 | Detect Objects FAQs |
Q: Reposition Region of Interest and Reference Coordinate System are dimmed. How can I make these options available?
Insert a Set Coordinate System step before this step to make the Reposition Region of Interest and Reference Coordinate System controls available.
Q: How can I filter the objects in my image based on other features than their size?
You can insert a Vision Assistant step to do more advanced particle filtering than what is available in the Detect Object step.
Q: How can I make sure the objects are always returned in the same order?
When using the results of the Detect Objects step in further processing steps, for example in the Geometry, Logic Calculator, and Calculator steps, the order of the objects is important because it identifies the object. Slight variations in the relative vertical position between two objects may change the order in which these objects are detected by the Detect Objects algorithm. Use the Sort by control to specify a sorting criteria, such as X position or size, that is robust for your specific setup and that always returns the detected objects in the same order.
