Three-Dimensional Shape Measurement of a Specular Object by LED Array Reflection

Abstract: An optical method to measure the three-dimensional (3D) shape of a surface with specular reflection is proposed. The proposed method is based on the analysis of the geometric path of the light from a point source, and the relative displacements of points in the reflection image. The 3D shape of a concave mirror is shown to be determined approximately via experiments, where the vision system consists of LED array illumination, a half-mirror, and an imaging sensor. . 나아가서, 간섭무 늬(Fringe)와 같이 특정 패턴과 위상정보를 갖는 구조광을 … Show more
