Best Way to Add More Points to Dense Cloud?
« on: March 27, 2018, 06:35:15 AM »
I'm trying to get a denser point cloud to work with and I'm wondering how to best go about it.  It's not that i'm trying to get more detail, just that I need more actual points being placed before exporting the point cloud to other software.

Does anyone know how I could do this?  Best way I could think of is just to increase resolution in the source images but that seems wasteful in terms of processing.  Is there anything equal to "Refine Mesh" for dense clouds?  Maybe something like "extrapolate more points from neighbors"?

Hi DTFrontMan,

1) Run 'BUILD DENSE CLOUD' at higher quality settings. Needs more computational power though (RAM & GPU).

2) Generate a (high res) textured mesh, then export as *.OBJ file. Open in CloudCompare and choose 'SAMPLE POINTS ON A MESH'. You can then choose the number of points you like. Details here: http://www.cloudcompare.org/doc/wiki/index.php?title=Mesh%5CSample_points

Hi Sav,

Thanks for the response! 

Currently I'm already using the highest quality setting for the dense cloud that I'm able to, unless you can some how specify something higher than the Ultra High preset. 

The workflow I have going on kind of revolves around avoiding mesh building so I'm hoping to stay away from that if at all possible.  I have processing power to spare...  My main concern is time since I'm going through this process with a whole lot of scans.

Cloud Compare is one I've never heard of so I will definitely look into it and see if there's anything it can do that will help :)
