초록

본 논문은 경면체의 3차원 형상을 측정하기 위한 광학시스템에 관한 것으로, 특히 LED 배열로 이루어진 점광원과 하프미러,이미지센서로 구성된 비전시스템을 구성하여 광로분석을 수행하고 효과적인 근사화 방법을 제시한다. 실험을 통하여 취득된 영상 내의 점광원의 상대적 위치변화로부터 경면체의 3차원형상의 효과적 추정이 가능함을 보인다.

Abstract

An optical method to measure the three-dimensional (3D) shape of a surface with specular reflection is proposed. The proposedmethod is based on the analysis of the geometric path of the light from a point source, and the relative displacements of pointsin the reflection image. The 3D shape of a concave mirror is shown to be determined approximately via experiments, where thevision system consists of LED array illumination, a half-mirror, and an imaging sensor.
