FJDynamics FJD Trion S1 Handheld SLAM 3D Laser Scanner

FJD Trion S1 – Portable SLAM 3D Scanning for Real-World Mapping

The FJD Trion S1 is a handheld 3D LiDAR scanner designed to simplify spatial data capture for surveying, construction, and digital documentation projects. Using SLAM technology, it enables operators to scan indoor and outdoor environments while walking, generating detailed point clouds without repeatedly setting up a stationary laser scanner.

A distinctive advantage of the Trion S1 is its integrated field-to-office workflow. Operators can monitor scanning progress in real time through the FJD Trion Scan app, then process collected data using FJD Trion Model software for applications such as floor plan generation, 3D modeling, and site analysis.

With a portable design, interchangeable batteries, and optional accessories for colorized and georeferenced scanning, the S1 offers a practical solution for teams looking to expand their 3D reality capture capabilities.

Key Features

Walk-and-Scan SLAM Technology

The Trion S1 uses SLAM algorithms to capture surrounding geometry as the operator moves through a site. This approach reduces the need for repeated scanner setups and supports efficient data collection in buildings, corridors, underground spaces, and outdoor environments.

Real-Time Point Cloud Monitoring

Through the FJD Trion Scan app, users can view point cloud data during acquisition and check scanning coverage before leaving the site.

This immediate feedback helps identify areas requiring additional scanning and reduces the risk of incomplete field data.

Efficient Scanning with Portable Operation

The standard S1 features a 16-channel LiDAR sensor with a scanning rate of 320,000 points per second. Its wide scanning field of view supports spatial data capture across complex interior layouts and surrounding structures.

The scanner itself weighs approximately 1.8 kg, making it suitable for handheld operation and extended walking surveys.

Extended Field Operation with Dual Batteries

The hot-swappable dual-battery design supports up to four hours of operation under specified conditions.

For projects requiring longer data collection sessions, batteries can be exchanged without interrupting the power supply, helping field teams maintain a continuous scanning workflow.

Expandable Mapping and Processing Workflow

The Trion S1 can be paired with an optional panoramic camera for colorized point clouds and an RTK backpack configuration for georeferenced outdoor mapping.

Collected datasets can be processed through FJD Trion Model software for point cloud cleanup, modeling, measurement, and industry-specific analysis. Additional accessories and software modules may be required.

Applications

Building Surveys and Floor Plan Generation

The Trion S1 can capture interior spaces, rooms, corridors, and building structures for existing-condition documentation. Processed point clouds provide a foundation for floor plan creation, renovation planning, and Scan-to-BIM workflows.

Facility Digitalization

For industrial buildings, commercial properties, and facility management projects, the scanner helps document existing spatial layouts and accessible equipment areas.

The resulting 3D datasets can support asset documentation, facility planning, and digital modeling.

Construction Site Documentation

Construction professionals can use the S1 to record site geometry and monitor physical changes throughout a project. Its mobile scanning workflow is useful for capturing areas where conventional stationary scanning would require multiple setups.

Heritage and Architectural Recording

The S1 can capture the geometry of historical buildings, architectural features, and existing structures for digital documentation. Optional panoramic imagery can provide additional visual context for reconstruction and presentation.

Underground and Tunnel Surveys

SLAM-based data acquisition allows the scanner to operate in environments where satellite positioning is unavailable. Point cloud datasets can support tunnel documentation, cross-section analysis, and underground spatial assessment.

A Practical 3D Scanning Workflow from Field to Deliverables

The FJD Trion S1 brings together portable LiDAR acquisition, real-time scanning feedback, and dedicated point cloud processing software. Rather than focusing only on scanning hardware, the system provides an accessible workflow for collecting, reviewing, and transforming spatial data into useful project deliverables.

For surveying companies, construction teams, and reality capture professionals, the Trion S1 offers a flexible approach to everyday 3D documentation and mapping tasks.
