LineGS : 3D Line Segment Representation on 3D Gaussian Splatting

Understand

Abstract representations of 3D scenes play a crucial role in computer vision, enabling a wide range of applications such as mapping, localization, surface reconstruction, and even advanced tasks like SLAM and rendering.

• Among these representations, line segments are widely used because of their ability to succinctly capture the structural features of a scene.
• However, existing 3D reconstruction methods often face significant challenges.
• Methods relying on 2D projections suffer from instability caused by errors in multi-view matching and occlusions, while direct 3D approaches are hampered by noise and sparsity in 3D point cloud data.
