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
: ΔZ ≈ ΔX / tan(α)
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
: ΔZ ≈ ΔX * cos(β) / sin(α + β)
,
in case
α= β
(direct reflex) :
ΔZ ≈ ΔX / 2* sin(α)
