报告简介：

3D Point clouds (PCs) are now available for diversified applications in our work and life, with creation of digital twins for almost everything in the physical world, enabled by rapid development of depth sensing, photogrammetry and deep learning; they offer unprecedented possibilities in digital transformation and smart cities, ranging from a single object (like a desk or statue) to an entire city, toward BIM/VR/AR/metaverse, smart manufacturing, urban surveillance/planning, cultural heritage preservation, crime investigation, robot navigation, autonomous driving, and medical/biological sciences.

This talk will present the recent research and development for PC representation, evaluation and utilities. Related important topics include various filtering and processing, simplification, compression, shape/mesh construction, and image-based localization. More exciting possibilities are expected because PCs provide a bridge between computer vison and computer graphics which had been two largely separated domains for long and facilitate comprehensive multimedia interaction; Possible future research directions will be therefore highlighted and discussed as well.
