Abstract
The invention relates to a device for detecting and/or recognizing markings, in particular for manual handling, comprising a camera for recording a marking and at least one illumination device for illuminating a marking, characterized in that, for detecting and/or recognizing markings () on/at/in transparent marking carriers (), in particular having reflectively polished surfaces, the at least one illumination device () is arranged at a distance from the optical axis (A) of the camera () in such a way that the light reflection () generated by the at least one illumination device () at the surface of the transparent marking carrier () is arranged at least alongside the marking represented in the camera image, preferably outside the detection region of the camera (). The invention furthermore relates to a method in which, for detecting and/or recognizing markings () on/at/in transparent marking carriers (), in particular having reflectively polished surfaces, a marking is illuminated by at least one illumination device () spaced apart from the optical axis (A) of the camera () in such a way that the marking appears in inverted fashion in the camera image, in particular as a bright marking on a dark background, and the light reflection () generated by the at least one illumination device () at the surface of the transparent marking carrier () is arranged at least alongside the marking represented in the camera image, preferably outside the detection region of the camera ().
