The system for building monitoring has been described in Springer’s Journal of Civil Structuring Health Monitoring.
The title of the article is Use of digital image processing in the monitoring of deformations in building structures. The article describes the system in detail, which was jointly developped by TUM (Technical University Munich), HSK (High School Karlsruhe) and Impuls. The system establishes a cost effective solution to monitor roof deformations of buildings.
