However, there are many high-loaded tasks sometimes still need to be performed manually. This could put the workers under high risks of musculoskeletal injuries. In order to indentify the potential injury when workers perform various jobs, their working postures need to be collected and analyzed. Tranditionally, a complex and expensive motion tracking are used to collect these movement data. Recently, many researchers proposed the use of low cost RGB-D camera as an alternative. But not many researchers evaluated the capability of RGB-D cameras objectively before using it. In this study, we evaluate the accuracy of the RGB-D camera when it was used to track several static postures. The data from traditional motion tracking system were compared to the data outputs from the RGB-D camera. A total of 12static standing poustures and 9 static sitting postures were evaluated. The effect of RGB-D camera viewing angles (0°、45°、90°) are also examined.
