The stereographic projection is a popular method for viewing spherical panoramas because of its ability to represent the scene as a “little planet” with a simulated overhead view. However, the stereographic projection does not work well for indoor scenes. In this paper, we present a method for producing a counterpart to the stereographic projection for indoor scenes. The main innovation of our method is the introduction of a novel azimuthal map projection that can smoothly blend between the stereographic projection and the Lambert azimuthal equal-area projection. Our projection has an adjustable parameter that allows one to control and compromise between distortions in shape and distortions in size within the projected panorama. This extra control parameter gives our projection the ability to produce superior results over the stereographic projection.
