Abstract:To solve the problem of scanning blind-area appearing in scanning 3D relic, this paper gave a fast and efficient method of filling based on layer associations. The method improved the traditional method of picking up boundary points, of inserting the discrete points and triangulation, to make them suitable. The method also made the above three kinds of methods and the quality triangle parallel, in order to improve efficiency and accuracy of filling. The method took full advantage of the distance-direction relationship between the boundary points in which the innermost layer that in blind-area, to insert the discrete points and triangulation layer by layer, and using of topological relations between vertices adjacent layers, to optimize triangle. While dynamically update the current layer, layer by layer. The experiment shows, the new method can fill up the 3D relic surface speedily and smoothly.......
