Hello, thanks for your amazing work for using the learning technique to improve the accuracy of SfM !
There is no definition of colmap::BundleAdjustmentOptions
in bundle_optimizer_test.cc
, I found the definition of colmap::BundleAdjustmentOptions
is in colmap.
When I use CMake to compile the the project, I just comment the line of #PIXSFM_ADD_TEST(bundle_optimizer_test src/bundle_optimizer_test.cc)
of pixsfm/bundle_adjustment/CMakeLists.txt
. There is no error in compilation.
The requirement of pycolmap
is installed, but I don't know colmap
is necessary to run the pixsfm
.
when refiner = PixSfM(),
super(_open_file, self).init(open(name, mode))
FileNotFoundError: [Errno 2] No such file or directory: '/home/ai/workspace/pixel-perfect-sfm/pixsfm/features/models/checkpoints/s2dnet_weights.pth'
Thanks for sharing these excellent work.
This strange error occured during pip installing, i found no info about it on google
ubuntu 20.04
gcc 9.4.0
cmake 3.21.6
ceres 2.2.0
python 3.9.7

Hi, Thanks for making this code available, and especially for the pycolmap improvements-- those have been needed for a very long time and the effort will have a big impact.
Have you evaluated this method on Tanks and Temples (or considered doing so) ? The object-centric scenes are a perhaps bit different-- there is perhaps more range of depth and background keypoints have less support (fewer images). If not, do you see more relevance with ETH3D?
I run into the following issue while compilation:

I tried the solution provided in issue 9, still, unresolved.
I tried gcc 8.4.0; gcc 9.4.0; and gcc 5.5.0. Also, I tried AVX2_ENABLED=OFF pip install -e .
and branch fix-parallel-optimizer.
It seems the gcc does not load c++ 14. But I am not sure. Any suggestion will be helpful!!!
I'm trying to refine keypoint from database,and I get core dump during Start feature-metric keypoint adjustment.
The database is built on superpoint and superglue. When the descriptor does not exist in the database, the program will core dump. If the score is empty, this situation will be handle in the Graph::RegisterMatches, what is the cause of this problem?
void Graph::RegisterMatches(std::string imname1, std::string imname2,
size_t* matches, // Nx2
double* similarities, // Nx1
size_t n_matches) {
for (size_t match_idx = 0; match_idx < n_matches; ++match_idx) {
colmap::point2D_t feature_idx1 = matches[2 * match_idx];
colmap::point2D_t feature_idx2 = matches[2 * match_idx + 1];
**double similarity = similarities ? similarities[match_idx] : 1.0;**
FeatureNode* node1 = FindOrCreateNode(imname1, feature_idx1);
FeatureNode* node2 = FindOrCreateNode(imname2, feature_idx2);
AddEdge(node1, node2, similarity);
}
}
When I import the descriptor of superpoint and read it accoording to float32, it still core dump in feature-metric keypoint adjustment. But I use the default uint8 to read the descriptor and the program works fine. I don`t think this is normal, the superpoint descriptor should not be of uint8. What is the cause of this problem?
my code
conf = {
"dense_features": {"use_cache": True,
"max_edge": 1024},
}
refiner = PixSfM(conf=conf)
keypoints, _, _ = refiner.refine_keypoints_from_db(
refined_database,
database,
image_dir,
)
Thanks in advance!

Each time I run a script that calls the matcher, it takes about 20s to load SuperGlue model ("outdoor" weights).
Is there a way to better reuse cache between consecutive runs? Or is it that big in memory?
For instance loading S2DNet checkpoint at /dependencies/pixel-perfect-sfm/pixsfm/features/models/checkpoints/s2dnet_weights.pth. is instantaneous
Many thanks
With all the amazing light field papers coming out in Jan 2022, it would be amazing to pair this work with them. Is the COLMAP plugin code coming soon?
Hey, I encountered this build error as below. It looks like from ceres library. I installed ceres-solver from colmap official website https://colmap.github.io/install.html#build-from-source
Any suggestions? Thanks!

Dear authors,
Really appreciate your efforts to open source this great paper. When I was testing my data, sometimes it can't run through the costmaps generation process. I am using the latest code, here is the log:

Hello,
What is the rationale behind setting the scale of Cauchy loss to 0.25, have you tested different values?
Does this require a calibrated camera or is that inferred?

I printed out the types of the following two parameters, which are <class 'pixsfm._pixsfm._features.FeatureSet_f16'> and <class 'pycolmap.Reconstruction'>.
Is the error due to the wrong type of parameter for reconstruction? how can i solve this problem?
Thanks in advance!

Installation went smoothly for me until the final pixSfM package install via pip. Compilation reached 40%, then returned this error from the glog source packaged with pixSfM:

I am trying to compile it on M1, and creating this issue to put my notes and hopefully guide others, who try to do the same.
There are 2 minor issues, which are fixable with this branch https://github.com/ducha-aiki/pixel-perfect-sfm/tree/M1-macos
The fixable issues are:
#include "sys/sysinfo.h"
and replacing std::chrono::high_resolution_clock
with std::chrono::system_clock
There is a bigger problem, though, with interpolation.h, Evaluate
function. It is a template, and not all possible variants of the templated function are good. GCC ignores this, but not Clang (see https://stackoverflow.com/questions/60180873/template-function-error-in-clang-but-not-gcc)
I will keep updating this issue, as I will be progressing with the compilation.

First of all, thanks for the great work. In the paper and project page the authors mention scaling PixSfM to thousands of images. I'm however running into issues doing the same with datasets ranging in the 1600-3000 image range. Two of the datasets in question can be found at: https://meganerf.cmusatyalab.org/#data
My code looks roughly like:
def main(hparams: Namespace) -> None:
output_path = Path(hparams.output_path)
output_path.mkdir(exist_ok=True, parents=True)
feature_conf = extract_features.confs['superpoint_max']
matcher_conf = match_features.confs['superglue']
images_path = Path(hparams.images_path)
images = sorted(images_path.iterdir())
references = [str(images[i].relative_to(images_path)) for i in range(len(images))]
print(len(references), 'mapping images')
features_path = output_path / 'features.h5'
sfm_pairs_path = output_path / 'pairs-sfm.txt'
matches_path = output_path / 'matches.h5'
extract_features.main(feature_conf, images_path, image_list=references, feature_path=features_path)
pairs_from_gps.main(sfm_pairs_path, images_path, references, 50) # Custom matcher that uses the GPS metadata to match only to the 50 closest pairs
match_features.main(matcher_conf, sfm_pairs_path, features=features_path, matches=matches_path)
sfm = PixSfM(conf={"dense_features": {"use_cache": True}})
ref_dir = output_path / 'ref'
refined, sfm_outputs = sfm.reconstruction(ref_dir, images_path, sfm_pairs_path, features_path, matches_path,
image_list=references)
And in particular the keypoint adjustment phase seems to be taking a very long time. Some examples so far:

The specs for the machines across each of these runs varies a bit, but they're pretty powerful machines (>100GB of ram, dozens of cores, SSD mounts)
I've also tried running PixSfM on an even larger example (matching only against the 20 closest neighbors instead of 50), where keypoint adjustment throws an exception. I've trying reducing the output dim and patch size to no avail:

Any thoughts on what I might be doing wrong, or is a week+ runtime to be expected no matter what? I've gotten suboptimal results on these (drone imagery-related) datasets using even commercial photogrammetry software, so excited to see if I can get better results with your featuremetric approach!
Thanks for the excellent work on Structure from Motion.
One question for the paper:
In the feature extraction, are the features extracted from the pre-trained CNNs? Since I found no loss function to train the CNNs.
I would like to specify the camera model for the reconstruction model. I've seen pycolmap accepts a camera_model
parameter in its import_images
function , which is called by hloc's import_images
. In PixSfM it seems we can pass arguments for hloc's main, but hloc only knows how to manage camera_mode
and not camera_model
.
If I, for instance, would like to create and refine end-to-end a reconstruction with camera model OPENCV
using (using hloc and not colmap). How should I do it?
PS: I could be posting this on hloc's issues, but since using pixsfm is my end goal maybe there is a better way to do it from here, that I'm not seeing.
Thank you!
Everything is fine until final step "pip install -e ."

Did you forget to #include <pybind11/stl.h>
? Or <pybind11/complex.h>,
<pybind11/functional.h>, <pybind11/chrono.h>, etc. Some automatic
conversions are optional and require extra headers to be included
when compiling your pybind11 module.
In refine.hloc a keypoint adjustment step is followed by another reconstruction/triangulation step, which seems to be a triangulate_points/incremental_mapping step of pycolmap.
I don't see a similar complete pipeline for refining when the reconstruction has been done with colmap. It seems to be either keypoint refinement or bundle adjustment in refine_colmap.py
. How should I run bundle adjustment after keypoint refinement when dealing with colmap reconstructions? Should I run a triangulation step manually in between?
Or is this refinded information somewhat passed on through the FeatureManager?
Thank you!
#9 (comment) shows that the compilation fails if AVX2_ENABLED=ON
(default) and the CPU doesn't support AVX2. We should check if __AVX2__
is defined by the compiler, something like #if defined(AVX2_ENABLED) && defined(__AVX2__)
hi,
''dict: Return dict of featuremaps. For format see features/README.md'',but I can not find features/README.md
Thank you for open source this great project.
Recently I read yourpixel-perfect-sfm
paper. I have one question in Eq.(4) which can be described as follows:
I think the key idea of FKA
is to minimize error between matched keypoints from different images in feature-metric domain. I don't know if I am right?
I've tried demo with my own datasets. there are 239 images in datasets. everything works fine until "reconstruction ". My kernel always die in this process. what happened? how to solve this?
I first run a triangulation with Bundle Adjustment on my PixSfM model and then call the QueryLocalizer to localize an image within it.
However, (for specific reasons) I need to do this in two separate Python runs but want to avoid the computational cost of re-extracting the features references at the QueryLocalizer init.
Here's what I do:
reconstruction, outputs = refiner.triangulation(...
...
reconstruction = pycolmap.Reconstruction(model_folder)
feature_manager_path = Path(model_folder) / "s2dnet_featuremaps_sparse.h5"
dense_features = load_features_from_cache(feature_manager_path)
localizer = QueryLocalizer(reconstruction, conf, dense_features=dense_features)
I'd prefer to use the constructor below directly to skip the redundant extraction. But I don't see how to serialize the references I got during triangulation: outputs["BA"]["references"]
QueryLocalizer(conf, reconstruction, references=references)
The bindings don't provide a constructor for "Reference" and its attributes aren't pickable.
Do you have any advice?
Many thanks :)
I have been trying to locate the camera positions for this very challenging dataset. It is a 360 from a sofa with very little texture and views are very sparse. I can only get 10 cameras poses, whether with COLMAP or pixsfm. The successful ones are frontal, while the laterals and rear ones fail.
In other software(COLMAP), I've been trying to constraint the matching only to the images described by a manually made image_pairs.txt
in order to enforce that the images match to the ones I want. I would like to try the same with pixsfm, but even though I see refiner.reconstruction
accepts a list_of_image_pairs
, the matching seems to happen before.
I assume I need to create image pairs with pairs_from_*
but I can't seem to find one that accepts an input text.
I could also find a way to manually create guesstimated priors to correctly initialize optimization, but I don't know of an easy way to do this.
I have other datasets of very shiny objects with which I get into similar problems. What would you recommend doing?
Thank you very much in advance!
First of all, thanks for the great work.I have successfully installed pixsfm, but there is an error when I run the demo in jupyter.

Hi.
I get the following error when testing the demo.ipynb
on another small dataset:
IndexError Traceback (most recent call last)
/tmp/ipykernel_5075/3412010250.py in <cell line: 1>()
----> 1 raw.align_points(refined, max_error=0.005, min_inlier_ratio=0.9, min_overlap=3)

Here's the summary of the reconstruction:
Raw Reconstruction:
num_reg_images = 25
num_cameras = 1
num_points3D = 1262
num_observations = 4097
mean_track_length = 3.24643
mean_observations_per_image = 163.88
mean_reprojection_error = 1.35567
Refined Reconstruction:

num_observations = 4241
mean_track_length = 3.36855
mean_observations_per_image = 176.708
mean_reprojection_error = 1.292
It worked OK on the demo dataset but not on my dataset. What could be the problem here?
I'm trying to refine a Pointcloud extracted using ArCore on my phone, and I get a Segmentation fault error at the end of the triangulation part of PixSfM.
As an input, I provide:

This seems to be the dimention of descriptor. However, I build the latest version of colmap and pycolmap from source. The .db file is generated from the colmap. Moreover, I noticed that the output dimention of descriptor is always 128.
Thanks in advance for your reply!
