The 3D shape and optical characteristic (refractive index and transmissivity) is an important part of the product quality inspection. Furthermore, at the rebuilt of transparent object in the real word, the parameterizations of the object shape, optical characteristics are necessary. The reconstruction of general specular scenes, either refractive or mirror-like, is one of the few remaining open problems...
An optical measuring approach, by which to measure both the three-dimensional (3D) shape and the refractive index of a transparent object, was described. In order to obtain the 3D shape of a transparent object, contact-type sensors have been widely used in conventional approaches. However, the measurement accuracy of contact-type sensors is susceptible to various factors. The proposed measuring approach...
