随机点立体图在立体视觉测量中的实证效度分析

An Analysis of Empirical Validity on Random-dot Stereogram in Stereo Vision Measurement

立体视觉是人们在观察事物过程中的一种立体知觉,又称深度知觉。在对立体视觉的敏锐度要求较高的职业中,立体视觉的好与坏会直接影响工作质量,甚至对于某些行业来说,会直接威胁到从业者的人身安全。因此,选取一种有效简捷的方法来判断从业人员的立体视觉,对立体视觉的应用有着重要的实践意义。研究目的:以测量立体视觉的传统方法三杆法为校标,检验随机点立体图的实证效度。方法:测量43名大学生的立体视觉,使用斯皮尔曼等级相关与皮尔逊相关检验随机点立体图法的校标关联效度。结果:三杆法与随机点立体图法的测量结果存在显著相关。结论:随机点立体图能有效地测量立体视觉。

Stereo vision is a three-dimensional perception of the people in the process of observing things, also known as depth perception. In occupations requiring a higher three-dimensional visual acuity, good or bad stereoscopic vision will directly affect the quality of work, and even, will directly threaten the personal safety of the practitioners for some industries. Therefore, selecting an effective and simple method to de- termine the three-dimensional vision of the employees has important practical significance for the applica- tion of stereo vision. Objective： Using the traditional three-pin method as a criterion to measure stereo vi- sion, to test the empirical validity of random-dot stereogram. Methods. measuring 43 students~ stereo vi- sion and using the Spearman rank correlation and Pearson correlation to test the criterion-related validity of random-dot stereogram. Results： the results of three-pin method and random-dot stereogram method were significantly related. Conclusion： The random-dot stereogram can effectively measure the Stereo vision.
