Abstract
System og fremgangsmåte for å registrere et kameras posisjon og orientering som omfatter - minst to transpondere anordnet i kjente posisjoner i forhold til en referanse på kameraet, - minst to detektorer utformet for å kunne bestemme avstanden fra den respektive detektoren til de nevnte transponderne, - utstyr for, i et valgt koordinatsystem, å beregne en posisjon for de nevnte transponderne og en vektor som representerer retningen for en referanseakse på kameraet basert på data fra de nevnte detektorene og - kommunikasjonsforbindelser mellom de respektive enheter i systemet. Fra minst to basisposisjoner bestemmes avstanden til transponderne når basisposisjonene er kjente posisjoner i et valgt koordinatsystem, posisjonen for transponderne i det valgte koordinatsystem beregnes, og fra disse beregnes en retningsvektor som representerer retningen til en referanseakse på kameraet.
