Save data in .ply format about livescan3d HOT 6 OPEN

What do you exactly mean by, the ply frames are not registered? Do you mean that you have a single frame for each camera individually, but not the data from all cameras in a single .ply file? In this case, you can just combine the plys from each camera into one frame, with Meshlab for example, as they are still registered, but just output into seperate .plys.

You can also use the LivescanPlayer to open all the bin files, and then check the "Export PLY" button. Now when you play your sequence, it will be exported into the "LiveScanfolder/bin/outPlayer/ folder as .plys

Thanks for clearing this up! Just one more questions, when you talk about registration, can you describe a bit further what you mean? Registration, at least in the computer vision field, often refers to aligning two 3D-models, or pointclouds, that are made from the same scene, but from different viewports/cameras (https://en.wikipedia.org/wiki/Point-set_registration). But you said that you use only one camera, so registration in that sense would not be needed.

Ah I see! Yes that is not a usecase that is covered by LiveScan3D, in this software the cameras are meant to be static. But there are other solutions for this, most prominently KinectFusion (https://www.microsoft.com/en-us/research/wp-content/uploads/2016/02/ismar2011.pdf) which you might want to look into :)
