Calculating 180 and 360 Camera Coverage

Hello John,
For typical high ceiling room 9 feet and AoV 360 with most comment camera resolution 1080 the width of scene = 6.28 x 9 = 56.5 and PPF =34. Also same result of Aov 180 when we increase the resolution and same data input just the PPF will increase

The question what is the dimension of each wall in the room (square, rectangular). For example, we have room with dimension of 12L x 12W x 9H it is covered.

We are looking at how to best incorporate camera height. This is especially important for 360 cameras where a camera mounted 30' high, is minimally 20 something feet away from people/cars, which will ensure poor quality video even if an object is directly underhead.

Filip, as for the Immervsion vs Fisheye differentiation, Immervision claims better quality at the edge. If there were any benefits, it would be a slightly different / wider effective FoV. We have tested Immervision and Fisheye lenses head to head (see here) and Immervision is better than some but worst than other fisheye, when testing regular, non edge areas. As such, it would not change the calculation / equation, only the potential area it was used over.

Sorry, but still having trouble. Here is a practical problem:

Assuming 360 mode and using your fisheye round picture of the parking lot, how would I go about determining the PPF of where the bushes are on the left?

Would I measure the distance to the bushes disgonally down or just the horizontal component of just the vertical? Thanks.
