Polarization information under normal illumination conditions, as stated by Shen et al. (2015), can be affected by ambiguities in polarization-based shape sensing and water particles in the air scattering light, which can create issues with functioning of 3D imaging devices. Coarse depth estimates method and LIDAR technology can help reduce ambiguity and determine object size and distance. This awareness is crucial for understanding the benefits and limitations of 3D imaging devices in modern era.
