Posture Reconstruction: Full-Body Interaction

This lecture covers the background on full-body motion capture, posture reconstruction techniques such as Analytic IK and Jacobian-based IK, collision avoidance, and examples of full-body interaction. It explains the process of system calibration, camera registration, and full-body tracking. The comparison of Analytic IK and Jacobian-based IK methods is discussed, along with their advantages and drawbacks. The concept of priority levels in Jacobian-based IK for handling redundancy and conflicting tasks is explored, with demonstrations on interactive goal movement. The lecture also presents a low-cost Analytic solution for full-body scale motion capture and the use of hybrid techniques like CCD and FABRIK. Various concepts like forward kinematics, inverse kinematics, and posture variation are explained in the context of full-body motion capture.
