T1 - Outdoor Gas Plume Reconstructions: A Field Study with Aerial Tomography T2 - 2024 IEEE International Symposium on Olfaction and Electronic Nose (ISOEN) Proceedings N2 - This paper outlines significant advancements in our previously developed aerial gas tomography system, now optimized to reconstruct 2D tomographic slices of gas plumes with enhanced precision in outdoor environments. The core of our system is an aerial robot equipped with a custom-built 3-axis aerial gimbal, a Tunable Diode Laser Absorption Spectroscopy (TDLAS) sensor for CH4 measurements, a laser rangefinder, and a wide-angle camera, combined with a state-of-the-art gas tomography algorithm. In real-world experiments, we sent the aerial robot along gate-shaped flight patterns over a semi-controlled environment with a static-like gas plume, providing a welldefined ground truth for system evaluation. The reconstructed cross-sectional 2D images closely matched the known ground truth concentration, confirming the system’s high accuracy and reliability. The demonstrated system’s capabilities open doors for potential applications in environmental monitoring and industrial safety, though further testing is planned to ascertain the system’s operational boundaries fully.

T1 - Bringing robot gas tomography to the next dimension - Aerial-based gas source localisation and gas distribution mapping using an open-path gas detector N2 - An unmanned micro aircraft (UAV) is equipped with an open-path gas detector to localise gas sources and to generate gas distribution maps. The gas detector is based on the tunable diode laser absorption spectroscopy (TDLAS) and attached to a 3-axis aerial stabilisation gimbal. Sensor validation experiments and first gas tomography reconstructions are shown.

T1 - Gas Source Localisation from the Next Dimension N2 - Leaking methane (CH4) from infrastructures, like pipelines, industrial complexes and landfills, or accidental hazardous goods transports is critical for the environment, but can also pose a risk to human life. To enable a fast detection and localisation of these kind of leaks, we developed a novel robotic platform for aerial remote gas sensing. The platform combines an unmanned micro aircraft (UAV), a 3-axis aerial stabilisation gimbal and an open-path gas detector based on the tunable diode laser absorption spectroscopy (TDLAS).
