Keywords: UAV, LiDAR, Mapping, Urban, Modelling, Classification
Abstract. This paper presents urban mapping and modelling utilizing a low-cost Unmanned Aerial Vehicle (UAV) mounted Light Detection and Ranging (LiDAR) systems. Urban environments pose unique challenges for traditional mapping techniques due to their complex and dynamic nature. The integration of UAVs and LiDAR technology offers a versatile solution capable of capturing highly detailed and accurate 3D data in urban settings. The proposed system combines state-of-the-art UAV platforms with advanced LiDAR sensors to acquire high-resolution point cloud data over urban areas. The UAV platform provides the necessary flexibility and agility to navigate densely populated areas while capturing data from various perspectives. The LiDAR sensor, with its ability to accurately measure distances and capture fine details, enables the creation of detailed 3D models with precise geometric information. This research demonstrates the effectiveness of the urban modelling approach through UAV-based LiDAR mobile surveying and mapping conducted in urban environments of a case study area in Sultan Qaboos University. The results show the ability of the system to accurately map complex urban structures, including buildings, roads, and vegetation, with high levels of detail and accuracy. Overall, this research contributes to the advancement of UAV-based remote sensing technologies for urban mapping and modelling, offering new opportunities for capturing comprehensive and actionable data for various applications in urban environments.
