- Abstract
- 3D Gaussian Splatting (3DGS) is a state-of-the-art novel view synthesis technique that enables photorealistic rendering in real-time, and is emerging as a suitable technology for immersive virtual reality (VR) applications. However, 3D spaces generated from an initial image set often suffer from visual artifacts, such as surface holes and textures with low detail, which disturb user immersion when experienced via a head-mounted display (HMD). To resolve these artifacts, the method of acquiring additional images and reperforming Structure-from-Motion (SfM) leads to a shift in the entire coordinate system. This shift causes misalignment of pre-positioned virtual objects, which leads to inefficiency in the development pipeline. In this study, we propose a pipeline that anchors the coordinate system of the initial SfM model as the reference coordinate system. The camera poses of additional images are estimated and registered with respect to this fixed coordinate system. Consequently, our method generates an enhanced 3D Gaussian space with significantly reduced visual artifacts while maintaining the existing 3D scene layout.
