Automated Vehicle-to-Road Height Detection & Surface Inspection

While road maintenance is gradually becoming smarter, traditional manual inspections remain hampered by low efficiency, frequent false alarms, and significant safety hazards. Minor road surface subsidence and hidden ruts are exceptionally difficult to detect visually. This lack of visibility not only threatens driving safety but also limits the scientific rigor and timeliness of road maintenance decisions. Overcoming this bottleneck is critical to advancing the automation and accuracy of road infrastructure monitoring.

Challenge: Inefficient Manual Road Profiling

Manual inspections are inherently slow and tiring for operators, frequently leading to missed or incorrect detections. When road cracks and potholes are not found or addressed in time, they degrade further under traffic loads. Modern infrastructure requires dynamic, automated solutions capable of continuous data collection at highway speeds.

Solution: SinceVision SGI400 Laser Displacement Sensor

In the realm of specialized automotive manufacturing, outfitting vehicles for infrastructure monitoring requires highly reliable hardware. To modernize automotive inspection routines for road maintenance, SinceVision Intelligence provides a high-precision automated solution.

By mounting two SinceVision SGI400 laser displacement sensors at the front of the inspection vehicle, engineering teams can fully automate the measurement process. Operating as an ultra-fast distance sensor, the SGI400 collects massive amounts of profile data while the vehicle drives normally, easily identifying localized subsidence and unevenness defects.

Core Technical Capabilities and Accuracy

The SinceVision SGI400 delivers real-time, precise elevation angle monitoring to support fully automated inspection processes.

• High-Frequency Sampling: Captures data at an ultra-fast 88 kHz, ensuring no minor deformations are missed even at high vehicle speeds.

• Millimeter-Level Precision: Achieves an accuracy of 0.1 mm within a broad measurement range of ±100 mm.

• Strict Repeatability: Features 2 μm repeatability and a high linearity of ±0.05% F.S. for highly stable data collection.

• Broad Protocol Support: Seamlessly integrates with standard industrial communication protocols to transmit real-time data and position information to the vehicle's central computer.

Rugged Reliability for Harsh Environments

Road inspection vehicles operate in unpredictable, harsh outdoor conditions. The SinceVision SGI series is specifically engineered to maintain optical stability outside of the laboratory.

• Ambient Light Resistance: Demonstrates strong resistance to shifting sunlight and external light interference during daytime operations.

• Vibration and Shock Resistance: Meets strict IEC standards, guaranteeing stable data acquisition despite continuous road vibrations.

• High-Speed Data Storage: Equipped with 1.2 million data storage capacity for rapid, high-speed read and write operations.

• IP67 Protection Rating: Fully sealed against heavy dust, humidity, and rain, ensuring uninterrupted performance in severe weather.

By integrating SinceVision laser displacement sensors, road maintenance fleets can eliminate the inefficiencies of manual checks, accurately capture exact rut depths, and make highly informed, data-driven infrastructure decisions.
