由于生理的局限，人眼立体感知存在一定的盲区，并对立体视差存在一定的融合极限，因此获取符合人眼立体感知的三维影像就显得尤为重要。针对该问题，结合Panum融合区理论以及人眼立体感知误差，对立体观影区间的范围进行界定，并对立体观影区对应下的基线长度范围进行推导。根据推导结果，利用3ds max进行场景模拟，分别以特定距离下基线长度所允许的最大值和最小值为基准，获取5组不同基线长度下的视差图，最后利用虚拟现实眼镜验证了推导结果的正确性，该结果可对立体摄影过程的相机摆放提供指导。

Because of physiology limitation, there are certain blind spots in the stereo perception of human eyes, and there is a certain fusion limit for the stereoscopic disparity, so it is very important to get the three-dimensional images. To solve this problem, in this paper, the range of stereoscopic view was defined by combining Panum fusion region theory with human eye stereo perception error, and the range of baseline length corresponding to stereoscopic viewing area was deduced. Based on the results, the scene simulation was performed using 3ds max, and five groups of disparity maps at different baseline lengths were obtained based on the maximum and minimum values of the baseline length at specific distances. Finally, the virtual reality glasses were used to verify the results. The results can provide guidance on the placement of the camera in the stereo photography process.
