Application Project:

Highway survey project -- ARS-200 UAV LiDAR System

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.

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.

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.

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