GreenValley LiAir X4 Airborne Laser Scanning Unit

GreenValley LiAir X4: Autonomous LiDAR for High-Precision Mapping and Inspection

The GreenValley LiAir X4 is a lightweight, high-performance UAV LiDAR system built for professionals demanding reliable 3D data acquisition in the field. Engineered for autonomous operation, it combines a 32-line rotary laser scanner, a 26MP RGB camera, advanced inertial navigation, and SLAM integration for handheld missions. Whether mounted on a DJI M300/M350 RTK or used on the ground, the LiAir X4 delivers centimeter-level accuracy, dense point clouds, and intelligent flight planning-all in a compact, user-friendly design.

Designed for Powerline and Terrain Inspections

The X4's advanced AirPilot algorithm allows for intelligent autonomous flight, automatically identifying and crossing power line intersections, avoiding tree obstacles, and following rugged terrain using live DEM generation. Real-time tower logging, pole photography, and RGB imaging streamline inspections, while antenna-free GNSS integration with DJI drones simplifies setup. With full 360° x 270° scan coverage, this system excels in dense or difficult-to-reach corridors.

Maximum Flexibility, Minimum Downtime

LiAir X4's handheld SLAM capability ensures high-precision data capture even in GNSS-denied environments like under canopy, tunnels, or urban zones. Weighing only 1.44 kg (or 1.9 kg with the panoramic camera), it's designed for quick, plug-and-play deployment. Operators can view RGB point clouds in real time, choose from three display modes, and rely on long runtimes for extended operations. Its compatibility with multiple UAV platforms and robust software suite make it an ideal choice for full-spectrum inspection needs.
