General / Re: Thermal processing workflow for DJI-H20T

« on: December 12, 2024, 12:37:19 PM »

Dear community,

are there any news regarding the possibility of processing thermal images from DJI drones with Metashape?
Some of my customers complain about that this is not possible any more.

It seems like DJI changed the export possibilities of their thermal images and now there is no radiometric data available in the pictures.
Third party software like Metashape is now kept out and only DJI Terra is working.


What is the current status of:

1) Is this behaviour also your experience of the current possibilities?
2) Is rJPG working in up to date Metashape versions?
3) Anyone succeeds in the creation of an radiometric orthomosaic?


Thanks a lot and
Best regards

Alex

Hey Alexey,

are there any news regarding the integration of this feature?

Hello,

Currently drawing plane can be used to create the shapes and markers that lay in that plane.

At the moment the drawing plane cannot be used for setting up the orthomosaic projection plane, however, such option is considered for the next updates.

General / include breaklines (polylines) in meshing process || or useful workaround

« on: April 26, 2021, 06:11:12 PM »

Hello guys 

i'd like to create a mesh (mainly along sidewalk and road surface) while forcing the triangle creation to stick to pre-defined breaklines.

I really would like to do this in Metashape directly, but there doesn't seem to be a way to include breaklines into the meshing process.
And even if it would work in Metashape another issue comes the "rounded edges" "photogrammetric curve"

Two questions related to this:

1) Do you know any improvements of Metashape with regard to this?
2) Do you have any recommendations for any other workflow?

Thanks a lot, guys.

Me neither, Limpopo_River...
I see no different behaviour in the selection - whatever i choose.

Did you find out by now?

Thanks Alexey, thanks Paulo, thanks ALL...   

Once again this forum shows us why Agisoft is the company to go with.
Great developers, great users, open for code/console orders/scripts...

Nice one - looking forward to try out.




Have a good weekend and stay healthy!

... switch the type of the polygonal shape to Outer Boundary...

Hi Alexey,

currently the only option to switch that type to "outer boundary" is in DEM or Ortho, not in other views.
So one needs to generate a DEM and or Ortho first, even though it's not necessary.

Maybe an idea to create a ticket for the developers to implement this menu item in model view?

Greetings

Hey Alexey,

thanks for this workaround   

To clip a mesh with the help of a polygon is a question we were considering right before i wrote.   

Anyway - if someone knows a more straight forward way (even though it might be outside Metashape) i would be very happy to try it.

Hey Metashape friends,

are there any news here?

What are your smart procedures to fulfill this kind of task?
The easier the better - to also maybe have the client measure his areas himself.

Tried a lot already:

+ Metashape (and Viewer) itself (via Pointclouds, Meshes, DEMs)
+ Cloudcompare
+ Potree (would be ok)
+ Meshlab
+ exported 3D PDFs (would be awesome)

None of these options works in an easy way.

Sure, tools like Pix4D cloud, oder ArcGIS Pro can easily do it. Also QGIS can be used for it...
But nothing "simple" to give to the client yet.

What are your latest ideas on that?

Cheers and thx in advance

Bug Reports / Re: Export Orthomosaic => JPG compression fails at native GSD

« on: March 31, 2021, 09:03:46 AM »

Hi Alexey,

i just checked the "tiled" file option and it worked.     

I'd like to search later what this option does, because the funny thing is that the console said: generating 67339x47398 raster in 1x1 tiles.
So after all it still is just 1 tile (file is ~2.2GB) and it doesn't mean to get several tiles like when you use the split option in many tiles.

THX a lot Alexey!

Hello Alexey,

expected filesize will just crack the 2GB border.
Selecting "write BigTIFF file" does not help.

LZW files end up at 4GB

Bug Reports / Export Orthomosaic => JPG compression fails at native GSD

« on: March 30, 2021, 02:34:02 PM »

Dear Support-Team,

export of an Orthomosaic just gave me the following feedback (s. screenshot attached).

I changed some parameters and it seems to be only buggy when exporting into default GSD given by the entire project itself and JPG.

summary:
#  JPG compression does NOT work at default (native) GSD (here: 1.31cm/px)
#  If i change the GSD values just slightly the export works fine
#  LZW compression works
#  JPG works at all other GSDs

Bug Reports / Re: Fails to import pointclouds from ReCap

« on: March 26, 2021, 07:05:26 PM »

Any news on that? 

Having the same issue with LAS (and LAZ) coming from Cloudcompare. Tried exports of standard LAS/LAZ format in CloudCompare and also version 1.3 / 1.4.
Metashape 1.7.2 (12070) 64bit version is crashing instantly not even showing the import dialogue (choose CRS etc.). It happens also in version 1.7.0 build 11637.

Checked on two devices (Desktop 32 core AMD Ryzen; 128GB RAM; Notebook i7 with 64GB RAM) and always the same crashes.

BTW: E57 of exactly the same pointcloud works fine.

Would be great to get this done.

General / Re: Dual RedEdge (Red & Blue) // Band interpretation by Metashape

« on: March 01, 2020, 03:19:51 PM »

SOLVED:

It's mandatory to keep all folders of each camera as they are (including the folders with calibration images).

Then all data needs to be copied to a single main folder.

Add this folder into Metashape => "add folder" in Multicamera option.

Hi Alexey<

it's my own dataset and i can share it with you. Or better just some outtakes because of the data size.

I'm gonna write to you directly, Alexey.
