Hello Fabio,

Thank you! That was very helpful, we were able to reproduce the issue and are trying to fix the problem now.

Feature Requests / Re: Edit size of 'Show Cameras' rectangles

Hello nik_ska,

For some reason, Shift + Mousewheel stopped working for me on 1.8.2 while using metashape via Remote Desktop on macOS.
Other combinations do work.
Might be some problems with the remote session configuration, as I do not see the reported problem when working on macOS locally.

Is there anything new to say to my question?
No changes yet on that matter. I'll see, if anything could be implemented soon, however, the feature is not demanded that frequently, so it is considered to be of a low priority.

Hell Fabio,

Which products should be generated from the provided dataset? I have aligned cameras, generated the dense point cloud, DEM and orthomosaic, but the report generation called from the Console pane worked.

Maybe you can send the project file from which the report cannot be generated? Also please specify the OS version used.

Hello bassistas,

I also tried to mask out the no-data regions from the laser scans and it solved the black hole issue but as this black area has the same height in the lower part of the image in all of my laser scans is it possible to mask out this automatically from all the scans with a script rather than doing it by hand for every single scan?
You can create the mask for one image manually, export it and them import, applying to all selected scans.

the jpegs are 8bit and the grayscale laser scans are 32bit. Could this be the problem? and what can I do?
And what output do you expect - should the texture be 8-bit or 32-bit?

Hello temetofi,

I would suggest to check the following tutorials related to complete model reconstruction:
https://agisoft.freshdesk.com/support/solutions/articles/31000163388-automatic-masking-from-the-model
https://agisoft.freshdesk.com/support/solutions/articles/31000163268-turntable-capturing-scenario-and-processing-workflow

You should provide sufficient overlap, however, between the image sub-sets for more accurate processing results (for higher accuracy it is suggested to align all the images in the single chunk).

Hello bassistas,

What color range (bit depth) the input photos and laser scans have?

As for the blank spots, I would suggest to mask out no-data regions on the images related to the laser scans prior to the texture generation stage.

Hello Maxim,

Do you need to preserve the exterior orientation parameters for the cameras being copied? And whether you are interested in moving cameras to new (empty) chunk or to the chunk with some processed data?

Bug Reports / Re: Vertical Datum out of range 1.7.1

Hello!

If the problem is also observed in 1.8.3, please share the original project file (re-saved in PSZ format) to support@agisoft.com together with the target coordinate system definition in WKT format (saved to PRJ file) and geoid file used, so that we could reproduce the issue on our side and analyse the problem.

Hello jolle,

Please then send the example of JPG file to support@agisoft.com that we can use to reproduce the issue with XMP meta data.

Hello jolle,

Can you please check, if you are observing that in Metashape 1.8.3?

Добрый день, Ваге Аршакович,

Уточните, пожалуйста, выполнялся ли линейный пролёт для каждого блока (то есть, отсутствует ли поперечное перекрытие), а также на основе каких данных производилась привязка каждого из исходных блоков (координаты центров фотографирования, углы ориентирования камер, опорные точки)?

Если есть возможность, пересохраните исходный проект в PSZ формате и пришлите его на support@agisoft.com. Для уменьшения объёма данных из этого проекта можно удалить карты глубины и плотные облака (затем снова сохранить и отправить).

Bug Reports / Re: Generate Ortho - Big Tiff Error
« on: May 10, 2022, 08:17:02 PM »
Hello Moritz,

I think the problem is caused by incorrect task.image_compression assignment. You need to make an assignment to Metashape.ImageCompression() class variable:
Code: [Select]
compression = Metashape.ImageCompression()
compression.tiff_compression = Metashape.ImageCompression.TiffCompressionNone
compression.jpeg_quality = 99 #will be only used, if TiffCompressionJPEG is selected#
compression.tiff_big = True
compression.tiff_overviews = True
compression.tiff_tiled = True
task.image_compression = compression

Hello Moritz,

Can you please send the log related to the export operation from the processing node? Should be something like that:
Code: [Select]
2022-05-10 12:19:48 Exporting orthomosaic...
2022-05-10 12:19:48 generating 68400 x 82085 raster in 1 x 1 tiles
2022-05-10 12:26:27 Finished processing in 399.705 sec (exit code 1)

Also please specify the input data format: number of channels and bit depth.

Python and Java API / Re: add Folder

Hello Paul,

Creating of MultiPlaneLayout via Python has been described in the following thread (based on two sensor example):
https://www.agisoft.com/forum/index.php?topic=11583.msg51962#msg51962

Code: [Select]
images = [None]*(len(rgb) + len(nir))
images[::2] = rgb
images[1::2] = nir
filegroups = [2]*(len(images)//2)
#images is alternating list of rgb, nir paths
#filegroups defines the multi-camera system groups: [2, 2, 2, ....]

chunk.addPhotos(filenames = images, filegroups = filegroups, layout=Metashape.MultiplaneLayout)

some time ago I have also sent the following example for eight-camera system:


Code: [Select]
camera = [list_of paths_camera1, list_of_paths_camera2, list_of_paths_camera3, list_of_paths_camera4, list_of_paths_camera5, list_of_paths_camera6, list_of_paths_camera7, list_of_paths_camera8]
### list_of_paths_cameraN represent the list of paths for corresponding source folder
​C = len(camera)
images = [None]*(len(camera[0]) + len(camera[1]) + len(camera[2])  + len(camera[3])  + len(camera[4])  + len(camera[5]) + len(camera[6])   + len(camera[7]))
for i in range(C):
    images[i::C] = camera[i]
filegroups = [C]*(len(images)//C)
###images is alternating list of camera[0], camera[1] ... camera[7] paths
###filegroups defines the multi-camera system groups: [8, 8, 8, ....]
chunk.addPhotos(filenames = images, filegroups = filegroups, layout=Metashape.MultiplaneLayout)

Haven't optimized it, though, as we are not getting such requests frequently, but we'll consider publishing universal example in GitHub.

Hello Forester,

There were some examples of Python scripts published on forum, which show how to access the information regarding the tie points. For example:
https://www.agisoft.com/forum/index.php?topic=10730
https://www.agisoft.com/forum/index.php?topic=12781.msg56630#msg56630
So for each tie point you can get its index, and XY coordinates of the tie point projection on every image it is detected on (also valid/invalid tag).

As for the dense cloud - it is generated using a different algorithm, basing on the depth maps, so it is not possible to get similar "relation table" for the dense cloud points.
