Abstract
A method of obtaining an image of buried structures in an object, comprising: providing a camera for imaging visual and infrared-images; providing a bounded light source; partly irradiating said object by said bounded light source; imaging a non-irradiated area of said object by said camera to image said buried structure; and combining said buried structure image with a visual image of said object. Accordingly an image can be obtained while discarding specular reflections of the object. Additionally there is disclosed a method of enhancing imaging of buried structures in an object, comprising: aligning said infrared light source with a visual light source; providing a first edge analysis of said infrared image; providing a second edge analysis of said visual image; comparing said first and second edge analysis; and discarding edges in said infrared image that are also detected in said second image.
