•
Detection height range: This parameter ensures that only objects inside of a given
height range from the camera view plane will be detected as possible workpieces. Use
the parameter when detecting tall workpieces, so that only the top part is used to
compute the position of the workpiece. Increase the robustness to disturbances like
shadows or reflections, as these usually appear at camera view plane level. It is
recommended to have a range large enough to allow variations in the height of the
workpieces. The
eect can be seen in the textured zone in the image feed, which
indicates the foreground.
•
Background sensitivity: This parameter makes the task detect the workpieces that are
more similar in color to the background. Use the parameter with care as the greater its
value is, the less robust the detection is to lighting changes and shadows. The eect
can be seen in the textured zone in the image feed, which indicates the foreground.
•
Pixel
filter size: Defines the size of the filter which is used to reduce the noise in the
image. High values will eliminate small details to focus on the bigger defects. Low
values can lead to image noise that
aects the outcome of the inspection. For most
applications, you do not need to adjust this parameter.

Adjust an inner region of interest. This region specifies which areas should be considered
when performing the inspection. Defects outside of the inner region of interest will not
aect the outcome of the inspection. To modify the inner region of interest, click the
button. Adjust this region similarly to the main region of interest.
