A multi-sensors system for human motion measurement: Preliminary setup (original) (raw)

Gait analysis and human joint motion measurement has been studied extensively in the recent past. Common approaches that have been used include using inertial sensors, multi-camera optical and IR tracking systems, X-ray and fluoroscopy based imaging, force sensors, magnetic sensors and bone-fixed pins for measurement. Soft tissue artifacts (STA) are a common source of error in most type of measurements and the standard procedure in gait analysis has been to use a combination of measurement methods for efficient estimation of joint angles and the link poses. However, there are few studies where a multiple number of methods have been compared and the correlation between results from various approaches studied. In this paper, we propose an outline for measurement for human joint motion using a number of sensors that can give complete information relating to the joints. Our proposed experiment assumes a human joint to be a 6 DOF joint between 2 links. We will mount collars on the limbs ...
