Abstract

The characteristic temperatures of materials as softening temperature, melting temperature, etc. are defined by national or international norms. These norms give visual description of the special samples of the material at characteristic temperatures. This description is verbal, qualitative, inaccurate in mathematical sense. In the paper a system with furnace and video camera coupled with computer, developed in The Industrial Institute of Electronic in Warsaw, is presented. Fuzzy logic and approximate reasoning methods are used to denote these temperatures, basing on the series of images supplied by video camera.
