The paper presents a multi-angle phase triangulation method for measuring the three-dimensional geometry of convex and extended objects. The method is based on the use of two photodetectors and a light source. Measurements are performed based on the analysis of a stereo pair images obtained from photodetectors. Structured illumination is used as the analyzed texture. The proposed method improves the accuracy of measurements and makes it possible to measure the full three-dimensional geometry of convex and extended objects in an optical manner based on the triangulation principle and structured lighting.
