Claim 0:
1. A method for detection of a heating activity in a material, wherein the heating activity is due to self-combustion within the material, the method comprising:
(a) inputting first video data of a monitored field of view, covering the environment of the material, comprising a plurality of image frames containing thermal data;
(b) determining by model fitting, from the thermal data in the plurality of image frames, parameters related to change of temperature within the material over time; and
(c) comparing the parameters determined in (b) related to change of temperature within the material over time with expected parameters for the heating activity due to self-combustion within the material over time, to determine based on a physics-based model representative of underlying heating phenomena within the material whether the parameters determined in (b) related to change of temperature within the material over time indicate that the heating activity are due to self-combustion within the material, then generating a first detection signal related to heating activity in the material, the generation of the first detection signal being based on a determination whether the parameters determined in (b) indicate occurrence of self-combustion within the material.
