모의 분사 시스템을 이용한 농업용 드론의 저비용 분사성능 평가 방안

Abstract

In recent years, unmanned aerial vehicles (UAVs) also known as drones have been employed in an agricultural field. Although spray systems have been well developed for general agricultural applications, there are no researches about the spray system for the agricultural drone. In addition, high cost is required to evaluate the spray performance of agricultural drones. In this study, we developed a simulated spray system and an evaluation method for the spray performance of agricultural drones. With a digital image processing, the spray performance was evaluated based on the coefficient of variation and the effective spraying width was calculated. The developed system was verified by on-site test using an evaluation method similar to Foundation of Agricultural Tech Commercialization and Transfer (FATCT). The results of the developed system agree well with that from a field test. The developed system would be useful for designing and evaluating spraying systems for agricultural drones.
