Physically-based Lighting of 3D Point Clouds for Quality Assessment

Résumé

Point clouds are acknowledged as an essential data structure to represent 3D objects in many use cases, notably immersive experience settings such as Virtual, Augmented or Mixed Reality. This work is the first part of a research project on immersive Quality Assessment of point clouds in different lighting. In this report, I focus mainly on the physically-based rendering of such data in Unity 3D, and the impact of point cloud compression when considering various lighting conditions on the objects. These first observations and results will serve in the implementation of a 6DoF immersive experiment setting for subjective quality assessment.
