Guidelines for Best Results:

  • Please print these targets using a laser printer (not an ink jet printer)
  • The angle of incidence between the laser beam and checkerboard targets should not be smaller than 45°.
  • Depending on the chosen scanning resolution, the detection of checkerboard references in the scans by SCENE may get unreliable beyond a certain distance to the scanner. E.g. when using A4 checkerboard references and scanning with a resolution of 1/4, the distance to the scanner should not be greater than 15m. Larger distances can easily be achieved by enlarging the size of the target or scanning with a higher resolution.
  • Checkerboard targets should not be rotated by 45° in relation to the scanner's axis.
  • Have sufficient scan points on the checkerboard targets. They need four or more scan points per quadrant.
  • Checkerboard targets should not be attached to a curved surface
