Automated Inspection Method of Ordinary Arterial Highway Illegal Construction Based on Vehicle-Mounted Laser Point Cloud
摘要
Abstract
To achieve efficient and accurate inspection and management of ordinary arterial highway ille-gal construction,ensuring traffic safety and improving transportation efficiency,an automated inspection method of ordinary arterial highway illegal construction based on vehicle-mounted laser point clouds was proposed.Firstly,a hybrid road edge extraction algorithm was constructed based on the fusion of two-dimensional and three-dimensional features.Secondly,the point cloud clustering technology based on GB-ADBSCAN was adopted to identify illegal construction point cloud as a whole,and the Point-Net++model was improved by adjusting the number of features and introducing parallel symmetry function to segment the single illegal construction,achieving the accurate inspection of illegal con-struction in sheltered environment.Finally,the proposed method was verified using laser point cloud data from national highway G207 in Henan Province.The results show that the proposed hybrid road edge extraction algorithm has an extraction accuracy of 98.7%,and the extraction effect was signifi-cantly better than that of three commonly used road edge line extraction methods based on scanlines,feature images and spatial features.As verified by field surveys and real-scene image comparison,the accuracy of unauthorized construction identifying based on vehicle-mounted laser point clouds reaches 87%,indicating that the proposed method can effectively improve the recognition accuracy and speed of the point cloud of illegal construction,and achieve stable and efficient automated inspection of high-way illegal construction under the complex environment of roadside.关键词
