Identification and labeling of beam images of a structured beam matrix

An object surface characterization system for characterizing a surface of a target, the system comprising:

• a light projector;
• a camera;
• a processor coupled to the light projector and the camera;
• and
• a memory subsystem coupled to the processor, the memory subsystem storing code that when executed by the processor instructs the processor to perform the steps of:
• directing the light projector to provide a plurality of light beams arranged in a beam matrix of rows and columns, wherein the light beams impinge on the surface of the target and are reflected from the surface of the target;
• directing the camera to capture the plurality of light beams of the beam matrix after reflection from the surface of the target;
• locating a reference light beam in the captured beam matrix;
• locating a row pivot beam in the captured beam matrix based on the reference beam;
• locating remaining reference row beams of a reference row that includes the row pivot beam and the reference beam;
• locating a column pivot beam in the captured beam matrix based on the reference beam;
• locating remaining reference column beams of a reference column that includes the column pivot beam and the reference beam;
• and
• locating remaining ones of the light beams in the beam matrix.
