COLMAP - Structure-from-Motion and Multi-View Stereo
Splitting my last PR into 2 Part 1. These functions are needed for MP-SfM. They are also generic extensions of COLMAP that could be used elsewhere. See original PR https://github.com/colmap/colmap/pull/3269
**Describe the bug** I had some trouble building Colmap on my Fedora 42 system, mainly because I am not so well versed with tracing build errors. **To Reproduce** Steps to...
### Summary Pose prior covariance matrices are used during pose prior BA but not for the Sim3 alignment. In the case where pose priors have significantly lower/higher uncertainties for different...
Splitting my last PR into 2 Part 2. These functions are tailored for MP-SfM, and can not be used in pure COLMAP. See original PR https://github.com/colmap/colmap/pull/3269

### Summary This PR introduces the core functionality required for MP-SfM. It adds new Ceres cost functions and integrates them into COLMAP’s pipeline via ExtendBundleAdjusterWithDepth, with full Python bindings. Additionally,...
Using a fork of PoseLib: https://github.com/PoseLib/PoseLib/compare/master...sarlinpe:PoseLib:sarlinpe/generalized-5pt
Changelog for 3.11 says "New pose prior based incremental mapper that can leverage absolute pose priors from e.g. GPS measurements." I am wondering how this is done. What commands are...
I’m using the SiftGPUFeatureExtractor class in COLMAP to extract image features, but the extraction fails most of the time — out of 10 attempts, maybe only 1 succeeds. When it...
- Add an option in the CLI to specify the Cartesian frame into which GPS coordinates are transformed, including the newly added UTM coordinates in #3030 - Add 'utm' option...
