摘要:
A method for color texture imaging of teeth with a monochrome sensor array obtains a 3-D mesh representing a surface contour image according to image data from views of the teeth. For each view, recording image data generates sets of at least three monochromatic shading images. Each set of the monochromatic shading images is combined to generate 2-D color shading images, corresponding to one of the views. Each polygonal surface in the mesh is assigned to one of a subset of the views. Polygonal surfaces assigned to the same view are grouped into a texture fragment. Image coordinates for the 3-D mesh surfaces in each texture fragment are determined from projection of vertices onto the view associated with the texture fragment. The 3-D mesh is rendered with texture values in the 2-D color shading images corresponding to each texture fragment to generate a color texture surface contour image.
