Abstract: The research presented in this study primarily proposes a simple but efficient method for the generation of depth maps for a certain class of industrial parts. The suggested technique is based on physical principle that the light is absorbed in a color liquid as it travels along an optical path. Consequently the grey level image of an object immersed in a color liquid contains information about the optical path of rays reflected from the object. In other words, the intensity of the grey level image of the object produced in this way is modulated by the depth of the object.!17
