Hi I've experienced the badly "slanted" panoramas twice now.

With the theta Z1 I can check against the standard HDR images it creates at the same time, which are level it therefore looks like it is the Matterport cortex algorithm that is causing straight panos to appear crooked.

This may be far fetched but is the AI levelling panos based upon what it thinks visually is horizon rather than using camera gyro information? The reason I think this is because both projects were high but with angled/irregular ceiling shapes (one a church one a large high industrial building).

Just wondered if anyone else has experienced this?

Being honest also to create a nice dolls house I think the 360 cameras need a nice horizontal ceiling line.

Any thoughts?
