D3.3 – Hyperspectral material
Creators
Description
This report encapsulates an exploration of hyperspectral imaging technologies for material identification processes in construction settings. The initial focus on sensor selection involved an in-depth investigation of the MicaSense RedEdge multispectral sensor. Unforeseen challenges led to a strategic shift, leveraging the available FX10 hyperspectral camera by Specim. The subsequent data acquisition phase covered the acquisition setup, software utilization, and the systematic creation of a dataset featuring diverse construction materials. Data analysis encompassed detailed preprocessing steps, including calibration and specific bands selection to replicate the data that would have been acquired with the initially considered RedEdge multispectral sensor. A Principal Component Analysis unveiled underlying patterns within the dataset, highlighting distinctive spectral signatures of different construction materials.
