Abstract
Provided is a method of acquiring an optimized closed curved surface image using multiple cameras, and more particularly, an image providing method that produces a single image using a plurality of cameras fixed to a rig and having different capturing viewpoints, the method including projection operation of acquiring a single image by projecting images acquired from the plurality of cameras on a projection surface of a closed curved surface based on parameter information, rendering operation of fitting the acquired single image in a quadrangular frame for each region through a non-uniform sampling process, and viewing operation of mapping the sampled image to a viewing sphere.
