Small-target light source generating and simulating system

Abstract

The invention discloses a small-target light source generating and simulating system, which comprises a light source and a small target generating assembly for reflecting light emitted from the light source to generate a small target; the small-target light source generating and simulating system also comprises a light guiding assembly which is arranged between the light source and the small target generating assembly and is used for guiding the light emitted from the light source to the small target generating assembly. The small-target light source generating and simulating system is convenient in operation, is high in precision and can perform quantitative control on the random occurrence condition of the small target, data collecting for the small target becomes convenient and feasible while the channel lighting design is facilitated and massive human eye reaction data, under different states, for the small target are obtained; massive effective data can be obtained in the range of cost controlling, test expenditure is reduced, energy consumption in the test process can be effectively saved by resolving, machining and improving a background light source, and the small-target light source generating and simulating system accords with the current concepts of energy saving and environment friendliness.

Description

Technical field [0001] The invention relates to the field of road lighting quality testing for highways and highway tunnels, in particular to a simulation system for generating small targets for light sources. Background technique [0002] With the development of economy and technology, the number of highways and highway tunnels has increased year by year, and the impact of their lighting quality on driving comfort and traffic safety has become increasingly prominent; therefore, a reasonable scale model of the on-site lighting environment was constructed to evaluate the lighting quality of highways and highway tunnels. Evaluation becomes more and more important. There are three brightness levels in highways and highway tunnels: photopic vision, scotopic vision and mesovision, among which the middle vision brightness accounts for the highest proportion; especially for night roads, long tunnels and extra-long tunnels, the middle vision brightness level accounts for about 80% or mor...

AI Technical Summary

Problems solved by technology

[0004] At present, most intermediate vision test devices do not focus on the small target generation system, and only carry out simple construction instead of effective and complete design; or they can only generate fixed eccentricity, but cannot achieve the effect of randomly generating targets; or use independent The light source generates the target, resulting in different spectral distributions between the brightness of the target and the background brightness; or using a fixed distance between the observer and the target, which cannot simulate the scene where the observer approaches the target from far to near

Obviously, the existing small target generation system has not been fully considered, cannot obtain continuous data and is cumbersome to operate, which is not conducive to the smooth progress of the test, and cannot completely simulate the appearance of targets under driving conditions
