Description

Ferris wheel FERRIS WHEEL

The present invention relates to a Ferris wheel.

It is known that a Ferris wheel installed in an amusement park or the like is known (see, for example, Patent Document 1). This Ferris wheel has a rotating wheel and a plurality of pods arranged at a specific interval along the circumferential direction of the rotating wheel. The Ferris wheel slowly rotates while the passengers are carrying the passengers in the pod. Passengers in the pod can enjoy the changing landscape with a slow movement. And you can enjoy the distance around the apex.

However, the previous Ferris wheel was just a view of the scenery that was seen from the outside of the pod. Therefore, depending on the person, some people will feel bored. In particular, the former Ferris wheel has a lack of freshness in terms of people who are familiar with the local people or who have used it.

However, in recent years, a device that combines real-world space with virtual space in real time [Mixed Reality; including Augmented Reality and Augmented Virtuality] has been widely studied (see, for example, patents). Literature 2, 3). The device that prompts the composite reality is, for example, first photographs a real space by a camera portion such as a camera. Next, the device that prompts the composite reality sense superimposes the virtual image on the image (actual image) captured by the photographing portion to generate a composite image. Next, the device that prompts the composite reality sense outputs the composite image to the outside. In this way, the device that prompts the composite reality can provide a composite reality that the actual image and the virtual image are fused to the user who sees the composite image. In the devices of Patent Documents 2 and 3, a camera unit is attached to a head mounted display (HMD). Moreover, the actual image captured by the camera unit is immediately superimposed with the virtual image to produce a composite image. This composite image is then presented on a head mounted display device. Therefore, if walking is performed with the head mounted display device mounted, the virtual image is superimposed and displayed on the image corresponding to the viewpoint of the user. Thus, the head mounted display device can give the user a feeling that the virtual image exists in the real space.

However, if the user who walks and runs on the ground only uses such a device that can prompt the complex reality, the user can only enjoy the range of the surrounding scenery that can be seen on the ground, and cannot enjoy the complex reality.

The present invention has been accomplished in view of the above circumstances. It is an object of the present invention to provide a Ferris wheel that provides a composite reality with a range of cues that are not only a field of view on the ground but a wider range, while at the same time giving passengers in the pod a greater level of fun than simply looking at the scenery.

In order to solve the above problems, the Ferris wheel system of the present invention has the following configuration.

The Ferris wheel of the present invention has a plurality of nacelles 63, a photographing unit 1, and a control unit 3. The photographing unit 1 is provided in each of the nacelles 63. The configuration of the photographing unit 1 is for photographing the actual scenery outside the pod 63. The display unit 2 is provided in each of the nacelles 63. The control unit 3 is configured to superimpose a virtual image on a specific position of an actual image captured by the photographing unit 1, thereby generating a composite image. The control unit causes the composite image to be displayed on the display unit 2.

With such a configuration, the passenger of the nacelle 63 can be given a complex realistic feeling (including an expanded reality and an expanded virtual feeling) using a wide range of fields of view visible from the gondola 63 of the Ferris wheel. Moreover, the nacelle 63 does not continue to move only in the horizontal direction but also in the height direction. Therefore, it is possible to give a composite reality that is not available only to the viewpoint on the ground.

The control wheel 3, the memory unit 34, the virtual image deforming means 36, the image synthesizing means 33, and the image display means 35 are preferably included in the Ferris wheel of the present invention. The memory unit 34 stores a virtual image. The virtual image deforming means 36 changes the size and angle of the virtual image stored in the memory portion 34 in accordance with the position of the pod 63. The image synthesizing means 33 is configured to superimpose an image changed by the virtual image deforming means 36 on a specific position of the actual image photographed by the photographing section 1, thereby generating a composite image. The image display means 35 displays the image generated by the image combining means 33 on the display unit.

With such a configuration, the virtual image can be deformed in accordance with the movement of the nacelle 63. Thereby, the composite image can be made closer to the real person.

Further, the Ferris wheel of the present invention preferably includes a position detecting unit and a photographing direction detecting unit. The position detecting unit is configured to detect the position of the photographing unit 1. When the position detecting unit detects the position of the photographing unit 1, detection information is generated. The photographing direction detecting portion is configured to detect the photographing direction of the photographing portion 1. When the shooting direction detecting unit detects the shooting direction of the photographing unit 1, the shooting direction detecting unit generates the detecting information. The virtual image transforming means 36 changes the virtual image according to the detection information generated by the position detecting unit and the detection information generated by the shooting direction detecting unit.

With such a configuration, the positional calibration of the actual image and the virtual image can be performed relatively accurately.

Further, the Ferris wheel of the present invention further includes the control unit 3, The marker recognition means 30 and the position/orientation analysis means 32 are preferred. The marker identifying means 30 recognizes the specific object contained in the actual image as a marker. The position/orientation analysis means 32 is configured to analyze the position/orientation of the marker recognized by the marker recognition means 30. The memory unit 34 stores the virtual image in advance in association with the marker. The virtual image deforming means 36 changes the virtual image based on the position/posture information of the marker analyzed by the position/orientation analyzing means 32. When the control unit 3 recognizes the marker via the marker identifying means 30, the virtual image corresponding to the marker is acquired from the memory unit 34. Then, the virtual image acquired by the marker recognition means 30 from the storage unit 34 is changed by the virtual image transformation means 36. This changed image is superimposed on a portion of the marker corresponding to the actual image by the image synthesizing means 33, thereby generating a composite image. Next, the composite image is displayed on the display unit 2 via the image display means 35.

With such a configuration, the accuracy of the positional alignment of the actual image and the virtual image can be improved.

Moreover, the aforementioned virtual image is preferably a computer graphics image based on a landscape different from the modern era.

Thereby, for example, a building in the past history on the land or a future imaginary map or the like can be superimposed on the actual image to generate a composite image, and the passenger of the pod 63 can be given fun.

Further, in the Ferris wheel of the present invention, it is preferable that a virtual image of a plurality of different ages is stored in the memory portion. Further, each of the pods further has a setting unit 52 that can be set to a landscape of an arbitrary age. The control unit 3 acquires a virtual image corresponding to the age set by the setting unit 52 from the storage unit 34 and superimposes it on the actual image to generate an image. Display via image The means 35 displays the composite image on the display unit 2.

Thereby, the scenery of the age desired by the passenger of the pod 63 can be displayed via the display unit 2, and the passenger can be further enjoyed.

Further, in the Ferris wheel of the present invention, the camera unit 1 is preferably a camera. The camera system is disposed outside the nacelle 63. The composition of the camera can change the direction of the shooting. The pod 63 is preferably further provided with an operation unit that can change the photographing direction of the camera.

Thereby, the actual image of the viewpoint desired by the passenger of the car 63 can be displayed by superimposing the virtual image on the virtual image. Thus, the passenger can be given a sense of complex reality that utilizes a wider range of fields of view.

Further, it is preferable that the Ferris wheel of the present invention is provided in the head mounted display device with the display unit described above.

With the Ferris wheel of the present invention, the hint range of the composite reality can be more than just the viewpoint on the ground but a wider range, and at the same time, the passengers of the pod can be given more fun than simply looking at the scenery.

The embodiments of the present invention will be described below based on embodiments of the present invention.

The Ferris wheel of the first embodiment has a pair of support legs 60 as shown in FIG. A pair of support legs 60 are formed from the front and rear of the installation surface of the Ferris wheel. A rotating shaft 61 is horizontally placed on the upper end of the pair of support legs 60. The rotary shaft 62 is pivotally supported on the rotary shaft 61, whereby the rotary wheel 62 is rotatably mounted. The rotary wheel 62 is rotationally driven by a driving device (not shown) provided on the support leg 60. The rotating wheel 62 is formed into a substantially circular skeleton frame. At the outer end of the rotating wheel 62 along the circumference The pods 63 are hung in a direction separated by a specific interval. Each of the nacelles 63 suspended from the outer peripheral end portion of the rotary wheel 62 is attached to the rotary wheel 62 in a rotatable state. Thus, each of the pods 63 can be moved to a vertical position at any position of the rotating wheel 62. The rotation trajectory of each nacelle 63 is a substantially circumferential trajectory. At the lower end portion of the rotation locus of the nacelle 63, a riding path 64 for occupies the passengers is provided.

The outer shape of each of the nacelles 63 is formed into a substantially circular shape in a front view. Each of the nacelles 63 has a space required for passengers to board inside. Each of the nacelles 63 has a door 66 which is configured to open and close the inlet and outlet 65. A photographing portion 1 for photographing a landscape (actual scenery) outside the nacelle 63 is attached to a lower portion of the outside of the nacelle 63. The photographing unit 1 of the present embodiment is constituted by, for example, a CCD (Charge Coupled Device) photograph. Further, the photographing unit 1 is attached to an imaging direction driving device (not shown). The photographing unit 1 is configured such that the photographing direction driving device can perform the omnidirectional transformation in a state in which the photographing direction is from the horizontal direction to the slightly downward direction. In other words, the photographing unit 1 is configured to be rotatable 360 degrees in the horizontal direction by the photographing direction driving device. This camera unit 1 is connected to an operation unit 5 provided inside the nacelle 63 via a control unit 3 to be described later. The photographing direction of the photographing unit 1 can be changed by operating the operation unit 5. As shown in FIG. 3, the operation portion 5 is provided on the inner surface side opposite to the inlet and outlet 65 of the nacelle 63. Further, the operation unit 5 is disposed adjacent to the display unit 2. The operation unit 5 has an operation lever 51 that can be tilted. When the operation lever 51 is tilted, the photographing direction of the photographing portion 1 can be changed. The display unit 2 is constituted by a monitor. The display unit 2 is disposed so as to be slightly inclined upward. Thereby, it is configured such that its display surface faces the portion where the passenger's face is located. This display unit 2 is connected to the control unit 3. The display unit 2 is controlled via the control unit 3. The display unit 2 is provided at a substantially intermediate portion of the seat 67 of one of the opposing pairs. In the pod 63 A through window 68 is installed above the seat 67 to allow the passenger to view the external scenery (actual scenery) through the through window 68.

Moreover, the operation unit 5 is not fixed to the inner surface side of the nacelle 63 in a fixed manner as described above. As another example, it may be attached to the side surface of the display unit 2 through the electric wiring provided. At this time, the operation unit can move freely. Further, as another example, a receiving portion (not shown) may be newly provided on the inner side surface of the nacelle 63. In this case, an operation unit having a receiving unit can be further provided. The operating unit can be operated wirelessly.

The control unit 3 is configured to generate a composite image by superimposing a virtual image on a specific object of the actual image captured by the photographing unit 1. Further, the configuration of the control unit 3 is for displaying the composite image on the display unit 2. The control unit 3 superimposes the virtual image on the image captured by the photographing unit 1 to generate a new image. Further, the configuration of the control unit 3 is such that the image is displayed on the display unit 2 using a so-called composite reality (including an expanded realistic feeling and an expanded virtual feeling). The configuration of the control unit 3 of the present embodiment is for identifying a specific object of the scenery as a marker. Further, the control unit 3 superimposes the virtual image on the portion corresponding to the marker. That is, the control unit 3 uses a composite reality technology of the marker recognition type. The control unit 3 is constituted by a computer as shown in Fig. 1 . The computer is based on a microprocessor. The computer includes a marker recognition means 30, a marker storage section 31, a position/orientation analysis means 32, a virtual image transformation means 36, a storage section 34, an image synthesis means 33, and an image display means 35. The computer of the control unit 3 of the present embodiment is housed inside the seat 67 of each of the nacelles 63.

The marker identifying means 30 recognizes a specific object included in the actual scenery captured by the photographing unit 1 as a marker. The markers are based on specific objects contained in the actual scenery (eg, castle tracks, observatories, etc.) The characteristics of the 3-dimensional shape are identified. The information of the three-dimensional shape feature of this specific object is previously loaded in the marker storage unit 31. This marker storage unit 31 is composed of a memory. The marker storage unit 31 accommodates shape information of a plurality of different markers. The marker identifying means 30 recognizes whether it is equivalent to the memory in the mark by comparing the shape information stored in the marker storage unit 31 with the shape information of the specific object contained in the image captured by the photographing unit 1. Which of the plurality of markers of the object storage unit 31 recognizes the marker. The processing by the marker identification means can be achieved by performing image comparison exercises such as Dynamic Programming Matching (DP). In this process, the comparison with the loaded marker can be performed in more detail by increasing the resolution of the camera unit 1. Therefore, if the resolution of the photographing unit 1 is increased, the number of loaded markers can be increased. As the marker of the present embodiment, a city, a city track, an observatory, a tower, an apartment, an amusement facility, a station, a highway, and the like included in the actual image can be exemplified. Moreover, the identification of the marker can also identify the complex point by using the plurality of objects contained in the actual image as the marker. Further, as the marker of the present embodiment, the plurality of objects included in the actual image can be identified as a set of markers. The information related to the marker recognized by the marker identifying means 30 is transmitted to the position/orientation analyzing means 32 and the virtual image deforming means 36.

The position/orientation analysis means 32 is used to obtain the three-dimensional position and posture of the marker recognized by the marker recognition means 30. The position/orientation analysis means 32 is for calculating, for example, (a) information on the three-dimensional shape of the marker from the marker recognition means 30, and (b) on the object corresponding to the marker in the actual image. The position and posture of the marker against the image portion 1 were calculated in a three-dimensional position and shape. That is, the position/orientation analysis means 32 is used to analyze from The distance and angle from the camera 1 to the marker seen. In other words, the position/orientation analyzing means 32 is for analyzing the distance from the photographing section 1 to the marker. Further, the position/orientation analyzing means 32 also analyzes the angle between the direction in which the photographing portion 1 faces the marker and the horizontal direction. As information for defining the three-dimensional position and shape of the object corresponding to the marker, for example, a coordinate value of at least three feature points of the marker in the marker can be cited. Further, a method of calculating the three-dimensional position and posture of the marker can be performed by a conventional method. This method can be exemplified as follows: "Kato Boichi, Miyazaki Kazuo, Tachibana Keijiro: Position-positioning method for the purpose of generating a sense of expansion based on pattern matching generated immediately with characteristic images; Japanese virtual reality (virtual) The technique disclosed in "Theology", Thesis, Vol. 7, No. 2, pp. 119-128 (2002).

Further, the position/posture of the marker can be analyzed by the position detecting unit and the imaging direction detecting unit. The position detecting portion is configured to detect the position of the pod (that is, the position of the photographing portion 1). Thereby, the photographing direction detecting unit generates detection information indicating the photographing direction of the photographing unit 1. The position/orientation with respect to the photographing unit 1 is analyzed based on the detection information of the position detecting unit and the detection information of the photographing direction detecting unit. The position detecting unit may be constituted by, for example, a brake oscillator, a brake receiver, and a timer. The brake transmitter is disposed on the ride 64. The brake receiver is installed in each pod. The timer is used to determine the time from when the brake receiver receives the signal from the brake transmitter. The control unit 3 provided in each of the nacelles 63 calculates the position of each nacelle 63 based on the time information measured by the timer and the rotational speed information of the rotating wheel 62 that is rotated at a constant speed. As the shooting direction detecting unit, a sensor such as a geomagnetic sensor, a gyro sensor, or the like can be used. Further, the rotating wheel 62 of the Ferris wheel continuously rotates to move each of the nacelles 63 at a constant speed. Thus, the position/posture of the marker contained in the actual image is constantly changing.

Further, as the position detecting unit, it is of course possible to use a so-called GPS (Global Positioning System).

The position/orientation information analyzed by the position/orientation analysis means 32 is sent to the virtual image transformation means 36.

When the virtual image deforming means 36 acquires the information on the marker transmitted from the marker identifying means 30, the virtual image corresponding to the marker is acquired from the memory unit 34. This memory unit 34 is composed of a memory. The memory unit 34 is constructed such that the correspondence between the specific marker and the specific virtual image is memorized in advance. The virtual image is a computer graphics image (hereinafter referred to as a CG image) based on past scenery (for example, a city or a palace), and a CG image based on a prediction of a future scenery. The landscape is different from the modern era. In particular, when the past scenery is identified as a marker by a place of historic interest, the CG image of a city or palace that was previously built as a virtual image at the site may be superimposed on the actual image. Or as the state of war in the Warring States Period of Japan, the CG image is superimposed on the actual image. In addition, regarding the form of war in the Warring States Period of Japan, if the state of the war is presented by animation, it is better to give a sense of presence and fun. Of course, you can go up and down, for example, you can use the stone age residence as a CG image.

The virtual image warping means 36 changes the size and angle of the virtual image stored in the memory unit 34 in accordance with the position of the nacelle 63. Specifically, the virtual image deforming means 36 changes the virtual image in accordance with the position/posture information of the marker analyzed by the position/orientation analyzing means 32. When the virtual image deforming means 36 receives the information on the marker sent by the marker identifying means 30, the virtual image corresponding to the marker is acquired from the memory unit 34 as described above. Further, the virtual image deforming means 36 specifies the size and angle of the virtual image based on the information calculated by the position/orientation analyzing means 32. Then, the virtual image transforming means 36 deforms the virtual image according to the size and angle information of the specified virtual image. For this modification, it is preferable to provide an object (for example, a battlement, etc.) presented in a three-dimensional virtual image on the ground so as to be changed to be seen by the photographing portion 1 of the nacelle 63. The shape of the object on the ground is the same.

Further, the virtual image deforming means 36 may have a correction means for correcting the brightness of the virtual image in accordance with the brightness of the actual scenery, in addition to the above-described deformation of the size and angle of the virtual image. That is, by adjusting the brightness of the virtual image by using the correction means, the superimposition of the virtual image on the actual image does not cause an uncomfortable feeling.

The virtual image that has been deformed via the virtual image deforming means 36 in this manner is sent to the image synthesizing means 33.

When the image synthesizing means 33 acquires the information of the virtual image deformed by the virtual image deforming means 36, the deformed virtual image is superimposed on the portion corresponding to the mark of the actual image. Thus, the image synthesizing means 33 can generate a new image (composite image). The composite image generated here is sent to the image display means 35.

The image display means 35 is configured to display an image generated by the image combining means 33 on the display unit 2. When the image display means 35 receives the information of the composite image from the image combining means 33, the composite image is displayed on the display unit 2 disposed in the nacelle 63.

A series of control systems as such in the control unit 3 are continuously performed as the nacelle 63 moves. For example, as the pod 63 is raised, the relative posture of the markers also changes successively. However, the virtual image warping means 36 also changes the virtual image depending on the position of the pod. Thus, the virtual image is gradually reduced as the pod 63 is raised. And the virtual image is oriented toward the top. According to the above control, even if the image superimposed on the actual image is a virtual image, the image displayed on the display unit 2 can be made close to the actual image without limitation.

Moreover, the image displayed via the display unit 2 is a virtual image superimposed on the actual image. Therefore, it is synchronized with the surrounding environment such as weather conditions and brightness. Thereby, for example, the presence of the video image combined with the movement of the Ferris wheel is increased compared to the player.

That is, the Ferris wheel of the present embodiment can provide the passenger of the nacelle 63 with a complex realistic feeling of a wide field of view which can be seen from the nacelle 63 of the Ferris wheel. Moreover, the nacelle 63 does not move only in the horizontal direction, but also continuously moves in the height direction. Therefore, it is possible to give a composite reality that is not available only to the viewpoint on the ground.

Further, the Ferris wheel of the present embodiment is provided with an operation lever 51 that can freely change the imaging direction of the photographic unit 1 at the operation unit. Thus, a realistic sense of reality can be given to the scenery in which the passenger is looking. In this way, you can feel further fun.

Here, in the operation wheel 5 of the present embodiment, the setting unit 52 that can set the content of the virtual image may be further provided in the operation unit 5 in addition to the operation lever 51. The setting unit 52 has an epoch setting button for displaying a virtual image of a set era in a virtual image created by each era, and various characters (for example, monsters) for displaying a non-real existence of the illusory world. Various setting buttons such as the character setting button that can be set. The setting unit 52 is connected to the control unit 3. For example, when the operation time setting button is selected, the past scenery such as the Jomon period or the Yayoi era or the scenery indicating the future can be selected and displayed on the display unit. 2. A plurality of virtual images corresponding to the respective times are memorized in the memory unit 34 in advance. For example, when the age setting button is set to the safe era of Japan, the setting unit 52 sends a signal "Selected Heian Age" to the image synthesizing means 33. In this manner, the control unit 3 acquires, from the memory unit 34, a virtual image (for example, a CG image based on the safe city) corresponding to the flag of the Heian era and corresponding to the marker identified by the marker identifying means 30. Then, the virtual image deforming means 36 deforms the size/orientation (angle) of the virtual image according to the information of the position/orientation analyzing means 32 (that is, the position corresponding to the nacelle 63) by the image synthesizing means 33. The deformed virtual image is superimposed on the actual image to produce an image. The image generated here is sent to the image display means 35 and displayed on the display unit 2.

Since the setting unit 52 can set the image displayed on the display unit 2 to an era desired by the passenger, the history of the land related to the scenery that cannot be obtained only from the view of the ferris wheel can be obtained, and Arouse interest in history. Furthermore, since the buildings in history can be viewed from above, the passengers can feel the fun that has never been seen before.

Further, since the Ferris wheel of the present embodiment only needs to correct and change the virtual image stored in the storage unit 34 when the content is updated, it is only necessary to periodically change the content to make a repeater. .

In addition, as a virtual image, an image showing the name of a specific object (a famous monument, a famous attraction, etc.) corresponding to the marker, or an image in which the sightseeing information or the commentary of the specific object is recorded is used. The display of the display unit 2 can also be used as an image guide for the Ferris wheel. In addition, the virtual image allows it to display the name of the company in front of the building, and can record the name of the company, the name of the product or the name of the brand on the advertising balloon that is floating in the air, and can use it as a so-called digital signage (digital signage, Electronic advertising board).

In addition, the virtual image can also be used as a CG image to display the appearance of the sea, the water, and the ground; or the actual scenery can be used as a night image, such as aurora, lightning, The images of the universe and constellations are made into CG images to create virtual images.

As described above, the Ferris wheel of the first embodiment includes a plurality of nacelles, a photographing unit, a display unit, and a control unit. The camera department is installed in each pod. The composition of the photo studio is used to photograph the scenery outside the pod. The display unit is disposed in each of the nacelles. The control unit is configured to superimpose a virtual image on a specific position of an actual image captured by the photographing unit to generate a composite image. The configuration of the control unit is for displaying the composite image on the display unit.

With such a configuration, the passenger of the nacelle 63 can be given a complex realistic feeling (including an expanded reality and an expanded virtual feeling) using a wide range of fields of view visible from the gondola 63 of the Ferris wheel. Moreover, the nacelle 63 does not continue to move only in the horizontal direction but also in the height direction. Therefore, it is possible to give a composite reality that is not available only to the viewpoint on the ground.

Further, the control unit includes a memory unit, a virtual image deforming means, an image synthesizing means, and an image display means. The memory memorizes the virtual image. The virtual image deformation means is configured to change the size and angle of the virtual image stored in the memory unit according to the position of the pod. The image synthesizing means is for superimposing an image changed by the virtual image deforming means on a specific position of the actual image photographed by the photographing section, thereby generating a composite image. The image display means displays the image generated by the image synthesizing means on the display unit.

In this case, the virtual image can be deformed in accordance with the movement of the nacelle 63. Thereby the composite image is close to the real person.

Further, the Ferris wheel has a position detecting unit and a shooting direction detecting unit. The position detecting unit is configured to detect the position of the photographing unit. The shooting direction detecting unit is configured to detect the photographing direction of the photographing unit. The virtual image deformation means is configured to change the virtual image according to the detection information of the position detecting portion and the detection information of the shooting direction detecting portion.

In this case, the positional calibration of the actual image and the virtual image can be performed relatively accurately.

Further, the control unit further includes a marker recognition means and a position/orientation analysis means. The marker identification means is used to identify a specific object contained in the actual image as a marker. The position/orientation analysis means is configured to analyze the position and posture of the marker recognized by the marker recognition means. The memory unit stores the virtual image in advance in association with the marker. The virtual image warping means changes the virtual image based on the position/posture information of the marker analyzed by the position/posture analysis means. The control unit recognizes the marker by the marker recognition means, that is, acquires a virtual image corresponding to the marker from the memory.

The control unit changes the virtual image acquired from the memory unit via the virtual image deformation means. In other words, the virtual image transformation means changes the virtual image obtained by the control unit.

Further, the control unit generates a composite image by superimposing the changed image on a portion of the marker corresponding to the actual image by image synthesis means. The image display means causes the composite image to be displayed on the display unit.

In this case, the accuracy of the positional calibration of the actual image and the virtual image can be improved.

Further, the photographing unit 1 is provided outside the nacelle 63 and is a camera that can change the photographing direction. The pod 63 further has an operation portion 5 for changing the photographing direction of the camera.

Thereby, the actual image of the viewpoint desired by the passenger of the car 63 can be displayed by superimposing the virtual image on the virtual image. Thus, the passenger can be given a sense of complex reality that utilizes a wider range of fields of view.

Next, the second embodiment will be described with reference to FIG. The present embodiment is substantially the same as the above-described embodiment, and the same portions are denoted by the same reference numerals, and description thereof will be omitted.

The display unit 2 of the Ferris wheel of the present embodiment is provided with the head mounted display device 7, and this point is different from the above embodiment. This head mounted display device 7 is constituted by a head mounted display device 70 (HMD). The head mounted display device 70 is a display that can be worn on the head. When the passenger wears the head mounted display device 70, the display as the display unit 2 covers the front side of the passenger's eyes.

The Ferris wheel of the present embodiment is provided with a coupling portion 71 for connecting the head mounted display device 70 to the operation unit 5. This connecting portion 71 is connected to the control unit 3. When the head mounted display device 70 is connected to the connection portion 71, the image signal sent from the image display means 35 of the control unit 3 is received, and the composite image is displayed on the display unit 2 covering the front of the eye.

In this way, if you set to display the past scenery or the future scenery, you can look at the time-space landscape like a time machine.

Further, the content displayed on the display unit 2 of the head mounted display device 70 can be used to make the passenger feel the depth of field and the stereoscopic effect using the 3D method. In other words, the control unit 3 may be provided with a 3D image forming means for generating an image different from the content seen by the left eye and the content seen by the left eye, and generating the passenger to the display unit 2 The display content is cognizant as stereo. In order to become a Ferris wheel that is more full of presence.

The above description is based on the Ferris wheel of the present invention based on the composite reality sensor of the marker recognition type. However, the Ferris wheel of the present invention may also use the feature points of any image as a substitute marker. The so-called markerless tracking (for example, exemplified by Japanese Laid-Open Patent Publication No. 2007-207251). In this case, the marker identifying means 30 in the first embodiment is not essential.

Further, the virtual image deforming means of the present invention can change the size and angle of the virtual image in accordance with the constant movement of the Ferris wheel as long as the image can be deformed depending on the position of the pod. Therefore, the position/orientation analysis means 32 of the first embodiment is not a configuration necessary for the present invention.
