Surface based hole target for use with systems and methods for determining a position and a vector of a hole formed in a workpiece

A target for coupling to a hole formed in a workpiece and for use with a scanner in determining a position and a vector of the hole in scanned data, the target comprising:

• a shaft for coupling to the hole and having a centerline extending longitudinally along the shaft, wherein the shaft couples to the hole such that a centerline of the hole is collinear with the centerline of the shaft;
• a cylinder body extending from the shaft such that a centerline of the cylinder body aligns with the centerline of the shaft, wherein the cylinder body includes two parallel circular faces having volume therebetween, and wherein the cylinder body includes a cavity, and wherein the centerline of the cylinder body extends longitudinally along the cylinder body between the two parallel circular faces, wherein the position and the vector of the hole is based on an intersection of the centerline of the cylinder body with the centerline of the shaft;
• a first ring structure coupled to an end of the cylinder body and including an undercut on a portion connected to the cylinder body;
• and
• a second ring structure positioned between the cylinder body and the shaft, and including an undercut on a portion connected to the cylinder body.

A method for determining a position and a vector of a hole formed in a workpiece based on scanned data of the workpiece, the method comprising:

• causing a scanner to scan a target that is inserted into a hole formed in the workpiece, wherein the target includes a shaft coupled to the hole in the workpiece and the target comprises a cylinder body extending from the shaft, wherein the shaft couples to the hole and the cylinder body extends from the hole such that a centerline of the hole is collinear with a longitudinal axis of the cylinder body;
• receiving scan data, from the scanner, including a plurality of data points representative of a surface area of the cylinder body of the target and data points representative of a surrounding workpiece;
• interpolating, by a processor, the longitudinal axis of the cylinder body based on fitting the plurality of data points representative of the surface area of the cylinder body to a cylindrical shape, wherein the longitudinal axis of the cylinder body extends longitudinally along the target;
• determining, by the processor, a position of the hole and a vector of the hole formed in the workpiece based on an intersection of the longitudinal axis of the cylinder body and a plane of a surface of the workpiece;
• and
• generating, by the processor, a three-dimensional (3D) model of at least a portion of the workpiece using the position of the hole and the vector of the hole formed in the workpiece.
