    摘要: An apparatus (100) for detecting a specular surface in a scene (110) is provided. The apparatus (100) includes an illumination device (120) configured to emit polarized light (130) towards the scene (110). The apparatus (100) further includes an imaging system (140) configured to capture a first image of the scene (110) based on light emanating from the scene (110). The light emanating from the scene includes one or more reflection (132, 134) of the emitted polarized light (130). The imaging system (140) is further configured to capture a second image of the scene (110) based on filtered light (136). The apparatus (100) further includes a polarization filter (150) configured to generate the filtered light (136) by filtering the light emanating from the scene (110). The apparatus (100) further includes processing circuitry (160) configured to determine presence of the specular surface in the scene (110) based on a comparison of the first image and the second image.
