Abstract
The present disclosure describes systems and techniques relating to generating three dimensional (3D) models from range sensor data. According to an aspect, 3D point clouds are captured using a 3D camera, where each of the 3D point clouds corresponds to a different relative position of the 3D camera with respect to a body. One of the 3D point clouds can be set as a reference point cloud, and transforms can be determined for coordinates of the other captured 3D point clouds to transform these to coordinates of the reference point cloud. The body represented in the reference point cloud can be segmented into body parts corresponding to elements of a 3D part-based volumetric model including cylindrical representations, and a segmented representation of the physical object of interest can be generated in accordance with the 3D part-based volumetric model, while taking localized articulated motion into account.
