A study on the relationship between shooting conditions and cardboard effect of stereoscopic images

Simulation of Distortion in Image Space due to Observer's Rotation Movement in Stereoscopic Display, and Its Correction

“…[1][2][3][4][5][6] 이러한 영상왜곡은 관 찰자에게 잘못된 영상정보를 제공한다. 그러므로 스테레오 영상의 왜곡제거는 관찰자에게 올바른 영상정보 획득 및 눈 의 피로를 완화시켜 주기 위해 필요하다.…”

Objective Evaluation Criteria for Stereo Camera Shooting Quality Under Different Shooting Parameters and Shooting Distances

“…Previous proposed stereo shooting principles or models generally take part of influenced factors into consideration or based on human perception, also the shooting principles are two-level evaluation criteria. In 2000, Yamanoue et al based on a five-point scale of subjective perception, studied the relationship between shooting condition and cardboard effect of stereoscopic images [10]. Later, they used the five-point scale as the evaluation level in the subjective experiment in the work [15], and did the geometrical analysis of puppet-theater and cardboard effects.…”

“…To address the above issues, several studies have investigated the effect of shooting conditions on the shooting quality [7], [8] which can be categorized into the subjective [9] and objective assessment methods [10]. Since subjective methods are time-consuming and impractical for online applications, objective methods have attracted more attention.…”

“…Kim et al [16] proposed a visual fatigue metric that could predict the levels of visual fatigue result from stereoscopic images by considering the impact of shooting distance and inter-camera distance. By analyzing the influence of inter-camera distance and camera focal length on cardboard effect, Yamanoue et al [10] introduced parameter setting principles to achieve good stereoscopic image quality.…”

Vergence Control of Binocular Stereoscopic Camera Using Disparity Information

“…Human beings repeat focus control of the thickness of the eye lens, according to the distance, and vergence control, which always keeps the key-object formed in the center of both the retinas and so, provides evernatural and clear image information [1][2][3][4][5]. The multiple cameras with two or more sensors or a lens array composed of many lenses are used to get three-dimensional data [6][7][8].…”
