Abstract
A method and system for reconstructing the shape of a 3D object. The method comprises: immersing a 3D object into a liquid from multiple angles, and simultaneously tracking and recording changes in liquid level to construct several non-uniform cross subject slices; performing resampling measurement on the non-uniform cross subject slices to obtain uniform slices and liquid level information corresponding thereto; using a Gaussian kernel to smoothen the liquid level information corresponding to the uniform slices; constructing a sparse linear equation according to the smoothened liquid level information to approximate an immersion process of the 3D object in the liquid during immersion; solving the sparse linear equation system to reconstruct a voxel of the 3D object; converting the reconstructed 3D object voxel into a grid; and smoothening the grid to finally reconstruct the 3D object.
