Claim:
1. A method of presenting a visible representation of infrared (IR) radiation information onto an observed real world scene based on IR radiation emitted from said observed real world scene, using a thermography arrangement comprising an IR imaging system, a visible light imaging system, and a visible light projecting system, the method comprising: capturing IR radiation information based on detected IR radiation emitted from said observed real world scene according to a first field of view of said IR imaging system; creating a visible representation of said detected IR radiation in the form of an IR image; projecting a visible light pattern onto said observed real world scene according to a second field of view of said visible light projecting system, said second field of view at least partially overlapping said first field of view; capturing a visible light image of said observed real world scene, said scene comprising said projected visible light pattern, according to a third field of view of said visible light imaging system, said third field of view at least partially overlapping the first and/or the second field of view; detecting said projected visible light pattern in said captured visible light image; determining the pixel displacement d determining the pixel displacement d aligning said IR image to the detected IR radiation emitted from said observed real world scene, based on said pixel displacement d and presenting said aligned IR image by projecting it onto said real world scene according to the second field of view in alignment with the detected IR radiation emitted from the observed real world scene.
