Geometry 1
The laser line is projected perpendicular to the object surface, while the camera views the object under
the triangulation angle α.
The height resolution can be approximated: ∆Z ≈ ∆X / sin(α)
Geometry 2
The camera views the object perpendicularly to its surface, while the laser line is projected under the
triangulation angle α.
The height resolution can be approximated: ∆Z ≈ ∆X / tan(α)
