A "smart controller" for the gen #1 Mavic Pro? No such animal. That type of integrated controller only started with the Mavic 2 series (RM500) which is not compatible with the original Mavic Pro.
Might Microsoft's ICE-Image Composite Editor help with this? It isn't supported anymore, doesn't really need to be, but is available for download.
It will remove the perspective distortion to make orthogonal frames and stitch them together...
