Full-Field 3D Shape Measurement of Specular Surfaces by Direct Phase to Depth Relationship
This paper presents a new Phase Measuring Deflectometry (PMD) method to measure specular object having discontinuous surfaces. A mathematical model is established to directly relate absolute phase and depth, instead of phase and gradient. Based on the model, a hardware measuring system has been set up, which consists of a beam splitter to change the optical path, and two LCD screens to display ...

متن کاملMultichannel Shape from Shading Techniques for Reconstruction of Specular Surfaces
This paper describes a shape from shading technique for the reconstruction of specular surfaces based on refraction and color illumination or multiple pulsed light sources. The technique is used to retrieve the small-scale shape of waveundulated water surfaces in the laboratory and the field.
متن کاملThree-Dimensional Shape Measurements of Specular Objects Using Phase-Measuring Deflectometry
The fast development in the fields of integrated circuits, photovoltaics, the automobile industry, advanced manufacturing, and astronomy have led to the importance and necessity of quickly and accurately obtaining three-dimensional (3D) shape data of specular surfaces for quality control and function evaluation. Owing to the advantages of a large dynamic range, non-contact operation, full-field...
متن کاملDetermining Shape of Specular Surfaces
A new method for determining the shape of specular surfaces is presented in this paper. Our approach reconstructs the shape of specular surfaces from a relationship between the surrounding environment and the observed images of specular surfaces. A prototype system has been implemented. The experimental results show that the proposed method is effective to the reconstruction of specular objects...
