Equirectangular Image Quality Assessment Tool Integrated into the Unity Editor

Abstract

Equirectangular images are captures in 360° of user surroundings. Virtual reality applications provide immersive experience when using this type of media. However, in order to develop a 360 viewer it is necessary to choose among different media formats, resolution configurations and texture-to-objects mappings. This work proposes to develop a tool integrated into Unity editor to automatize the quality assessment of different settings of 360 image visualization. Using objective metrics, we compare the UV mapping of a procedural sphere, a Skybox rendering and a Cubemap.
