Abstract
A method and system for acquiring images of a target area by acquiring (S1) a first image of the target area with a first image sensor; acquiring (S2) a second image of said target with a second image sensor; and preprocessing the first and second images by 1) performing a spatial 5 transform (S3) at least one of said first and second images in order to compensate for different image acquisition angles, and 2) at least partly removing (S4) undesired reflexes from the first and second images to form first and second reflex reduced images. With the present invention, it is still possible to eliminate or reduce 10 unwanted reflexes, even though the viewing angles of the two frames are different.
