Increase number of points in cloud from photogrammetry
« on: April 24, 2025, 05:31:51 PM »
Hello,

I'm working on creating point clouds of fruit trees from images collected in RGB by the DJI P1. I supplied the same images to Metashape and DJI terra. I found that DJI Terra produced a much better cloud than Metashape. It contains many more dots and the trees seem to conform to the photos. I'm a bit disappointed because I thought Metashape was a more powerful program than DJI Terra.

Can you tell me what parameters to use with Metashape to increase the number of points in the cloud? I did the alignment in ultra high quality, I tried moderate depth filtering and desactivate depth filtering, I modified the cloud quality level without success. Metashape has other advantages that make me want to continue using it.

Thank you

Fabien

Hello Fabien,

Is it possible to share Metashape project with alignment results and the related original images to support@agisoft.com, so that we could try to reprocess the data on our side?
Additionally please share the point cloud obtained from the same set of images in DJI Terra for comparison.
Best regards,
Alexey Pasumansky,

Dear Alexey,

I can see that you downloaded my data on 28/04/2025 but I haven't heard back from you. Can you inform me of the progress of my question? Have you managed to produce a cloud at least comparable to the one produced by DJI terra?

Best regards

Fabien

Dear Alexey,

I still don't have an answer. It's a disappointment because I thought that Metashape was very accomplished. It's very configurable and takes a long time to learn. On the other hand, DJI Terra is very simple, just a few clicks away. If Metashape's sophistication doesn't add value on this point, that's a bit sad.

Can you share the dataset?

Metashape is much better then Terra as you have almost Zero controls in Terra.
