Claim 8:
9. A system, comprising:
a light source configured to project a predetermined pattern that lacks reflection symmetry;
a detector configured to capture an image of a part illuminated by the light source; and
a processor communicatively coupled to the detector, the processor configured to:
classify at least one reflection of the predetermined pattern based on a comparison of the at least one reflection to an expected pattern such that each first-order reflection from the at least one reflection is classified into a first class of reflections and each second or higher-order reflection from the at least one reflection is classified into a second class of reflections;
identify pixels in the image that match a color of at least a portion of the predetermined pattern; and
compare a pattern of the identified pixels to the expected pattern, and

wherein classifying the at least one reflection of the identified pixels is based on comparing the identified pixels to the expected pattern.
