Point Laser Triangulation (PLT) probes have significant advantages over traditional touch probes. These advantages include throughput and no contact force, which motivate use of PLT probes on Coordinate Measuring Machines (CMMs). This document addresses the problem of extrinsic calibration. We present a precise technique for calibrating a PLT probe to a CMM. This new method uses known information from a localized polyhedron and measurements taken on the polyhedron by the PLT probe to determine the calibration parameters. With increasing interest in applying PLT probes for point measurements in coordinate metrology, such a calibration method is needed. [S1087-1357(00)01703-2]
