在InstantSplat框架中,得到一个全局一致的3D表示涉及到几个关键步骤,这些步骤结合了端到端的密集立体模型(DUSt3R)和3D高斯喷涂(3D Gaussian Splatting)技术。以下是这个过程的概述:1)粗略几何初始化(Coarse Geometric Initialization):使用DUSt3R模型,该模型接受一对立体图像作为输入,并输出每个像素对应的3D点图和置信...
作者将作者的稀疏LGS与最近的基于语言嵌入的Gaussian splatting方法,如LangSplat [30]和LEGAussian [34]进行了比较。对于LERF数据集,在原始工作流中使用COLMAP无法获得相机姿态,因为视角非常稀疏且场景复杂。因此,在对LERF数据集进行实验时,作者使用所有图像来获取相机姿态和初始点云。此外,由于尚未有专门针对3D语言场稀...
