LIGHTING COMPENSATED DYNAMIC TEXTURE MAPPING OF 3-D MODELS

摘要

The present disclosure describes methods, systems, and devices for combining multiple images onto a 3D model. The textures of the images are applied to the 3D model dynamically so that the textured 3D model is viewable from different viewpoints in real time. The present disclosure also describes methods, systems, and devices for selecting the images and portions of the selected images to map to defined areas of the 3D model. In addition, the present disclosure describes how to remove the effects of directional lighting from the images. Some aspects of the present disclosure are particularly useful in the context of dental preparations. In some instances, a 3D digitizer is used to produce 3D models of dental preparations that are rendered on a display in real time and are fully 3D dimensional, while accurately depicting the surface textures of the item(s) being digitized.
