Micrometer head displacement system utilizing imaging

A micrometer head displacement system, comprising:

• an imaging portion comprising at least one camera and configured to acquire images of a micrometer head, the micrometer head comprising:
• a coarse scale and a coarse fiducial line configured to move relative to one another for indicating a coarse scale measurement;
• and
• a fine scale and a fine fiducial line configured to move relative to one another for indicating a fine scale measurement;
• a display configured to indicate the micrometer head displacement, wherein the display is configured to provide a positive indication confirming proper positioning of the imaging portion relative to the micrometer head;
• one or more processors;
• and
• a memory coupled to the one or more processors and storing program instructions that when executed by the one or more processors cause the one or more processors to at least:
• acquire at least one image of the micrometer head from the imaging portion;
• determine a coarse measurement based at least in part on the at least one image, wherein the coarse measurement corresponds to a coarse relative position between the coarse scale and the coarse fiducial line;
• determine a fine measurement based at least in part on the at least one image and based on calculating an interpolated position of the fine fiducial line, wherein the fine measurement corresponds to a fine relative position between the fine scale and the fine fiducial line;
• and
• determine a micrometer head displacement based at least in part on summing the coarse measurement with the fine measurement.
