看这两篇 都是很新的技术

这里顺便对3D重建方式做一个小小的总结
SFM(Structure from Motion), MVS(Multi View Stereo)
Key point detection, matching(sparse point cloud) →
根据特征点推出一般点的位置 → dense point cloud
Neural Field(NERF, Neural SDF(这个也算是neural)))
只要是用NN拟合
Nerf 得到的是nerual representation 图片性质
通过extraction 才能得到模型(点云 mesh voxel…)
训练时间长
Gaussian Splatting
把点变成gaussian
几何形状不好 存储高
