Abstract

This paper presents the MUSAL ecosystem, which allows temporal scene modeling with multi-sourced data and provides a continuous scene representation at different abstraction layers. It consists of individual building blocks, each of which implements different functionalities and is orchestrated by a ROS2-based middleware. The building blocks are comprised of (i) data stores, which implement the actual persistence and management of the sensor data; (ii) data recorders, connecting the actual sensors with the data stores; (iii) data processors, that advertise services to process the sensor data on different abstraction levels; as well as a (iv) universal search engine, providing a unified and transparent interface to the user. The functionality of the system is demonstrated through four use cases, namely the generation of obstacle maps and their distribution between multiple autonomous mobile robots, collaborative online 3D mapping and point cloud merging, multi-source image-based 3D reconstruction, and the monitoring of industrial facilities.
