The robot can also sort and select which details are to be picked when several
occurrences are sent to the robot, for example based on the signals from the
machine used in production.
Timeout
The Timeout parameter specifies a maximum period of time used for searching.
An image taken against a dirty conveyor belt often contains a lot of noise. This
noise results in a large number of edges being found, even in areas where there
are no details. Processing all these edges can take relatively long. With the Timeout
parameter, the maximum search time can be limited so that the identification time
does not affect the robot cycle time. If no timeout is set at all, the search could
take several minutes in the worst case.
Accuracy and Speed
The Accuracy and Speed settings can be used to customize the search. However,
you should remember that a higher speed will have a negative effect on the
accuracy, and a higher accuracy will have a negative effect on the speed. The
speed and accuracy settings should therefore be balanced against each other and
adapted to suit the current application. Setting both the speed and accuracy settings
to High will have the same result as setting them both to Medium.
To achieve a longer cycle time, the accuracy can be increased and the speed
decreased. To achieve shorter cycle times, the speed should be increased and the
accuracy decreased. In these cases the handling tools should be designed so that
they are more tolerant of varying results.
Allow shared edges
If shared edges are allowed, a found edge can be counted as a result for two or
more found positions. If shared edges are not allowed, shared edges are counted
as belonging to the result that meets the requirements most closely.
