LiEagle

Helicopter 3D Mapping System

LiEagle is an aerial Lidar surveying system designed for large-area and long-range 3D data collection projects. The system is designed to be mounted to a helicopter platform. It features a Riegl VUX-1LR laser scanner coupled with a best-in-class inertial measurement unit (IMU) for increased point cloud accuracy and precision.

Description

The LiEagle is well-suited for projects aiming to map terrain features beneath forest canopies and extract structural parameters from forest Lidar data. The centimetre-level accuracy of this measurement device will meet the rigorous accuracy demands of civil engineering and critical infrastructure maintenance professionals. And an optional high-definition (50 megapixels) digital camera module can be used to generate photogrammetry products and true colour 3D point clouds during each Lidar survey.

System Accuracy

At a flight-height (AGL) of 200 meters, the LiEagle system can generate 3D point clouds with absolute horizontal and vertical accuracies that are less than 10 cm.

Acquisition Software Supports Real-Time Navigation

GreenValley International delivers custom acquisition software with its LiEagle system, which supports the importation of .kml & .xls formatted flight routes and a real-time flight status display for users to monitor during data collection. This easy-touse programme also allows operators to correct flight attitude-induced errors and thereby improve the quality of Lidar data collected.

The LiEagle supports a 45° inclination angle installation, which holding other operating conditions constant, will increase point cloud density by more than 30% (compared to a 0° inclination angle installation). This feature makes LiEagle particularly useful to those seeking to survey powerline assets and corridors while collecting high quality (complete) transmission tower point cloud data.
