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
