Article Synopsis
- * The camera setup employs a scanning Fabry-Pérot interferometer and records data to distinguish between twelve different plastic types when heated to 60 °C.
- * A nine-component principal component analysis combined with a k-nearest neighbors model achieves high accuracy, with a 90% micro precision and 99% macro specificity, successfully classifying most plastic types except for ABS.
Determination of the surface temperature of different materials based on thermographic imaging is a difficult task as the thermal emission spectrum is both temperature and emissivity dependent. Without prior knowledge of the emissivity of the object under investigation, it makes up a temperature-emissivity underdetermined system. This work demonstrates the possibility of recognizing specific materials from hyperspectral thermal images (HSTI) in the wavelength range from 8-14 µm.
