Agisoft PhotoScan 1.3.0 pre-release

[bisenberger]

Hi Alexy,
I built a project from scratch with 1.3 build 3620. Here are the steps:
Added cameras
Aligned images
Built mesh with sparse cloud
Placed markers
Renamed markers
Set project to UTM zone 14, WGS84
Imported control points
Ran optimize
Build dense cloud
Ran auto classify ground points
Selected points and reclassified
Saved project (PSX)

When I saved the project the points I manually reclassified reverted back to what they were previously.

Also worth noting, the mesh created from the sparse cloud appeared black, top and bottom.

Hello,

I have next error "RuntimeError: Grid size overflow" on call BuildOrthomosaic() 
I use with PhotoScan 1.3 linux 64b

Here is my code:

Code: [Select]

...
doc = PhotoScan.app.document
doc.open(project_path)
chunk = PhotoScan.app.document.addChunk()
chunk.addPhotos(images_list)
camera = chunk.cameras[0]
chunk.loadReference(out_csv, format=PhotoScan.ReferenceFormatCSV, columns="nxyzabc", delimiter=",", group_delimiters=False, skip_rows=0)
chunk.crs = PhotoScan.CoordinateSystem("EPSG::4326")
chunk.matchPhotos(accuracy=PhotoScan.HighAccuracy, preselection=PhotoScan.GenericPreselection)
chunk.alignCameras()
chunk.buildDenseCloud(quality=PhotoScan.MediumQuality)
chunk.buildModel(surface=PhotoScan.Arbitrary, interpolation=PhotoScan.EnabledInterpolation)
chunk.buildUV(mapping=PhotoScan.GenericMapping)
chunk.buildTexture(blending=PhotoScan.MosaicBlending, size=4096)
chunk.buildOrthomosaic(surface=PhotoScan.ModelData, blending=PhotoScan.MosaicBlending, color_correction=False)
...


Full text of error:

I have read about this error in context of the wrong sequence of lat/lng here
http://www.agisoft.com/forum/index.php?topic=6027.0

I check reversed value of lat/lng and orthomap was build with no error but with wrong coordinates.

There is log from GUI console:

Hello bisenberger,

We will try to reproduce the issue, although quick tests worked as expected.

[Alexey Pasumansky]

Hello andrey.d,

Have you tried to build orthomosaic basing on the same data but using the GUI option? Also in the model view do you see that the coordinate axis orientation is correct?

[bisenberger]

Hi Alexey,
Here are some screen grabs showing some of the issues I'm having.

This one shoes some strange color artifacts on the dense point cloud.
Note that one of the graphic cards I'm using has changed. Previously I had two AMD cards. I replaced the slower one with a faster nVIDIA card.


This shows a mesh created from a sparse point cloud. It is completely black.


This one shows an area where I manually reclassified some points.


and this shows the results of saving the project immediately after reclassifying the points.



nVIDIA driver version 376.33
AMD Radeon driver version 16.12.2

Besides swapping a graphic card I recently added another 32GB of ram to my system.

[Alexey Pasumansky]

Hello bisenberger,

And which graphic card is used as OpenGL rendering device? Is the behavior the same if you switch to another card?

Also can you try to remove some part of the dense cloud manually and save - would the removed part be restored after saving?

[bisenberger]

Hi Alexy,
By rendering device, do mean which card is the monitor plugged into?

I deleted a patch from the dense point cloud and saved the project. The points came back when I saved.

[Alexey Pasumansky]

Hello bisenberger,

I think we were able to reproduce the issue with PSZ file format.

[bisenberger]

Hello bisenberger,

I think we were able to reproduce the issue with PSZ file format.

The format I'm using is PSX.


If I open the file up in version 1.2.6 the colors for the point cloud are really messed up.

[Alexey Pasumansky]

Hello bisenberger,

At the moment we weren't able to reproduce the problem with PSX, but there's an issue like you've described with PSZ.

As for the colors, the internal representation of the dense cloud has been changed in 1.3 to allow multispectral and HDR colors for the point clouds, so if you are opening PSX project in the older version, it may be interpreted incorrectly. The compatible file format for the version 1.2 is only PSZ in Save As dialog.

[bisenberger]

Thanks for the info Alexey. Let me know if there is anything I can do to help track down the issue.

[mattcalavera]

Hello Matt,

We have requested the sample dataset, but it seems that it's no longer needed, as we were able to reproduce the problem on multi-GPU setup.
Could you please also check the alignment on your system with only one of two GPU devices one, just to be sure that it works properly in your case?

Alexey Thanks, i'll check and let you know

Hello andrey.d,

Have you tried to build orthomosaic basing on the same data but using the GUI option? Also in the model view do you see that the coordinate axis orientation is correct?

Hello Alexey,

You advise me to try test my dataset in GUI mode.
A did it and have the similar error: Grid size overflow
And again if I change lat and long the map was built with no error but with wrong coordinates (placed in Saudi Arabia instead Bulgaria).

Please, find  csv-files with coordinates attached. And psz-file with the project at this link  https://drive.google.com/open?id=0B5NgaXpGOtOUQjlmT01TYllFU3M

There seems to be a bug when importing cameras from xml, setting the key and tie points always ignores the settings and defaults to 0,0.   

[Alexey Pasumansky]

Hello andrey.d,

For me it looks like the camera orientation angles loaded to the Reference pane are incorrect - so the model orientation in space in also incorrect. I've input very large number as "camera accuracy (deg)" to the Reference pane settings and then Updated the Reference pane - the orientation of the model after that looked valid.
