Abstract
As a virtual tour and virtual reality technology advances, resolution with gigapixel panoramic images becomes available. Gigapixel equirectangular panoramic image needs to load and access without any delay through the internet by any device like mobile, tablet, or a computer. Also, several popular visualization formats like equirectangular projection were developed to map a real scene to a panoramic image. However, the most popular panoramic visualization technique equirectangular projection may not the best choice. Visualizing equirectangular images as spherical panorama has distorted nadir and zenith that can be affecting the viewing experience. So, we must consider image quality. In this research, we show the result of the evaluation for the projection formats using various comparison method to find which projection format (equirectangular projection, cubemap projection, and octahedron projection) and visualization technologies provide better image quality and speed of loading over Internet. We exclude other format that has lower quality than the equirectangular projection format used in this experiment.
