1. Bottlenecks & Challenges in Traditional Truck Payload Management
In high-frequency industrial transportation scenarios such as mining, aggregate quarries, cement plants, construction materials, and bulk cargo ports, trucks perform frequent material loading and hauling operations daily. Rapidly and accurately determining the actual payload volume and weight for every truck is key to driving cost reduction and operational efficiency.
Traditional payload monitoring relies heavily on manual visual estimation or standalone truck scale (weighbridge) weighing. However, real-world operations suffer from clear pain points:
· Low Traffic Efficiency: Vehicles must come to a complete stop for weighing or manual registration, causing frequent bottlenecks at site entrances.
· Data Blind Spots: Weighbridges only provide total weight and cannot evaluate payload distribution or material geometry (e.g., “hollow loads,” “bridging/voids,” or “underloading”). Manual estimation carries large margins of error and is highly vulnerable to human fraud.
· Low Digitalization: Lack of real-time 3D spatial data collection prevents seamless integration with enterprise WMS or ERP systems.
2. 3D LiDAR Scanning: A Technical Breakthrough in Dynamic Volume Measurement
The 3D LiDAR-based dynamic truck volume measurement system captures 3D spatial profiles of both the vehicle and the payload surface via high-frequency point cloud scanning. By utilizing differential algorithms between the “Empty Scan” and “Loaded Scan,” it calculates net payload volume in seconds without physical contact.
2.1 Standard Operating Workflow
- Dynamic Triggering: Trucks enter the LiDAR scanning zone at speeds of 5–15 km/h, automatically triggering the system.
- High-Density Point Cloud Acquisition: The LiDAR sensor rapidly captures high-precision 3D spatial coordinates of the truck bed and payload.
- Boundary Recognition & Differential Calculation: Algorithms automatically detect truck bed edges, filter out vehicle structural geometry, and compute net material volume.
- Cloud Integration & Automated Reporting: Volumetric data is transmitted real-time to a web platform, instantly generating 3D point cloud models and transaction logs.
2.2 Comparison: Traditional Weighing vs. ViLiDAR Dynamic Volume Measurement
| Feature / Dimension | Traditional Visual Estimation / Truck Scale | ViLiDAR Dynamic LiDAR Measurement System |
| Scanning Speed | 2–5 minutes per truck (Requires full stop) | 3–5 seconds per truck (Drive-through dynamic scan) |
| Fraud Prevention | Poor (Unable to detect density variance or void spaces) | High (3D point cloud visualization makes voids immediately clear) |
| Comprehensive Measurement | Captures total weight only; no spatial or volumetric data | Precise net volume calculation (Error 1-2%), with weight estimation based on material density |
| System Integration | Manual data entry; prone to human error and delays | Automated API generation; seamless integration with ERP / WMS platforms |
3. Expanding from “Volume Measurement” to “Smart Weight Management”
By processing 3D point clouds, the LiDAR system calculates exact payload volume V In practical field operations, the system allows configuring specific density parameters ρ for different material types (e.g., iron ore, coal, sand, gravel, wood chips) to dynamically estimate payload weight:
Estimated Weight = Net Payload Volume (V) × Configured Density (ρ)
Perfect Synergy Between Weighbridges and LiDAR: LiDAR is not meant to completely replace truck scales; instead, it works in tandem with weighbridges to form a “Volume + Weight” dual-verification mechanism. This not only prevents overloading, but also eliminates weighing discrepancies caused by moisture variations or unwanted debris.
4. Intelligent Management Software Platform: Data Visualization & Remote Supervision
ViLiDAR provides a web-based smart management software platform that allows site managers to remotely monitor logistics operations in real time without needing to be on site:
· Online 3D Point Cloud Preview: Real-time playback of 3D point cloud models for each truck to verify load distribution and surface levelness.
· Historical Audit Search: Multi-dimensional search filtering by license plate, arrival timestamp, and lane ID.
· Automated Report Export: One-click generation of daily, monthly, and quarterly haulage analytical reports to optimize site scheduling.
