I have a question about using Inspection level one with multiple Geometric and Blob models. In the manual it says that the best item with the highest score will be selected as the pick item by the robot. The Geometric models have a score but the Blob model doesn’t? So how will Pickmaster use the three model results to decide what item to pick?
A geometric model receives a sort value that is determined by the vision search algorithms (assuming the “Score as sort value” is checked for the geometric vision model in PickMaster 2.30 and later). This score/sort value indicates how good/bad an item fits to a model. Please note that an item recognized by an inspection I/inspection II model and is classified as rejected also receives a score/sort value.
An item that should be recognized by a blob model can either pass or fail the requirements of that model. If found the blob sort value can be set to any predefined value in the blob configuration window. In the example below, we assume that the sort value is set to 0 (default in PickMaster releases earlier than 2.30).
If three objects (A geometric/rejected, B geometric/accepted and C blob) are found within the distance entered in the position filter, either A or B (the one with the highest score/sort value) will be used as both of them has a score >0.
In addition to this, if “same level only” is checked (PickMaster 2.22 and newer), both A and B will be distributed (and picked/placed by the robot) as A is rejected and B accepted. Using “Same level only” will compare all rejected as a group and all accepted as a group and use the ones with the highest score/sort value from each group.
However, if “Same level only” is not checked, A and B will be compared and the one with highest score will prevail (be picked).
