Abstract

At present there is a lack of commercial software packages able to perform differential temperature gradient analysis. This is an innovative and fundamental tool to speed up the recognition of thermal anomalies revealing finishing damages like detachments. This paper presents a photogrammetric methodology aimed at mapping IR thermal images on 3D models created with terrestrial laser scanning technology. The attention is focused on building, where a standard RGB texture of the 3D model will coupled to temperature values. Each facade will be then transformed into an orthophoto and processed in a GIS environment to support new thermal analysis. The developed image processing pipeline will be illustrated starting from data acquisition up to data visualization and management.
