BEST MODE FOR CARRYING OUT THE INVENTION Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows the overall configuration of a three-dimensional object generation device according to this embodiment.
The three-dimensional object generation device according to the present embodiment includes a reflected light image input unit 1, a color image input unit 2, a reflected light image division unit 3, a three-dimensional information acquisition unit 4, a reflection characteristic information storage unit 5,
A three-dimensional information storage unit 6, an attribute information storage unit 7, and an attribute information generation unit 8 are provided.

The reflected light image input section 1 includes a light emitting source 11 and
Imaging optical system 12, image sensor 13, and control unit 14
Composed of and. The light emitting source 11 is a light source that emits monochromatic light such as near infrared light, and illuminates the target object B. The light emitting light source 11 is alternately turned on and off by the control unit 14. As a technique previously filed by the inventor, there is known a technique of irradiating an object with light such as near-infrared light and acquiring the reflected light as an image to easily and rapidly acquire a three-dimensional shape. (JP-A-10-1
77449). Since the intensity of the reflected light has a correlation with the position (distance) of the object, a pseudo three-dimensional image can be acquired by using the reflected light image.

In the present embodiment, the reflection characteristic of the object is stored in the reflection characteristic information storage unit 5, and by utilizing this, more accurate three-dimensional information is acquired. Even with the same material, the reflectance is low in the black portion and high in the white portion. Further, even if the same substance and the same color are used, the amount of reflected light differs depending on whether the object surface is a rough surface or a mirror surface. Therefore, the reflection characteristic is acquired in advance, and based on the reflected light image, 3
By using it when acquiring the dimensional information, it is possible to acquire more accurate three-dimensional information.

The target object B of this embodiment is made of clay here. As will be described later, various shapes are made of clay, the reflected light image and the color image are imaged, and appropriate processing is performed, so that the shape of the clay is captured as a three-dimensional object in the computer. After being captured as a three-dimensional object in a computer, it is possible to perform creative work such as placing it in a three-dimensional virtual space or moving it. Children often play clay, but make and destroy various shapes (animals, cars, etc.) and make and destroy them. This alone is very effective for children's education, but by combining this with the world of games, there is a possibility of expanding a richer world. For example, if the made clay (vehicles, dinosaurs, animals, dolls, etc.) is made into a three-dimensional shape and brought into the game world, clay play itself is a very effective educational play for children. Can be developed into a realistic play.

Conventionally, there is a concern that a video game or the like may be immersive in a virtual space and may be confused with the real world, which is not good for education. However, according to the device of the present embodiment, since it is possible to touch clay as a real existence with a hand and actually form something, the real world and the virtual world are appropriately fused, and the child's Digital toys are provided that are extremely effective in increasing creativity.

In this embodiment, it is assumed that the target object B is made of clay of different colors which are predetermined for each of its constituent elements. For example, in the case of a bear doll as shown in FIG. 1, the head part b1 is red clay, the body part b2 is yellow clay, the arm parts b3 are blue clay, and the foot parts b4 are green clay. is there. This is because, as will be described later, it is necessary to generate a moving three-dimensional object or paste a texture.

The image pickup optical system 12 produces an image of the target object B illuminated by the near infrared light from the light emitting light source 11 and other light (sunlight, light of a fluorescent lamp in the room, etc.). It is for forming an image on.

The color image input section 2 is composed of an image pickup optical system 12 and an image sensor 13, and the light from a source other than the light emission source 11 (for example, indoor lighting or sunlight) causes the target object B to be reflected. It is for taking a color image. As shown in FIG. 2, the image sensor 13 of FIG. 1 has a form in which color image acquisition pixels 13c and reflected light image acquisition pixels 13r (indicated by diagonal lines in the drawing) are alternately arranged. For example, as shown in FIG. 2, the color image acquisition pixels 13c are arranged in odd rows and the reflected light image acquisition pixels 13r are arranged in even rows. Thereby, the reflected light image and the color image can be acquired.

The image sensor 13 is controlled by the controller 14. The control unit 14 includes, for example, as shown in FIG. 2, a vertical selection unit 14a, a horizontal selection unit 14b, and a storage unit S.
t, the analog signal processing unit 14c, the A / D conversion unit 14d,
The image processing unit 14e and the control circuit 14f are provided. The vertical selection unit 14a and the horizontal selection unit 14b are for selecting a pixel position and taking out the output accumulated in the pixel. The storage unit St is a unit that temporarily holds the charges extracted from the selected pixel for processing in the analog signal processing unit 14d described later.

According to the control signal of the control circuit 11, the vertical selection section 14a is adapted to select an odd row when the light emitting source 11 is turned off and an even row when emitting light. That is, when the light source 11 emits light, the even-numbered pixels (reflected light image acquisition pixels) capture reflected light images, and when the light source 11 does not emit light, odd-numbered pixels (color image acquisition pixels).
Take a color image with.

The analog signal processing section 14c includes a storage section St.
The charges accumulated in the memory are sequentially read and an analog signal corresponding to the charges is output. This analog signal is converted into a digital value by the A / D conversion unit 14d and subjected to predetermined image processing by the image processing unit 14e, thereby outputting a color image and a reflected light image. Although the reflected light image input unit 1 and the color image input unit 2 share the photographing optical system 12 and the image sensor 13 in FIG. 1, only the photographing optical system 12 is shared and the image sensor is 2 separately
You may provide one.

Returning to FIG. 1, the reflected light image dividing section 3 divides the reflected light image based on the color information contained in the color image obtained from the color image acquisition pixels from the image sensor 13. is there. FIG. 3 is a conceptual diagram illustrating the function of the reflected light image division unit 3. The color image CI and the reflected light image RI of the target object B are input from the image sensor 13. The bear doll as the target object B has a different color for each component, as described above. The reflected light image division unit 3 divides the reflected light image RI into each component based on the color information included in the color image CI. In the example of the bear doll shown in FIG. 3, the reflected light image RI includes a portion 1 corresponding to the head portion b1, a portion 2 corresponding to the body portion b2, a portion 3 and a portion 3 ′ corresponding to the arm portion b3, and a foot portion. It is divided into a part 4 and a part 4'corresponding to b4. When the target object B is made of one monochromatic material, the reflected light image division unit 3 does not function, but since the monochromatic target object B can be divided into constituent elements, A method of dividing the target object B by a known method such as template matching may also be used in a supplementary manner.

The three-dimensional information acquisition unit 4 uses the reflection characteristic information stored in the reflection characteristic information storage unit 5 to reflect the reflected light image 21.
To obtain the three-dimensional shape information of the target object B. That is, the reflection characteristic information storage unit 5 stores the reflection characteristic of the material of the target object B. Here, since the target object B is composed of red, blue, yellow, and green clay as described above, the reflection characteristics of these four color clays are stored in the reflection characteristic information storage unit 5. The three-dimensional information acquisition unit 4 divides the reflected light image 21 into the divided portions 1 based on the reflection characteristic information of the clay of each color read from the reflection characteristic information storage unit 5.
Analysis of every 2, 3, 3 ', 4, 4', 3 of the target object B
Acquire dimension information. In the reflected light image 21, as shown in FIG. 3, the dot density represents the three-dimensional shape of the target object B, but due to the difference in reflectance between the constituent elements, the reflected light image 21 accurately represents the three-dimensional shape. is not. By using this reflection characteristic information, accurate three-dimensional information can be acquired.

The three-dimensional information storage section 6 is a section for storing the three-dimensional shape information of the target object B acquired by the three-dimensional information acquisition section 4. The attribute information storage unit 7 is a unit that stores the color information regarding the color of the component of the target object B and the attribute information regarding the attribute of the component in association with each other. For example,
In the bear doll shown in Fig. 3, the red part is the animal's head,
The color and the types of its constituent elements can be stored as attribute information such that the yellow part is the body of the animal. As another example of the attribute information, it is also possible to include motion information indicating what kind of movement an object constituted by that color can move. For example, if it is a head, it can include motion information such that the lower side moves about the center of rotation, and if it is a foot, its root is the center of rotation and it can be bent near the center. Operation information such as can be included.

It is also possible to include the physical characteristics of the constituent elements in the attribute information. For example, the elastic characteristics and specific gravities of the constituent elements are included as attribute information, and the target object B is caused to move according to its characteristics (eg, a round object rolls, a square object does not roll, etc.), or It is possible to include attribute information such that it will melt out after a while. It is also possible to store attribute information that a sound effect is generated for a specific component, and to make a motion such that a sound effect is generated each time this component moves.

The attribute information adding section 8 reads out the attribute information corresponding to the color information of each of the portions 1, 2, 3, 3 ', 4 and 4'from the above attribute information, and reads the attribute information thus read out. To each part 1, 2, 3, 3 ', 4, 4'. This completes the generation of the three-dimensional object. That is, each part 1, 2, 3, 3 ', 4, 4'is given an accurate three-dimensional shape by the three-dimensional information acquisition unit 4, and the attribute information storage unit 7 causes the attribute information of each part. Is given. Each part 1, 2, 3, 3 in the attribute information storage unit 7
If the motion information of ', 4, 4'is stored,
The attribute information addition unit functions as a motion information generation unit that adds motion information to each component. For example, the three-dimensional object can be moved in a video game or the like according to appropriate instruction information, or can be controlled so as to move by itself under some protocol.

Morphing for three-dimensional objects (image processing technology for smoothly changing the shape of an object drawn in a digital image. For details, see "Introduction to Morphing" (Scott Anderson, translated by Kei Sakai, published by Kaibundou Publishing)). Also when applying, it is possible to change the morphing method by this attribute information. For example, the influence of gravity and the softness / hardness of an object can be reflected in morphing.

In the above description, the case in which the material of the target object is clay has been illustrated, but the present invention is not limited to this, and examples thereof include styrofoam, cardboard paper, and building blocks commercially available from toy makers. , Any material can be used. In the case of these materials as well, by storing the reflection characteristics and the like of the materials in the reflection characteristic information storage unit 5 in advance, it is possible to obtain the same effect as that of the above-mentioned example of clay.

Further, the user can edit the contents of the attribute information storage section 7. For example, when the color information of the arm portion is stored as blue, this color can be edited to be changed to another color. Regarding the information regarding the foot portion, when only the information that the bending is performed near the middle is stored as the attribute information, the attribute information that the bending is also performed near the ankle can be added.

Further, a plurality of three-dimensional information is stored for one target object, and the attribute information generating unit 8 generates three-dimensional information in an intermediate state of the plurality of three-dimensional information by data interpolation to make a smooth change. To be expressed.
The information on the intermediate state may be stored in the three-dimensional information storage unit 6 and reproduced in a 3D movie in the order of change.
Further, it may be generated in response to a request and then may be appropriately displayed.

The apparatus is placed in front of the user, and the user processes the block-shaped clay to form a desired shape in front of the apparatus as shown in FIG. Therefore, the clay work may be always imaged. Thereby, the shape of the clay work on the way of the completion of the target object B can be acquired.
In order to prevent the user's hand or the like from being input, the user may sew the space between the rested hands to capture an image.

By continuously changing the series of three-dimensional shapes acquired in this way as it is, it is easy to create an animation in which the shape emerges from an empty state and the target object B is formed. Can be created.

Also in this embodiment, the reflected light image input section 1 and the color image input section 2 similar to those in FIG. 1 are used, but these are omitted in FIG.

In this embodiment, a texture information extraction unit 21, a texture information storage unit 22, and a texture pasting unit 23 are provided as a configuration for adding color or texture to a three-dimensional object. Thereby, for example, another stuffed animal pattern (for example, a giraffe stuffed animal pattern) can be pasted on the created three-dimensional object as an imaginary animal shape. The texture information extraction unit 21 extracts the texture information of the target object B from the color image information and the reflected light image information from the image sensor 13. Although the image around the target object B including the background is also shown in the color image, the texture information of the target object B can be easily extracted by using the reflected light image information.

The extracted texture information is temporarily stored in the texture information storage unit 22. The texture pasting unit 23 is for assigning the texture information stored in the texture information storage unit 22 to the three-dimensional object to which the attribute information is assigned by the attribute information assigning unit 8 and converting it into a textured object. . As shown in FIG. 1, the target object B in the present embodiment is basically assumed that each constituent element is made of a different material, and therefore the texture is different for each constituent element.

It is possible to paste the extracted texture as it is to the three-dimensional object by the texture pasting unit 23. However, for example, when the texture information of A is extracted, this texture a1 is
If the texture information is extracted, the texture b1 may be pasted, and a separate texture may be pasted. It is also possible to present a plurality of textures on a monitor screen or the like so that the user can select a desired one. Further, when a plurality of pieces of texture information are extracted, only the texture information having the largest area ratio in the target object B may be extracted and the texture may be attached to the entire target object B.

The embodiment will be described with reference to FIG. The three-dimensional object generation device according to the present embodiment uses the 3
The dimensional object is made to be processed by the user with the virtual tool 24. For example, the display unit 26
The three-dimensional object generated as shown in FIG. 6 is displayed, and the user is caused to have the virtual tool 24 and positioned in front of the photographing optical system 12. The virtual tool 24 is, for example, a chisel as shown in FIG. 6, and by making the pattern portion and the blade portion have different colors and storing their reflection characteristics in the reflection characteristic information storage unit 5, The shape information of the virtual tool 24 is grasped by the dimension information acquisition unit 4. The position of the virtual tool 24 on the display unit 25 is changed by the display control unit 26 based on the acquired position information of the cutting edge of the virtual tool 24.

When the user moves the hand holding the virtual tool 24, the position of the graphic showing the virtual tool 24 on the display unit changes, and thereby the generated three-dimensional object is processed. It is possible to process a three-dimensional object on the screen with the same feeling as when actually processing a target object B with a chisel or the like.

The input unit 31 is provided. The range finder typically scans the target object B with a laser spot light or a laser slit light, and obtains it from the light receiving position of the reflected light by the principle of triangulation. Since the range image information itself includes three-dimensional information, the present embodiment does not require the three-dimensional information acquisition unit 4 and the reflection characteristic information storage unit 5 as in the first to fifth embodiments.

Further, the three-dimensional object generation device of this embodiment is provided with a three-dimensional information extraction and division unit 33. The three-dimensional information extracting / dividing unit 33 extracts three-dimensional information from the distance image information, and extracts the three-dimensional information from the three-dimensional information based on the color information obtained from the color image input unit 2.
