The Subsurface dynamic thermographic procedure has been applied in a wide range of industries, yet; the static applications are still limited to Predictive Plant Maintenance PPM qualitative routines. This work is concerned with the development of a quantitative static thermographic application, which is intended to evaluate the coverage of automotive protective coat applied on steel substrates. This developed system is an automated replacement for subjective inspection procedures, in contrast to currently applied methods, provides repeatable and precise detection. An in-house static image analysis code is developed for acquired thermograms processing.
