Geometry 3
The camera views the object under an angle α, while the laser line is projected under a different
angle β.
The height resolution can be approximated: ∆Z ≈ ∆X * cos(β) / sin(α + β),
in case α= β (direct reflex) : ∆Z ≈ ∆X / 2* sin(α)
Geometry 4
The camera views the object under an angle α, while the laser line is projected under a different
angle β at the camera side.
The height resolution can be approximated: ∆Z ≈ ∆X * cos(β) / sin(α - β),
