Recently, Terrestrial Laser Scanners (TLS) have received considerable attention for their potential applications in forest management, archaeology, ecology as well as remote sensing and urban planning applications. The TLS systems differ from Airborne Laser Systems (ALS) in that they do not utilise an integrated Global Positioning System (GPS) and Inertial(More)
Accurate modelling of individual trees is essential for forestry applications e.g. forestry inventory and biomass estimation. This paper aims to utilise Terrestrial Laser Scanners (TLS) in order to derive a three dimensional (3D) tree structure and compute its volume. A new approach is proposed and tested to estimate the tree structure and leaf area using(More)
Various methods have been developed to measure three-dimensional (3D) objects and obtain a high-accuracy Digital Surface Model (DSM). High-quality elevation data is essential to support urban planning and civil engineering, however, effective measuring of height information is still challenging. The aim of this paper is to present an accuracy assessment of(More)
Three dimensional (3D) mapping has been used widely in the spatial industry as a powerful technique for rendering artificial objects and their surrounding topography. However, an accurate and effective 3D modelling of complex features e.g. feature rich buildings and trees, is still challenging. The aim of this study is to develop an efficient framework to(More)
