The application of video imagery for photogrammetric tasks may be divided according to the task into on-line or off-line use. In Finland, the first successful on-line systems were installed for the position measuring of car bodies in Spring 1992. The on-line applications have grown interest within industrial production because they are operative and a payback period is thus countable. As it regards the off-line use, the situation is different and the efficiency in 3D data acquisition seems to play the decisive role. In the paper the different characteristics in performing the on-line and off-line videogrammetry are presented. The 3D measurements are exemplified with the applications. These cover both existing references in industrial `on-line' applications and ongoing development of `off-line' 3D object digitizing procedures.
