Mejoramiento a la metodología de procesos lidar con enfoque topográfico implementados en levantamientos de estructuras de viaductos en Italia

Abstract

This thesis focuses on the application of vectorization techniques based on LiDAR technology for the generation of high-precision three-dimensional models. Vectorization has become a fundamental tool in various disciplines, including cartography, civil engineering, and land management, due to its ability to capture the geometry of objects and terrain in detail. This technical report shows the development of the internship, which was carried out under the supervision and review of Eng. Nicolas López. The interns presented technical contributions to improve the processes for handling LiDAR information at the facilities offered by the company GRS Colombia. The document presents the results obtained in each of the projects focused on road structures using LiDAR technology, where new methodologies were implemented to improve the products and quality of the results. First, the processes implemented by the company in the calculation and vectorization of the projects presented previously were studied, in order to identify the advantages and disadvantages of these processes and their results. Subsequently, effective methodologies are studied in terms of improving quality and reducing production time, which help to further reduce the disadvantages found and thus achieve reliable results. The final results are presented in the Civil3D software. In total, during the students' internship, which lasted 384 hours, according to the internal regulations of the Universidad Distrital Francisco José de Caldas, 3 projects of these characteristics were carried out. Finally, the results obtained by the interns and the recommendations are presented. Once this is completed, the work of the interns is considered finished.
