Abstract

We try to extract three-dimensional information, such as the distance from a camera and the actual width and height of an object, from still photographs by a multilens smartphone camera, by means of parallax error. To obtain this information, we develop several formulas and design a method for experimental instrumentation. If the results from this paper were included in algorithms of multilens smartphone cameras, there would be various kinds of applications, such as in the workplace of architectural and civil engineering to obtain an actual dimension, or on a golf course to measure how far away a pin flag is. We expect many more applications of this study, because the multilens smartphone camera is already an important necessity of life.

스마트폰 카메라의 멀티렌즈에서 발생되는 시차현상을 이용하여 실측의 3차원 공간정보를 획득할 수 있는 방법에 대해 연구를 진행하였다. 이를 위한 실험·계측법도 구상해 보았고 관련 방정식도 개발하였다. 본 연구결과를 스마트폰 카메라의 멀티렌즈에 적용하게 되면 건축이나 토목현장에서 스마트폰만으로 한 번에 전체 피사체의 3차원 공간정보를 손쉽게 획득하거나 골프장에서 핀까지의 거리가 얼마나 남았는지 편리하게 알아낼 수 있을 것이다. 멀티렌즈 스마트폰과 연계된 이 기술의 다양한 응용성을 기대해 본다.
