Ricoh Theta north metadata is really average ?


I trying to work with the theta internal compass direction witch can be found in the meta data (PoseHeadingDegrees or GPSImgDirection)

i made a few test, and it appears this data is very average, even on the latest Theta Z1

for example, if you setup theta on tripod, and take a set of pictures while turning the theta several time on its axis, and compare the north value, it can vary up to 25% !! and i even got very wrong data sometime

did someone noticed this? found an alternative?

Thanks !
