摘要：
In this paper, a binocular 3-D computer vision measurement system is used to measure the relative displacement for the greater and lesser tuberosities in the shoulder prosthesis. The basic principles of binocular optical measurement are introduced in detail, and the loading apparatus is designed for external rotation and anteflexion of the shoulder prosthesis. Both the motion of external rotation and anteflexion of the shoulder are measured, and the corresponding displacement values for the greater and lesser tuberosities are extracted. These results will play an important role in evaluating the stability of humeral tuberosity in the shoulder prosthesis.
