[bug] Segfault during SFM triangulation #2901
Description
Describe the bug
Using the 2 sided Photogrammetry pipeline, computation of SFMTriangulation nodes always fails with a segfault. The issue appears to be either configuration and/or dataset specific as I have had success using this pipeline template before when using this Meshroom build.
To Reproduce
Steps to reproduce the behavior:
- Create new project from pipeline
- Modifications I made: guided matching on all matching nodes and describer density and quality to high
- Compute at least up to any of the SFMTriangulation nodes
- See error
Expected behavior
The SFMTriangulation nodes to successfully compute
