ReconstructMesh: Import dense point cloud

[Sastuba Mark]

Hi openMVS Team,

 

first of all you do a great job.

My question concerns to the mesh reconstruction. We use very large image data sets (10-30k) form underground regions, which often causes memory issues. I know, that some program parts have hidden functions like import “– mesh –file”. I also used this option in order to import a subsampled mesh and to clean regions of false reconstruction and so on. Works perfectly. So is it possible to do the same with the dense point cloud? This would also reduce memory and computational efforts for the following program parts . So is there any chance to run the program ReconstructMesh and link to an external dense point cloud?

 

If not, is it possible to inject or replace a dense point cloud into a .mvs-file using Interface.h ?

 

Thanks you for your help.

 

Best Regards,

Mark Sastuba

Hi Mark,

You can definitely edit the point-cloud before processing farther, but not as easy as the mesh. The reason is that the point-cloud contains additional info, like which images see each point. OpenMVS needs these info so if you alter the point-cloud (mostly crop) make sure to keep this info. Since PLY can not store such info, you need to edit the point-cloud through the interface structure.
