    • 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 (3) on/at/in transparent marking carriers (4), in particular having reflectively polished surfaces, the at least one illumination device (2) is arranged at a distance from the optical axis (A) of the camera (1) in such a way that the light reflection (5) generated by the at least one illumination device (2) at the surface of the transparent marking carrier (4) is arranged at least alongside the marking represented in the camera image, preferably outside the detection region of the camera (1). The invention furthermore relates to a method in which, for detecting and/or recognizing markings (3) on/at/in transparent marking carriers (4), in particular having reflectively polished surfaces, a marking is illuminated by at least one illumination device (2) spaced apart from the optical axis (A) of the camera (1) 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 (5) generated by the at least one illumination device (2) at the surface of the transparent marking carrier (4) is arranged at least alongside the marking represented in the camera image, preferably outside the detection region of the camera (1).
    • 本发明涉及用于检测和/或识别标记的装置,特别是用于手动处理的装置,包括用于记录标记的照相机和用于照亮标记的至少一个照明装置,其特征在于,用于检测和/或识别标记( 3)在透明标记载体(4)上的/在/处/特别是具有反射抛光的表面,所述至少一个照明装置(2)以相对于照相机(1)的光轴(A) 在透明标记载体(4)的表面处由至少一个照明装置(2)产生的光反射(5)至少布置在相机图像中表示的标记的旁边,优选地在 相机(1)。 本发明还涉及一种方法,其中,用于在透明标记载体(4)上/之上检测和/或识别标记(3),特别是具有反射抛光的表面,标记由至少一个照明装置( 2)相机(1)的光轴(A)间隔开,使得标记在相机图像中以倒置的方式显现,特别是作为暗背景上的亮标记,并且光反射(5 至少在所述透明标记载体(4)的表面处由所述至少一个照明装置(2)产生的至少一个照明装置至少布置在所述照相机图像中表示的标记的旁边,优选地位于所述照相机(1)的检测区域的外部。
