Notes on measuring non-cubic objects
•
In principle, non-cubic objects can also be measured with the MDA Vision.
•
The accuracy to be achieved depends on the object shape, object surface as well as
the resulting shadowing.
•
The following examples show how acceptable results can be obtained when measuring
non-cubic objects. The accuracy values specified in the technical data are not valid in
these cases.
NOTE
The illustrations below show an object in two dimensions in the front view. This
applies equally in three-dimensional space.
▸
When measuring non-cubic objects, make sure that the object is not shadowed and
has all sides visible to the camera.
NOTE
Edges that cannot be “seen” by the 3D Visionary
-S due to shading are not
considered in the contour detection and are not included in the dimension calculation.

▸
Place objects with small irregularities on the scale so that the smallest part faces up.
NOTE
Otherwise, there is a risk that this part will be disregarded due to shading.
