Method for automatically detecting, by means of computerized processing, of thermal information about a surface of a brake disc under dynamic operating conditions

A method for automatically detecting, by means of computerized processing, information about temperature evolution and/or about location/distribution of hot spots and/or bands and/or zones on the surface of a brake disc under dynamic operating conditions, comprising:

• acquiring a plurality of digital images and/or a digital video, comprising a plurality of digital frames, of at least one zone of interest of the brake disc to be thermally characterized, by means of at least one thermal imaging camera, wherein each of said digital images and/or each of said digital video frames depicts the temperatures detected at each point by means of a color map, wherein said acquiring step is performed during the evolution of said dynamic operating conditions;
• obtaining a representation of each of the digital images and/or digital video frames in the form of matrix data;
• processing said plurality of digital images or plurality of digital video frames, by means of algorithms comprising image analysis or computer vision algorithms, to obtain information about temperature evolution and/or about location/distribution of hot spots and/or bands and/or zones on the zone of interest of the surface of a brake disc;
• providing said obtained information in the form of digital images or graphics and/or digital tables and/or digital video;
• wherein said processing step comprises:
• identifying the zone of interest by generating a mask based on an analysis of the plurality of acquired digital images and/or digital video frames;
• applying the generated mask to each of the digital images and/or digital video frames acquired and obtaining processed matrix data related to the zone of interest;
• defining the area of analysis;
• performing a thermal analysis on the data related to the defined area of analysis to obtain information about the temperature evolution at each point of interest;
• identifying hot spots based on said information about the temperature evolution at each point of interest.
