My PickMaster is identifying oval objects with a significant difference between its major and minor axis. When the trigger distance is defined according to the oval moving in its major axis direction, it sees the object too many times when it moves in its minor axis direction, the robot tries pick the same object more than once . When the trigger distance is defined according to its minor axis direction, it does not see the major direction oriantation as the image area is too small causing the image not to be identified at all. The diagram of the scenario is given on the image below:
Please assist on how I can configure the trigger distance such that I can accomodate bot the scenarios.
You can configure the Position Source so that it captures several pictures of the same object as it passes under the camera, and still only sends one target per product to the robot. This type of situation is the reason why PickMaster has
The position filter
The overlap filter
The position filter makes sure that only one hit within the specified radius is generated and sent to the robot.
The overlap filter makes sure that eventhough an object is identified several times in a sequence of images as the conveyor moves past the camera, only one hit is sent to the robot.
Example with overlap filter 10mm: If a hit in image nr x is closer than 10mm to a hit in image nr x+1 (taking conveyor movement into account) only the hit from image 1 is sent to the robot.
The standard value for both filters is 10mm. So unless you have get very poor hits from the vision system (pick point varying several mm:s) you should not have a problem. So to fix the problem either define a vision model that gives a more accurate result or increase the filter value of both filters roughly to the minor axis diameter of your objects.
