Range Laser Scanners: a suitable technology for markerless human motion analysis• Single-row range laser scanners measure the distance between themselves and the closest element, in a set of predefined directions that are usually located in a plane.Therefore, they can be used to analyse the geometry of a thin slice of the observed scene.• They derive the distance measures from the time-of-flight of an infrared signal (e.g. a pulse).A large number of precise distance measures can be taken at high frequency (e.g.274 directions scanned at 60Hz, or 16440 measures per second, in the case of the sensor BEA LZR-U901).• The suitability of range laser scanners depends on the speed of the observed elements, and is in general high for human motion [1].
