Trochlear surface reconstruction and evaluation based on laser scanner acquisition

The purpose of this study is to investigate the accuracy, reproducibility and validation of linear measurements on digital reconstruction of the trochlear articular surface. Surface reconstruction is produced by a laser scanner acquisition pipeline that preserves rough data. Arc and chord measurements between chosen landmarks on physical specimens are simulated by geodesic path length evaluation on the corresponding digital models. The osteological specimens are issued from an archaeological series emerging from the “Soeurs Grises”´s cemetery (medieval sample, XV-XVIII century) located in Beauvais (Oise, France).
