副撮像物体２は、なんらかのキャラクターに似せて作られたぬいぐるみである。副撮像物体２の予め定められた特定位置（例えば、関節位置）には、光を反射する反射シートを貼った球状のマーカー２ａが取り付けられている。マーカー２ａは、キャラクターの予め定められた特定位置（例えば、関節位置）それぞれに対応付けられている。そして、副撮像物体２は、被写体７（例えば人物）の膝上等に置かれ、被写体７と一緒に撮影される。   The sub-imaging object 2 is a stuffed toy that resembles some character. At a predetermined specific position (for example, joint position) of the sub-imaging object 2, a spherical marker 2a with a reflection sheet that reflects light is attached. The marker 2a is associated with each predetermined specific position (for example, joint position) of the character. The sub-imaging object 2 is placed on the knee of the subject 7 (for example, a person) and photographed together with the subject 7.

撮影装置３は、被写体７と副撮像物体２とを一緒に撮影する。撮影装置３としては、例えば、撮影時に被写体７の周囲を囲むように配置された複数（例えば、２０台）のＣＣＤカメラを採用できる。そして、撮影装置３は、撮影結果をコンピュータ５に出力する。なお、図面の簡単化のため、図１（ａ）では、一部の撮影装置３の図示を省略し、図１（ｂ）では、撮影装置３とコンピュータ５とを接続するいくつかの信号線の図示を省略した。   The photographing device 3 photographs the subject 7 and the sub imaging object 2 together. As the imaging device 3, for example, a plurality of (for example, 20) CCD cameras arranged so as to surround the periphery of the subject 7 at the time of imaging can be employed. Then, the photographing device 3 outputs the photographing result to the computer 5. For simplification of the drawing, some of the imaging devices 3 are not shown in FIG. 1A, and some signal lines connecting the imaging device 3 and the computer 5 are omitted in FIG. Is omitted.

三次元データ記憶部４は、予め定められたキャラクターの三次元データを記憶している。第１実施形態では、副撮像物体２が表す１つのキャラクターを記憶している。
コンピュータ５は、プログラムに従って各種処理を実行する。そして、コンピュータ５は、各種処理を実行することで、撮影装置３で得た撮影画像に基づき、三次元データ作成部５ａと、三次元データ置換部５ｂと、三次元データ表示部５ｃとを実現する。 The three-dimensional data storage unit 4 stores three-dimensional data of a predetermined character. In the first embodiment, one character represented by the sub-imaging object 2 is stored.
The computer 5 executes various processes according to the program. Then, the computer 5 executes various processes to realize a three-dimensional data creation unit 5a, a three-dimensional data replacement unit 5b, and a three-dimensional data display unit 5c based on the photographed image obtained by the photographing device 3. To do.

三次元データ作成部５ａは、撮影装置３で得た撮影画像、つまり、被写体７と副撮像物体２とが一緒に撮影された撮影画像に基づいて、被写体７の三次元データと副撮像物体２の三次元データとを含む撮影画像の三次元データを作成する。三次元データとしては、例えば、三次元形状を表すデータと、三次元形状の各部の色彩を表すデータとを含むものがある。第１実施形態では、三次元データ作成部５ａは、副撮像物体２の三次元データとして、複数のマーカー２ａそれぞれの三次元位置を表すデータを作成する。そして、三次元データ作成部５ａは、作成した三次元データを三次元データ置換部５ｂに出力する。   The three-dimensional data creation unit 5a, based on the photographed image obtained by the photographing device 3, that is, the photographed image obtained by photographing the subject 7 and the sub-imaging object 2 together, the three-dimensional data of the subject 7 and the sub-imaging object 2 3D data of the captured image including the 3D data of Examples of the three-dimensional data include data representing a three-dimensional shape and data representing the color of each part of the three-dimensional shape. In the first embodiment, the three-dimensional data creation unit 5a creates data representing the three-dimensional position of each of the plurality of markers 2a as the three-dimensional data of the sub-imaging object 2. Then, the 3D data creation unit 5a outputs the created 3D data to the 3D data replacement unit 5b.

三次元データ置換部５ｂは、三次元データ作成部５ａで作成した撮影画像の三次元データのうちの、副撮像物体２の三次元データを、三次元データ記憶部４が記憶しているキャラクターの三次元データで置換する。第１実施形態では、三次元データ置換部５ｂは、三次元データ作成部５ａで作成したデータが表す複数のマーカー２ａの三次元位置それぞれにキャラクターの特定位置（関節位置）それぞれが一致するようにポーズが設定されたキャラクターの三次元データによって上記置換を行う。そして、三次元データ置換部５ｂは、置換後の三次元データを三次元データ表示部５ｃと３Ｄプリンタ６とに出力する。
このように、本実施形態では、三次元データ作成部５ａで作成したデータが表す複数のマーカー２ａの三次元位置それぞれにキャラクターの特定位置（関節位置）それぞれが一致するようにポーズが設定されたキャラクターの三次元データによって上記置換を行うため、副撮像物体２にポーズを取らせることで、キャラクターの三次元造形物９のポーズを容易に設定できる。 The three-dimensional data replacement unit 5b stores the three-dimensional data of the sub-imaging object 2 in the three-dimensional data of the captured image created by the three-dimensional data creation unit 5a.

３Ｄプリンタ６は、三次元造形物作成装置１のユーザが３Ｄプリンタ６の動作を開始させる操作を行うと、三次元データ置換部５ｂから出力された置換後の撮影画像の三次元データに基づいて、図２に示すように、被写体７の三次元造形物８とキャラクターの三次元造形物９とを作成する。３Ｄプリンタ６は、被写体７の断面形状とキャラクターの断面形状とをそれぞれ積層して被写体７の三次元造形物８とキャラクターの三次元造形物９とを作成する。積層方法としては、例えば、液状の樹脂に紫外線を照射して硬化させる方法、融解した樹脂を積み重ねる方法、粉末の樹脂に接着剤を吹き付ける方法がある。 The three-dimensional data display unit 5c generates an image of the three-dimensional data after replacement output from the three-dimensional data replacement unit 5b. Then, the three-dimensional data display unit 5c displays the generated image on the display 4d. Thereby, the user can confirm the image of the three-dimensional structure created by the 3D printer 6 by showing the image displayed on the display 4d.
When the user of the three-dimensional structure creation device 1 performs an operation for starting the operation of the 3D printer 6, the 3D printer 6 is based on the three-dimensional data of the photographed image after replacement output from the three-dimensional data replacement unit 5b. As shown in FIG. 2, a three-dimensional structure 8 of the subject 7 and a three-dimensional structure 9 of the character are created. The 3D printer 6 laminates the cross-sectional shape of the subject 7 and the cross-sectional shape of the character, respectively, to create the three-dimensional structure 8 of the subject 7 and the three-dimensional structure 9 of the character. As a lamination method, for example, there are a method of irradiating and curing a liquid resin with ultraviolet rays, a method of stacking molten resins, and a method of spraying an adhesive onto a powdered resin.
