Metodología para el procesamiento de la información de un levantamiento con escáner láser en puentes tipo Transmilenio

Abstract

Technological advances have given a noticeable boost for BIM construction (Building Information Modeling) on the engineering and architecture fields. Therefore, a number of inconveniences have been resolved when delivering documentation of technical type, applying and exchanging digital representations and facilitating the interpretation of a building life cycle. Terrestrial laser scanners are employed in numerous engineering fields due to their obtained accuracy and different available uses. There is a high potential for these scanners, it permits to retrieve coordinates from every surrounding surface in a matter of minutes, without the need of any contact with the measured elements. This document focuses on facilitating the data processing methodology for a topographic survey made with laser scanner on pedestrian bridges. Different types of software allow edition in order to generate a 3D model to be used and exchanged on the engineering and architecture fields, being this the base point for the BIM methodology. In addition, an analysis and research of the structure and georeferencing systems for the received data (Point cloud) is made. Thus, it can be used adequately, without causing any deterioration or damage. This paper consists of two chapters for its development. The first one will be the theoretical framework stage where research in regards to the project is found. The second one will be the methodological stage where the project procedure is detailed in a structured way
