US Patent 9769392 Imaging system for addressing specular reflection

The high-intensity specular reflection of light from a surface of an object may create distortions in images of the object, in locations determined based on a perspective of an optical sensor. Multiple images of the object taken from different perspectives may include multiple specular artifacts in different locations, and a composite image of the object that omits such artifacts may be generated based on the multiple images. In particular, pixels of each of the images corresponding to the locations of the specular artifacts and having optimal intensities may be identified. The composite image may be generated based on the pixels having optimal intensities, and by excluding the pixels corresponding to the specular artifacts.
