Systems and methods improve the accuracy of spatial coordinate measurements by optical digitizers by obtaining a separate distance measurement, which may be via direct ranging rather than triangulation, and combining the distance measurement with the spatial coordinate measurements to improve the accuracy of the three-dimensional spatial coordinate measurement.
