6.5.7 Shadowing Effects
- Receiver: The laser line can disappear completely or partially behind steep edges. The receiver then does not „see“ these areas.
- Laser line: The fan-shaped form of the laser line inevitably results in partial shadowing at vertical edges. In order to make these
areas visible, only changing the sensor or object position helps.
As a general rule, measuring objects with steep edges cannot be one hundred percent measured using laser triangulation. The miss-
ing areas can only be supplemented or interpolated using suitable software.
