General / Script Import Points - georferenced [R]
« on: February 05, 2021, 12:38:24 PM »
Hi guys,

i have the following problem:

I import via Python script a (unstructured) E57 point cloud.
works fine, however the [R] Tag is not assigned and therefore the data gets messe up when reexport in Potree file.

when i import manually the data gets assigned with the [R] georeference tag.

console says both imports are the same commands.

Does anyone know how to import via script and get the data georeferenced?

Code: [Select]
chunk.exportPoints(outputpath,source_data=Metashape.DataSource.DenseCloudData,clip_to_boundary=False, binary=True, save_normals=False,save_colors=True, save_classes=False, save_confidence=False, raster_transform=Metashape.RasterTransformType.RasterTransformNone, colors_rgb_8bit=False, comment='', save_comment=False, format=Metashape.PointsFormat.PointsFormatPotree,

Thanks for the script,

Luckily i tested this prior the need for it in a project. ATM i can't test a mixed capture with photos but i will soon.
Thanks Dieter for taking the time cause i think we are trying to achieve the same.

In the end this has to work to be a serious competitor to RC regarding Meshing combined lidar / photogrammetry datasets. :)

Thanks for jumping on board Dieter, i am thinking the same!

The whole Import Laserscan function is useless when it can't utilize the known pre registration. The imported Laserscans are registerted with survey accuracy (sub <1cm) and i don't want to mess this registration up.

Any idea Alexey?

Thanks, one step further...

i see the camera positions and corresponding coordinates + orientation for every scan

I toggle / activate both, the position and orientation check box, when i update i get an error:

"Not enough reference data" ...
Checked the correct coordinate system

i tried the new import laserscan function by importing a E57 file containing 54 Laserscans, exportet from Leica Register 360 (RTC360 data)

I have a problem when finishing the import:

Warning: disabled 54/54 reference records with zero GPS coordinates

The registration is lost.

Thank you,

monitoring the CUDA performance i see 100% workload.

General / Depth map generation performance
« on: December 15, 2020, 09:51:29 AM »

i'm struggling with the depth map generation performance (v 1.6.5),
currently processing a 10k x 20mp corridor mission, splitted into several chunk.
The cpu workload is around 25% I7 8700K and the GPU Quadro RTX 4000 is around 5%, both with peaks up to higher percentages but only 1/10 of processing time.

why is the depth map generation so slow? i feel like it was faster in previous versions. (very high, mild filtering, no tweaks)

General / Re: Long Aerial survey with Gaps
« on: December 05, 2020, 10:48:57 PM »
My question was more related to "best practice",
jeah all images are shot wie a DJIp4RTK with accurate geoposition.

assuming all images were taken on the same day i just wanted to know if the results would be more accurate seperating the non connected chunks :)

General / Long Aerial survey with Gaps
« on: December 05, 2020, 11:15:51 AM »
So quick question about recommondation from the Agisoft Team,

I have a large aerial survey (40km) with 2-3 gaps inbetween where flying was restricted.

Should i align all at once (which is less effort, no splitting etc)
or can i get same results when aligning all at once, even though they are NOT connected.

Thank you in advance :)

General / Potree Export Missing Points
« on: December 02, 2020, 10:05:27 AM »
Hello, any help appreciated:

I'm using the current Agisoft Version 1.6.5

When I'm using the Potree Export Function not all Points are exported, the Output seems to be truncated at a lower Z Limit (Points below a given height are missing)

I tried to duplicate the point cloud, compact the point cloud, export classified, export unclassified, using oversized bounding box, reset bounding box etc.. always the same result. Using a subset of the pointcloud works so i guess theres nothing wrong with my HTML/JS:

I found out that the point number given in the compacted Agisoft Chunk and the exported in the cloud.js does not match:
923.506.005 (Agisoft)
867.068.521 (Potree export cloud.js)

any suggestions?

Thank you in advance for the support

General / Change Coordinate Systems without transformation
« on: November 11, 2020, 01:58:04 PM »
So after i processed the project i recognized that i had the EPSG Code wrong.

The projects coordinate system is consistent so it does not affect the output. I can simple asign a new coordinate system using QGIS ACAD etc..

However i would like to change / update the coordinate system of the generated DEM / Orthophoto within Agisoft without applying any coordinate transformation... Any ideas?

Export and reimport would do the trick but i would like to find another way.

Thanks in advance

Just use Tools - Camera calibration, Export Import function.
I also use this function with my DJI 4 RTK . However the RTK of the DJI isn't that realiable, best you process with PPK. The Z Values can be off for a few centimteters to decimeters. Always use gcp's

Hi, we just bought Agisoft and are really happy, but:
Isn't there any possibility to keep the Orientation paramters? should not be that hard to implement...
