Title:

METHOD FOR MEASURING VISUAL EFFECT OF NON-COLORED TARGET IN DIFFERENT LIGHT ENVIRONMENTS AND SYSTEM THEREOF

Document Type and Number:

WIPO Patent Application WO/2016/078490

Kind Code:

A1

Abstract:

A method for measuring the visual effect of a non-colored target in different light environments and a system thereof. The measurement method comprises: a) setting a light environment; b) placing an target and performing visual recognition of a driver on the target; c) resetting a light environment, and repeating step b); d) processing visual recognition information data obtained through experiments, and establishing a relationship between the visual recognition time and light environment parameters including a color temperature, a color rendering index, and a brightness parameter; and e) analyzing the visual effect according to the processing result of the visual recognition information data. The system comprises a simulated tunnel middle-segment subsystem, a test subsystem, and a data processing subsystem. By means of the measurement method and the system thereof, the visual effect is analyzed for a visual image of a driver for light environment settings of lighting of a road during night and a tunnel middle-segment, and adequate guidance standards are provided for reasonable and efficient setting of a color temperature, a color rendering index, and an average brightness of a lighting apparatus.
