Scanner orientation
Task
For large smooth objects a global point grid is needed in order to precisely locate the scanner in space. The Linearis3D
Photogrammetry System creates such a global grid.
Procedure
The target points of the scanner manufacturer are placed on the object, e.g., a vintage car (Fig. 1). Coded
photogrammetry targets are added and a photogrammetric scale is positioned in the measuring volume. For a car-sized object
about 200 pictures are taken in rapid succession. Computation is fully automatic. With one click the point grid is exported.
The scanner's software imports the coordinates and uses them for orientation. Linearis3D export format is compatible with
leading scanner models.
Results
Scan results can be improved significantly.
