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.A system and method for detecting a camera's position and orientation comprising - at least two transponders arranged in known positions relative to a reference on the camera, - at least two detectors designed to determine the distance from the respective detector to said transponders, - equipment to calculate, in a selected coordinate system, a position of said transponders and a vector representing the direction of a reference axis on the camera based on data from said detectors and communication links between the respective units of the system. From at least two base positions, the distance to the transponders is determined when the base positions are known positions in a selected coordinate system, the position of the transponders in the selected coordinate system is calculated, and from these, a direction vector representing the direction of a reference axis on the camera is calculated.
