FJD Trion S2 Series LiDAR Scanner

The FJD Trion S2 Series LiDAR Scanner is a professional mobile LiDAR scanning system designed for fast 3D data capture in surveying, construction, mining, forestry, infrastructure inspection, property management and incident documentation. It combines LiDAR scanning, integrated GNSS, a high-precision IMU, dual fisheye cameras, VIO and LiDAR SLAM into a compact field-ready solution.

For field teams, the main advantage is workflow efficiency. The S2 Series helps capture colourised, georeferenced point clouds while the operator moves through the site. Instead of relying only on static scanning positions or conventional measurement methods, users can collect large areas, complex spaces and difficult terrain with a flexible handheld or mounted setup.

Key Advantages

• Compact mobile LiDAR scanner for professional 3D reality capture.
• Available in S2, S2 PRO and S2 MAX configurations.
• Up to ≤ 1 cm relative accuracy in experimental conditions.
• Integrated GNSS, IMU, dual 12 MP cameras, VIO and LiDAR SLAM.
• Real-time colourised point cloud visualisation with FJD Trion Scan.
• Supports georeferenced point cloud workflows and over 8,000 coordinate systems.
• Flexible deployment with handheld, vehicle, drone, backpack, extension pole and other mounting options.
• Compatible with FJD Trion Scan, FJD Trion Model, FJD Trion Model for Pad, Model Web and FJD Trion Cloud workflows.

Built for Fast Field Capture

The FJD Trion S2 Series is designed to start quickly and move smoothly between field tasks. The integrated design brings the camera, IMU and GNSS module together in one system, helping teams reduce setup time and maintain productivity during fieldwork.

Depending on the model, the S2 Series offers either 16 or 32 LiDAR channels and point output of up to 320,000 or 640,000 points per second. This allows users to select the version that best fits the required scan detail, working distance and project type. For general large-site capture, the S2 offers balanced performance, while the S2 PRO and S2 MAX provide higher point output. The S2 MAX also extends the range to 300 m at 80% reflectivity.

Reliable Colourised Point Clouds

The scanner uses dual 12 MP fisheye cameras for real-time colourisation. In practical terms, this helps make point clouds easier to interpret because visual context is available directly in the scan data. This can be useful for building documentation, site inspections, asset records, forestry analysis, construction monitoring and digital twin workflows.

Advanced VIO and LiDAR SLAM help the scanner maintain stable performance while moving through complex spaces. This is especially valuable in environments where GNSS alone is limited, such as urban corridors, forests, tunnels, indoor-outdoor transition zones and construction sites with obstructions.

Georeferenced Mapping and GIS Integration

With integrated GNSS and support for more than 8,000 coordinate systems, the FJD Trion S2 Series fits into professional GIS, mapping and surveying workflows. Starting in the correct coordinate system helps reduce manual conversion work and can make the transition from field data to deliverables more efficient.

The system supports RTK accuracy specifications of 8 mm + 1 ppm RMS horizontally and 15 mm + 1 ppm RMS vertically. For surveying and mapping users, this supports workflows where point cloud data needs to be connected to project coordinates, control points or local geospatial reference systems.

Flexible Deployment Options

The FJD Trion S2 Series can be used in multiple field configurations. The brochure lists deployment and accessory options including car mount, drone mount, quick extension pole, robot dog mount, backpack, stabilising vest and rolling suitcase. This flexibility makes the system suitable for open construction sites, elevated areas, hard-to-access spaces, long corridors, forested areas and larger mapping projects.

For operators, the practical benefit is adaptability. A handheld setup can be used for fast walkthroughs, a vehicle setup can cover larger sites more efficiently, and a drone or elevated mounting option can help capture perspectives that are difficult to reach from the ground.

FJD Trion Software Ecosystem

The S2 Series is designed to work with the FJD Trion ecosystem from capture to processing and collaboration. FJD Trion Scan supports continuous site capture, real-time colourised point cloud viewing, coverage checks, scan sessions of up to 1 hour and resume-from-breakpoint functionality.

For processing and deliverables, FJD Trion Model and FJD Trion Model for Pad support field review and point cloud processing. FJD Trion Cloud and FJD Trion Model Web support sharing, review and collaboration, helping teams work with scan data without being limited to one device or local storage workflow.

Deliverables from One Scan

The S2 Series is suitable for more than just raw point cloud capture. The brochure describes workflows for point clouds, 2D floor plans, 3D mesh models, 3D Gaussian Splatting and georeferenced panoramas. This makes the scanner relevant for survey deliverables, CAD and BIM preparation, engineering documentation, facility records, property management and immersive visualisation.

HyperDense+ Enhanced Detail

When processed in FJD Trion Model, HyperDense+ can generate 5–7 times denser point clouds with up to 1 mm spacing. This can help improve fine surface detail and colourisation for users who need more detailed scan outputs for documentation, modelling or analysis.
