“…The simplified (not anatomically precise) kinematic model of the human arm without the palm (Fig. 1), developed by Lenarčič and Umek [14] with the aim to represent the reachability of the arm, has six revolute degrees of freedom: two in the sternoclavicular joint, three in the glenohumeral joint and one in the elbow joint.…”

A model-based approach to reconstruction of 3D human arm motion from a monocular image sequence taken under orthographic projection is presented. The reconstruction is divided into two stages. First, a 2D shape model is used to track the arm silhouettes and second-order curves are used to model the arm based on an iteratively reweighted least square method. As a result, 2D stick figures are extracted. In the second stage, the stick figures are backprojected into the scene. 3D postures are reconstructed using the constraints of a 3D kinematic model of the human arm. The motion of the arm is then derived as a transition between the arm postures. Applications of these results are foreseen in the analysis of human motion patterns.

“…The goal of this investigation was to develop a method for monocular tracking of the human arm in 3D without the use of markers. In particular, we were interested if the kinematic model of the human arm that was at our disposal [14] provided enough constraints to do that. We consider the human arm to be a six degree-of-freedom (d.o.f.)…”
