Hello,
I’m validating a virtual UAV flight path for photogrammetric quality so I can make sure I’ll get good coverage prior to testing in the real world.
I’m using Airsim and Unreal Engine and am exporting a series of 1080p images with a python script. I have no exif data / metadata etc etc, it’s just clean pngs.
When I import my images I first note that they are showing the incorrect resolution, 256x144 instead of 1920x1080.
When I click “Align Images”, I get the message “Aligning Images, finished in 0 seconds”, and “Render mode has been switched to vertices…” but none of the images register.
For ref, I have a full license purchased through Steam and a pretty beefy desktop. I’ve also tried importing into Agisoft and they come through with the correct resolution and can align.
Thanks for the help!
Did you check the setting “Merge components only”? It needs to be set to false…
That won’t help with the resolution issue though…
I’m validating a virtual UAV flight path for photogrammetry using Airsim and Unreal Engine, but my exported 1080p images are showing an incorrect resolution of 256x144 upon import and fail to align. Interestingly, these images align correctly in Agisoft. To resolve this, ensure your images display the correct resolution before alignment or consider using Agisoft if issues persist. Additionally, integrating high-quality Ground Control Points (GCPs) is crucial for enhancing geo-referencing accuracy. I recommend using weatherproof GCPs like Propeller AeroPoints or creating your own with printable templates. Properly placing and measuring GCPs across your site will significantly improve your data accuracy.
