摘要： A virtual reality embodying system uses 2D images and HDRI data taken of a target object through a camera to embody virtual reality. A modeling unit compares the 2D image's coordinate with a real coordinate to calculate a transform matrix, calculates a vanishing point of a reference vector, uses the vanishing point to calculate a camera matrix, uses the camera matrix and the transform matrix to calculate a rotation matrix and a translation matrix, and uses the rotation matrix and the translation matrix to model the 2D image into a virtual model. A rendering unit uses the HDRI data as texture to render the virtual model, and embodies the HDRI into an extended VRML node to apply the virtual model to the VRML environment.

The 3D model shape transformation apparatus includes a camera unit, a shape restoration unit, a skeleton structure generation unit, and a skeleton transformation unit. The camera unit obtains a plurality of 2D images in a single frame by capturing the shape of an object. The shape restoration unit generates a 3D volume model by restoring the shape of the object based on the plurality of 2D images. The skeleton structure generation unit generates the skeleton structure of the 3D volume model. The skeleton transformation unit transforms the size and posture of the 3D volume model into those of a template model by matching the skeleton structure of the template model with the skeleton structure of the 3D volume model.
