Patent Images

1. A method comprising:

  • projecting at least three light pattern elements toward a target at a diverse angular spacing relative to each other about a first axis;

    capturing at least one image of the target while illuminated by at least one of the pattern elements;

    moving the pattern elements relative to the target consistent with rotation of the projection about a second axis;

    disambiguating one pattern element from any other contained within an image of the target, at least in part based on the diverse angular spacing; and

    measuring by triangulation a location of points on a three-dimensional surface of the target.
