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 — ideal for fast reality capture in surveying, construction, and 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 .las, .pcd, .pts, .ply for point cloud data. BIM models are delivered in .RVT (Revit) and .IFC formats. 2D drawings in DWG and PDF.
