Abstract

Technologies for determining positional coordinates on the surface of an object are disclosed. In some embodiments the technologies utilize a code drum to encode incident light into structured light and non-structured light that is projected on the surface of the object being measured. The code drum may include a plurality of hybrid cyclic binary code (HCBC) patterns, wherein the plurality of HCBC patterns include a plurality of weighted numbering system patterns, and a plurality of unweighted numbering system patterns. Systems and methods for measuring positional coordinates on a surface of an object being measured are also described.
