現今3D顯示技術已發展的非常迅速，然而僅有少數的3D軟體有支援立體影像播放等功能，再者觀看自製的3D立體模型時往往產生出視覺舒適度不甚理想等情況，讓人無法長期凝視，因此3D立體影像的呈現變成了一門重要的課題。

觀看3D立體影像時往往由使用者自行調整相機方位，而若非立體影像的專家在調整時經常產生視覺不適等情況。故本研究首先探討立體相機的參數調變對於視差分佈的影響，以及著手分析視差分佈中的不同變數與視覺舒適度的相關性，並依照這類相關性去對虛擬相機參數做調變，並且調變完成後需保有視覺舒適度以及刺激的立體感。

研究中採用虛擬相機模擬立體影像，以OpenGL實作立體瀏覽環境，並且探討不同的3D虛擬相機擺設方式、立體相機間距、相機夾角、以及視差分佈等變數所產生的立體影像。最後依照人因實驗方式決定舒適閾值，並依照此閾值完成具有智慧調變機制的立體模型觀賞軟體。

Recently, the development of the stereo display technology progresses fast. However, less three-dimensional software provides quality stereoscopic render. In using this kind of software, users sometimes have discomfort experience when viewing stereoscopic 3D models. So, producing quality stereoscopic 3D technology becomes an important issue.

Usually, user adjusts the camera position by him or herself when viewing stereoscopic models. Amateur will provoke eye fatigue and feel uncomfortable under improper camera parameters. Therefore, we test the effect of different visual stereo camera’s parameters and parallax distributions. We will propose a stereoscopic camera adjustment algorithm for improving visual comfort and preference of stereoscopic images.

In this paper, we carry out a virtual stereoscopic camera system, which has different positions, convergence angles, and parallax distributions, in OpenGL. When users use this system, the vast majority of the parallax will be constrained in the safe range. It is helpful to improve 3D visual comfort and make 3D display popular.
