Metadata: Orientation comparaison

Hi everyone,

 

I'm currently working with my GoPro Hero 8 and I need to determine its orientation. In the metadata, I see two options:

 

- CORI: Quaternion representing the camera's orientation for each frame (60 Hz in my case)

- ACCL and GYRO fusion: Using Madgwick's filter, I'm able to estimate the orientation of the camera (200 Hz)

 

Which one is more precise? With a higher frequency, will my estimation will be better? Currently, I compared the data on Matlab, and I find the CORI's result less accurate.

 

Thanks

I don't know the answer, but you could raise the question in the telemetry group: https://community.gopro.com/t5/GoPro-Telemetry-GPS-overlays/gp-p/Hero5MetadataVisualisation
