REMAC: A video-based motion analyser 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 their co-ordinates. It has a spatial accuracy of 1/13000 ot the viewing field in 2 dimensions...

Description
Summary: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 their co-ordinates. It has a spatial accuracy of 1/13000 ot the viewing field in 2 dimensions with up to 18 markers and an adjustable frame rate of between 40 and 105 Hz. Optionally, up to 36 markers may be tracked at slightly lower accuracy. The REMAC system interfaces with an existing flexible sampling system (SC/ZOOM) and is synchronized with its sampling of analog signals (10 Hz–26 kHz sampling frequency). The movement recordings can be processed as general channels in the sampling and analysis system.
