Optical motion capture (oMC) operation is based on stereophotogrammetry where the three-dimensional coordinates of points (markers) on an object are produced in two or more photographic images taken from different positions. The HMiLab is equipped with a high-speed 12-camera motion analysis system, powered by Optitrack cameras and Motive:Tracker and Motive:Body software, that accurately track 3-dimensional locations of reflective markers to sub-millimeter accuracy at up to 100 samples per second. Motion capture uses cameras 2-dimensional images, combined to create a 3-dimensional approximation of where the object actually is located. This concept is the corner stone of labs studying human motion.
Wearable motion capture (wMC) relies on acceleration and rotational velocity measurements from miniature wearable triaxial accelerometers, gyroscopes and IMUs. In addition to a high-speed 3-dimensional camera system, the HMiLab utilizes wearable sensors. Recent advances in low-cost sensors and electronics have opened new doors to expanding the analysis of human motion. We are developing low-cost sensors to measure everything from knee rotation when climbing stairs to elbow flexion in the workspace.
