The hyperbolic mirror image above illustrates the problem with radially curved mirrors,
as opposed to conical mirrors, in that most of the useful image area is directed at the sky or at the ground/robot,
instead of being directed towards the areas of interest. Conical mirrors can be used to address this problem.
The resolution around the edge of a conical mirror is far better than the resolution near its apex.
The apex should be pointed up for close-up work and down for long distance views.
In each case the camera points at the apex.
