Resumen
Descripción
Los vehículos aéreos no tripulados (UAV) se usan actualmente para múltiples aplicaciones en múltiples campos: silvicultura, geología, sector ganadero y seguridad. Entre las aplicaciones más comunes cabe destacar la adquisición de imágenes, el riego, el transporte, la vigilancia, entre otros. Las imágenes adquiridas hasta los últimos años han estado utilizando satélites, sin embargo, debido a los altos costos que se incurren y el bajo acceso a estas tecnologías, los UAV se han convertido en una herramienta para mayor precisión y alcance para la toma de decisiones en la agricultura. La investigación que se presenta, trata de las implementaciones que se realizan mediante imágenes aéreas adquiridas con UAVs dirigidas a cultivos. La información de las bases de datos de revistas internacionales, grupos y centros de investigación se toma para determinar el estado actual de las implementaciones en Precision Agriculture (PA). Este artículo describe tareas tales como: preparación del suelo; límites y áreas de tierra, monitoreo de vegetación; clasificación de la vegetación, crecimiento, altura, estado fitosanitario; manejo de enfermedades, plagas y malezas, fertilización e inventarios desarrollados a partir del análisis de imágenes aéreas adquiridas con UAVs.
Unmanned Aircraft Vehicles (UAVs) are currently used for multiple applications in various fields: forestry, geology, the livestock sector and security. Among the most common applications, it is worth to stand out the image acquisition, irrigation, transport, surveillance and others. The study that one presents treats of the implementations that are realized by means of aerial images acquired with UAVs directed to the farming. Images acquired until recent years had been using satellites, however due to the high costs that are incurred and low accessibility to these technologies, UAVs, have become a tool for greater precision and scope for making decisions in agriculture. Information from databases of international magazines, groups and research centers is taken to determine the current state of implementations in Precision Agriculture (PA). This article describes tasks such as: soil preparation; limits and land areas, vegetation monitoring; classification of vegetation, growth, height, plant health; diseases management, pests and weeds, fertilization and inventory developed from analysis of aerial images acquired with UAVs.
