Disclosed herein is a 3D model shape transformation apparatus. 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.

3D model shape transformation method and apparatus

Disclosed herein is a motion capture apparatus and method. The motion capture apparatus includes a three-dimensional (3D) appearance reconstruction unit for reconstructing a 3D appearance of an entity using a multi-view image obtained by capturing the entity at a T+1-th frame. A 3D skeleton generation unit generates a 3D skeleton of the T+1-th frame using the 3D appearance and a model of the entity having a motion of a T-th frame. A motion reconstruction unit reconstructs a motion of the T+1-th frame of the model by changing the motion of the model based on the 3D skeleton of the T+1-th frame.

Motion capture apparatus and method

The present invention relates to a method and apparatus for capturing a motion of a dynamic object, and restore appearance information of an object making a dynamic motion and motion information of main joints from multi-viewpoint video images of motion information of a dynamic object such as a human body, making a motion through a motion of a skeletal structure on the basis of the skeletal structure, acquired by using multiple cameras. According to the exemplary embodiments of the present invention, it is possible to restore motion information of the object making a dynamic motion by using only an image sensor for a visible light range and to reproduce a multi-viewpoint image by effectively storing the restored information. Further, it is possible to restore motion information of the dynamic object without attaching a specific marker.
