Validation of an Outdoor-based Passive Optoelectric Motion Capture System

Abstract

The purpose of this study was to validate the quality of data captured outdoors in full sunlight using a passive optoelectric camera system. A golf swing analysis was performed outdoors and indoors using the same system; the outdoor collection was performed in full sunlight. Golf club rotation (deg) and angular velocity (deg•s-1 ) data were calculated about the X, Y, and Z axes of the golf club for a single male subject. Outdoor and indoor angle and angular velocity data were similar about each of the three primary axes of the club, with r values ≥ 0.970. The highest correlation values were found to exist among the angle data. This study demonstrated that data quality captured with an outdoor system is comparable in quality to data captured indoors.
