Robust photogrammetric method to estimate geometric parameters of spatial objects with axial symmetry

The article deals with a robust photogrammetric method to measure the geometric parameters of large scale objects with axial symmetry. The method is based on measuring the 3D-coordinates of the centers of circular retroreflective targets placed on the object in planes perpendicular to the axis of symmetry with the minimum moment of inertia. There has been developed a two-stage outlier filtering algorithm and its software implementation.
