Semantizing Complex 3D Scenes using Constrained Attribute 04-09-2017 12:00
Hello guys,

We propose a new approach to automatically semantic complex objects in a 3D scene. For this, we define an expressive formalism combining the power of both grammars and constraint attributes. It offers a practical conceptual interface, which is crucial to write large maintainable specifications. As recursion is inadequate to express large collections of items, we introduce maximal operators, that is to reduce the parsing search space. Given a grammar in this formalism and a 3D scene, we show how to automatically compute a shared forest of all interpretations - in practice, only a few, thanks to the relevant constraints. We evaluate this technique for building semantization model using CAD model examples as well as photogrammetric and simulated LiDAR data.


I did not find the right solution from the internet.
