General / Licence on New PC
« on: July 13, 2022, 10:14:32 AM »


The former PC I used crashed so I had to install my OS on a new one.
When I tried to activate Metashape with my licence key, it says that the "Activation key is already in use".
But as my old PC has crashed I can not deactivate the key.

How can I use my licence key ?

Thank you in advance.

I had the same problem.
The solution worked for me.

Bug Reports / Dark orthophotography export
« on: January 25, 2021, 12:16:11 PM »


I use Metashape V1.6.5 b 11249

After exporting othophotographies in tiff format, they now appear very darker oppenned in my SIG software (QGIS 3.16).
The export in jpg format is ok. The exposition remains the same as in Metashape.

Should I correct my ortho before export ?

Thank you in advance for your answer.


Bug Reports / Re: GCP problem

After a series of new chunks processed, I can confirm that there is problem.

Working on placing GCP on processed mesh.
After a period of time placing points, new points created start to have a huge error.
Just need a restart of the software to continue placing the points at the same places without error...

I found a solution to my problem (restart the software) but I think it is not a clean solution...

Thank you for your answer.

But I do not understand why on the same chunk :
- Add a marker on a photo 01
- Check the place of the marker on the next photo : the marker is not at the right place
- Check the marker on the mesh : the marker is not at the right place
- save
- close the software
- open the software
- load the project
- Add a new marker at the excat same place on the same photo 01
- Check the place of the marker on the next photo : the marker is at the right place
- Check the marker on the mesh : the marker is at the right place

It is the same chunk, same photo, same place, why the result change and why it is good after just a reboot of the soft ?

Best regards,


Bug Reports / GCP problem

I am currently using the Metashape version 1.5.2 build 7838 (64bits).

Working on placing GCP on photos after alignment, dense cloud and meshing done.

It works well until a point where the pix error become huge (>100) and the referenced points are placed at wrong places.

I have to restart the software and open the project I was working on to continue the referencing.

The previous wrong points are still wrong but I can creat new points that are good.

The same chunks with faulse points can be referenced with no porblem until the problem appaer aggain (arround 10 gcp placed)...

For exemple (file attached) the same gcp marked during the problem and after a restart.



General / Re: 8 bits Orthomosaic

I have found a solution.
I just choose to export the jpg orthomosaic instead of the tiff file.



General / 8 bits Orthomosaic
« on: November 14, 2018, 04:31:16 PM »


I have just figured out that photoscan can now produce 16 bits orthomosaic.
I can not find in the changelog when the update happened...

My problem is that the software I use once the orthomosaic exported (QGIS) do not manage 16bit rasters...

In fact I have 16bit ortho because I treat 16bit raw photos, so I can produce 8bit ortho using tiff developped from the raw files...

I wonder if there is an easier way to export 8bit orthomosaic without having to redo all the processing steps I have already done with my raw files sets ?

Thank you in advance,

Best regards,

Thank you for your answer.
It seems indeed more effective.
I will try it right now.


Feature Requests / Orthomosaic references
« on: April 17, 2018, 01:09:55 PM »

It would be very helpful to have the references of the photo use for each part of mosaic of orthomosaic.

On orthomosaics there are sometimes parts that are blurry because the photo chosen by the software is blurry.
In this case I chose to mask the blurry part of the photo used then the software chose another photo for the orthomosaic.
But when there are a lot of photos, it is difficult to find the right photo to mask.
It would be helpfull to have the reference of the photo used for the mosaic parts.
Here an example of one of my orthomosaic showing the seamlines of the differents parts used. A right clic on the blurry part could reveals the reference of the photo used.

What do you think of that idea ?

Best regards,


Feature Requests / Re: Markers estimated coordinates export

Thank you for your reply.
This is great !

I will never found this trick alone.  ;)
I will have to keep it somewhere.

Thank you again.



Feature Requests / Markers estimated coordinates export
« on: September 21, 2017, 11:13:29 AM »


It would be interesting to be able to export the estimated coordinates of markers even when the chunk is not georeferenced yet.

In my case, I could use then to orientate (level my chunk thank to the 3 point level tool in cloud compare).
Then I can use my new leveled markers coordinates to level my chunk back in photoscan.

As the estimate coordinates are not available yet, I use the draw point tool to create point shapes on my markers, then export the dxf to do my leveling stuff then come back in photoscan.

I manage to do the job but it would be more accurate to use the markers that are more rigorously placed.

What do you think ?



Bug Reports / Re: Limited import of GCP
« on: June 22, 2017, 03:02:30 PM »

Thank you for your quick answer.

I had a problem with the name of my gcp (missing a ".") so I freaked out when the points were not imported...

Finally, I never noticed that the dialog was limited before, so it pushed me in my error...

Once again thank you very much.



Bug Reports / Limited import of GCP
« on: June 22, 2017, 02:33:10 PM »
Something odly changed.
Working on a file with several chunks.
On the first chunk I imported a GCP coordinates file like always.
Almost 600 points have been imported without problem.
On the second chunk, I tried to import the same csv and le listing of point was limited to 11 lines.
Seens I never been able to import more than 11 points by file...

Things I tried that did not worked :
- import other markers list.
- close and reopen the file
- close and reopen the soft
- try with a new file
- reboot the PC
- update the soft

I have no more ideas...

This bug is really disturbing...

Does anybody add such problem ?

Thank you in advance if you can help me.


Ok, everything seems working.

But I thought that I could batch the export for several chunks running the script in the bacth tool.

Considering that the names of the projection markers will be the same (name, not coodinates), It could be possible to run automatically the script for each chunk with an exported file, named after the chunk name.

For now, the loading configuration window prevent the use of the script with the batch tool.

Anybody have some ideas to ease the process ?

Thank you in advance.
