Design of Fuzzy Inference System for Cameras Inter-Axial Distance Control of Remote Stereoscopic Photographs

ABSTRACT The common way to obtain a stereoscopic image of a subject at a distance is to place two cameras on the parallel axis rather than crossing axis. To find the IAD and maximum focal length, left and right images are obtained by varying the IAD of cameras and the focal length of the camera lens and the depth budget for the obtained images is analyzed through post production. Then, the database for IAD and focal length of the camera lens with the depth range that does not cause visual fatigue and visual discomfort are developed. These data are used to design fuzzy control and deduce the IAD and focal length of the camera lens to shoot a subject at a distance, and the function of the fuzzy control is confirmed through the actual shooting within the range of deduced IAD and focal length of the camera lens. 키워드 : 원거리 입체영상, 수평식 리그, 깊이범위, 깊이 총량, 퍼지추론 Key word : Remote Stereoscopic Photographs, Parallel Rig, IAD, Depth Range, Depth Budget, Fuzzy InferenceJournal of the Korea Institute of Information andCommunication Engineering
