Object Height Differences
If the objects on the conveyor strongly differ in height, the lines in the sensor will view a short
object from a different perspective than they view a tall object. To make sure that all objects are
in perspective even if they strongly differ in height, use of a telecentric lens setup is recommended.
A telecentric setup usually requires high illumination.
If the objects strongly differ in height and a telecentric setup is not used, haloing will be seen in
the areas where sharp height gradients are present.
