Abstract:
1. A machine vision inspection system operable to inspect potentially interfering features on a workpiece, the machine vision inspection system comprising: a control system comprising a memory element and an excluded region generator; an imaging system operable to provide workpiece images; a display usable to display workpiece images and user interface elements; a user interface usable to define a sequence of workpiece inspection operations including video tool operations which analyze workpiece images, detect edge points of a workpiece feature, and characterize at least the location of the workpiece feature; and a plurality of video tools including a robust video tool that performs edge detection, the robust video tool comprising: wherein: the at least one previously characterized feature is a feature characterized by using one of the plurality of video tools to analyze a workpiece image to detect edge points of the previously characterized feature and characterize a dimensional parameter of the previously characterized feature based on the detected edge points, and the excluded region generator is configured to determine the excluded region based on the at least one previously characterized feature.
