ABSTRACT:
A feature of a workpiece can be identified. Two-dimensional data of at least a region of a workpiece and three-dimensional data of a portion of the region of the workpiece are acquired, such as by illuminating at least the region with at least a first light source disposed at a first angle of incidence relative to a plane of the region and illuminating the portion with a second light source, such as at least one laser, disposed at a second angle of incidence greater than the first angle of incidence. An estimated location of an attribute of a feature of the workpiece is determined from the three-dimensional data, and the feature is identified by analyzing the two-dimensional data in an area surrounding the estimated location of the attribute. Attributes of features can include without limitation a point along a line of an edge.
