Resumen
Esta investigación presenta una metodología técnica para usar aparatos UAV / RPAS (Unmanned Aerial Vehicle / Remotely Piloted Aircraft System) de bajo costo, misma que se constituye en una herramienta importante en la investigación de Estabilidad en Taludes, usando información del entorno espacial y temporal a partir de varias imágenes verticales y oblicuas, de esta manera se obtiene procedimientos eficientes en menores tiempos y con mayor precisión que las habituales. Para ello se realizó una investigación sobre los tipos de UAV´s que existen en el mercado, sus ventajas, desventajas y la forma correcta de usarlos, con el objetivo de realizar una descripción paso a paso de su proceso y postproceso, convirtiéndose en una tecnología eficiente dentro del campo de la Ingeniería Geotécnica. Para esta investigación se usaron dispositivos de tipo multi-rotor, el propósito fue realizar fotogrametría digital y obtener resultados eficientes y precisos para el estudio y evaluación de estabilidad de taludes, además se realizó varios vuelos de investigación de fotografías aéreas verticales y oblicuas, mismas que fueron procesadas en los softwares fotogramétricos Pix4d Mapper y Agisoft PhotoScan, de esta manera se descifró las aplicaciones que nos brinda esta tecnología al momento de levantar información del área inestable en estudio, estos resultados se obtuvieron en base al macro deslizamiento activo “Cachi”, ubicado en Ecuador, Provincia del Cañar, Cantón el Tambo. Por último, se realizó una investigación sobre la visión del entorno físico del mundo real, llamada Realidad Aumentada (RA), el propósito es el de presentar una propuesta de difusión para posteriores trabajos sobre deslizamientos
Abstract:This research presents a technical methodology to use low cost devices UAV/RPAS (Unmanned Aerial Vehicle/ Remotely Piloted Aircraft System), which constitutes an important tool in the investigation of slope stability, using spatial and temporal information from several vertical and oblique images, in this way efficient procedures are obtained in shorter times and with precision that usual. For this purpose, an investigation was carried out on the types of UVA’s that exist in the market, their advantages, disvantages and the correct way to use them, with the aim of making a description step by step of its process and post process, becoming an efficient technology within the field of Geotechnical Engineering. For this research, multi-rotor type flying devices were used, the purpose was to perform digital photogrammetry and obtain efficient and accurate results for the study and evaluation of slope stability in addition, several research flights of vertical and oblique aerial photographs were carried out, which were processed in the photogrammetric software Pix4dMapper and Agisoft PhotoScan, in this way the applications that this technology gives us when deciphering at the moment we gather information from the unstable area under study, these results were obtained based on the ¨Carchi¨ active sliding macro, located in Cañar province, El Tambo town, Ecuador. Finally an investigation was carried out on the vision of the physical environment of the real world, called augmented reality (RA), the purpose is to present a dissemination proposal for subsequent work on landslides.
