The current structure from motion (SFM) module from openCV's extra modules only runs on Linux.
As such, I used docker on my Mac to reconstruct the 3D points.
Current docker environment uses Ceres Solver 1.14.0 and OpenCV 3.4.1
# Build the docker image
docker build -t opencv-sfm .
# Run the docker container mounting `reconstruction` folder to `/app`
docker run -it -v <path_to_reconstruction_folder>:/app opencv-sfm /bin/bash-
Download 2D temple images from http://vision.middlebury.edu/mview/data
-
Save list of images to
images.txt:
# images.txt will contain lines of filepath
# /app/temple/temple0302.png
ls temple/*.png > images.txt
sed -i -e 's/^/\/app\//' images.txt- In the docker container, compile the cpp file
g++ example_sfm.cpp -L/usr/local/lib/ -lopencv_core -lopencv_sfm
- Run the example with the list of images
