Simple drones provide usually yaw, pitch and roll values for preliminary orientation. But ArcGIS Pro is waiting for omega, phi and kappa (which is more common in professional photogrammetry).
ArcGIS Pro 1.4 currently does not support yaw, pitch, roll for camera orientation. However for drone images, these parameters are not required. if not available, as many drone images do, camera orientation will be computed automatically during adjustment process.
