摘　　要：获取适当位差的立体影像是自由立体显示系统的重要环节。针对该问题,提出了无导轨实景拍摄立体影像的过程和方法。分析并计算了立体包容范围与相机间距的关系,建立了立体场景包容范围模型。在测量自制各尺寸显示器的水平视差极限后,给出了最佳拍摄间距,为立体实景拍摄和制作提供了理论依据。Obtaining stereo images with suitable parallax is an important step in autostereoscopic display system. Aiming at this problem, the process and method of shooting stereo images to actual scene without guide way are proposed. The relationship between stereo tolerance range and distance of cameras is analyzed and calculated, the tolerance range model for three-dimensional scene is established. After measuring the horizontal parallax limit of all sizes of autostereoscopic monitors, the optimal distance of cameras is gained and theory for shooting stereo actual scene is proposed.
