MEASUREMENT OF THE WEAR OF THE FIREPROOF LINING OF A METALLURGICAL VESSEL

摘要

According to the inventive method for identifying and determining the position of a metallurgical vessel for measuring its fireproof lining using electromagnetic 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 ( DOLLAR 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 ( phi (n)), theta (m)) are used to scale the operator. The dimension and resolution of the operator (i:[-imax, imax, DELTA i];: [-jmax, jmax, DELTA i]) in the image co-ordinates system and the anticipated values of the operator (R(m+j,n+j)) are adapted to the measured polar co-ordinates (Rad(m,n), phi (m), theta (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 determined from the position of the minimum result value.
