The range accuracy of 15mm airborne LiDAR survey equipment ARS-200 with the middle range of 330m

ARS-200 airborne LiDAR survey equipment is a Riegl LiDAR based system. It is developed and built by Wuhan Hi-Cloud Technology Co.,Ltd. It integrates sensors such as high-precision laser scanner, HD camera, GPS, MEMS inertial navigation module 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.

Thanks to the advantages of light weight, convenient transportation and high efficiency of results processing, the system is widely used in various application fields such like emergency mapping, topographic mapping, power line inspection, highway survey, coastal reef survey, excavation and filling volume calculation, archaeological survey and mapping and so on.

System advantages:

1. Only 2.5kg, it improves the operation efficiency of the carrier platform.

2. The waterproof and dustproof grade of the system is better than IP64.

3. Multi platforms, like UAV, automobile and backpack.

4. Screw free rapid installation, greatly reduce the installation and deployment time on site.

5. Max. 330m range can meet the survey requirement in the plain area.

Application project of highway survey

1. Project Overview: The main line of the project is about 8km long. The survey area is mainly mountainous terrain, with an average altitude of 600m. The river crosses the survey area, and the altitude drop in some areas is large. The vegetation in the survey area is lush, mostly evergreen broad-leaved forest and low shrubs.

2. Project Requirement: The main task of the project is airborne LiDAR survey and point cloud processing of the certain section of the highway. The mean square error of point cloud elevation is required to be less than 15 cm.

3. Project Difficulties: The traditional surveying and mapping operation is more dangerous because of the traffic on the highway. It is difficult for GNSS receiver to receive satellite signals due to dense vegetation and large altitude drop in the survey area.

4. Solution and Result: ARS-200 airborne LiDAR survey system is applied in this project. After trajectory calculation, point cloud combine and other data processing processes, the point cloud result is as follow:
