Python scripts to triangulate ground control points (GCPs) in COLMAP and check their 3D position agiainst a ground truth with an Helmert transformation.
In Windows open Anaconda prompt as administrator
>conda create --name colmap_tri
>conda activate colmap_tri
>pip install opencv-contrib-python
>conda install matplotlib
For inputs and options:
>conda activate colmap_tri
>python main.py --help
Run for example:
python main.py -i ".\COLMAP_GroundControlPoints\sample_test\imgs" -e ".jpg" -p ".\COLMAP_GroundControlPoints\sample_test\target_projections" -s ".\COLMAP_GroundControlPoints\sample_test\colmap_sparse" -g ".\COLMAP_GroundControlPoints\sample_test\Ground_Truth.txt" -c "./path/to/parent/folder/colmap_exe" -a "./AlignCC_for_windows" -r 0.249 -d " "
*All images in ./sample_test/imgs must be registered in the sparse model *This repository contains some scripts to extend "COLMAP 3.6 and 3.7" (https://colmap.github.io/) functionalities. If you find these scripts useful, please consider citing the paper for which these scripts were developed:
