Attenuation of forest fire engine driver's indirect visual field in virtual fire environment
-
Abstract
Starting with the research on traditional testing of indirect visual fields, this paper establishes a
virtual indirect visual field test system of forest fire engine, gets the attenuation value of forest fire engine
driver's indirect visual field in virtual fire environment. The results showed that indirect visual field
attenuation of forest fire engine driver lead to the accident; C column blind area increased slightly with
forest fire engine driver's indirect visual field attenuation; the indirect visual field attenuate extent of
forest fire engine driver moving forward is less than it reversing; the indirect visual field attenuation is
lower under point stroboscopic light source and the indirect visual field attenuation is larger under mobile
stroboscopic light source; the indirect visual field attenuation with smoke and noise is the most obvious in
same light environment; the indirect visual field attenuation of forest fire engine driver in photopic vision
is not obvious and that in scotopic vision is obvious.
