On the FARO Laser Scanner, the laser is reflected off the mirror from both the front and back. So, the scanner only rotates 180° along the horizontal axis to capture a 360° scan, as shown in this image. When in Planar View, you may see what looks like a mis-alignment at the point where the scanner starts and stops its rotation. This point is also referred to as the seam.
Here is what you can do to check if a mis-alignment really exists around the seam area.
- Make a selection around the seam area.
- Right-click on the selection and select View > 3D View.
- In the 3D View, rotate around the seam area looking for any mis-alignment.
If the scanner is performing within factory specifications and you see a mis-alignment, it should not exceed the factory-stated tolerances for your scanner. See the FARO SCENE Training Manual and search for Start/Stop Point for more information.
