LiDAR & Spatial Intelligence Glossaries
Four reference glossaries defining the technical vocabulary of 3D LiDAR sensing, perimeter security, airport passenger flow, and physical AI. Published by Quanergy.
About These Glossaries
Specifying a 3D sensing system means working across four overlapping vocabularies: the physics of the sensor itself, the language of physical security, the operational metrics of passenger and crowd flow, and the emerging terminology of physical AI. These glossaries define each in turn, in plain language, for engineers, integrators, security professionals, and operations teams evaluating or deploying LiDAR-based systems.
3D LiDAR & Sensing
The sensor itself: point clouds, time-of-flight, beam steering, mechanical scanning, detection range, edge processing and object classification. Start here if you are comparing sensor architectures.
View glossary →Perimeter Security
Intrusion detection language: virtual tripwires, detection zones, sterile zones, false versus nuisance alarms, layered security and VMS integration. For security integrators and facility teams.
View glossary →Airport & Crowd Flow
Passenger flow and queue analytics: Level of Service, throughput, dwell time, queue wait time, density mapping and origin-destination matrices. For airport operations and aviation planners.
View glossary →Physical AI & Spatial Intelligence
How AI perceives and acts in the physical world: edge inference, digital twins, occupancy grids, sensor fusion, multi-object tracking and real-time event detection.
