目的为建立中国装甲车辆乘员的深度知觉阈限值数据库提供技术支撑。方法在7个自然地域,利用深度知觉测试仪采集565名17~32岁之间的装甲车辆乘员的深度知觉测试数据,对数据进行不同因素下的统计分析,并与国内外相关研究进行对比。结果在一定范围内,变异刺激与标准不变刺激的距离对深度知觉阈限值无显著性影响;双眼与单眼的深度知觉阈限值具有显著性差异;不同学历和生活地区的装甲车辆乘员的深度知觉能力无显著性差异;装甲车辆乘员的深度知觉误差小于普通人群、海员以及驾驶员。结论研究结果能够为初步建立我国装甲车辆乘员的深度知觉数据库提供数据支持,也可为认知参数研究提供参考。
Objective To provide technical support for establishing a database of depth perception threshold for Chinese armored vehicles. Methods Depth perception test data of 565 armored vehicle occupants between 17 and 32 years old were collected by using depth perception tester in seven natural regions. The data were analyzed under different factors and compared with the related studies at home and abroad. Results Within a certain range, there was no significant difference in depth perception threshold between variation stimulus and standard invariant stimulus. There was significant difference between depth perception thresholds of binocular and monocular. For armored vehicle occupants of different academic qualifications and living quarters There was no significant difference in depth perception ability; the depth perception error of armored vehicle occupants was less than that of the general population, seafarers and pilots. Conclusion The results of this study can provide data support for the initial establishment of depth perception database for armored vehicle occupants in China and provide reference for the study of cognitive parameters.
