What Is the FJD Trion P1?
The FJD Trion P1 is a lightweight handheld 3D laser scanner using SLAM (Simultaneous Localization and Mapping) technology. It captures accurate 3D point cloud data as you walk through a space, with LiDAR plus GNSS and 360° camera fusion.
| Aspect | Details | | --- | --- | | Technology | SLAM-based LiDAR + GNSS + 360° camera fusion | | Accuracy | ±2cm relative accuracy; ±5cm absolute accuracy | | Range | 40–70m max scan range | | Speed | 200,000 points/second; scan-to-post-processing ratio ~3:1 | | Best for | Indoor/outdoor scanning, GPS-denied areas, dark spaces, complex architecture |

Frequently Asked Questions
Q: What is the difference between SLAM scanning and tripod-based laser scanning?
SLAM scanning (like the FJD Trion P1) is handheld and ideal for fast walk-through scanning of complex or occupied spaces. Tripod-based scanning offers higher absolute accuracy (±2mm) but requires more setup time. SLAM is faster for large areas; tripod scanning is preferred for highest precision requirements.
Q: What accuracy can I expect from FJD Trion P1 scanning?
Relative accuracy: up to 2cm. Absolute accuracy: up to 5cm (with GNSS ground control). This is suitable for most architectural design, planning, and BIM workflows.
Q: What file formats do I receive?
Standard formats include .e57, .LAS, .LAZ, .PCD, .PTS, .PLY for point cloud data. BIM models are delivered in .RVT (Revit) and .IFC formats. 2D drawings in DWG and PDF.
