Road surface brightness change VR perception simulation method and system considering road type and humidity degree

The invention provides a road surface brightness change VR perception simulation method and system considering road types and moisture degrees, and the method comprises the following steps: constructing a VR observation road model comprising a plurality of different types of road surface regions, and defining optical characteristic parameters for each type of road surface region; adding a plurality of organic light emitting diode (OLED) arrays in the model, wherein each OLED array corresponds to one type of road surface; driver view parameters are defined in the model, an in-view range and an out-of-view range are divided, and a corresponding OLED array is adjusted; selecting one road surface as a reference road surface, and taking the brightness distribution data of the OLED array of the reference road surface as reference brightness distribution; adjusting the brightness distribution of OLED arrays of other pavements according to the reference brightness distribution and the relationship between the referen
