Geely Automotive Plant丨GS-120G SLAM Scanning Solutions for Factory Digital Twin

Factory Digital Twin Project | Geely Automotive Plant
High-Precision Handheld LiDAR Scanning with Geosun GS-120G

In a recent digital infrastructure mapping project at the Geely Automobile Manufacturing Plant, the Geosun GS-120G handheld LiDAR scanner was deployed to capture the complete layout of the factory’s interior and exterior in 3D with outstanding clarity and efficiency.

Spanning a vast industrial site with large workshops, complex machinery, long corridors, shaded logistics zones, and limited GNSS signal coverage, this project demanded a highly adaptable and accurate mapping solution. The GS-120G rose to the challenge — and exceeded expectations.

Thanks to its lightweight, ergonomic design, the GS-120G allowed operators to move swiftly and comfortably through both indoor and outdoor areas. Unlike traditional scanning methods, this compact handheld device required no tripods or bulky setups, significantly reducing field time and labor. Operators could walk through the facility and collect rich point cloud data in real-time, even in tight spaces and high-ceiling environments.

Project Highlights:

• Hesai XT32 sensor delivers dense, high-resolution point clouds with crisp structural detail

• Advanced SLAM algorithm enables seamless GNSS-free mapping, perfect for factory interiors, underground levels, and shielded corridors

• Portability and Ease of Use: The ultra-light handheld form factor made it easy to navigate narrow walkways and crowded plant zones, allowing a single operator to complete the full scan in just a few hours

• Time-Efficient Workflow: No need for repeated setup or stationing — just walk and scan

• Comprehensive Coverage: From exterior buildings and vehicle lanes to indoor equipment and overhead piping, all data was captured continuously

• Accurate Digital Twin Output: The result was a highly detailed 3D model, supporting asset management, maintenance planning, and smart factory upgrades
