Description

3D Figure Imaging Device

The present invention relates to an imaging device for producing 3D figures, and more particularly, to a 3D figure imaging device adapted to be able to acquire a video image by rotating and photographing an original figure.

Generally, a figure is a 3D (3D) model that reproduces objects (buildings, vehicles, food, etc.), plants, animals, people, celebrities, animation or movie characters, and specific scenes of movies in a scaled down form. It has great value in exhibition and value, can be touched and feels three-dimensional, and its realistic portrayal and transfer ability are so excellent that its use is expanding recently.

Among such figures, a method of making a figure by photographing an original figure (such as a person (family, a friend, a lover), a pet, a favorite object (vehicle, sports equipment, etc.)), which is a target of making the figure, by using a custom-made method, is called a camera shooting method. Production method is known.

A method of manufacturing figures using a camera by the custom-made method as described above will be briefly described.

First, the originals of the figures are photographed by a plurality of cameras installed in a fixed frame in the form of a net in the room. To explain this in more detail, a fixed frame in the form of a mesh is installed to surround the figure around the original figure, and a plurality of cameras (for example, 85 to 95 units) are installed in the fixed frame in the form of a network, The camera photographed the original figure at the same time.

The video images photographed by the plurality of cameras (which are two-dimensional video data as video data) are transmitted to a caption computer, and the caption computer stores the received video images.

The caption computer transmits the stored image image to the 3D modeling processor computer, and the received 3D modeling processor computer generates 3D modeling data based thereon. Finally, the 3D printer outputs and completes the 3D figures based on the 3D modeling data.

However, the method of photographing the original figure according to the prior art as described above had the following problems.

Conventionally, in order to acquire a video image for 3D modeling work, all the cameras had to be installed in a fixed frame in the form of a mesh surrounding the original figure, and thus, a large number of cameras needed to be 85 to 95 were installed. . As such a large number of cameras were required, there was a problem of excessive spending on camera purchase.

And, in order to install a fixed frame in the form of a mesh for installing 85 to 95 cameras so as to surround (circle) the figure, first, a fixed frame in the form of a mesh must be manufactured. Since both require a horizontal frame and a vertical frame, there was a problem that the production cost of the fixed frame of the mesh form for installing the camera takes a lot.

In addition, as described above, there was a problem in that workability for installing about 85 to 95 cameras in a fixed frame of a mesh form was bad.

In other words, in order to install on the fixed frame of the mesh type, the mounting bracket for installing each camera was installed on the mesh fixing frame, and the camera was required to be fixed to the mounting bracket one by one.

In the case of the conventional camera imaging method, since shadows are generated, there is a problem that a correction operation must be performed after shooting.
