EARS: Toward Fast Analysis of 3D Human Scans

We present the Enhanced Anthropometric  Rating System (EARS), an integrated collection of tunable semi-automatic procedures to compute, visualize, and evaluate the geometric information of a 3D human body scan. To the best of our knowledge, EARS is the first complete system dedicated to fast evaluation and analysis of the quality of a human scan data. EARS is able to detect and remedy scan flaws, perform fast anatomically guided segmentation, analyze the posture of the scanned subject, evaluate the quality of the triangle surface, and provide real-time feedback on the quality of a human body scan mesh. We have tested EARS on a set of 100 female and 100 male subjects randomly drawn from the CEASER database. The average run time on a model is less than 30 seconds. EARS is robust on a test data set of unusual poses. EARS presents intuitive GUI and can also be run in command mode. It is compatible with the Cyberware Inc. CyScan software and will be employed by the US Army during the upcoming large scan anthropometric survey.
