Abstract
Systems for acquiring an approximation of the surface geometry of a 3-dimensional object include a self-powered wireless, non-contact optical scanner, the location and orientation of which may be tracked with respect to an object coordinate system, and a processor configured for projecting a pattern of structured light on the object, moving the pattern with respect to the object, acquiring images of the intersection of the light on the object over time, determining local coordinates of points on the intersection with respect to the pattern, tracking the position of the pattern, transforming the local coordinates to object coordinates, and accumulating the points as a model of the surface of the object. The systems may wirelessly and possibly compactly transmit geometrical data which characterizes an intersection for a given position of the scanner with respect to the object.
