hi, I have 5 panoramic images -- download, then I use openMVG to generate scene.mvs. refer https://github.com/openMVG/Image_datasets/tree/master/360_dataset my shell script:

dataset="/Users/jiang/Desktop/qwe/images"
dataset_out="/Users/jiang/Desktop/qwe/out"

# Initialize the scene (spherical camera model)
printf "1. Intrinsics analysis\n"
./openMVG_main_SfMInit_ImageListing -i $dataset -o $dataset_out/matches -f 1 -c 7

# Compute of the features (you can add -n <THREAD_COUNT> to be faster)
printf "2. Compute features\n"
./openMVG_main_ComputeFeatures -i $dataset_out/matches/sfm_data.json -o $dataset_out/matches -p HIGH

# Compute the image matches (notice the angular mode, more adapted for spherical images)
printf "3. Compute matches\n"
./openMVG_main_ComputeMatches -i $dataset_out/matches/sfm_data.json -o $dataset_out/matches -g a

# Compute of the camera motion and structure of the scene
# printf "4. Do Global reconstruction"
# ./openMVG_main_GlobalSfM -i $dataset_out/matches/sfm_data.json -m $dataset_out/matches -o $dataset_out/reconstruction
printf "4. Do Sequential/Incremental reconstruction\n"
./openMVG_main_IncrementalSfM -i $dataset_out/matches/sfm_data.json -m $dataset_out/matches -o $dataset_out/reconstruction

#
# MVS (optional)
#
printf "5. MVS (optional) -----------------------------------\n\n\n"
# Export the scene to a cubic scene (there is no open source MVS tool that consider spherical images as input)
# - each sphere is exported as 6 pinholes images
#
./openMVG_main_openMVGSpherical2Cubic -i $dataset_out/reconstruction/sfm_data.bin -o $dataset_out/reconstruction/cubic

# Convert the scene from OpenMVG to OpenMVS data format
./openMVG_main_openMVG2openMVS -i $dataset_out/reconstruction/cubic/sfm_data_perspective.bin -o $dataset_out/reconstruction/cubic/scene.mvs -d $dataset_out/reconstruction/cubic/openmvs_images

I think it creates scene_dense.mvs that are ineffective

my question

I've seen this before, and your answer is too few registration points, but my goal is to generate scene_dense_mesh_texture. ply with only a few possible spots, even if only one frame is generated.

@pmoulon How do I use openMVG to set parameters and increase the error to increase the number of production points, And @cdcseacave how to set parameters when using openMVS to generate the densify point cloud even when receiving fewer registration points. Thank you very much

cdcseacave commented 5 years ago

The low number of 3d points in the sparse point-cloud is not helping, but I think there might be also something not right with the OpenMVG2OpenMVS exporter for spherical image scenes, or the spherical to cube exporter. I for sure never tested this pipeline, I do not know if @pmoulon did.

pmoulon commented 5 years ago

General info (as you said):

In order to run OpenMVS on OpenMVG's spherical scene you first need to convert the Spherical SfM scene to a cubic scene (available in the develop branch of OpenMVG). See https://github.com/openMVG/openMVG/issues/1505

Convert You scene to cubic main_openMVGSpherical2Cubic
Convert the cubic scene to OpenMVS or PMVS
Run your MVS tool -> Thank you for sharing your script with the community!

In your case, the scene seems featureless (white walls), this is not helping for MVS.

I would advise you to run OpenMVG SfM with more points per image

zhigangjiang commented 5 years ago

Thank you for your reply. I took 43 panoramas in that room today.
The resulting sparse point cloud： Screen Shot 2019-06-14 at 5 29 35 PM I think that's enough points, then run DensifyPointCloud:

@pmoulon I ran the dataset you provided and got the desired results(I resize 1024*512 to show that low resolution can be generated): Screen Shot 2019-06-14 at 5 46 05 PM so the build of openmvg and openmvs are normal execute.

In order to get more points, I modified some parameters: [-r|--ratio] Distance ratio to discard non meaningful matches Using 0.6 is more restrictive => provides less false positive. So larger value produces more points ?

./openMVG_main_ComputeMatches -i $dataset_out/matches/ sfm_data.json-o $dataset_out/matches -g a-r 1

-r 1 is error:

4. Do Sequential/Incremental reconstruction

so set it smaller ? -r 0.6

./openMVG_main_ComputeMatches -i $dataset_out/matches/ sfm_data.json-o $dataset_out/matches -g a-r 0.6

it worked, same as before cloud_and_poses.ply: Screen Shot 2019-06-14 at 6 10 03 PM scene_dense.ply: Screen Shot 2019-06-14 at 6 14 03 PM final result: Screen Shot 2019-06-14 at 6 08 14 PM I want to get the outline of the room, the details are not so important. @cdcseacave I don't understand why so many points are removed when I run DensifyPointCloud I try set --number-views 0 or --number-views-fuse 1 but it didn't have the desired effect. How do I set it ？

Finally, I set the parameters like this

./openMVG_main_ComputeFeatures -i $dataset_out/matches/sfm_data.json -o $dataset_out/matches -p ULTRA
./openMVG_main_ComputeMatches -i $dataset_out/matches/sfm_data.json -o $dataset_out/matches -g a -r 0.8

get scene_dense_mesh_texture.ply: Screen Shot 2019-06-14 at 6 28 24 PM 👍👍 In fact, it's only half the room, it doesn't work very well, and using -p ULTRA takes a lot of time. I think it can be optimized. Sorry to ask so many questions, thank you for your contribution

Your scene is very low texture, and hard to reconstruct using SfM. You can try:

projecting some lights pattern on the walls
use a very high resolution camera that generate high quality images

But even if you fix all the above, I still think there is something not optimal in the pipeline. The well textured room from Pierre does not reconstruct very well either. I'm sorry, but I do not have time right now to look into this.

Thank you for your suggestion, I will try it.
