What is correct value for pitch and roll

[itforester]

Hi
I am new to exif data and exiftools, but has worked with underwater AUVs.
I have received data from a user with a Flir Duo Pro R camera. The jpg files seem to have a pitch value of 84 and a roll value of 170. I would assume that the correct values should be around +5 to -5 when taking pictures of the grond. A roll of 170 degrees would mean that the plane was flying upside down. My assumption is that the correct value is Pitch/100.0.

Example:
GPSLatitude,           GPSLongitude,      GPSAltitude, Yaw,     Pitch,   Roll
70.2609252933333,30.7670879363889,49.572,     -20.67,  -81.99, 129.57
70.2608947751111,30.767332077,       49.757,     -28.41,  -81.41, 138.68

Can anyone please tell me if this is correct assumption?

PS: exiftools seems to be very good!

I have no idea.  First, it would be useful to know where the Yaw/Pitch/Roll information is stored (ie. the -G1 location).

But my guess would be that ExifTool is correct.  Was the camera pointed down?  If so, you would expect a pitch of about -90 (if these are the camera direction angles).

Your table shows a pitch of -81, which is close.  However in your description you mention a pitch of 84, which is nearly the exact opposite direction.

Edit:  It would be great if you could send me a sample from this camera (philharvey66 at gmail.com).  I don't have a JPG from this model yet.
