Abstract

PROBLEM TO BE SOLVED: To make automatically generable a series of three-dimensional(3D) human body model groups having the personality of each of individuals while having a character uniform as a whole through a simple input procedure. SOLUTION: The size of a human body part to be a characteristic person feature amount is extracted only from plural picked-up photographs and a deformation parameter is fond while referring to the standard size of a human body on the basis of this extracted size. Then, by deforming an applied arbitrary basic model, the 3D human body model reflected with the morphological features of each of individuals is generated while keeping the character uniform as a whole.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a generating device for automatically generating a three-dimensional human body model having individual morphological characteristics without using a complicated measuring device.

[0002]

2. Description of the Related Art In a virtual space constructed on a game or a network which has been developing in recent years, a participant projects himself on the virtual space using a human body model called an avatar, which is an alter ego of the participant. Often. Currently, these human body models are often prepared in advance in the virtual space.However, in order to request self-expression and prevent problems in the virtual space, models with the user's own form are used. There is a potential need to use it.

[0003] Also, there is an extremely high demand for owning a stuffed toy or a doll with the morphological characteristics of one's own or a close relative.

[0004] However, since these human models are conventionally created on a computer using three-dimensional modeling software or the like, they can only be realized by designers with particularly excellent skills. It is difficult for consumers to easily obtain a desired model.

In order to solve this problem, a method of acquiring a human body shape using an active three-dimensional measurement method and acquiring a human body model has been proposed. However, there has been a problem that the measuring device is expensive.

[0006] Further, in the conventionally proposed method, a virtual space manager or a model supplier defines a certain basic trait and reflects the personal characteristics of a user or a purchaser on this basis. There is a problem that it is very difficult to generate a series of three-dimensional human body models having the individuality of each individual while maintaining a sense of unity as a whole.

SUMMARY OF THE INVENTION The present invention has been proposed in order to solve the above-mentioned problems. Individual features are extracted by a simple method without imposing a load on a user. It is an object of the present invention to provide a device that generates a series of three-dimensional human body models having individual characteristics of each individual while having a certain unified trait based on the characteristics.

[0008]

According to the present invention, in order to most easily acquire the morphological characteristics of the human body, it is sufficient to have only a plurality of images of characteristic parts such as the whole body or the head. Focusing on the fact, the image processing technology is applied only from these, and the morphological feature amount of the individual is easily extracted without imposing a load on the user.

Also, in the present invention, the extracted morphological feature is given as a deformation parameter of the basic model to reflect individual characteristics. It is possible to generate a three-dimensional human body model group.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention has been realized simply by extracting morphological features of a human body from a plurality of photographs using an image processing technique and providing the basic models with deformation parameters.

[0011]

FIG. 1 is a view of an embodiment of the apparatus according to the present invention, wherein 1 is an imaging apparatus, 2 is an arithmetic processing apparatus, and 3 is a cutting apparatus.

FIG. 2 is an explanatory view of the process of generating a three-dimensional human body model in the apparatus of the present invention, wherein 4 is a captured image, 5 is a given basic model, and 6 is a generated three-dimensional human body model. .

When a user stands upright on a predetermined position of the apparatus of the present invention, the apparatus of the present invention takes a plurality of necessary photographs including a whole body image of the user. However, the user does not necessarily need to stand upright, and may sit on a chair or the like or give a desired pose. In addition, the user may input a photograph independently taken through an image input device such as a scanner or through an electronic medium or an information network, instead of a photograph taken by a specific image pickup device.

The arithmetic processing unit performs image processing such as background removal, contour line tracing, and mapping processing from the given photograph, thereby transforming the basic model given to the device of the present invention in advance. Acquire the morphological feature of the user. At this time, any basic model can be given, but it is necessary to have basic traits of the human body. In particular, it is preferable that the joint structure be defined by MPEG-4 w2229 or VRML H-ANIM 2.0, which clearly defines the joint structure. In addition, the basic size of each part of the basic model before deformation and the standard human body size for each part need to be clearly given. However, these sizes do not necessarily need to be given in an absolute unit system, but may be given as values relative to the distance in a captured image or the size of a certain part.

Subsequently, the arithmetic processing unit refers to the standard human body size obtained in advance, converts the acquired morphological feature values into deformation parameters of the basic model, and applies the parameters to the basic model to apply the three-dimensional human model. Generate The generated three-dimensional model may be realized as a three-dimensional model having a substance using a cutting device or the like, or as a three-dimensional model represented by three-dimensional computer graphics in a virtual space, an electronic medium or an information network. May be given to the user via

[0016]

As described above, the automatic human body copy model creation apparatus of the present invention automatically generates a three-dimensional human body model reflecting the morphological characteristics of the user by an extremely simple input of only photographing. I can do it. In addition, by applying the acquired morphological personal features as deformation parameters to the basic model and adopting a method of generating a human body model, a series of solids with individuality of each solid is maintained while maintaining a sense of unity as a whole. It is possible to have the convenience of generating a human body model group.
