Abstract

First, if we want to design and construct a robotic camera, we need to understand the parallax errors between adjacent images, caused by rotation and movement of the robotic camera system. In this paper, we try to derive the mathematical formulation of parallax error and connect it to a conventional lens system, to obtain a useful, generalized, analytic algebraic expression for the parallax error. Utilizing this expression, we can structurally design a robotic camera, and study the Google ART camera as an example of a robotic camera.

로봇 카메라를 이해하고 제작하기 위해서는 로봇 카메라의 회전이나 공간 이동에 의해 발생하는 인접 이미지 간의 영상 왜곡에 대한 이해가 우선적으로 진행되어야 한다. 본 논문에서는 영상 왜곡에 관한 수학적인 해석과 이 수학적인 해석을 렌즈 시스템과 연결하여 일반화하고 결국 로봇 카메라에서 일어나는 영상의 왜곡인 parallax 오차에 대한 유용한 해석 방정식을 얻었다. 이 방정식으로부터 로봇 카메라의 구조설계가 가능하게 되고 한 예로서 기존 구글의 ART 로봇 카메라에 대한 분석과 이해가 확장될 수 있었다.
