CAMERA AND METHOD OF CALIBRATING A CAMERA

摘要

A camera comprising a first imaging part for capturing IR image data of a first field of view, said first imaging part comprising IR optics, a second imaging part for capturing visible light data of a second field of view at least partially overlapping the first field of view, said second imaging part comprising visible light optics, a laser pointer for providing a laser dot in the second field of view, and means for adjusting the first and second field of view relative to each other in dependence of the focusing distance of the first or second imaging part. The camera is arranged to determine the distance z between the camera and an object being imaged by means of the distance d, using the stored relationship. The distance z may be used to align the IR image and the visible light image.
