New Cifre PhD thesis in collaboration with Samp AI

Samp AI is a startup company specialized in digital twins of industrial sites.

The Cifre thesis will start in December 2022 on the topic "Random Accessible Compression of Structured 3D Point Clouds for Interactive Visualization" and will be supervised by Pierre Alliez (Inria), 3IA Côte d'Azur chairholder.

Laser scans of industrial facilities contain massive amounts of 3D points which are very reliable visual representations of these facilities. These points represent the positions, color attributes and other metadata about object surfaces. Samp turns these 3D points into intelligent digital twins that can be searched and interactively visualized on heterogeneous clients, via streamed services on the cloud. The 3D point clouds are first structured and enriched with additional attributes such as semantic labels or hierarchical group identifiers. Efficient streaming motivates progressive compression of these 3D point clouds, while local search or visualization queries call for random accessible capabilities.
