Introduction
A 3D camera differs from a normal 2D camera. The image that comes into
FlexLoader Vision is rectified, which means that it does not have any perspective
faults. The grey scale corresponds to the height so that it is possible to find the z
coordinates.
Some settings must be made in order for FlexLoader Vision to search in an efficient
way.

Image size
Depending on the application, the interesting area for detail search can vary quite
a lot. The Image size settings let you determine exactly which area, i.e. what
volume, should be displayed and analyzed by FlexLoader Vision.
It is important that the measurement volume is slightly larger in the x- and y-axis
than the actual pick volume. For a pallet it is important for example that the whole
pallet collar is always visible in the image.
When operating without interlayers, the lowest height value (Z min) should be
specified so that the floor or bottom of the pallet is not shown in the image. The
FlexLoader Vision image must always contain enough height that the last layer of
details can be found but not the surface that they are lying on.
In contrast, when operating with interlayers, the lowest height value must be
adjusted so that the floor or bottom of the pallet is shown in the image.
