  annote =	 {We describe a system for measuring human breathing movements
                  by a photogrammetric method. This method is aimed at
                  quantitative evaluation of rehabilitation treatment
                  efficiency. The points of interest on human chest and
                  abdomen are marked by special simply detectable marks. The
                  calibrated system includs six photogrammetric cameras that
                  grab images of measured the subject during his free
                  breathing. The marks are automatically detected in images
                  and their 3D positions are computed by a photogrammetric
                  method. The measuring system is able to compute 3D positions
                  of special marks inside working space of the cameras with
                  spatial accuracy of approximately +-0.1mm at 1m measuring
                  distance.},
