Abstract

IMUNIDADE DE METAL EM UM SISTEMA MAGNéTICO INVERSO. A presente ivensão refere-se a um método para rastrear um objeto que inclui a fixação ao objeto em transmissor para transmitir um compo magnético indicativo de posição e prover um mapa de distorção do compo magnético indicativo de posição causado pelo objeto. Um campo magnético distorcido transmitido a partir do objeto é lido. O campo magnético distorcido inclui o campo magnético indicativo de posição sujeito a distorção causada pelo objeto. As coordenadas estimadas do objeto com base no campo magnético distorcido, lido são determinadas. As coordenadas estimadas e o mapa são usados para computar as coordenadas corretas.
