Method to Camera Placement

[JoelOA]

Hi,

I am working on replicating this with the CoDrone Pro and the Arducam B0332. The Arducam I am using has a 70 degree FOV, will I be able to replicate the project with 4 camera's or I will need more than 4 because my camera's FOV is less than 90. Generally, is there a method for figuring out how to place the camera's to capture the entire space (room) the drone will be flying in ?
