REMAC - A VIDEO-BASED MOTION ANALYZER INTERFACING TO AN EXISTING FLEXIBLE SAMPLING SYSTEM

A new video-based movement recording system called REMAC is described in this article. The REMAC system is based on real-time processing of video images to recognize multiple passive markers and to compute thei r co-ordinates. It has a spatial accuracy of 1/13 000 of the viewing f ield in 2 dimensions with up to 18 markers and an adjustable frame rat e of between 40 and 105 Hz. Optionally, up to 36 markers may be tracke d at slightly lower accuracy. The REMAC system interfaces with an exis ting flexible sampling system (SC/ZOOM) and is synchronized with its s ampling of analog signals (10 Hz-26 kHz sampling frequency). The movem ent recordings can be processed as general channels in the sampling an d analysis system.
