The orientation propcase gives it in 90 degree increments. I'm not aware of any source that gives it with higher precision.

Cameras like the SX50 have an OSD function that shows how level the camera is.  So the info for those models is in there somewhere.

Also, IIRC there is a very old post here on the forum (2008?) that has a video of a similar function implemented in CHDK.  Of course I can never find it when I want it.....

Probably https://chdk.setepontos.com/index.php?topic=1365.0

G7X has the electronic level function, but I haven't investigated how to get the information.

Some time ago we have made some experiments with a Lua script. GetISLensEViAaxis and GetISLensEViBaxis could be helpful functions. A great problem was, depending on camera they return different values.

The script ran on the sx220 and sx260 very well.

Go into the CHK menu: Miscellaneous Stuff => Enable Lua Native Calls

Seems to crash my G10.  The camera just restarts - no ROMLOG is created.

If I get a moment I'll fiddle with it.  Might be that the camera is too old and does not support the necessary event procs.

Edit : resets camera when it calls :
Code: [Select]
    A = call_event_proc("GetISLensEViAaxis")
    B = call_event_proc("GetISLensEViBaxis")

Some questions:
1) I need to edit angle correction every 1-2 minutes. Why is it occur?
2) Is there any way to get pitch angle also?
