Abstract

Termografija je postupak beskontaktnog mjerenja temperature te njezine raspodjele na površini mjerenog tijela korištenjem infracrvenih termalnih kamera. Termalne kamere mjere intenzitet infracrvenog elektromagnetskog zračenja kojeg emitiraju svi objekti. Često se koriste u industriji i u istraživačke svrhe zbog svoje preciznosti i praktičnosti. Cilj ovog rada bio je razvoj alata koji će pružati funkcionalnost mjerenja i analize temperaturnih profila elektroničkih sustava na tiskanim pločicama, koristeći kamere nižeg cjenovnog ranga Adafruit MLX90640. Razvijene su dvije programske skripte, jedna za detekciju objekata, tj. ugrijanih čipova i druga za kontinuirano mjerenje temperatura i grafički prikaz mjerenja. Skripte su pisane u programskom jeziku Python, te je korištena biblioteka za računalni vid OpenCV.

Abstract (english)

Thermography is a non-contact method of measuring temperature and its distribution on the surface of a measured object using infrared thermal cameras. Thermal cameras measure the intensity of infrared electromagnetic radiation emitted by all objects. They are often used in industry and research due to their accuracy and convenience. The aim of this study was to develop tools which provide functionality for measuring and analyzing temperature profiles of electronic systems on printed circuit boards using low-cost Adafruit MLX90640 thermal cameras. Two software scripts were developed, one for object detection, i.e., heated chips, and the other for continuous temperature measurement and graphical representation of the measurements. The scripts were written in the Python programming language and the OpenCV computer vision library was used.
