摘    要:从森林消防车的四维动态视野研究入手,建立森林消防车虚拟视野测试系统。通过驾驶员操作视野设备时的直觉判断,找到森林消防车驾驶员视野在四维动态结构下的衰减数值。结果表明:视野衰减会随着动态的结构而发生衰减;衰减的原因是三维静态测试下没有考虑到时间和环境等因素的影响;现有的森林消防车视野设备在设计和制造上存在问题和缺陷;四维动态结构下的衰减理论研究有助于森林消防车视野设备的设计突破。 

关 键 词:间接视野  直接视野  视野衰减  视野盲点  视野盲区

Abstract:Starting with the research on four-dimensional dynamic visual field,this paper establishes a virtual visual field test system of forest fire engine,makes experiments of the driver’s intuitional judgment during operating visual field equipment,and gets the attenuation value of forest fire engine driver’s visual field under four-dimensional dynamic structure.The results showed that the visual field attenuation occurred with the dynamic structure;the reason for attenuation was that the influence of time and environment was neglected under three-dimensional static test;there were design and manufacturing defects in existing forest fire engine visual field equipment;this research on attenuation under four-dimensional dynamic structure will be helpful to breakthrough design on the equipment of forest fire engine visual field.
Keywords:indirect visual field  direct visual field  visual field attenuation  blind spots  blind area
