According to the inventive method for identifying and determining the positi on of a metallurgical vessel for measuring its fireproof lining using electromagneti c radiation, an operator is defined in relation to a two or three dimensional structure with a known shape and size. Distance values (Rad(m,n)) and corresponding measuring angles ($G(f)(n)), .theta.(m)) are determined in the area of the structure and the measured distance value (Rad(m,n)) and corresponding measuring angles (~(n)), .theta.(m)) are used to scale the operator. The dimension and resolution of the operator (i:[-imax, imax, ~i];: [-jmax, jmax, ~i]) in the image co-ordinates system and the anticipated values of the operator (R(m+j,n+j)) are adapted t o the measured polar co-ordinates (Rad(m,n), ~(m), ~(n)). A result value (S(m,n)) is then formed from the differences between the anticipated values of the operator (R(m+i,n+j)) and the measured values (Rad(m+i,n+j)) and the location of the structure that is sought is determine d from the position of the minimum result value.
