FJD Trion LiDAR Scanner — Products

Overview

Modular by Design

The FJD Trion combines a 16 or 32-channel LiDAR sensor with dual 12MP fisheye cameras and a high-precision IMU into a compact, field-hardened unit. An optional RTK module adds GNSS-based absolute georeferencing when needed.

Whether you're walking a construction site, flying a drone over open terrain, or inspecting an underground tunnel on a robot, the same scanner, the same software, and the same data pipeline.

Key Technologies

What Sets It Apart

01 — Hardware

Multi-Module Integration

The Trion's modular architecture lets you configure the scanner for each project. Attach the RTK module for outdoor geo-referencing, remove it for GPS-denied indoor environments to save weight.

16/32 LiDAR Channels — choose point density to suit your accuracy needs and battery constraints
2 × 12MP Fisheye — full 360° colour capture for true-colour point clouds
RTK Module — optional snap-on for survey-grade absolute positioning

02 — Algorithms

Multi-SLAM Algorithms

Two SLAM algorithms run in parallel: LiDAR SLAM for feature-rich environments and Visual-Inertial Odometry for featureless or GNSS-denied spaces. The system automatically fuses both to maintain trajectory accuracy through every condition.

LiDAR SLAM — geometry-based loop closure in structured outdoor and indoor scenes
Visual-Inertial Odometry — camera + IMU fusion for dark, low-structure, or underground areas
Automatic fusion — no manual mode switching required in the field

03 — Georeferencing

PPK Support

Post-Processing Kinematic correction enables survey-grade absolute accuracy without requiring a live RTK correction stream during capture. Return to the office, apply base-station data, and achieve centimetre-level georeferencing.

No live connection needed — scan freely, correct in post
Centimetre absolute accuracy — suitable for survey and mapping deliverables
Works with any CORS network — use existing base station infrastructure

All-in-One Workflow

Collect. Process. Deliver.

The FJD ecosystem covers every stage — from field capture through to client-ready deliverables, all within one software platform.

1 — Data Collection

Walk, fly, or drive. The Trion captures dense colourised point clouds in real time with on-device SLAM processing. Preview your scan before leaving the site.

2 — Data Processing

Import to the companion software for registration, noise filtering, classification, and georeferencing. Apply PPK corrections and export in any standard format.

3 — Collaborate & Deliver

Share point clouds, create measurements, mark annotations, and deliver to clients via secure cloud links — no specialist viewer software required.
