THE GEOMETRICAL MODEL THERMOVISION IMAGE OF RAW MATERIALS'' SURFACE CHARGED INTO THE BLAST FURNACE
Blast furnace usually has charging systems that implement a discharge chute in the throat of the furnace. Whereas thermal imaging camera should be located peripherally at an angle to the vertical. This model takes into account both stationary thermal imaging camera location in the throat of the furnace, objective's field of view and dynamically changing distance from the camera to the surface of charged raw materials, and functionally changing the diameter of the blast furnace shaft.
