Not good performance in an open source dataset

Nice job. I tested your code on an open source which could be download from https://doc.arcgis.com/en/drone2map/latest/help/sample-data.htm.
But the reconstructed geometry is not so reasonable. Is there any possible reason?
The first one was trained based on neuralangelo-colmap_sparse-50k.yaml. In the second experiment, I centered and scaled the 3D point cloud into NDC space and set the sampling range of ray marching to the outer bounding box of the point cloud. Other settings are the same. But both of the results are not so good.
Thank you for the results! I will review the data in more detail
We have built a docker for this repo, maybe you could run the latest with this environment to see whether it could fix
docker pull hugoycj/instant-angelo
docker run -it hugoycj/instant-angelo
Thank you so much for the reply. I will try it later.
By the way, the current results are generated using the neuralangelo-colmap_sparse.yaml
configuration. We have temporarily discarded the neuralangelo-colmap_sparse-50k.yaml
since we found limited quality improvement and it is less robust than the neuralangelo-colmap_sparse.yaml
. For detailed reconstruction, we sincerely recommend the neuralangelo-colmap_dense.yaml
which utilizes the dense point cloud from MVSNet or even from other MVS tools like drone2map as a prior.
