Potencial Uso De Câmera Termal Acoplada a Vant Para Monitoramento De Culturas

Abstract: RESUMO A máxima produtividade da lavoura é alcançada em condições ideais de cultivo. Em busca do ambiente ideal, se faz necessário o manejo e monitoramento constante da área cultivada, haja vista a possibilidade de ataque de pragas e doenças, além de estresse por falta de água e nutrientes. O monitoramento constante, se feito de forma manual é extremamente oneroso e demorado, além de obtendo informação muitas vezes tardias a respeito de algum problema existente. Estudos mostram que o uso de VANTs acoplado a se… Show more

“…Analyzing benefits related to these two topics motivates a combination of their functionalities to obtain mutual benefits (Entrop & Vasenev, 2017). A thermal camera integrated with an UAV is an important tool to evaluate large areas in an automated way and in reduced runtime (Viana et al, 2018). Main challenges for this technology are low resolution of some thermographic cameras, regulations that limit operations involving UAV on a visual line and high dependence on climate (Witczuk et al, 2017).…”

“…Isto leva ao aumento da temperatura em partes localizadas, tal como as folhas. Diante disto, imagens geradas por câmeras térmicas constituem uma forma de detectar presenças de infecção por patógeno ainda não visível a olho nu (VIANA et al, 2018;VIANA et al, 2019). Ruiz et al (2013), estudando uma nova abordagem de imagens aéreas de alta resolução para detecção da Huanglongbing (HLB) ou doença do greening dos citros, usando um veículo aéreo não tripulado (VANT) de sensor remoto de baixa altitude e multirotor de baixo custo, observaram que dentre os algoritmos de classificação testados, a máquina de vetores de suporte (SVM) com kernel resultou em melhor desempenho do que outros métodos como SVM (linear), análise discriminante linear e análise discriminante quadrática e concluíram que, o sensoriamento aéreo de alta resolução tem boas perspectivas para a detecção de árvores infectadas com HLB.…”

“…Studies in the literature show that plants after being attacked by pathogens suffer damage that causes changes in the rate of transpiration and flow of water throughout the plant or in organs. This leads to increased temperature in localized parts of the plant, such as leaves [20,21].…”

“…The acquisition cost of a thermographic, multispectral and hyperspectal camera is high, especially in countries not benefited by the local currency. This makes it difficult for many research centers around the world to carry out research and development in many areas that could leverage technology to improve their research and make new discoveries [21]. Table 1 presents summarizes most studied research fields with emphasis on the use of optical sensors for the monitoring of agricultural crops and agricultural processes.…”
