Panoramic Cameras Wall vs Ceiling Mount

Author: Ethan Ace, Published on Jul 12, 2016

Panoramic cameras are almost always ceiling mounted, looking down for a general overview of the scene, but is this really the best location, or can wall mounting provide similar or better details and overview?

To find out, we shot out panoramic cameras in two scenes, indoors and out:

Inside, we see how mounting style impacts performance and answer the following questions:

  • Which mounting style provides better facial details?
  • How does overview performance differ?
  • Does either mounting type waste significant FOV area?
  • How do software and hardware dewarping impact these issues?
