Abstract: A method and a system for bump's inspection are disclosed. The inspection done by comparing the volume of the bump's outside contour and the volume the solid materials from which the bump is made and/or analyzing the bump's solid materials ratio. Principally, the inspection id done by preparing an empiric reference table of the emitted energy received from the solid materials, from which a reference proper bump with a given volume is comprised, using ED-XRF (Energy-Dispersive-X-ray-Fluorescence analysis) analyze; obtaining a first calculated volume of the bump, using a 3D image-processing method; adapting the reference table according to the difference between the given volume and the first calculated volume of the bump; performing a second volume calculation of the bump by applying ED-XRF technology. The difference between the first and second volume calculations and the solid material combination are used to inspect the bump.

Abstract: Supplemental reference surface devices are provided for use in three-dimensional modeling of intra-oral scenes using identifiable positional characteristics from structured illumination or other techniques. Reference surface devices having at least one substantially plane smooth non-polished face are disclosed for locating the positions of intra-oral features, and for stitching together separate 3D tiles according to the identifiable positional characteristics. Reference can be attached to an intra-oral feature in or adjacent to the imaged intra-oral scene. Disclosed are reference surface devices having orientation and position indicia, as well as reference surface devices having a multiplicity of faces distributed in spatial position and angular orientation to facilitate correlation of 2D images obtained by imaging systems in different positions.

Abstract: A method for creating three-dimensional models of intra-oral scenes features. The intra-oral scene is illuminated by a two-dimensional array of structured illumination points, with anti-aliasing achieved by using stored two-dimensional patterns of pixels for anti-aliasing. Using a single camera to form images reduces the amount of apparatus necessary to introduce into the patient's mouth. Three-dimensional models are obtained from the single image by triangulation with a stored image of the structured illumination onto a reference surface such as a plane. Alternative methods include the use of “bar-coded” one-dimensional patterns.

Abstract: A method and a system for three-dimensional modeling of a three-dimensional scene features, are described. According to the present invention, a reference-image is captured from a known angle while an array of two-dimensional random patterns is projected onto a reference surface from another known angle. The reference image is turned in relation to the reference surface. Then, an image of the scene is captured while the array of two-dimensional random patterns is projected onto it from the same angles. By matching the patterns of these images and measuring the movement between the two projected patterns, the third dimension is computed using triangulation techniques.
