GreenValley LiAir X4 Autonomous UAV LiDAR Data Acquisition System
LiAir X4 is GreenValley International’s latest generation autonomous LiDAR data acquisition system. It features a lightweight 32-line rotary laser scanner, high-precision inertial navigation system, a high-resolution camera, and a powerful edge computing platform. With 360-degree scanning and the self-developed AirPilot autonomous flight algorithm, it enables efficient, safe, and cost-effective smart inspections with autonomous obstacle avoidance.
Fully Autonomous Obstacle Avoidance Flight
Multi-Platform Compatibility (Airborne/Handheld)
300 m Maximum Measurement Range
5 cm Elevation Accuracy (@100 m)
Autonomous Flight Function
Above Powerline ...
Automatic line intersection identification, autonomous crossing of intersections, real-time tree obstacle reporting and pole/tower log generation, and automated pole/tower ...
Side Powerline ...
Capture RGB photos of conductors, autonomous tower crossing and line switching.
Real-time Terrain
Real-time DSM construction for terrain-following flight, meet the demand of large height difference terrain data collection for short-range LiDAR system.
Omnidirectional Scanning
Powered by the self-developed high-precision integrated motor, the scanner achieves 360°x 270° omnidirectional scanning. Enhanced point cloud completeness in dense vegetation areas and vertical structures (buildings and bridges), with finer 3D structural reconstruction.
Support GNSS Antenna-Free Solution, Simplifying the Installation Process
When mounting X4 on DJI M300/M350 RTK aircraft, there is no need to install external antennas, yet it can still acquire high-precision GNSS information. After post-processing software, a centimeter-level high-precision point cloud can be generated.
GreenValley APP: New design, Focusing on Work Quality
The APP supports real-time viewing of true color point clouds and 720P/30FPS video stream. This allows the flight personnel to clearly view the surrounding environment and better evaluate the point cloud quality.
Support Handheld Mode
Optional handheld kit with two configurations (Standard/Panoramic Camera Edition).
By combining GNSS and LiDAR SLAM algorithms, it enables reliable point cloud collection even in GNSS-denied environments and supports 3DGS model generation.
One device, multiple applications—maximize versatility and performance all-in-one solution.
