What devices are compatible with the FJD Trion V4e LiDAR Kit?
The FJD Trion V4e LiDAR Kit only supports iOS devices, specifically iPhone 15 and later models. Android smartphones are not compatible at this time. Please confirm your iPhone model before purchasing to avoid compatibility issues.
What is included in the package? Does it come with a smartphone or RTK receiver?
The package includes:
- 1 x FJD Trion V4e LiDAR Scanner main unit
- 1 x FJD Trion Model Permanent Activation Code (Standard Edition)
- 1 x Charging cable
Important notes:
- Smartphones shown in product images are for illustration only and are not included.
What is the difference between V4e LiDAR and V4e Pro LiDAR?
The only difference is the RTK receiver. The V4e LiDAR comes with a standard RTK, while the V4e Pro LiDAR is equipped with a Pro RTK receiver, which supports laser range finding and tilt measurement.
What is the difference between real-time point cloud accuracy and post-processed accuracy?
- Real-time point cloud accuracy: 5 cm. This is the accuracy of point cloud data displayed and captured in real time via the FJD Trion Scan App, suitable for quick on-site verification.
- Post-processed point cloud accuracy: 3 cm. This is the higher accuracy achieved after processing the captured data with the FJD Trion Model software, ideal for professional scenarios like construction BIM or topographical surveys that require precise results.
Can the LiDAR Kit work both indoors and outdoors? What setup is needed for each scenario?
Yes, it supports both indoor and outdoor use with two flexible setups:
- Outdoor (high-precision)
Smartphone + V4e Mini RTK Receiver + LiDAR Scanner
- Indoor (no GNSS signal)
Smartphone + LiDAR Scanner
How long is the battery life, and how long does it take to charge?
- Battery life: ≥ 5 hours of continuous operation (under 25℃, without external accessories like the RTK receiver). This is sufficient for a full day of on-site scanning.
- Charging time: ≤ 3 hours when using a 5V/3A charger (charger not included; please use a compatible charger to avoid damaging the battery).
What software do I need to use with the FJD Trion V4e LiDAR Kit? Are they free?
You will need three core software tools, all of which are free to use (with the included activation code):
- FJD Trion Scan App: For real-time scanning, point cloud preview, and data capture. Available for download from the Apple App Store.
- FJD Trion Model: For advanced data processing (e.g., generating 3D models, analyzing data for construction/forestry/BIM). Downloadable from the FJDynamics official website; requires the included activation code to unlock full features.
- FJD Trion Explorer: For team collaboration (e.g., uploading point clouds, secure sharing, collaborative editing). A free trial is available, with details on long-term access provided on the platform.
Does the LiDAR Kit support 3D Gaussian Splatting (3DGS)? How to generate 3DGS representations?
Yes, it supports high-quality 3D Gaussian Splatting. To generate 3DGS representations:
- Capture point cloud data with the FJD Trion V4e LiDAR Kit (ensure sufficient coverage of the target area).
- Import the captured data into the FJD Trion Model software.
- Use the built-in 3DGS module to process the data—this will efficiently generate immersive 3D Gaussian Splatting representations for visualization or presentation.
Is the LiDAR Scanner eye-safe? What is its laser safety rating?
Yes, it is eye-safe. The laser wavelength is 905nm±15nm, and it meets the CLASS 1 eye safety standard(IEC 60825-1:2014). This means it poses no risk of eye injury during normal use, even with accidental exposure.
