A dynamic capture 3D data processing method

Abstract

The invention discloses a processing method for dynamically capturing 3D data and a 3D model thereof. The method comprises the following steps: creating a 3D model of a role; sequentially establishing multiple bones with specific hierarchical structures, and binding the bones with corresponding joints of the 3D model of the role; obtaining body movement data of a motionactor through a dynamic capturing system; introducing the body movement data into the bones through preset software and adjusting a bone movement curve; under the drive of the bones, the 3D model executes corresponding actions along the bone movement curve; and the step of adjusting the bone movement curve specifically comprises: introducing spatial displacement data in the body movement data into displacement bones extending out from the hip bones. The method is used for effectively reducing the errors of action displacement to make the animation of the 3D model be more real and reduce the subsequent displacement modification of an animator, so as to improve the animation making quality and speed of the 3D model.

Description

technical field [0001] The invention relates to the field of 3D model animation construction, in particular to a dynamic capture 3D data processing method and a 3D model thereof. Background technique [0002] In previous 3D film and television productions, animations were usually keyed by an animator (that is, animation key frames were generated). However, due to the limitation of manual operation, a good animator can KEY the animation with limited time and speed, and it is relatively difficult for an animator to KEY to the actions performed by real people compared with the fidelity of real people's actions. [0003] With the development of the times, motion capture technology has emerged. That is to say, it dynamically captures and collects the body movements of action actors, and the collected body movements can be quickly used in film and television production. The animation data collected by the existing dynamic capture technology (that is, the displacement and rotatio...
