Hi BradleyDillon ,
As a background, IMX378-W CCMs (PY060) have the following FOVs:
Since these are a bit distorted, after rectification (+undistrotion), the horizontal FOV will likely drop in a ballpark of 85°. So you would actually need 4-5 of these pairs to be able to cover full 360° view.
Mounting the two cameras (of the stereo camera pair) at an angle is currently not supported.
For an OAK-FFC 360 view I would actually suggest using OV9282/OV9782-W CCMs (PY059) which have wider FOV, after rectification of about 97°, so you would only need 4 and still have some overlap.
