Abstract
An automated measurement system includes multi-axis imager configured to receive images of a workpiece wherein the images include visual information about the workpiece at a plurality of focus planes or visual information about the workpiece between at least two focus planes. The multi-axis imager is also configured to determine a point cloud of a plurality of 3 D data points wherein each of the plurality of 3 D data points represents an intersection of one of the plurality of focus planes with a surface of the workpiece or positional information of the workpiece in a de-focused area between the at least two focus planes. The multi-axis imager is further configured to determine a plurality of dimensions of features of the workpiece and compare the determined plurality of dimensions of the features to manufacturing specifications corresponding to at least some of the determined plurality of dimensions of the features.
