ArXiv

Analysis

This paper addresses the challenge of reconstructing 3D models of spacecraft using 3D Gaussian Splatting (3DGS) from images captured in the dynamic lighting conditions of space. The key innovation is incorporating prior knowledge of the Sun's position to improve the photometric accuracy of the 3DGS model, which is crucial for downstream tasks like camera pose estimation during Rendezvous and Proximity Operations (RPO). This is a significant contribution because standard 3DGS methods often struggle with dynamic lighting, leading to inaccurate reconstructions and hindering tasks that rely on photometric consistency.

Key Takeaways

•Proposes a novel pipeline for 3D spacecraft structure reconstruction using 3D Gaussian Splatting.
•Addresses the challenge of dynamic lighting conditions in spaceborne imagery.
•Incorporates prior knowledge of the Sun's position to improve photometric accuracy.
•Improves camera pose estimation during Rendezvous and Proximity Operations (RPO).
