…is therefore
required to take line straightness into account
and produce accurate measurement results.
Although laser triangulation systems using
laser line projection offer greater speed and
accuracy than most other 3D vision technologies, system simplicity is deceptive.…

…These distorted
perspectives can be used for an exact geometric
reconstruction of the surface shape.
In a typical 3D triangulation sensor, the laser line
provides two of the three dimensions of the object. The
third is obtained by moving the object with respect to
the…
