Investigating the RGB-D camera tracking accuracy in different carrying tasks

The musculoskeletal disorder is still one of the significant concerns among all work-related injuries. A great deal of research efforts had been made in developing tools that can be used in practical working environments for real time assessment of manual workloads. To perform those evaluations, the working posture analysis is required. Recently, the RGB-D camera has been considered by researchers as a potential device to record and track the human motion. In this study, the traditional motion tracking system was used as the reference to calculate the joint coordination errors while using RGB-D camera to generate the movement data in three different carrying task ranges: 0°-45°, 45°-90°, 90°-135°. The result showed that the 0°-45° range yielded the lowest error. The highest error was observed in the range 90°-135°. The lower body resulted a lower average error in comparison to the upper body.
