DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for easily displaying a large number of two-dimensional images (hereinafter referred to as "object frames") for displaying a three-dimensional image on an image photographing apparatus, particularly a personal computer. The present invention relates to an image capturing device capable of capturing an image.

[0002]

2. Description of the Related Art Conventionally, in order to display a three-dimensional image of an object or the like on a computer, an object frame and a high-speed computer for image-processing the object frame and image processing software have been required.

However, in recent years, the image processing speed has been improved due to the development of personal computers, and a large number of image processing software for high-speed processing has become available. Furthermore, with the development of the Internet etc., three-dimensional images are static,
In addition, the demand for dynamic display has increased, and accordingly, the necessity of photographing equipment for photographing an object frame has also increased.

[0004] It is necessary to photograph such a large number of object frames from various positions and angles and to perform image processing by a computer. (Since this image processing is different from the gist of the present invention, the description is omitted.)

In order to easily photograph the above object frame, a photographing stand as shown in FIG. 7 has been practically used. (Megellan 250 manufactured by Kaidan Incorporated
0)

[0006] In the photographing table of FIG. 7, a control unit 83 is provided on a support 81 attached to the pedestal 6, and an arm 821 is rotatably attached to the control unit 83 by the control unit 83. The arm 821 is provided with an arm 822 at an arbitrary angle using the joint 84, and the arm 822 is provided with the camera 7.
Can be attached.

The arm 821 has a weight 851 for balance adjustment at an end opposite to the end where the arm 822 is attached, and the arm 822 has a weight 852 for balance adjustment at an end opposite to the end where the camera 7 is attached. The arm 821 and the arm 822 are adjusted so as to be balanced depending on the positions of the joint 84 and the camera 7.

The control unit 83 has a motor and gears inside, and controls the rotation of the arm 821 by a computer (not shown).

The pedestal 6 is provided with a plurality of holes for attaching the turntable 5, and the turntable 5 is selected and attached according to the size of the subject. The subject 8 is placed on the attached turntable 5. Camera 7 is arm 822
The subject 8 can be photographed on the turntable 5 while moving along.

An arm 821 is attached to the control unit 83, and an arm 822 to which the camera 7 is attached is attached to the arm 821. When the arm 821 is rotated by an angle instructed by the control of the control unit 83, the camera on the arm 822 is rotated. Reference numeral 7 rotates around the subject 8 in the illustrated direction. Stop the camera at the shooting position and shoot the object frame from the required viewpoint. At the time of photographing, a digital camera or the like which outputs image data convenient for computer processing as digital data is used.

The photographing position of the camera 7 necessary for the computer processing and the rotation angle data of the subject 8 are stored in the storage section of the computer in association with the photographed object frame.

Further, when photographing the data of the subject 8 from various ranges, after rotating the turntable 5 by a predetermined angle, the photographing is performed by the above-described method, and the photographed object frame is associated with the photographed object frame. It is stored together with the coordinate data of the camera 7.

[0013]

However, in the above-mentioned conventional example, the rotation angle can be designated by the control unit, but the arm 821, the joint 84, the arm 82
2. The cameras 7 are fixed to each other with screws (not shown). Therefore, there are many degrees of freedom of the mounting position, and it is difficult to understand the exact positional relationship between the mounting positions.

That is, the turning radius of the camera 7 changes at the position of the joint 84 fixed on the arm 821. Further, the plane on which the camera 7 rotates, that is, the position with respect to the turntable 5 changes with the position of the camera 7 attached to the arm 822.

As described above, it takes time and effort to determine the positions of the joint 84, the camera 7, and the turntable 5 accurately and with good reproducibility to obtain an object frame having accurate coordinate data. It is.

If the coordinate data when the object frame is obtained is inaccurate, the three-dimensional image produced by the computer processing is blurred, causing unnecessary movement in the three-dimensional image. If you try to shoot a blurred image again,
It is difficult to understand the exact positional relationship between each camera, and
And the position reproducibility of the subject 8 is poor,
Also, it is very difficult to obtain an object frame having an accurate coordinate system.

Further, when the arm 821 and the arm 822 become longer or the camera 7 becomes heavier, the weight 851 and the weight 852 for balancing become inevitably heavier.
To support the weight of the camera 7 attached to the arm 822, a large force is applied to the arm 821, the arm 822, the support member 81, and the driving device of the control unit 83. For this purpose, the arm 821, the arm 822 and the support 81 must be made unnecessarily robust.

In addition, a powerful computer and the like for driving these, a control unit, a motor for driving a mechanism in the control unit, and the like are required. As a result, a heavy and long apparatus is required, and the manufacturing cost is high. .

In addition, the viewpoint to be photographed may be photographed from the horizontal direction or from the vertical direction. In addition, the camera may have a considerably heavy photographing camera such as a video camera. Because there are many degrees of freedom mentioned above,
Positioning a heavy camera is a time-consuming and skill-intensive operation.

Further, when the subject 8 is rotated on the turntable 5 for photographing, the angle of the turntable 5 with respect to the camera 7 is not clear because there is no standard for the rotation angle of the turntable 5.
It is difficult to understand the exact positional relationship, and therefore, the reproducibility of the position of the subject 8 with respect to the rotation of the camera 7 is poor, and it is very difficult to obtain an object frame having reproducibility from many viewpoints and having an accurate coordinate system. .

As described above, the method of photographing an object frame using a conventional image photographing device requires skill, reduces workability, and lacks data accuracy.
It is not preferable to obtain data for displaying a three-dimensional image without blur.

[0022]

In FIG. 1, an arc-shaped support 1 is erected on a plane orthogonal to the horizontal plane of a subject 8 and is movable along the arc-shaped support 1, and has a window 33 and a reference line 31 therein. 7 is provided. The movable pedestal 3 can move on the arc-shaped support 1 at a fixed distance from the subject 8. The center of the lens of the camera 7 allows the movable pedestal 3 to move even when the subject is photographed from the vertical and horizontal directions. In order to prevent the movable base 3 from coming off, the movable base 3 is extended by an amount corresponding to the length thereof as described later.

When the radius of the arc-shaped column 1 is large, the column 1 may be formed from a plurality of divided portions in order to simplify manufacturing. FIG. 2 is a side view of the arc-shaped column 1. As shown in FIG. 2, the arc-shaped column 1 is divided into an arc-shaped column 13 having an arc AB length and an arc-shaped column 14 having an arc BC length. Divided into two arcs. For example, two arc-shaped columns having an opening angle of 55 degrees are formed, and these are joined to form one arc-shaped column 1 having an opening angle of 110 degrees. The arc-shaped column 1 is lightweight and strong, has an I-shaped or H-shaped cross section, and has an arc shape with the flange portion as a side surface. The arc-shaped column 1 is adhered to the base 11 by, for example, welding, and stands on the base 11.

For example, as shown in FIG. 2, the opening angle is 110 degrees. That is, it is longer by an amount corresponding to an opening angle of 10 degrees in each of the horizontal and vertical directions. In this case, for example, when the radius of the center of the arc-shaped column 1 is taken as the radius of the arc, if the radius is 1.35 m, the horizontal reference point 112 and the vertical reference point 1
Each is 23.5cm longer than 11

A holder 4 for mounting the camera 7 is provided below the movable pedestal 3 and a camera stopper groove 41 is provided so that the lens of the camera 7 faces the subject when the camera is mounted. In addition, when the camera 7 is mounted on the movable pedestal 3, the center axis of the lens of the camera 7 and the reference line 31 match.

The camera 7 is usually set so that the center of the lens is
Since the tripod mounting hole is provided, when the camera 7 is mounted in the camera stopper groove 41 as described above, the center of the lens coincides with the reference line of the movable base 3. When the rotation center is at the position of the vertical reference point 111 on the arc-shaped support 1 on the movable pedestal 3, the movable pedestal 3 moves so that the center of the movable pedestal 3 coincides with the center of the lens of the camera 7 attached to the movable pedestal 3. , The relationship of the camera 7 is determined in advance, so that the rotation center axis of the turntable 5 also coincides.
