High Accuracy 15mm@150m UAV LiDAR Sensor System ARS-1000L For Topographic Mapping

High accuracy of 15mm@150m long range 1350m UAV LiDAR System ARS-1000L with high frequency of 750000 points per second

Developed and built by Wuhan Hi-Cloud Technology Co.,Ltd, ARS-1000L UAV LiDAR system is a Riegl LiDAR based system with high level integration. It integrates sensors such as high-precision laser, high-definition camera, GPS, MEMS inertial navigation and storage control unit and synchronously obtains 3D laser point cloud, POS data and image data.

The system has the advantages of light weight, convenient transportation and high efficiency of results processing. It is a multi platform system, usually takes UAV as the carrier. It could also adopt other mode like vehicle mounted or backpack mode,  to complete tasks in different application scenarios. Therefore, the system is widely used in emergency mapping, topographic mapping, power line inspection, highway survey, coastal reef survey, excavation and filling volume calculation, archaeological survey and mapping and other fields.

Advantages of ARS-1000L UAV LiDAR System

i. Long range -- The maximum range of LiDAR system is 1350m@60%. Long measurement range can improve the acquisition efficiency of the equipment and collect more point cloud data in the same time.

ii. High precision -- The ranging accuracy is better than 15mm under the measuring range of 150m. The absolute accuracy of the system is better than 5cm, which meets the needs of most application scenarios.

iii. High frequency -- The laser emission frequency of the system is 750000 points/s. It can better reflect the landform in the survey area and obtain more fine point cloud data. In addition, high frequency LiDAR equipment can be equipped with UAV with faster cruising speed.

iv. High integration -- The system integrates the 3D laser scanner, POS module and fan into the hardware architecture, the overall weight is less than 4.5kg. 

v. Multi platform -- It is suitable for mainstream multi rotor UAV and VTOL fixed wing UAV, and also can be mounted on vehicle and backpack platforms for operation. The system is equipped with corresponding installation firmware to meet the rapid installation and deployment on the operation site.

vi. High safty -- The system has high stability and reliability. The system also provides a proprietary lightweight anti-collision protective sleeve to provide certain physical protection, and the loss prevention module is optional.

Application project of ARS-1000L UAV LiDAR System

Wind farm survey in mountain area

Project Overview

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.

Project Difficulties

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.

Solution

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.
