Overview
JoLiDAR-LR22S is a multi-functional and long-range LiDAR scanning system that has a long endurance, high measurement accuracy, and fast data processing speed. It integrates a laser scanner, GNSS high-precision positioning system, Lrg guidance system, high-speed data acquisition, and storage system, and full-frame camera.
Benefits and Features
This drone-based LiDAR scanner features a full 360° field view and laser pulse repetition rates of up to 1500 kHz, and integration of a full-frame camera, which is ideal for challenging UAV applications such as measurement of inaccessible canyons and open-pit mines.
Capture Synchronized Point Clouds and Orthophotos
LR22S simultaneously captures centimeter-level precision point clouds and 61M orthophotos, significantly improving the efficiency of data acquisition.
Detection Range of 1854m, 100% Eye Safe
Thanks to the advanced 1550nm wavelength, LR22S has a detection distance of 1845m or further. It lets this device overcome flight altitude constraints, reducing operational difficulties.
Higher Point Cloud Density
With 1500 kHz laser emission frequency and 1.5 million points/sec measurement frequency, LR22S gives you higher density laser point clouds and a more accurate detailed picture of your object.
Improved Penetration of Dense Vegetation
The device provides 15 echoes that can penetrate dense vegetation and obtain detailed topographic data, making it the best solution for mapping mountainous areas.
High Point Cloud Accuracy
LR22S integrates a high-precision laser scanner and navigation system which ensures the vertical accuracy better than 3cm and horizontal accuracy better than 5cm.
High-resolution 3D Models
With an angular resolution of less than 0.001°, LR22S helps create finer and clearer 3D point cloud models, allowing to easily check small objects at a distance.
GCP-free, Save Manpower
Integrated with JOUAV drones, it automatically calculates location information without Ground Control Points. Just one person can complete the entire process of data collection.
360° Field of View
LR22S has a field of view up to 360°. There is no need to join multiple products in order to obtain a large field.
Data Results
Obtaining laser point cloud and orthomosaic map at the same time, the laser scanner can quickly generate a raw point cloud, 3D point cloud, high-precision DEM, DSM, DOM, and DLG.
