General / Re: Is it possible to merge tiled model ?
« on: June 07, 2021, 02:42:17 PM »
Hello Cyril,

Currently it is only possible to merge the tiled model during the tiled model generation operation, providing that another tiled model exists in the project. In this case in Build Tiled Model dialog it would be possible to use "merge tiled models" option and select the "source" tiled model, which would be merged to the newly created model, keeping the same tiling as in that source model.

Hello artp,

According to the provided project - all the used values in the sixth orthomosaic channel (related to LWIR band) are 65535.

I'll try to reproduce the problem on another project, following the same steps as in your workflow.

Hello tom_rc33,

The coordinate information for cameras and markers from the Reference will be considered for optimization and georeferencing process only for those items that are checked on in the pane.

And you need to have at least three reference points that do not lay on the same line (cameras and/or markers) to georeference the model - using only one reference points will not work.

You can play with the measurement accuracy values for the cameras and markers, if one is preferred over others, in order to increase the GCP  weight in georeferencing process.

Hello Rollo,

For near-vertical (nadir) aerial surveys it is recommended to use Generic + Reference (source) preselection options.

Hello Emanuele1234,

you can do the following, assuming that your list is list_of_vectors:
Code: [Select]
list_of_tuples = [(v.x, v.y) for v in list_of_vectors]

Hello andre.fak,

Do you observe large positioning errors on markers (GCPs) in the Reference pane of Metashape window?

Hello TarickTDS,

Which version of Metashape you are using?

I've tried to reproduce it in 1.7.3 version on random model, but it worked as expected.

Hello Andy,

Usually we do not recommend to align more than 70 - 90 thousands of images in the single block (assuming that almost default parameters are used), as memory consumption and expected processing time rise dramatically at some point, due to the algorithm specifics.
I would expect more reasonable memory consumption for 10 000, 30 000, 50 000 image projects.

Instead of the outdated PDF that you are referring to, we have published the article in the Knowledge base which represent some information about memory consumption and processing time for common workflow operations for aerial and close range project examples:

Hello artp,

Maybe you can save a small copy of the project, where only textured mesh is present (imported mesh that is textured by Altum camera with the raster transform applied), save it in PSZ format and send to

Hello drirun,

Please try to create RLM_ROAM environment variable with value set to 5, while computer is connected to the floating license server and then check, if Metashape works in the activated mode after disconnecting from the license server network.

Hello Resourceful,

Do you observe similar behavior for any project (orthomosaic and DEM)? In case the problem is specific for certain dataset, please send the PDF report from that project to

If possible, please specify the OS version that you are using, the dimensions of the DEM for upload (total size, tile size).

Upd: seems that I was able to reproduce similar problem, when trying to upload DEM with about 200k x 200k pixel dimensions. We'll investigate the problem further on our side, as we've got a way to reproduce it. Smaller DEM, as I have mentioned before, was uploaded successfully.

Hello cyrilp,

Which Threadripper model you are considering?

As for the video memory issues, which steps you are referring to and whether they are still observed in 1.7.3 release version?

General / Re: How to update tiled model coordinates ?
« on: June 02, 2021, 04:03:58 PM »
Hello cyrilp,

The tiled model referencing should be updated together with the point cloud and mesh, unless you have Lock Transform option enabled for the tiled model in the Workspace pane.

Hello Andrea,

For testing purposes you can use Tools Menu -> Run script command to start the modified script.

Hello Andrea,

"Test_Pro" is the camera name that is recorded in XMP of the images from this camera. In Metashape XMP has priority over EXIF data.

It seems to be an issue of DJI firmware, so if you have any contact in DJI, you can let them know, that the camera name is incorrectly kept in XMP meta data.

I've seen recently similar problems for this camera/drone coming from other users.
