'OpenCV contrib / Surface Matching / Demo script wrong result / Python / Point Pair Features (PPF)
Installed versions:
opencv-contrib-python 4.5.4.60
opencv-python 4.5.4.58
I try to run the demo python script (ppf_load_match.py) for surface matching in the opencv_contrib. For visualization I open the scene model and the result point cloud in meshlab. I guess both should be aligned correctly. But the alignment seems to be quite off.
Here is a screenshot from meshlab, where you can see the misalignment:
Can you help me? As far as I have seen the alignment with the demo point clouds should be better.
In this video you can see the result I would expect. I haven't made any changes in the demo script.

I found the problem. Just had to change the following line/parameter.
results = detector.match(pcTest, 1.0/40.0, 0.05)
to
results = detector.match(pcTest, 0.5, 0.05)
Have a look into this issue, there it is explained.
