摘　　要：采用10名乒乓球专业运动员为被试,以乒乓球发球片段为运动情境,结合双眼视差成像原理的偏正光技术在实验室形成立体环境为素材,对专业运动员的视觉搜索特征进行实验研究,同时进行平面视觉和立体视觉条件下运动员视觉搜索特征的比较研究。结果表明:在不同视觉条件下,乒乓球运动员的视觉搜索特征和操作绩效存在差异。在立体视觉成像条件下乒乓球运动员接发球落点的判断反应快,且运动员的采用了注视次数少,视觉搜索频率快,注视分配和注视轨迹更倾向于集中的搜索模式。运动员在立体视觉条件下视觉信息加工效率更高。10 professional players took part in the experiment.It used table tennis serving as sport situation.The stereographic projection technology was used in a three-dimensional environment in laboratory.The authors compared the feature of table tennis players＇visual search between visual condition and stereo vision condition.The result indicated the table tennis players had a significant difference about the visual search strategy and behavior response under the different visual condition.The players＇judgment was faster in the stereo visual condition.The table tennis player used more efficiently search strategy involving less fixation number and lower fixation frequency.Fixation track and Gaze position of the table tennis players were more focused than that of players under visual condition.In the stereo vision condition visual information processing of the table tennis players was more efficiency.
