ILS-04-001-13C

ILS-04 Laser-Based Vehicle Length, Width, and Height Detection System

ILS-04-001-13C

Single-bar I-type, 1 wide-high F13C + 1 long-high F13C

The Outer Contour System is a fully automated vehicle exterior dimension inspection system based on laser 3D scanning technology. By strategically deploying multiple high-precision LiDAR sensors (covering width-height, length-height, and lateral measurements), the system can construct a high-density 3D point cloud model of a vehicle in real time as it passes at high speed, accurately calculating its geometric parameters such as length, width, and height.
The system offers a variety of flexible installation topologies, including single-bar, dual-bar, and triple-bar configurations, enabling it to adapt to diverse and complex scenarios—from narrow lanes to extra-wide lanes, and from single-vehicle passage to continuous traffic flow. With a measurement accuracy of ±10 mm and a reliability rate of 99.9%, the exterior dimension system has been widely adopted in areas such as highway entrance weight enforcement, non-site law enforcement, vehicle exterior dimension inspection lines, and logistics volume measurement.

Overview

Centimeter-level accuracy, restoring the true contour.

Unlike coarse light curtains or visual estimations, the outer contour system employs high-frequency laser point cloud technology to scan vehicles from all angles. Whether it’s an ultra-wide cargo bed, exceptionally tall cargo, or even tiny rearview mirrors, the system can accurately capture every detail. ±1 cm Restore the accuracy to ensure the authority of law enforcement and testing.

Flexible networking, adaptable to any scenario.

Whether it’s a restricted toll island, an open weigh-in-motion plaza, or a standard inspection workshop, we provide services ranging from... Extremely simple rod To High-precision three-bar system 10 different configuration options. By freely combining the number and installation locations of LiDAR sensors, you can perfectly match your site conditions and precision requirements.

Continuous vehicle passage, efficient traffic flow

System support 0–40 km/h Wide-speed-range detection does not require vehicles to stop or maintain a constant speed. An advanced vehicle separation algorithm precisely segments closely following vehicles, enabling continuous free-flow detection and significantly improving lane throughput while preventing congestion.

The “Digital Ruler” for High-Speed Overweight Control and Vehicle Inspection

The outer contour system is “Entry-point Overweight Control” the core technology. It detects within milliseconds whether a vehicle’s length, width, and height exceed the limits before the vehicle even enters the toll booth, and simultaneously activates LED screens to advise the vehicle to turn back. Meanwhile, in... Vehicle Inspection Station and Logistics Distribution Center It replaces cumbersome manual tape-measure measurements, automatically generating volume data for vehicles or goods, thereby standardizing and digitizing the inspection process.

Systematic design, engineered implementation

10 configurations—choose according to your budget.

No two paths are exactly the same. The outer contour system offers an extremely wide range of configuration options:

Single-bar I-type: Just one L-shaped bar is all you need to achieve low-cost length, width, and height detection, making it ideal for continuous vehicle passage.
Double-bar type III: The gantry + L-arm combination offers higher precision and is suitable for off-site enforcement.
Three-bar I-type: Comprehensive, three-dimensional scanning, specially designed for inspection stations with extremely high precision requirements.

No matter your budget or venue size, we always have a solution to meet your needs.

Holographic scanning, revealing every detail.

The system integrates data from the “height radar” located at the top, the “width and height radar” on the sides, and the “blind-spot radar” positioned diagonally.

This multi-view orthogonal scanning not only calculates the maximum outer dimensions—length, width, and height—but also clearly reconstructs the cab shape of the vehicle, the stacking configuration of the cargo, and even the details of the tow bar. The resulting color point cloud not only provides highly accurate data but also serves as intuitive enforcement evidence, leaving no room for evasion of over-limit violations.

Intelligent separation, automatic noise reduction

Based on years of accumulated traffic data, the outer contour system is equipped with a powerful data processing control cabinet.

The built-in algorithm can automatically eliminate false detections caused by road reflections, interference from flying birds, and trailer towbars. Particularly in scenarios involving following vehicles, the system can achieve highly accurate automatic vehicle separation by analyzing point cloud features at the front and rear of the vehicles, ensuring that each vehicle is accurately assigned to its own lane without data overlap.

Automatic calibration, minimalist operations and maintenance

Traditional multi-sensor system calibration is complex. The outer contour system features an automatic self-check upon power-on and automatic parameter compensation functionality.

The system supports remote status monitoring and fault diagnosis, eliminating the need for maintenance personnel to frequently climb ladders for adjustments. The core sensors feature industrial-grade IP67 protection, enabling them to operate stably over the long term even under outdoor conditions exposed to wind and sunlight, thereby significantly reducing lifecycle maintenance costs.

Precise Dynamic Weighing and Overweight Vehicle Detection & Guidance for Return

With the deepening implementation of the “National Unified Network” operation and the policy of “mandatory inspection for trucks and prohibition of overloaded vehicles,” highway toll plazas at entry points are facing unprecedented traffic pressures. Traditional static weighing systems are inefficient and prone to severe congestion; meanwhile, outdated dynamic weighing systems often prove inadequate when confronted with new cheating tactics such as skipping weigh stations, speeding through weighbridges, or driving in S-shaped patterns. Moreover, these systems struggle to accurately capture vehicle dimensions—length, width, and height—leading to oversight and misjudgments of overloaded vehicles. This not only results in lost toll revenue but also poses serious safety risks to highways.

Pre-Interception of “Three Excesses” Vehicles at Highway Entrances

In response to the highway regulatory requirement of “mandatory inspection for trucks and prohibition of overloaded vehicles,” the F1X series LiDAR is primarily used for early detection and proactive guidance before toll station entrances, addressing the pain points of traditional overloading enforcement at entry points—namely, “only able to measure weight but struggling to measure dimensions” and “on-site interception easily causing congestion.”
