Is it possible to create and save depth maps from the Build Dense Cloud process without going on to construct a dense cloud from the depth maps?
This post references a "Build Depth Map" option in the photo pane context menu:
http://www.agisoft.com/forum/index.php?topic=748.msg3502#msg3502I can't seem to find this option. Has it been removed?
The reason I ask is that my machine seems to be capable of "Reconstructing Geometry" (aka building depth maps) during the Build Dense Cloud process, but then it runs out of memory when it actually goes to make a point cloud from the depth maps. I'm running on linux so the OOM killer kills the process when "accumulating data..." for too many cameras.
If I could build the depth maps separately then I could later construct dense clouds in smaller tiles to avoid running out of memory. This would be much faster than tiling the whole build dense cloud process (i.e. reconstructing geometry + constructing point cloud). I tested this out.
I tried tiling the whole Build Dense Cloud with a small data set on medium quality and it took about 30 minutes. If I start the Build Dense cloud process for the entire project area and cancel it after depth maps have been created then I can reuse the depth maps to tile the dense cloud construction step. This method only takes about 7 minutes, but I have to cancel the Build Dense Cloud process right after it's done constructing depth maps or I risk crashing Photoscan and losing everything. This could be days worth of processing for large projects!
