Summary:Device and method for obtaining optimized multispectral images for the discrimination of materials. The invention describes a device for the selective illumination in wavelength of motifs, as well as a method that uses said device to obtain multispectral images using a monochrome camera. It consists of a set of light sources that are switched on individually and sequentially by a control system, while an artificial vision camera collects an image at each wavelength. The wavelengths included in the device are previously chosen after a spectroscopic study of the materials to be discriminated, these wavelengths having the characteristic of being the most suitable for a specific material discrimination task. The fundamental application of the invention focuses on the discrimination of materials through the artificial vision thereof.

La invención describe un dispositivo para la iluminación selectiva en longitud de onda de motivos, así como un método que usa el citado dispositivo para obtener imágenes multiespectrales utilizando una cámara monocroma. Consiste en un conjunto de fuentes de luz que son encendidas individualmente y de forma secuencial por un sistema de control, mientras una cámara de visión artificial recoge una imagen a cada longitud de onda. Las longitudes de onda incluidas en el dispositivo se escogen previamente tras un estudio espectroscópico de los materiales a discriminar, teniendo estas longitudes de onda la característica de ser las más adecuadas para una tarea de discriminación de materiales concreta. La aplicación fundamental de la invención se centra en la discriminación de materiales a través de la visión artificial de los mismos.
