SYSTEM AND METHOD OF CAPTURE OF MULTI-PECTRAL IMAGES FOR THE DISCRIMINATION OF MATERIALS.

A system for capturing multispectral images for the discrimination of materials, comprising: a plurality of light sources (1) to emit different wavelengths and configured to be turned on and off by a control system (7) and to illuminate an object (2) from whose materials it is desired to obtain a multispectral image; a vision camera (5) comprising a two-dimensional image-forming sensor. The system comprises a diffusing surface (3) located between the chamber and the assembly formed by the light sources (1) and said object (2). The diffusing surface (3) comprises an opening (4) through which said chamber (5) is able to capture an image of said object (2), and where the relative arrangement between the light sources, the camera and the diffusing surface allows to avoid the capture by the camera of non-diffuse specular reflection. A method of capturing multispectral images for the discrimination of materials. (Machine-translation by Google Translate, not legally binding)
