Abstract: Systems and methods for measuring a surface of an object. The system, in one embodiment, includes a laser projector device mounted at a fixed location relative to an object being formed by a fabrication process, and a videogrammetry device mounted at another fixed location relative to the object. The laser projector device includes a laser element mounted on a two-axis gimbal assembly, and the gimbal assembly directs laser beams from the laser element onto target points on a surface of the object. The laser projector device measures angles of the laser beams to the target points, while the videogrammetry device simultaneously performs measurements of the target points by capturing video images of the laser beams reflecting off of the target points. A controller processes the measurements from the laser projector device and the videogrammetry device to calculate x, y, z coordinates of the target points in a 3D coordinate system.
