监视员视野的描述和测量

[中文适用范围]： 本 SAE 推荐实践建立了描述和测量驾驶员视野的方法。该文件描述了三种测量直接和间接视野以及这些视野内障碍物范围的方法。第一种方法使用任何单对眼点来确定单个驾驶员可以看到的区域或障碍物。第二种方法使用 SAE J 941 中定义的 SAE 眼椭圆来确定给定百分比的驾驶人群中会看到的最大视野或障碍物。第三种方法使用 SAE J 941 中定义的特定眼点来测量这些点所针对的特定视野或障碍物的范围。 [外文原描述]： This SAE Recommended Practice establishes methods for describing and measuring the driver’s field of view. The document describes three methods for measuring the direct and indirect fields of view and the extent of obstructions within those fields. The first method uses any single pair of eye points to determine the fields or obstructions that would be seen by an individual driver. The second method uses the SAE Eyellipses defined in SAE J941 to determine the largest fields or obstructions that would be seen for a given percentage of the driving population. The third method uses specific eye points defined in SAE J941 to measure the extent of a specific field of view or obstruction for which those points were developed.Cross Reference: J941,J985_201611
