Underground mining creates goafs, impacting resource extraction and safety. To address the issues of low efficiency and high reliance on manual operations in traditional techniques, this paper proposes a goaf scanning and modeling system (GSMS) for underground mine based on a quadruped robot. This system performs three-dimensional modeling of goafs...

Simultaneous Localization and Mapping (SLAM) is one of the key technologies in robot navigation and autonomous driving, playing an important role in robot navigation. Due to the sparsity of LiDAR data and the singularity of point cloud features, accuracy loss of LiDAR SLAM can occur during point cloud matching and localization. In response to these...
TCC (graduação) - Universidade Federal de Santa Catarina, Campus Blumenau, Engenharia de Controle e Automação. / Este trabalho aborda a aplicação da tecnologia LIDAR para escaneamento de ambientes internos em 3D, apresentando um protótipo integrado com componentes eletrônicos controlados por algoritmos. O estudo envolve a construção do sistema, inc...
Point cloud modeling of rock slopes using LIDAR and Structure-from-Motion digital stereophotogrammetry provides,at a minimum, thousands of facets and facet normals that can be used to identify the densities of orientations of rock massdiscontinuities, the geometries of potentially removable blocks, and the character of the excavation face. As part ...
Tato práce se zabývá vývojem algoritmů pro vytváření modelů stromů z dat LIDARu. V práci je navržen postup pro odstranění země a pro detekci kmene stromu a na něj navazujících větví. Algoritmus pracuje s reálnými daty z experimentu se 400 let starými duby letními stojícími na hrázi rybníka Homolka v Praze. Z pořízených dat byl vytvořen graf modeluj...
The nature of the post-fire natural renewal of the forest in the cuttings in the pine forests of the Ulyanovsk region has been studied. It was found that in 1917 (1 year after the grass-roots fire) and in 2023, birch self-seeding prevailed in natural reforestation in the cuttings of burnt forest and raw-growing forest. In addition, in both accounti...
The article discusses the process of changing attitudes towards the use of a car that provides freedom of movement. Now freedom of movement consists in having your own car. In the future, freedom of movement will turn into a service that will be provided by the operator. The advantages of using self-driving cars are given. / В статье рассмотрен про...
L’écologie historique requiert une approche multi-disciplinaire, pour laquelle quelques considérations méthodologiques sont ici abordées, notamment pour percer les secrets de l’histoire holocène des forêts. L’apport de la technologie lidar est plus particulièrement détaillé. Un nombre croissant d’outils, de jeux de données et de datations permet dé...
Tato práce je věnována porovnání několika technik estimace jízdních pruhů s různými modely geometrie vozovky za využití veřejně dostupných dat z LIDARu a kamer. Za tímto účelem byl vyvinut celý framework pro zpracování dat a vyhodnocování chyb. Znalost toho, jak se prezentované metody chovají za konkrétních okolností a jaké jsou ve srovnání mezi se...
Terrestrial laser scanning (TLS) has been adopted as a feasible technique to characterize tree stems while the characterization of trees’ branching architecture has remained less explored. In general, branching architecture refers to the spatial arrangement of branches and their characteristics that are important when exploring the eco-physiologica...
