SGCR: Spherical Gaussians for Efficient 3D Curve Reconstruction

Figure 1 . We present a novel method using 2D images to generate Spherical Gaussians, enabling the accurate representation of 3D edges. Spherical Gaussians combine the advantages from 3D Gaussian Splatting and the ability to preserve excellent 3D structures. With a corresponding curve extraction algorithm, Spherical Gaussians efficiently reconstruct 3D edge curves by only 2D supervision.
