For some reason, RS does not display ALL the points actually present in my sparse point cloud (tie points) generated after the Alignment stage. There are about 85,000 points in total.
However, if I export the point cloud using ‘Export Sparse Point Cloud as PLY’ and then open it in Blender, I can clearly see all the points there. I have attached screenshots of the point cloud for reference.
Also, I tried to find a way to increase the point size (I remember this was possible before), but now I cannot find where this setting is located. I wanted to check if the issue is simply due to the points being too small.
Thanx for reply, David.
But, as I mentioned on my original message - my point cloud is very simple - just about 85k points. So its not clear what I can change in Rendering settings to make any impact on my case
UPD:
just in case I will add my source images so anyone can check my issue themselves.
to replicate it - just put these images in RS, then make “Align Images” process (it will take about 10 sec) then Worlflow->Export->Sparse point cloud as ply (in settings set "export ascii=false)
Then import result PLY in Blender (or any other viewer) and you will see how different point cloud IS compared to RS.
There is also a restriction in the viewport that filters out tie points that are “ill-conditioned/unreliable points”. Basically, the export of a sparse point cloud is exporting the whole point cloud; that’s the reason you can see more points in Blender. As a proof of concept, you try exporting COLMAP with the option “Exclude unreliable tie points” with on/off and then visualise it any COLMAP viewer.
