will be improved by creating a self-portrait projected on the planetarium.

Then, in the planetarium, when the audience image based on the self-portrait created by the child is projected on the dome-shaped screen 10, the child searches for his / her own audience image on the screen 10, and as a result, the child's interest is effectively displayed on the screen 10. Can be turned. Then, by projecting the audience image, which is the alter ego of the child, on the screen 10, the child's awareness of participation can be effectively increased. In particular, by projecting the audience image together with the starry sky, one's alter ego becomes one with the starry sky, and the child's awareness of participation can be further enhanced. As a result, it is possible to attract children's interest in the explanation of the starry sky and the like projected on the dome-shaped screen 10 and improve the learning effect in the planetarium.

Here, the information stored in the database 2 will be described with reference to FIG.

In the example shown in the figure, the database 2 includes the skyline image database 2a, the image database 2b, the name database 2c, and the question database 2d.

The skyline image database 2a stores images of the surrounding scenery constituting the skyline shown in FIGS. 1 and 2, and the digital image device 3 reads the image of the surrounding scenery from the database 2 and projects it on the screen 10. To do.

The image database 2b stores full-body self-portraits (for example, caricatures) created in advance by the children who are the spectators of the planetarium and the teacher, which are captured by a scanner. Each child's self-portrait is given a child's attendance number as an identifier.

The identifier is not limited to the attendance number, and any suitable identifier can be used. In addition, it is preferable to scan the self-portraits of children and the like created in the classroom of the school and convert them into data. The self-portrait information converted into data may be sent to the planetarium database 2 via a communication line, or may be stored in a storage medium such as USB and brought to the planetarium to be stored in the database 2. Alternatively, the self-portrait may be brought to the planetarium as it is, scanned by the planetarium, and stored in the database 2.

In addition, the name database 2c stores information on the names of each child and the like. The name of each child or the like is associated (linked) with the self-portrait of the image database 2b via the attendance number as an identifier.

The question database 2d stores the questions to be asked in the explanation in the planetarium and their answers. In the example shown in FIG. 4, the question database 2d stores the question "What is the largest planet in this?" And the data "Jupiter" of "A" as the answer.

Further, as shown in FIG. 5, the database 2 may store the birthday database 2e and the constellation database 2f in addition to the above databases 2a to 2d or instead of the name database 2c.

The birthday database 2e stores the names and birthday information of each child, etc., and each child's name is given a child's attendance number as an identifier.

In addition, the constellation database 2f stores information on the twelve constellations of the zodiac and the period of each constellation. The period of each constellation of the Zodiac is the period in which the sun is located in the direction of each constellation on the celestial sphere as seen from the earth.

The so-called zodiac signs used in astrology may be adopted as the zodiac constellations. However, while the celestial range of the ecliptic zodiac is defined by the International Astronomical Union as part of the 88 constellations, the ecliptic zodiac divides the ecliptic into 12 equal parts and assigns them to 12 constellations. Therefore, the ranges of the Zodiac constellations and the Zodiac signs do not exactly match.

Then, through the birthday, the names of each child in the birthday database 2e are associated with the birthday constellations of the twelve zodiac constellations. In the example shown in FIG. 5, March 11, which is the birthday of the child with attendance number 1 in the birthday database 2e, is included in the period from February 19 to March 20 in Taurus, and attendance number 2 April 21st, the birthday of the child, is included in the period from April 20th to May 20th in Taurus.

Therefore, the self-portrait of each child, etc. in the image database 2b is associated with the birthday constellation of the Zodiac constellation in the constellation database 2f, using the attendance number and birthday as keys.

Next, with reference to FIG. 6, an example of production in the planetarium will be described. In this production example, the database 2 has the birthday database 2e and the constellation database 2f shown in FIG. 5, and as described above, a self-portrait of a child or the like as an audience and the birth of a child or the like among the twelve constellations of the zodiac. It is associated with the birthday constellation where the sun is located on the day.

Then, the digital image device 3 projects the audience image generated from the self-portrait at the position of the birthday constellation associated with the self-portrait among the constellations projected on the screen.

FIG. 6 is a schematic view of the audience image projected on the zodiac constellation. In the figure, only the head of the child's whole body self-portrait is projected as an audience image.

When projecting a caricature as a child's alter ego on the corresponding birthday constellation, it is advisable to project the caricature at the position of the stars that make up the birthday constellation. Specifically, it is advisable to superimpose and project a child's caricature on the bright star position in order from the α star of each constellation. For example, in the example shown in FIG. 6, a portrait 5b of the head of a boy with attendance number 1 is projected on Arlesha, which is the α star of Pisces, as an audience image, and Aldebaran, which is the α star of Taurus. On top of that, a portrait 5a of a girl child with attendance number 2 is projected as an image of the audience. As a result, the position of the α star in each constellation of the Zodiac constellation can be strongly impressed on the child, and the learning effect in the planetarium can be improved.

When projecting a caricature at the position of the birthday constellation, it is also possible to project the caricature at a position other than the stars constituting the birthday constellation within or near the birthday constellation.

In FIG. 6, the sun image S is projected on Aries in order to explain that the sun is located in the direction of Aries on the celestial sphere from the end of March to the middle of April. ing.

Then, move the sun image S along the ecliptic 7 to the position on the celestial sphere of the sun on the birthday of the boy with attendance number 1, and move the sun image S near the caricature 5b, which is the alter ego of the boy. Or, if you project it on the caricature 5b, you will strongly impress and understand the basic knowledge of astronomy that it will be difficult to see your birthday constellation because the sun is located in your birthday constellation at your birth. It is effective for making it. This makes it possible to improve the learning effect of the planetarium.

Further, FIG. 6 shows an example in which a child's caricature is projected on the zodiac constellation, but a child's caricature as a self-portrait of the audience is projected on a constellation other than the zodiac constellation or a celestial body. You may.

In that case, for example, in the database 2, it is advisable to associate the self-portrait of the child with a specific celestial body or constellation projected on the screen 10. For example, the database 2 is provided with a constellation / celestial body database that stores information on constellations such as Orion and celestial bodies such as the river and celestial clouds. It is good to associate. Further, each name in the name database 2c associated with the image database 2b may be associated with a specific constellation or celestial body in the constellation / celestial body database.

Then, the digital image device 3 may project the audience image 5 generated from the self-portrait onto the position of the celestial body or constellation associated with the self-portrait among the celestial bodies or constellations projected on the screen 10.

Next, with reference to FIG. 7, another production example in the planetarium will be described. In this production example, a terminal device that allows children and the like as spectators seated in the planetarium to input information is further provided. In the example shown in FIG. 4, a mobile terminal (mobile terminal) 6 is shown as a terminal device.

As the mobile terminal 6, a mobile terminal such as a smartphone owned by the spectator may be used, or the mobile terminal may be distributed to the spectator and collected later. Further, the terminal device is not limited to wireless, and may be connected to the planetarium production system by wire, for example, the controller 30, or may be pre-installed in each seat of the planetarium such as a response analyzer. When using such equipment, it is desirable to associate the seats with the children by, for example, seating the children in the order of attendance numbers.

Then, as shown in FIG. 4, the operation result of the terminal device such as the mobile terminal 6, for example, the answer input information of the quiz is aggregated in the controller 30 of the planetarium production system.

In this production example, in the database 2, each image of the image database 2b is associated with each mobile terminal 6. FIG. 7 shows the projection position of the audience image generated from the self-portrait associated with the mobile terminal 6 in which the digital video apparatus 3 has been subjected to a specific information input operation (for example, a correct answer input operation). As such, it is selectively moved on the screen and / or the size of the audience image is selectively changed.

Specifically, in the question database 2d, the girl child with attendance number 2 selects the correct answer "A" or "Jupiter" on the mobile terminal 6 for the question "What is the largest planet in this?" An example of the effect when the answer input operation is performed will be described.

In such a case, the controller 30 aggregates the contents of the answer input operation in each mobile terminal 6, and the video generator 31 displays the audience image 5b, which is the alter ego of the girl child with the attendance number 2 who has input the correct answer, in FIG. 7. As shown, it is moved upward from above the horizon 11 and projected. In the example shown in FIG. 7, the decoration surrounding the female child's audience image 5b and the character display of "correct answer !!" are also projected. In addition, the female child's audience image 5b may be moved upward and enlarged and projected. In this way, by not only answering the quiz-style question but also moving and / or enlarging the audience image of the correct answerer, it is possible to make the audience image stand out and strongly impress the correct answer, and the participation of the audience. It is possible to raise awareness and improve the educational effect.

In the example shown in FIG. 7, an example in which the audience image of the correct answerer can be moved and pointed to when answering a quiz-type question has been described, but the digital image device 3 has a projection position of an arbitrary audience image at an arbitrary timing. Can be selectively moved on the screen 10 and / or the size of the audience image can be selectively changed.

Further, the desired audience image may be selectively moved on the screen 10 and / or the size of the audience image may be selectively changed by operating in the console space (controller 30) of the planetarium. ..

Next, with reference to FIGS. 8 and 9, the audience image obtained by transforming the self-portrait will be described.

FIG. 8 is a schematic diagram showing an example of creating a self-portrait. FIG. 9 is a schematic view of a deformed audience image projected based on the self-portrait shown in FIG.

In the present embodiment, the self-portrait 50 of the whole body of the boy is drawn on the mount 8 which is the predetermined paper shown in FIG. The mount 8 has a torso region 80, a head region 81 adjacent to the upper side of the torso region 80, a pair of

arm regions

82 and 83 adjacent to both sides of the torso region 80, and a lower side of the torso region 80.

Adjacent leg areas

84 and 85 are set. The torso of the self-portrait 50 is drawn in the body area 80, the head of the self-portrait 50 is drawn in the head area 81, and the left and right arms of the self-portrait 50 are drawn in the

arm areas

82 and 83. The left and right legs of the self-portrait 50 are drawn in the

leg areas

84 and 85.

The digital image device 3 has a body portion of the self-portrait portion drawn on at least one of the head region 81, the

arm regions

82 and 83, and the

leg regions

84 and 85 of the self-portrait 50 drawn on the mount 8. A spectator image deformed to rotate with respect to the region 80 is generated.

In the audience image 51b shown in FIG. 9, in the self-portrait 50 of the boy, the head drawn in the head region 81 is deformed so as to rotate with respect to the torso region so as to bend the neck, and the arm region. The torso region 80 is deformed so as to rotate with respect to the torso region so that the right arm drawn in 83 is swung diagonally upward, and the left foot drawn in the leg region 84 is opened outward. It is deformed so that it rotates with respect to. By moving each part of the body of the self-portrait, it is possible to produce a change as if the limbs of the self-portrait move or the direction of the head changes. In addition, each part of the body may be projected in a state of being moved and stationary, or may be projected in a state of being continuously moved.

In this way, by transforming the audience image 51b as the alter ego of the audience with respect to the self-portrait, it is possible to express a more dynamic and attractive self-portrait, and it is possible to more effectively enhance the participation consciousness of the audience. .. In addition, by deforming the audience image, it is possible to give the audience image a role as a pointer pointing to the star to be explained.

Although the embodiments of the present invention have been described above, various changes and modifications can be made within the scope of the present invention. In the above-described embodiment, an example of a production system in a composite planetarium including an optical star projector and a digital image device has been described. However, in the present invention, the planetarium is a digital type without providing an optical star projector. A projector may be used to project a star, or an optical star projector may be used to project a star including bright stars and faint stars, while a digital image device may be used to project a non-star celestial body or image. It may be.

The audience is not limited to children and students of the school group, and may be, for example, a pair of a resident of an elderly home and a child, or a family.

Further, the self-portrait is not limited to a picture drawn by the audience such as a portrait, and may be, for example, a photograph or computer graphics showing the audience.

Also, the audience image projected on the screen is not limited to still images. For example, when a particularly motivated child wants to move his / her self-portrait, he / she is made to draw a large number (for example, several to several tens of) self-portrait still images and create an animation composed of these still images. , This animation can also be projected on the screen as a video audience image.
