Abstract
SISTEMA E MÉTODO DE DETECÇÃO DE CONCENTRAÇÃO DE PLURALIDADE DE RESÍDUOS QUÍMICOS EM UM PRODUTO AGRÍCOLA. Trata-se de um método implementado por processador para detectar uma concentração de pluralidade de resíduos químicos em um produto agrícola. O método inclui (a) receber, por um dispositivo hiperespectral, um conjunto de dados associado a uma ou mais medições de refletância do produto agrícola; (b) determinar dados associados a uma pluralidade de bandas; (c) reiterar dinamicamente as etapas (a) e (b) em intervalos de tempo predeterminados para obter um conjunto de dados treinado; (d) determinar comprimentos de onda relevantes entre os conjuntos de dados treinados, selecionados com base em uma técnica de seleção de recurso para formar uma matriz de emissores; (e) calibrar, pela matriz identificada de emissores, para emitir luz na região de detecção de uma ou mais amostras do produto agrícola para obter dados associados à refletância e transmitância; e (f) calcular um índice de calibração com um sinalizador de desmultiplicação para detectar a presença ou ausência da pluralidade de resíduos químicos no produto agrícola.
