Feature Requests / A tool to "link" together aligned chunks
« on: March 17, 2016, 07:06:04 PM »
Hello everyone,
if I have one chunk with known coordinates markers, and one or more other chunks aligned to the reference one with point based alignment method, if I replace the markers' coordinates with those of another local coord. system, I need to realign all the other chunks to have also these in the new reference system. That's frustrating  :-\. May you implement something to "link" the selected aligned chunks?

Hello,
I've just installed 1.2.0 version. I'm trying to manually editing the dense cloud but the behaviour is really different from the manual editing applyed to the sparse cloud or to the mesh.

I start to explain.

If i want to edit manually a part of the mesh, I usually work on just a piece of it per time so I can avoid memory lack when I rotate, zoom or pan the model. I usually select a part of the mesh, I CROP the selection and then I start to remove from the selected part the unwanted mesh parts with the key DELETE SELECTION. When I've finihed, I just use the UNDO command until I have again the entire model, but all the previously unwanted part keep SELECTED: then I just delete such selected part and I start to edit another piece.

The same thing cannot be applied on the dense cloud unfortuantely: indeed when I use the key UNDO as before explained to go back to the entire dense cloud, photoscan select the entire cropped part at the beginning, and so I loose my editing.

May you correct such issue?

Thanks
Regards

Bug Reports / Build orthomosaic issue in cluster mode
« on: November 21, 2015, 04:15:52 PM »
Hello,
I'was just testing now the new photoscan version 1.2.0 (Released, not pre-release). When I start the Build Orthomosaic process in local mode the process is correctly completed. The same process report error when used cluster mode, cannot open Filename.dat in the orthomosaic specific folder.
Attached the reported issue.

Thanks
Regards

Bug Reports / RAM Memory issue when processing in Cluster Mode
« on: July 21, 2015, 07:20:09 PM »
Hello everyone,
I usually process huge datasets with photoscan pro in clustering mode by using three PC connected on the same network, but I have some consideration to do based on the problems I'm finding by using it, and I would like to know your opinions and experiences.

First of all I need to clarify my cluster network configuration: three workstations with different RAM memory size installed on, as 2 PC have 16 GB, the 3rd one has 128 GB installed on.

When you process a dataset in this mode, as you know, photoscan splits the process in several "packets" and every node of the network processes a single packet and starts to process the next one when the actual packet has been completed.

Now my problem:
I'm processing, as above described, a huge dataset (in my case I'm building a dense cloud in High resolution) but when the "Filtering data" step starts (after the depth maps have been calculated), the nodes with less memory (in my case the two PC's with 16GB) procede to process the packets very slow, as the progress value stays on the same value for a lot of time. By checking the TASK MANAGER on these two machines, I've realized I've NO free ram, as totaly occupied by photoscan (the process is not in a "not responding" status, it's just like a "congestion" of the pc).

1st  question:
how photoscan decides to split the project is packets? I mean...how photoscan decide how many packets must be done? By checking the ram memory size of the nodes of the cluster?

2nd question:
If photoscan checks the ram memory size, it should adapt the packet size to the nodes' ram memory. Isn't it?
Anyhow, believing the packets are equal each other, whit ram size value is used? The lowest one? The Biggest one?

Consideration:
What I think, but I would like a confirm (maybe from agisoft itself) is that the single packet size is computed based on the first node that has been connected to the server, and that could explain the fact that I have two PC freezed, while the PC with 128GB proceedes without problems (in my case the first machine I've connected to the server is the biggest one). Anyhow, this behaviour compromise the conclusion in a reasonable time of the whole process, as there will be always two machine almost freezed on two packets, and even if the biggest one will process all the remaining packets, the process itself will be completed very slowly. The only solution is to disconnect the freezed nodes and to let the biggest pc process the remaining packets.
Could some confirm this thesis?

Thank you.

Bug Reports / Batch Process while exporting models files
« on: March 17, 2015, 03:02:47 PM »
Hello,
I'd like to report a problem related to the export of models in batch.
Indeed, when I export the mesh of all the chunks, the software start to export the first file (I've tried for WRL file format) but once completed it starts to export the next one by overwriting the first one.

Could you please correct?
Thank you.

Bug Reports / Poor Dense Cloud quality when clustering mode is involved
« on: February 08, 2015, 08:00:20 PM »
Hello,
I'm having serious issues with a photoscan project when I perform the dense cloud process: after several tests I've been able to realize that the problem is related to the use of Clustering processing mode.
By processing the same project, with all the photos aligned, with a single PC, there isn't any problem and the dense cloud is perfect, while if I process the same project by using a cluster, the dense cloud is extremely noisy.
I was wondering there was a network problem, but I've tryed to perform dense cloud with just one computer by configuring it as Server, Node and Client at the same time. Nothing change, the dense cloud is really noisy, so no network problem.
I've upgraded to Photoscan PRO 1.1.2  and the graphic drivers are the last available, but nothing changes.
Does someone else has the same problem??
Thanks.
