Hi everyone,
I am trying to perform a 3D reconstruction with an augmented number of keypoints and descriptors, exploiting the same set of images in 3 different color bands.
To do so I have:
Built graph 1 (using band1 images), computed cameraInit and extracted the SIFT features for each image
Built graph 2 (using band2 images), computed cameraInit and extracted the SIFT features for each image
Built graph 3 (using band3 images), computed cameraInit and extracted the SIFT features for each image
For each image, opened its graph3 .feat file and erased its content. Then, set it to the concatenation of band1 and band2 .feat files relative the same image. Repeated this procedure also for the .desc file of each image
Extended graph 3 by adding ImageMatching (Exhaustive) and FeatureMatching (see settings below).
Error
The problem occurs when running the FeatureMatching node of graph 3. Indeed, as soon as that starts, I get:
[2024-02-15 17:18:32,600][WARNING] Downgrade status on node "FeatureMatching_1(1)" from Status.SUBMITTED to Status.NONE
Traceback (most recent call last):

FeatureMatching relevant settings
The settings for the FeatureMatching node (relevant-for the problem) are:
photometricMatchingMethod='ANN_L2',
geometricFilterType='fundamental_matrix'
geometricEstimator='acransac'
It seems like the crash happens as soon as the OPENMP part starts.
Additional info
I have added the print of the returned return code above (ERROR CODE: -11). I looked for that error in all the repository but I was not able to find anything related to returnCode -11.
To check the correctness of the jointed sift.desc and sift.feat features I have tried to append just a few features coming from band2 to band1, in this case everything worked without problems.
Doing those tests, starting with around 3000 features points from band1, I was able to append up to 275 features point from band2 (over the 5000 available in band2) when using ANN_L2 as photometric matching method.
In the same way, I was able to append up to 250 features when using brute-force (BF) as photometric matching method.
After such thresholds, the node crashes as described above (with the same error, independently from the photometric matching method).
I think that the success of the BF matching method confirms the correctness of the jointed sift.desc and sift.feat files.
When working with DSPSIFT (with quality and density set to ultra), the number of keypoints found for band1 is between 20K and 30K, same for band 2, In this case, I am able to concatenate successfully just up to 15point. Then the same crash happens. This highlights that, as the total number of keypoints/features increases, the number of keypoints/features that can be added without causing a crash decreases.
Furthermore, such thresholds seem to change also depending on the total number of images used in the reconstruction.
If anyone can help me or give me some insights toward the possible issue I would really appreciate that.
Thanks in advance!
