Visual Final Landing System (VFLS)

It is an Intelligent Spreader Guidance System based on multimodal sensor fusion. By leveraging advanced computer vision technology and reusing only the CCTV camera mounted on the Spreader, and through a dedicated visual foundation model, it achieves full-process automation from container placement at the first tier to high-tier stacking.

Core capacity:
HIRI VFLS is a lightweight vision model for ports, enabling joint perception of semantic and spatial awareness.
Minimal hardware + algorithmic compensation, requiring only the reuse of the original CCTV camera on the Spreader.
Supports primary/secondary guidance for dual 20-foot containers during container loading.

Product Features:
Minimalist Hardware
Only the original 4 CCTV cameras on the Spreader need to be reused, without the need for additional LiDAR or multi-camera arrays, significantly reducing hardware costs and system complexity.
High-precision positioning
By integrating semantic perception and spatial perception technologies, the system achieves centimeter-level positioning accuracy for Spreader at high altitudes and millimeter-level positioning accuracy near containers, meeting the requirements for full-process automation of container stowage.

Strong scene adaptability
A dedicated visual model trained on a large amount of real port data maintains stable recognition and positioning capacity in complex scenarios such as strong light, shadow, container rust, and stacking interference.
Easy maintenance
By adopting front-end fusion technology and a unified coordinate system, the system avoids the problem of multi-sensor calibration drift, resulting in high Stability and low maintenance costs.
Full-process support
It covers the entire Operation Procedure from container loading at the first tier, high-tier stacking to precise container grasping, supports primary/secondary guidance for two 20-foot containers at a time, and adapts to diverse operational needs.
