Agisoft PhotoScan 1.2.0 pre-release

Hello,

Can you specify exact format for importing tiff DEM please? 16 bit or 32 bit? My experience is that Agisoft has lot of crashes after DEM import.

Best,
Jakub

Hello dcm39,

On a different note, on one of the machines, I'm getting the following error (in launching the client):
Cannot mix incompatible Qt library (version 0x40804) with this library (version 0x40807)

I can get rid of it by overriding the photoscan.sh script to force it to use the system libraries instead of the ones provided. However, the system libraries are older and don't work properly with the 3d display (only get markers, not pointcloud). It seems that although the Qt libraries are provided, it is using a system one as well?

I'm using Mageia linux, 64-bit. Running ldd | grep -i qt shows that it is correctly referencing the 4 libraries in the install directory.
Any suggestions?

The problem may be related to the usage of Qt plugins from another Qt version. Also the problem could be caused due to the windows manager using Qt.

Unfortunately, the problem is not common and we cannot suggest good solution for the problem at the moment.

Another network processing problem. I'm distributing processing onto two servers, one of which has a GPU, the other does not. I have only a single user profile on our system.
Starting the node, the one with the GPU gets the --opencl_gpu_mask 1 and the node without gets --opencl_gpu_mask 0.

With processing running (fine distribution to both machines), we get:
[CPU] estimating 238x257x96 disparity using 238x257x8u tiles, offset -52
opencl not found
processing job: BuildDenseCloud
timings: rectify: 0.015485 disparity: 0.08769 borders: 0.01633 filter: 0.02417 fill: 1e-06
[CPU] estimating 242x251x96 disparity using 242x251x8u tiles, offset -53
timings: rectify: 0.01503 disparity: 0.078616 borders: 0.009516 filter: 0.009682 fill: 0

ie. "opencl not found" errors, only on the machine without a graphics card. These errors flood back to the server, but they don't seem to affect the processing.
I suspect that this is to do with the user profile. There seems to be interference between instances run from the same user profile.

OpenCL error may appear only if opencl_gpu_mask is not set to zero.

Computer locks up when attempting to trim a mesh with 52 million faces.
No problems creating the mesh or decimating down to 5 million faces.

PhotoScan Standard Edition Version 1.2.0 build 2158 (64bit)
Windows 7
Intel i7-3770 3.40 GHz
16GB RAM
AMD Radeon HD 7770 GPU 2GB memory
AMD driver 14.501.1003.0

Added:

Updated graphics driver to latest version from AMD website 15.200.1062.1004

With the large mesh the system appears to be moving data in and out of C drive which is a 100 GB SSD with 18.3 GB free. System has two other large internal drives, both of which have lots of free space.

Trimming the decimated 5 million face mesh works fine.

Hello David,

2 GB video RAM may not be enough for visualization of high-poly models in solid/textured views. Shaded option is less resource demanding. Additionally I can suggest to switch "Enable VBO support" option in the Preferences window.
Which view option you are using?

Hello,
I encountered a problem with the last beta release, photoscan freezes (not responding during about thirty seconds) every minute regardless the action I do.
May be this is related with the lag observed (and reported ) before, but now it is really impossible to work with such issue.
All my pc is up to date (windows seven recently updated, graphic drivers too). The projects I tested are not big and during the freezes, the processor is not used. Do you have an idea?
Thanks.
Pascal

PS: after a quick reprocessing of partial set of photos no freeze was observed for the moment, does this mean that all the old calculation are to be reprocessed if some additional work is needed? I will try to re-launch a problematic chunk with the last Photoscan version, and I will let you know ....

Hello Pascal,

Do you have similar issues on the same projects with the version 1.1.6?
Recalculation of the old projects is not required, so I can suggest to check the system with anti-virus just for case.

[Alexey Pasumansky]

Hi, is there (or will there be) the possibility to export polylines or polygones as dxf?
shapefiles are OK for maps or "top-down" view but they are not workable if you work for example with wall facades or buildings.
Thanks,
G.

Hello giancan,

We'll try to add DXF support and also add planar projection option for DEM generation.

Hello Jakub,

DEM should be in 32-bit floating point format TIFF file.

If you have any sample file that crashes application regularly, please send it to support@agisoft.com.

Alexei,

for the DEM import crash problem, I get it whenever I try to import a geotiff DEM 32 bit floating point in strip orientation format.

But if I try to impotrt a DEM in Tiff tiled orientation format, I have no problem....

Thanks,

Hello,

Great job, this new version brings full of good things !

About seamlines, is it possible to export shape (or dwg, dxf...) ?
Customers sometimes requests this.

Thanks
Maxime

Hello Pap1956,

Thanks for the information, we've tracked the cause of the issue and will fix it asap.

Hello Maxime,

Thank you for the suggestion. We'll probably implemet it in one of the upcoming 1.2 updates.

[Helimax]

Great !

Hello

We are using network computation with 3 computers... But whenever we want to connect the 3rd computer this message shows up:

registration failed: Key rejected

Is it possible that we have used the same key twice for our installations?

Hi, I have the same problem.
In the last months i worked with a lot nodes using the same license for all computers. Now i'm trying to use the last version of PS but it works for only one node. For the others, it doesn't accept the license.

[Alexey Pasumansky]

Hello mrlc,

According to the license agreement PhotoScan license keys are node-locked, so on every node/computer separate license key is required for PhotoScan activation.

Dear Agisoft,
it seems that every time I try to export a panorama, the computer freezes (after around 15seconds) and it doesn't seem to recover even after some hours... so I have to hard reset. In the previous version, it was taking quite some time but i didn't experience any freezing.
Is there any settings to check or is it just a bug of this pre-release?
Also it seems that psx files create a number of folder and subfolder, differently from psz where all was contained in a zip archive. It seems also that some operation are not available with the psz format, so I am obliged to save my files in psx... with all their folders. Are you planning to leave this file format as it is now (with folders outside the file) or will you allow the user to choose whether s/he wants to create single-file psx or folders-psx?
Thanks

[Alexey Pasumansky]

Hello giancan,

In the Save As dialog you can decide between PSZ and PSX formats. The latter one is required for DEM/Orthomosaic/Tiled model generation and also for network processing.

As for the panorama issue, please specify the number and resolution of the images in the Camera Station, the export resolution of the panorama and RAM available on the computer.
