Description

"computed_rotation": [ 1.5361960317811, -0.57250186595465, 0.54694338796389 ]

I saw in openstreetmap when we load the streetview images, theres is a field in response 'computed_rotation' which is coming from the OpenSFM. It seems it's reading the quaternion values present in camera Orientation and converting it into rotation vector, but it's not coming up correctly. Can someone explain how it's being calculated?

Research direction

The issue concerns the computed_rotation response field and camera Orientation values in OpenSfM; no source file or test is identified. Trace where computed_rotation is produced, compare the quaternion-to-rotation-vector conversion with the street-view input, and establish the expected result before documenting or testing the behavior.
