    Stanowisko wizyjnego śledzenia odkształceń metalu w procesie obróbki plastycznej na zimno
    (Wydawnictwa AGH, 2010) Pociecha, Daniel; Jabłoński, Mirosław
    The paper presents metal deformation trace vision station, in cold tube pilger rolling process. Aluminium tube was prepared, with cooper grid on their surface. Measurement of metal deformation is possible, when grid point's displacement is traced. During rolling process, photos were taken. Using those photos, three-dimensional coordinates of tube grid points were determinate. Stereophotogrammetric method was used to point's coordinate's calculation. Before stereophotogrammetric calculation, annotation of all points which are visible on photos is essential. Two methods of point annotation - manual and automatic - are presented in paper.
