Always failed to DensifyPointCloud with some default params on openMVS_sample dataset

[CeciliaPYY]

Here is my script,

dataset_out=/dataset/openMVS_sample-master

# Initialize the scene (spherical camera model)
openMVG_main_SfMInit_ImageListing -i $dataset -o $dataset_out/matches -f 3.4

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

# Compute the image matches (notice the angular mode, more adapted for spherical images)
openMVG_main_ComputeMatches -i $dataset_out/matches/sfm_data.json -o $dataset_out/matches  

# Compute of the camera motion and structure of the scene
openMVG_main_IncrementalSfM -i $dataset_out/matches/sfm_data.json -m $dataset_out/matches -o $dataset_out/reconstruction

#
# MVS (optional)
#


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

And here is my DensifyPointCloud-2005241555208B4734.log

Could anyone help me to find out why???

[CeciliaPYY]

However, I got quite good result with COLMAP

[cdcseacave]

the SfM reconstruction (the input to MVS) is not correct

Sorry to interrupt, but what do you mean by reconstruction is not correct, I quite follow the MvgMvsPipeline.py 's SEQUENTIAL pipeline.

pls check in Viewer

[CeciliaPYY]

I happened to use docker due to some building errors, which means I didn't use Viewer but CCViewer instead. I also tried to run tutorial_demo.py on my dataset, which from my point of view, two datasets share same attributes, such as large overlap between images, however nothing come out under reconstruction_sequential directory, and the result under reconstruction_global is very strange.
