An apparatus and method for recording an image on the surface of a 3D object uses a laser projector that scans a light beam over the surface in an image pattern. The projector operates in a template imaging mode and an image recording mode where the beam scans at a speed that in a single pass / scan mode is typically four to five orders of magnitude slower than in the template imaging mode. A layer of a photosensitive material is applied to the surface of the object either partially or fully. Projection in the template imaging mode can guide the applying.

In one or multiple passes of the beam over the image pattern operating in the image record mode, the accumulated light energy dose density is sufficient to react the material and record the image.

This invention provides a system and method for determining position of a viewed object in three dimensions by employing 2D machine vision processes on each of a plurality of planar faces of the object, and thereby refining the location of the object. First a rough pose estimate of the object is derived. This rough pose estimate can be based upon predetermined pose data, or can be derived by acquiring a plurality of planar face poses of the object (using, for example multiple cameras) and correlating the corners of the trained image pattern, which have known coordinates relative to the origin, to the acquired patterns. Once the rough pose is achieved, this is refined by defining the pose as a quaternion (a, b, c and d) for rotation and a three variables (x, y, z) for translation and employing an iterative weighted, least squares error calculation to minimize the error between the edgelets of trained model image and the acquired runtime edgelets. The overall, refined / optimized pose estimate incorporates data from each of the cameras' acquired images. Thereby, the estimate minimizes the total error between the edgelets of each camera's / view's trained model image and the associated camera's / view's acquired runtime edgelets. A final transformation of trained features relative to the runtime features is derived from the iterative error computation.

By the use of an epsilon filter, in the case where a plurality of different illuminations exist, a boundary between the illuminations can be appropriately extracted, and an unnatural image pattern can be prevented from being generated, therefore subjectively preferable compression of a dynamic range can be achieved. An edge strength G(x, y) is calculated per position on an input image, and a threshold E(x, y) of an epsilon filter (12) is controlled on the basis of the edge strength G(x, y). The epsilon filter (12) filters the input image on the basis of the controlled threshold E(x, y). On the basis of the edge strength G(x, y), the threshold E of the epsilon filter (12) is adaptively changed according to a local gradient of a pixel value I(x, y), so in the case of using a linear lowpass filter or a fixed threshold epsilon filter, an illumination boundary can be more accurately extracted.
