目的 :建立视觉超分辨能力和几何图形错觉的定量检查方法 ,了解它们在飞行人员中的分布特点 ,研究它们之间的相关性 ,为进一步研究视性飞行错觉提供实验依据。方法 :用计算机编程建立了六种视觉超分辨能力 (游标错开、有干扰的游标错开、弯曲、平分、横向倾斜、竖向倾斜 )和六种几何图形错觉 (Ponzo面积错觉、Ponzo错觉、Ebbinghaus错觉、Mueller -Lyer错觉、水平 -垂直错觉、Poggendorf错觉 )的定量检查方法。对 82名视力正常的飞行人员进行了检查 ,并分析了它们的相关性。结果 :①视觉超分辨能力可分为两类 ,一类的视觉超分辨阈值小于 2 0弧秒 ,像游标错开、有干扰的游标错开、弯曲、平分、它们在检查中均有参考目标紧相邻。另一类的视觉超分辨阈值大于 34弧秒 ,如横向倾斜和竖向倾斜这两种形式 ,它们在检查中没有紧相邻的参考目标。②几何图形错觉也可分为两类 ,一类是错觉量较小 ,均值在 16～ 34弧秒之间 ,如Ponzo面积错觉、Ponzo错觉、Ebbinghaus错觉及Mueller-Lyer错觉 ,它们均有诱导因素存在。另一类是错觉量均值大于 6 0弧秒的 ,如水平 -垂直错觉、Poggendorf错觉 ,它们均无诱导因素。③从相关性分析中可看出每种视觉超分辨能力都与一种以上几何图形错觉相关显著。结论 :成功建立了多种视觉超分
OBJECTIVE: To establish a quantitative inspection method of visual super-resolution and geometrical illusion, understand their distribution characteristics among pilots, study the correlation between them, and provide experimental evidence for further study of visual illusion. Methods: Six kinds of visual super-resolution (cursor misalignment, interfering cursor misalignment, bending, bisecting, lateral tilting, vertical tilting) and six geometrical illusions (Ponzo area illusion, Ponzo illusion, Ebbinghaus illusion , Mueller-Lyer delusion, horizontal-vertical delusion, Poggendorf delusion). 82 normal vision pilots were examined, and analyzed their relevance. Results: (1) The visual super-resolving power can be divided into two categories. One type of visual super-resolution threshold is less than 20 arc seconds. As the cursor is staggered, the interfered cursor is staggered, curved and bisect. adjacent. Another type of visual super-resolution threshold of more than 34 arc seconds, such as horizontal tilt and vertical tilt of these two forms, they do not check in the immediate reference target. (2) Geometric illusion can be divided into two types. One is the small amount of illusion with mean value of 16 ~ 34 arc seconds, such as Ponzo area illusion, Ponzo illusion, Ebbinghaus illusion and Mueller-Lye illusion, exist. The other is that the mean value of illusion is greater than 60 arc seconds, such as horizontal-vertical illusion, Poggendorf illusion, and they have no inducing factor. ③ It can be seen from the correlation analysis that each visual super-resolution ability is significantly related to the illusion of more than one geometry. Conclusion: A variety of visual superextensions have been successfully established
