Title
(EN) BODY SHAPE AND POSE ESTIMATION VIA VOLUMETRIC REGRESSOR FOR RAW THREE DIMENSIONAL SCAN MODELS
Abstract
(EN)

An electronic device for object rigging includes a processor. The processor is configured to obtain a three-dimensional (3D) scan of an object. The processor is also configured to identify 3D coordinates associated with joints of the 3D scan. The processor is further configured to identify parameters associated with fitting a 3D parametric body model to the 3D scan based on the 3D coordinates of the joints. Additionally, the processor is configured to modify the parameters to reduce 3D joint errors between the 3D coordinates associated with the joints on the 3D scan and the 3D parametric body model. The processor is also configured to generate a rigged 3D scan based on the modified parameters, for performing an animated motion.
