Dynamic Glare Evaluation Along a Route

Abstract

Road lighting measurements are performed capturing low luminances and high luminances in the same image. It is known as High Dynamic Range (HDR) imagery and the technique used here is based on four synchronous CMOS cameras, each dedicated to one luminance range. After geometric and photometric calibration, an image processing algorithm constructs the final 20-bit HDR image. Then threshold increment and visual adaption models are computed to evaluate glare dynamically along a route. For each model, we discuss about the different parameters and their validity in moving situation.
