Sorry for the late reply, this is a very good question! For two images w/ intrinsics, you can use the code here to use PoseLib to estimate the relative pose. For multiple images w/ or w/o intrinsic, please use DetectorFreeSfM, an SfM framework from our freshly released CVPR 2024 work, designed for detector-free matching, which won first place in the Image Matching Challenge 2023.
