An apparatus and method for determining the three-dimensional surface profile of the charge or burden in a furnace. A pair of infra-red radiation measuring instruments receives infra-red rays from temperature-characterized points on the surface and generates temperature-position signals for the points. Signals generated by a first instrument are paired with the signals generated by the second instrument that correspond to identical temperature-characterized points. The position in space of each temperature-characterized point is determined from the known relative positions of the instruments and the two position components of the paired signals. |
