Over-height Detection
LiDAR is the sensor technology for over-height detection and collision avoidance as it provides 4D actionable insights to accurately detect objects. LiDAR increases safety by reducing accidents from over-height vehicles, which dramatically decreases costs by improving traffic flow.
Unlike traditional over-height systems, Opsys’ LIDAR, ALTOS, creates a real-time 4D image of a vehicle and the road and uses this information to provide the over-height warning. In its most simple version, using an optional ethernet relay with analog outputs, the system can be used to trigger a warning signal directly. We can communicate in protocols like D/IO or NTCIP. The ATLOS can also be integrated into more complex system traffic management systems using protocols like NTCIP.
Features & Benefits
-
Accurate over-height detection: delivers precise vehicle height measurements in real time, minimizing false positives and missed detections
-
High reliability in harsh conditions: solid-state design with no moving parts ensures consistent, long-term operation in roadside environments
-
Easy to deploy and maintain: all-in-one, compact unit with Power over Ethernet (PoE) simplifies installation on bridges, tunnels, or road gantries
-
Scalable across locations: ideal for multi-site deployments - units can be easily added to cover more roads, routes, or infrastructure assets
-
Supports smart infrastructure: integrates with existing signage or alert systems to automatically warn over height vehicles before damage occurs
-
Edge processing capabilities: processes data onboard for instant alerts, reducing latency and network dependency.

ALTOS 150 for Over-height Detection
This point cloud video shows Opsys’ demo software monitoring traffic on a highway. The ALTOS measures real-time vehicle dimensions to detect if a vehicle is too high to pass under a bridge or go through a tunnel. At the same time Opsys’ LiDAR sensor can monitor traffic speed and flow.
In this recording the ALTOS 150 unit is used with its maximum range of 150m and a FoV of 45° x 13°. The fully integrated solution is a perfect fit for different traffic monitoring application thanks to its simple installation and low cost due to the integrated perception stack.
