以往神经三维重建需要多视角数据和位置(Colmap),在稀疏视角下,特征匹配较少,SfM不够有效,会有累计误差。(关于SfM:Structure from Motion,运动结构恢复该方法能够从相机连续拍摄的二维图像序列中,恢复出场景的稀疏点云信息和相机的运动轨迹,关于详细内容高博的SLAM14讲中应该有讲到) 关于InstantSplat InstantSplat利用自...

InstantSplat: Sparse-view SfM-free Gaussian Splatting in Seconds This repository is the official implementation of InstantSplat, an sparse-view, SfM-free framework for large-scale scene reconstruction method using Gaussian Splatting. InstantSplat supports 3D-GS, 2D-GS, and Mip-Splatting. Table...
We demonstrate that using SART provides better reconstruction results in sparse-view settings using fewer projection images. We provide extensive experimental results for both contributions on both simulated and real data. Moreover, our code will also be made publicly available....
In the medical CT fi eld, sparse-view sampling has prac-tical implications in reducing ionizing radiation, which is harmful to people’s health, decreasing the scanning time and improving the scanning limits in many scenarios [2, 3]. In the industrial CT, when it was limited by scanning ...
Real-time free-view human rendering from sparse-view RGB inputs is a challenging task due to the sensor scarcity and the tight time budget. To ensure efficiency, recent methods leverage 2D CNNs operating in texture space to learn rendering primitives. However, they either jointly learn geometry...

Creating 3D assets from single-view images is a complex task that demands a deep understanding of the world. Recently, feed-forward 3D generative models have made significant progress by training large reconstruction models on extensive 3D datasets, with triplanes being the preferred 3D geometry ...
