General / Re: Workstation setup for 210mpx oblique camera

210MP you probably mean using 5 different sensor/lenses/cameras? Not a single 210MP frame?

20.000 you can run easily on regular medium powerful workstation.

Hello bassistas,

Can you provide more detailed description of the steps followed starting from model generation (also specify the coordinate system of the chunk, model and CS options in export/import dialog)? I was not able to reproduce any problem with export-import workflow for FBX model in the latest pre-release version.

The issue still exists in the latest stable release 2.1.0. The project contains photos from a DJI drone and laser scans imported as e57 files. The coordinate system is WGS 84, it doesn't matter which options I choose during the export or what file format, the exported model always comes up shifted by a few meters from the original position. I can send you an example project  (without the photos and laser scans) to investigate if you want.

Sounds like your problem is because you are using WGS84 as coordinate space, why not use a real coordinate space with accuracy and measurements, not something in degrees.

This is from Agisoft support.

Based on the available information from DJI, calibration using dewarp does not use the k4 parameter and when calibrating, it uses a camera type like fisheye.

Please try to set the camera type - Fisheye and fix k4 = 0. Then compare the calibration results. We think this can improve the calibration result.

Can you post a screenshot of the Difference tab at 25X

Here is same photo, different project, showing problem and then no problem, both K4.

Same drone different dataset, Same processing method and K4 used as well, looks ok here.

This is how it looks for me with K4, seems to work fine.

Are you making sure you project your images FIRST into the correct GEOid.

Dear Alexey,
I am using Version 2.0.1 (64 Bit) on a Mac M1.
thank you

Can you please update to the newer build.

So like a normal map?

Have you projected the drone images into the correct GEOid?

What would be the benefits of using this instead of the already meta-tagged images. As in This data VS the Metadata in the pictures.

13

Yes again, you need to project the images of the drone into the correct GEOid. Before you do anything else. You need to get the drone images into the correct Z height and the geometry of the GEOid.

14

Start with projecting the drone images into the correct GEOid. This should fix your issue.

You need to project the drone images into the GEOid you are using.
