Hello,
I'm building a fairly large model that has been split into chunks and am having issues generating meshes. Project is ~5000 20 Mpix images. Hardware is a 2008 Mac Pro 2.8 octo, 42 GB Ram. Using photoscan 1.3.4 professional version. Project file is saved on an internal drive dedicated for storage, not the system drive.
I aligned all of the images in one chunk and after adding CPs split the project into many chunks using the split code provided by Agisoft. I want a very detailed models and prefer smaller models for use in a visualization tool once the models are complete so I split into ~260 chunks. The dense point cloud processed without any problem. I am now trying to mesh the dense point clouds and am having varying degrees of success. Meshing will start off well and then after processing 2 - 6 chunks it gets stuck and I can leave it over the weekend without any progress. Progress bar just sits on a percentage completed and elapsed time increases. CPU has essentially no load. There does not appear to be any swap occurring and total RAM usage tends to only reach ~20 GB so it doesn't seem like a RAM issue, which is what I have read is the common problem with mesh generation getting stuck. The dense point clouds are 10-20 million points, and I would estimate that there are <50 photos in each bounding box. The process doesn't necessarily fail on the largest point clouds. The only remedy is to force the application to close and restart the machine. If I force close but don't restart the problem happens again right away on the first mesh. After I restart I can process a few more meshes. I have deleted most of the cameras that are not within the bounding box in each chunk as a potential fix, although I did leave some on either end of each chunk. This hasn't made any difference.
Any ideas as to why this is happening would be greatly appreciated. Could chunks that are too small be causing the problem?
