Sick launches LiDAR vehicle profile measurement system that can accurately measure the 3D profiles of multiple vehicles in motion

According to foreign media reports, Sick, a leading German sensor technology developer, has launched a lidar-based free flow profiler vehicle measurement system that can perform highly accurate measurements of the 3D profiles of vehicles in flowing traffic and multiple lanes.

Sick's versatile and adaptable vehicle profiling system can be used for vehicle tolling and vehicle classification applications, especially for vehicles with optimal load requirements such as ferries or trains, and for applications such as verifying vehicle dimensions to maximize revenue recovery. As vehicles travel freely on multiple lanes, Sick's 2D lidar sensors can perform high-frequency scans of traffic and automatically measure the length, width and height of vehicles. Typically, three Sick sensors are mounted on a traffic gantry, but the system can also be expanded to cover multiple lanes to accommodate different sensor layouts and obtain the required information for monitoring purposes. The system has a detection range of up to 130 feet (40 meters) and can measure the profiles of all vehicle types, including heavy highway vehicles, passenger cars, trailers and motorcycles.

Vehicle profile measurements are performed by the Sick Traffic Controller unit, resulting in a highly accurate 3D model of each car. The system captures the vehicle's size, type, direction of travel and assigned lane. In addition, functions such as vehicle classification, axle counting or detection of overheated vehicle components can be optionally integrated to meet specific local operating conditions and needs. The mobile profile measurement system can be installed in new equipment or can be retrofitted. It is easy to install and can accurately measure vehicle profiles at speeds of 0 to 75 mph (0 to 120 km/h). It can also be integrated with other traffic management monitoring systems such as optical character recognition (OCR) or automatic vehicle recognition (ALPR), CCTV (closed-circuit television) and security systems.

The system can be installed on traffic gantry or directly on the infrastructure of existing traffic lanes without damaging or interfering with the road surface. The IP67 protected Sick LMS511 Class 1 (visually harmless) lidar sensor has an operating temperature range of -30°C to 60°C. Moreover, the mobile vehicle profile measurement system allows operators to easily access the collected and processed data. It is easy to install and operate. Data can be accessed through a web browser. Data can be downloaded to the customer's traffic management control system through a TCP/IP interface, and the system automatically displays information on the last 50 vehicles.
