Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to articles, people, animals,
An imaging apparatus for acquiring two-dimensional image data and various parameters serving as a basis for reconstructing and displaying a three-dimensional object such as a plant as a three-dimensional image on a computer based on the two-dimensional image of the three-dimensional object; The present invention relates to an imaging method.

[0002]

2. Description of the Related Art At present, a system for generating a three-dimensional image of a subject from a plurality of two-dimensional images obtained by imaging a three-dimensional object has been developed. For example, JP-A-9-331440 discloses a technique for reconstructing a three-dimensional image based on a two-dimensional image. In order to generate a three-dimensional image of a three-dimensional object as a subject, three-dimensional coordinates of the three-dimensional object are required. The three-dimensional coordinates can be obtained from the difference in the appearance of the corresponding points of the subject in the plurality of two-dimensional images. However, in order to obtain the three-dimensional coordinates, it is necessary to know “under what imaging conditions the two-dimensional images are captured”. That is,
Information such as the camera position at the time of capturing each image and the camera settings at the time of capturing is required. In the conventional method, it is necessary to estimate imaging conditions such as a camera position, an angle, and a focal length.Therefore, at the time of imaging, a subject and an object having a known shape are placed, and from the appearance of the object having the known shape. , Camera position, angle, focal length, etc. (see FIG. 10).

Here, an example of a conventional method from imaging to data creation will be described. A: From imaging to camera position calculation (1) A subject is set in a pedestal or a checkered screen provided with an object of a known shape. (2) A plurality of photographs are taken of an object and a subject having a known shape together at different angles. (3) Specify a plurality of calibration points (points for correction) of the pedestal or checkered screen in the photographic image on the computer. (4) The principal point (center) position of the camera lens is estimated by calculation from a plurality of photographs on the image processing software.

B: Calculation of three-dimensional position of subject and creation of polygon (1) A plurality of reference points (points corresponding to each photographic image) in a plurality of photographic images on a computer are designated. (2) The three-dimensional shape of the subject is calculated on the image processing software. (3) Select three reference points, cover the calculated three-dimensional surface with a triangular surface, and specify an area of photographic image data (two-dimensional image data) to be pasted on the surface (rendering) Area specification). (4) Perform rendering on image processing software to generate a three-dimensional image. In the conventional method, a three-dimensional image is obtained from a two-dimensional image as described above.

[0005]

However, such a method has the following problems. 1) There are restrictions on lighting (lighting). This is because, when the three-dimensional image restored by the above method is rotated, the highlight portion of the subject moves, which causes problems such as a poor three-dimensional appearance and difficulty in viewing. 2) It is necessary to estimate the camera position and the like. If an image is taken while moving the position of the camera, the distance between the subject and the principal point of the lens, the angle between the subject and the principal point, and the like change, and it is necessary to estimate these. Therefore, it takes an estimated time to perform the restoration processing on the three-dimensional image, and the processing takes time. 3) The image cannot be captured in the background color. In the case of a mirror-finished metal product or the like, an object of a known shape arranged together appears on the surface of the metal product. Therefore, when combining with a different background, the restored three-dimensional image of the subject appears to float in the air.

[0006] The present invention has been made in view of the above points, and can obtain two-dimensional image data for generating a more accurate three-dimensional image, and can generate a three-dimensional image from the two-dimensional image. It is an object of the present invention to provide an image pickup apparatus and an image pickup method that do not require estimating a predetermined parameter such as a camera position required for the camera.

The imaging apparatus according to the present embodiment has a rotating table 2 on which a three-dimensional object 1 as a subject is arranged and rotates, and a predetermined angle (for example, from the center of the rotating table 2) with respect to the table surface.
0 degree), a rail (track) 3 installed at a position extended in a direction forming an angle, a lighting fixture 4 installed on a rotary table 2, an imaging camera 5 installed on the rail 3, and an imaging camera The storage device 6 stores an image signal (two-dimensional image data) output from the camera 5 and the like, and a computer 7 for inputting data such as parameters described later and storing the parameters in the storage device 6.

Of course, the imaging camera 5 and the rail 3
The rotary table 2 is configured so that the positional relationship between the imaging camera 5 and the rotary table 2 can be accurately measured. Note that the imaging camera 5 may be a single-lens reflex camera in which the angle of the generally used imaging surface and the position and angle of the camera lens unit are known in advance, but the imaging surface (film, CC,
D) and the position and angle of the camera lens unit are variable, and the tilt angle, swing angle, and shift amount of each can be specified. The rail 3 allows the imaging camera 5 to move on the rail 3.

The storage device 6 includes a nonvolatile recording medium such as a floppy disk (FD), a hard disk, and a magneto-optical disk. Further, it is assumed that an input device, a display device, and the like are connected as peripheral devices to the computer 7. Here, the input device refers to an input device such as a keyboard and a mouse. A display device is a CRT (Cat
H.R. tube or liquid crystal display device.

Hereinafter, parameters required for generating a three-dimensional image from a two-dimensional image will be described. Note that parameters marked with “*” are essential, and parameters marked with “•” are not necessarily required. Also,
The following parameters are also required in the imaging devices according to the second to fourth embodiments described below.

First, as parameters (three-dimensional spatial coordinates) indicating the positional relationship between the subject and the imaging camera 5, an angle between the subject and the principal point (center) of the lens (elevation angle / f (depression) angle) * Distance from the subject to the principal point of the lens * Rotation angle of the subject (essential when using the rotary table 2 in addition to the present embodiment)-Distance from the center of the rotary table 2 to the principal point of the lens (the rotary table) 2).

Further, as parameters inside the imaging camera 5, there are: * focal length of the lens * tilt angle, swing angle, shift amount of the imaging surface (film, CCD) * lens aberration * subject size (The length may be from a predetermined reference point to another reference point.)-There is a tilt angle (tilt angle, swing angle, shift amount) of the camera lens unit.

All of these parameters can be accurately measured and acquired at the time of imaging by adopting the above-described apparatus configuration. Further, acquisition of data serving as a basis for these parameters may be taken into the computer 7 from a displacement sensor or the like attached to a predetermined portion via an interface built in the computer 7 to calculate each parameter. . FIG. 2 shows an example of the data flow in this case. Between the imaging camera 5 and the computer 7,

Using the above parameters and a plurality of two-dimensional images of the subject at the time of imaging using the imaging apparatus according to the present embodiment and the second to fourth embodiments, a three-dimensional image of the three-dimensional object 1 as the subject is electronically calculated. Which can be generated above.

The above parameters (hereinafter, referred to as parameter sets) acquired under one imaging condition and two-dimensional image data obtained by imaging under the same condition are stored in the computer 7. .
