VIDEO-BASED MARKER-LESS TRACKING SYSTEM IN GAIT ANALYSIS

Alex Ong, Ian Harris Sujae

Abstract


An alternative to the 30 motion marker-based optical camera capture is the Star Tracker 3D, a marker-less video-based tracking system. The aim of our study is to investigate the efficacy of the Star Tracker 3D. A series of gait analysis tests were carried out on ten subjects with a marker and marker-less tracking system simultaneously. The study suggests potential application in gait analysis in the academic classrooms and clinical settings where observations of anatomical motions can provide meaningful feedback.
