SISTEMA DE ADQUISICIÓN DE IMÁGENES MULTIESPECTRALES DE RAÍZ Y HOJA DE LECHUGA AEROPÓNICA EN INVERNADERO (AEROPONIC LETTUCE ROOT AND LEAF MULTISPECTRAL IMAGING SYSTEM IN GREENHOUSE)
Resumen
La finalidad de este trabajo es diseñar y construir un sistema de adquisición para capturar imágenes en el visible, en infrarrojo cercano e imágenes térmicas capaz monitorear la hoja y la raíz de lechugas aeropónicas. Se presenta un prototipo final diseñado para funcionar dentro de un invernadero tomando en cuenta las variables ambientales que podrían ser perjudiciales para el sistema como son: temperatura, humedad e iluminación. Además, se agregó una fuente de iluminación interna para mejorar el contraste en las imágenes capturadas en el infrarrojo cercano. Los resultados obtenidos muestran que las imágenes capturadas tienen la calidad adecuada para en un futuro poder obtener las características de crecimiento de la planta de lechuga.
Palabras clave: Aeroponía, Campo de visión, Infrarrojo, raíz, hoja.
Abstract
The purpose of this work is to design and build an acquisition system to capture images in the visible, near infrared and thermal images capable of monitoring the leaf and root of aeroponic lettuces. A final prototype designed to function inside a greenhouse is presented taking into account the environmental variables that could be detrimental to the system, such as: temperature, humidity and lighting. In addition, an internal light source was added to improve contrast in images captured in the near infrared. The results obtained show that the captured images have the adequate quality to be able to obtain the growth characteristics of the lettuce plant in the future.
Keywords: Aeroponics, Field of View, Infrared, Root, Leaf.
