High precision high frequency integrated airborne LiDAR survey system ARS-1000L with accuracy 15mm@150m and range 1350m
ARS-1000L airborne LiDAR survey system is a Riegl LiDAR based system and takes the UAV or other platforms as the carrier. It is developed and built by Wuhan Hi-Cloud Technology Co.,Ltd.After several years of continuous iterative upgrading, the system performance is stronger, the volume is lighter, the installation is more convenient and the operation is simpler.It has been recognized by the majority of users.
It integrates sensors such as high-precision laser, high-definition camera, GPS, MEMS inertial navigation and storage control unit. Supported by time synchronization technology of independent intellectual property and integrated multi-sensor integration technology, it synchronously obtains 3D laser point cloud, POS data and image data.
Typical application scenarios of ARS-1000L airborne LiDAR survey system
Main features of ARS-1000L airborne LiDAR survey system
1. High precision: under the measuring range of 150m, the ranging accuracy is better than 15mm; the absolute accuracy of the system is better than 5cm, which meets the needs of most application scenarios.
2. High frequency: the laser emission frequency of the system is 750000 points/s. High frequency LiDAR equipment can be equipped with UAVs with faster cruising speed. In the same time, more data can be obtained, which improves the data acquisition efficiency.
3. Long measurement range: the maximum range of LiDAR system is 1350m; long range measurement can improve the acquisition efficiency of the equipment and collect more point cloud data in the same time.
4. Multi platform: not only suitable for mainstream multi rotor UAV and VTOL fixed wing UAV, but also can be mounted on vehicle and backpack platforms for operation.
5. High integration: integrates the 3D laser scanner, POS module and fan into the hardware architecture; the overall weight is less than 4.5kg.
6. High safety: there is no gap between the rack and the system, which ensures the stability and reliability of the equipment; provides a proprietary lightweight anti-collision protective sleeve to provide certain physical protection for the equipment and reduce unnecessary damage; the loss prevention module is optional.

Wind farm survey in mountain area
The survey area is mainly mountainous terrain. The average elevation in the wind farm survey area is high, and the altitude drop in some areas of the measurement area is over 300 meters. The whole wind farm covers an area of about 12 square kilometers. The vegetation is subtropical evergreen broad-leaved forest, with large vegetation coverage rate and various types.
The terrain of the survey area is complex, the altitude difference is large, the traffic is inconvenient, the climate environment is bad. There are several wind turbines with a height of more than 100 meters in the survey area, so it is difficult to design the route. The line of sight is blocked seriously, and it is difficult to locate the take-off point.
The project adopts ARS-1000L airborne laser measurement system. Three takeoff and landing points are selected in the whole survey area for a total of seven sorties.
