Agisoft stucks when calculating the tiled model

[Suesseng]

Hello There,

usually when i m calculating the tiled model i just take the preferences as they come from agisoft
and when i start calculating it just goes fine.

I did this with models with up to 80 000 000 points in the dense point cloud without a problem.

Now i have a model (about 6 ooo ooo points in the dense point cloud) an when i start calculating the tiled model
the Computer stucks because all 16 GB memory is used....

I already changed the pixelsize from 0.0275146 (this is proposed by agisoft) to 2.75146 but again al my memory is used.

Could you help me out, i dont no how to solve the problem because usually it worked out just fine.

Thanks alot,

Riko

Hello Rico,

Do you have the processing log related to the failed operation?

How many images are there in the project and what's their resolution?

Hello,

there are 46 Cameras with a resolution of 4896x3672

Thanks for your help,

Hello Riko,

"bad allocation" error means that there's not enough memory to complete the operation.

I can suggest to install latest release version of 1.4 (1.4.3 build 6488) and enable "Fine level task distribution" option in the Network Preferences tab for Build Tiled Model operation, then PhotoScan will process the task in smaller sub-jobs, thus lower amount of RAM would be required.
