Not all 3D scanning projects require the same level of accuracy, range, or complexity. This guide helps you quickly identify which FJD Trion scanner best fits your workflow, environment, and budget.
Step 1: What Type of Environment Do You Scan?
Indoor, Mixed Indoor & Outdoor, Mobile Workflows
- Smartphone-based, ultra-portable
- Works indoors without GNSS and outdoors with RTK
- Ideal for fast deployment and flexible scanning
Best for:
Facility mapping, indoor BIM, utilities, property documentation
Outdoor, Complex or Urban Environments
👉 P2
- Strong Multi-SLAM fusion
- Longer scanning range
- Designed for high-quality georeferenced point clouds and 3DGS
Best for:
Urban mapping, infrastructure, land surveying, digital twins
Entry-Level, Budget-Friendly, Easy Reality Capture
👉 P1
- Simple, plug-and-play LiDAR scanning
- No complex calibration
- Excellent balance between performance and affordability
Best for:
AEC, property management, public safety, media & visualization
Large-Scale, Long-Range, Harsh Environments
👉 S1
- Longest scanning range
- Highest point cloud density
- Works underground without GNSS
Best for:
Mining, tunnels, forestry, large industrial sites
