ABSTRACT:
The invention relates to a camera having optical systems for recording both IR images and visual images and a laser pointer. A method of determining the position of the laser spot in the IR image based on the position of the laser spot in the visual image is proposed. One or more parameters related to the displacement between the visual image and the IR image are used to determine the displacement of the laser spot in the IR image compared to the position detected in the visual image. In cameras providing functions for fusion or blending of IR and visual images, such parameters are determined during calibration to enable alignment of the images captured by the different optical systems. Hence, in such cameras, the displacement parameters are already present.
