Bug Reports / Blocks Exchange import/export does not work with Fisheye

« on: March 08, 2023, 09:04:17 PM »

Hello.

When exporting the data into Blocks Exchange format, any information about the Fisheye camera intrinsic and distortion coefficients is lost.

Yes. I understand that Metashape and Context Capture use completely different distortion models for fisheye cameras.
What I don't understand is why even the basic information is lost (like focal length and camera extrinsics).

Is it supposed to work that way? Or is it an actual bug?

Metashape version is 2.0.0.

Hello again.

Is it still possible to get an answer?

General / Specifics of the markers-based alignment

« on: February 25, 2023, 04:43:18 PM »

Hello, everyone.

I cannot see in the documentation any information for the markers-based chunk alignment regarding the markers reliability.
Does "Align Chunks" feature use RANSAC filtering or sequential RANSAC filtering for the markers pairs?

Thank you in advance,
Andrey.

Thank you. I will try that.

General / Is it possible to feed custom keypoints and matches to the triangulation?

« on: November 14, 2022, 03:32:20 PM »

Hello, everyone.

I am using Metashape for the camera alignment task (especially because Metashape uses  Brown's distortion model).
The problem is that I am dealing with a series of photos of long brick walls with similarly looking windows.
Long story short, the default key points/matches are not enough to perform the triangulation correctly (no GPS available).

I learned, how to process the key points and matches outside the Metashape. However, I did not find a way, to import new key points and matches back into Metashape.

Does some one know, how can one achieve that?

Thank you in advance.
