Regardless of the application, SP systems exhibit different random and systematic errors depending on camera specifications, system setup and laboratory environment, which hinders comparing SP data between sessions and across different systems. While many methods have been proposed to quantify and report the errors of SP systems, they are rarely utilized due to their complexity and need for additional equipment. In response, an easy-to-use quality control (QC) check has been designed that can be completed immediately prior to a data collection. This QC check requires minimal training for the operator and no additional equipment. In addition, a custom graphical user interface ensures automatic processing of the errors in an easy-to-read format for immediate interpretation. On initial deployment in a multicentric study, the check (i) proved to be feasible to perform in a short timeframe with minimal burden to the operator, and (ii) quantified the level of random and systematic errors between sessions and systems, ensuring comparability of data in a variety of protocol setups, including repeated measures, longitudinal studies and multicentric studies. 4950 https://doi.org/10.3390/s21248223$xR$3Volltext$534 4950 https://nbn-resolving.org/urn:nbn:de:gbv:8:3-2022-00046-5$xR$3Volltext$534 4961 https://macau.uni-kiel.de/receive/macau_mods_00002396 5051 610 5550 3D Motion Capture 5550 Accuracy 5550 Gait 5550 Human Movement 5550 Humans 5550 Movement 5550 Optoelectronic Stereophotogrammetry 5550 Photogrammetry 5550 Quality control 5550 Quality Control 5550 Spot Check 5550 Systematic Errors
