Abstract

This paper presents a shape and pose estimation method for 3D multi-part objects, the purpose of which is to easily map objects from the real world into virtual environments. In general, complex 3D multi-part objects cause undesired self-occlusion and non-rigid motion. To deal with the problem, we assume the following constraints: – object model is represented in a tree structure consisting of deformable parts. – connected parts are articulated at one point (called “articulation point”). – as a 3D parametric model of the parts, we employ deformable superquadrics (we call DSQ). To estimate the parameters from the sensory data, we use time modelspace gradient method, which reduces the parameter estimation problem into solving a simultaneous linear equation. We have demonstrated that our system works well for multiple-part objects using real image data.
