Foreground and Background meshes are empty #186

Screenshot from 2024-03-12 16-52-27 To begin, I processed the video using Colmap with the following commands:

Convert the video to individual frames:

ffmpeg -i /project/gaussian-splatting/Museum.mp4 -vf fps=2 -vsync vfr -q:v 2 /project/gaussian-splatting/data/input/%06d.jpg

Convert frames to a suitable format:

python convert.py -s /project/gaussian-splatting/data

Next, I utilized Gaussian Splatting to generate the Gaussian representation of the scene:

Perform Gaussian Splatting:

python SuGaR/gaussian_splatting/train.py -s data/ --iterations 5000 -m gaussian_output/ Then, I executed SuGaR:

Run SuGaR with specified parameters:

python SuGaR/train.py -s data/ -c gaussian_output/ -r "density"

Please review this workflow and identify any potential issues that make the background and foreground meshes empty.

Same problems

Same problem. Did you solve it?

Heba2h commented 1 month ago

@tianf-code Yes we solved it, and mesh extraction was done successfully. The problem was from the output of colmap, it showed us that it was successfully done but actually the output from comlap alot of things were missed. U can check undistorted images if there’s many images or not
