摘要 针对3D影片中出现的背景视差过大是否会引起人体不适的问题,我们分析了20名志愿者先后观看明显含有背景视差过大的3D片段和不含背景视差过大的3D片段后P300峰值和潜伏期的变化。发现志愿者在观看含有背景视差过大的3D片段后P300的峰值略高于观看相应不含该问题的3D片段P300的峰值,然而,观看含有背景视差过大的3D片段后P300的潜伏期略低于观看相应不含背景视差过大的P300的潜伏期。结合志愿者的主观评价,可以得出短时间内出现的背景视差过大不会导致人体不适。 In order to explore whether the excessive background parallax (EBP)can lead to human discomfort,20 volunteers par-ticipated in this P300 ERP (Event -Related Potential)experiment.They were asked to watch the 3D segment with EBP firstly and then watch the segment without EBP.The result showed that P300 amplitude that people watched the 3D segment with EBP was a little higher than the 3D segment without EBP.However,there was no change in delay time.Combined with the subjective evaluation of 20 volunteers,it can be concluded that the short -time EBP can not lead to the human discomfort.
