[ES] Las infestaciones de malas hierbas precisan del uso de herbicidas para controlar la calidad y el rendimiento de los cultivos. Aunque las malas hierbas con frecuencia se distribuyen en rodales o agregados, la práctica más extendida es la aplicación de herbicidas en todo el cultivo, resultando en un aumento de los costes. El control localizado de malas hierbas se hace mediante muestreos en campo, detección próxima o teledetección. En este último caso es necesaria la obtención de mapas de emergencias de malas hierbas en fases fenológicas tempranas para utilizarlos para su control en post-emergencia. Las imágenes remotas de aviones pilotados o satélites no son útiles debido a su baja resolución espacial y temporal. Sin embargo, este no es el caso de los vehículos aéreos no tripulados. Este artículo presenta un nuevo método para monitorización de malas hierbas mediante este tipo de plataformas, mostrando resultados prometedores.
[EN] Usually, weed-infested crops require the use of herbicides as a useful manner of controlling the quality and quantity of crop production. Although there are weed-free areas, the most common approach is to broadcast herbicides entirely over crops fields, resulting in a potential reduction of profits. Recently, patch spraying has allowed the application of site-specific weed management by using precise and timely weed maps at very early phenological stage obtained either by ground sampling or proximal or remote sensing. Remote imagery from piloted planes and satellites are not suitable for this purpose given their low spatial and temporal resolutions; however, unmanned aerial vehicles (UAV) represent an excellent alternatuve. This paper presents a new classification framework for weed monitoring via UAV showing promising results and accurate generalisation in different scenarios.
