Hydra: A Real-time Spatial Perception System for 3D Scene Graph Construction and Optimization [PDF]
Robotics: Science and Systems Conference, 2022 3D scene graphs have recently emerged as a powerful high-level representation of 3D environments. A 3D scene graph describes the environment as a layered graph where nodes represent spatial concepts at multiple levels of abstraction and edges represent ...

Improved Conflict Detection for Graph Transformation with Attributes [PDF]
Electronic Proceedings in Theoretical Computer Science, 2015 In graph transformation, a conflict describes a situation where two alternative transformations cannot be arbitrarily serialized. When enriching graphs with attributes, existing conflict detection techniques typically report a conflict whenever at least ...

You Only Look Once: Unified, Real-Time Object Detection [PDF]
Computer Vision and Pattern Recognition, 2015 We present YOLO, a new approach to object detection. Prior work on object detection repurposes classifiers to perform detection. Instead, we frame object detection as a regression problem to spatially separated bounding boxes and associated class ...

TIMESTAMP OFFSET DETERMINATION BETWEEN AN ACTUATED LASER SCANNER AND ITS CORRESPONDING MOTOR [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017 Motor actuated 2D laser scanners are key sensors for many robotics applications that need wide ranging but low cost 3D data. There exist many approaches on how to build a 3D laser scanner using this technique, but they often lack proper synchronization ...

A Generic Plug & Produce System Composed of Semantic OPC UA Skills
IEEE Open Journal of the Industrial Electronics Society, 2021 Typical industrial workcells are composed of a plenitude of devices from various manufacturers, which rely on their own specific control interfaces. To reduce setup and reconfiguration times, a hardware-agnostic Plug & Produce system is required.

Point Cloud Registration With Object-Centric Alignment
IEEE Access, 2022 Point cloud registration is a core task in 3D perception, which aims to align two point clouds. Moreover, the registration of point clouds with low overlap represents a harder challenge, where previous methods tend to fail.
