Python and Java API / Re: Report generation does not show GCPs in the report even when they are present

Hi Alexey,


It appears to have been a bug in the script that we used. 
Fixing that bug solved our problem 

Thanks for the prompt reply!

Python and Java API / Report generation does not show GCPs in the report even when they are present

« on: April 25, 2024, 09:35:04 AM »

Recently ran a dataset for processing.

The steps i followed was:
- Add photos
- Add geotags
- Run workflow -> Align Photos
- Add GCPs
- Filter photos by markers, Tag GCPs
- Optimize Cameras
- Run workflow -> Generate Report

Please be noted that this was done using Metashapes Python API.
The expectation was that I would be able to see the Ground Control Points in the report generated. However that was not the case. What could be the potential causes for this? Could it be an issue of the dataset i used? Any step that I am missing?

Thanks in advance.

General / Re: Tie points checkbox disabled in Merge chunk workflow

« on: January 09, 2024, 11:08:36 AM »

Hi Alexey,


Continuing on what was said in the previous post, we found out the reason that metashape was not showing the option of merging tie points. It was because, in our settings we had not enabled the `Keep Key Points` options checked.

What I want to know is for what reasons would one actually select the option to merge tie points?
Is there any benefit to using that while merging?

From my understanding merging chunks automatically adds the two tie points together, and on generating a dense cloud -> dem -> ortho from this, (for 2 chunks with 100 images each), there doesn't seem to be any visual difference. However, there is a difference in number of points which i assume is due to the removal of any duplicate tie points?


Thanks!
