Survey on Modeling of Articulated Objects
Jiayi Liu Manolis Savva Ali Mahdavi-Amiri
3D modeling of articulated objects is a research problem within computer
vision, graphics, and robotics. Its objective is to understand the shape and
motion of the articulated components, represent the geometry and mobility of
object parts, and create realistic models that reflect articulated objects in
the real world. This survey provides a comprehensive overview of the current
state-of-the-art in 3D modeling of articulated objects, with a specific focus
on the task of articulated part perception and articulated object creation
(reconstruction and generation). We systematically review and discuss the
relevant literature from two perspectives: geometry processing and articulation
modeling. Through this survey, we highlight the substantial progress made in
these areas, outline the ongoing challenges, and identify gaps for future
research. Our survey aims to serve as a foundational reference for researchers
and practitioners in computer vision and graphics, offering insights into the
complexities of articulated object modeling.
