LiDAR Mutual Inteference
LiDAR Mutual Inteference
Project Overview
This InnovateUK (CCAV) funded project was carried out in partnership with the UK’s premier metrology institute – the National Physical Laboratory (NPL).
We conducted extensive testing across a range of environments – from controlled indoor and outdoor laboratories to real-world deployments where LiDAR sensors were mounted on a moving vehicle and road-side units. The tests examined numerous pairings of ‘victim’ and ‘offender’ LiDAR units, spanning different LiDAR technologies and scanning patterns, as well as mitigation strategies such as varying tilt angles and applying noise removal algorithms.
Key Outcomes
Our results show that several commercially available LiDAR units are vulnerable to mutual interference from other LiDAR devices, indicating that some manufacturers have not adequately mitigated this effect. We also assessed the practical implications of this phenomenon and identified several limiting factors that arise under realworld operating conditions.
