Systems and methods for scan alignment

A method of measuring thickness of a workpiece, comprising:

• coupling a plurality of reflective targets to an edge of a workpiece having first and second sides;
• generating a first scan of the first side of the workpiece including detecting the plurality of reflective targets;
• generating a second scan of the second side of the workpiece including detecting the plurality of reflective targets;
• aligning the first and second scans;
• and
• determining a thickness of the workpiece based on data obtained from the first and second scans.

A system for measuring thickness of a workpiece, comprising:

• a set of reflective boundary targets configured for fastening to an edge of a workpiece;
• a set of facial targets configured for fastening to first and second opposing faces of the workpiece;
• a scanner configured to generate first and second scans of the first and second faces, detecting spatial locations of the boundary targets and facial targets;
• and
• a processor configured to align data sets from the first and second scans, and to calculate a thickness of the workpiece based on the data sets.
