Abstract:

According to existing problems of traditional shape based interpolation, a novel method of 3D surface reconstruction was proposed, that innovatively uses the shape based interpolation guided by maximal discs. The method is summarized as follows: maximal discs are determined by traversing all the pixels of distance images that are obtained using the Chamfer algorithm; after redundancy removal and projection, final discs are obtained  which are used to determine the ultimate interpolation direction with an optimized centroid formula; finally 3D surface reconstruction is achieved according to the interpolated distance values of all pixels. Simulation result showed this method could accurately implement 3D surface reconstruction.

Key words: shape based interpolation, maximal discs, surface reconstruction, simulation, 3D ultrasonic imaging system
