Abstract

This contribution presents a novel algorithm for real-time simulation of adaptive matrix- and pixel-headlights for motor vehicles. The simulation can generate the light distribution of a pair of pixel-headlamps with a resolution of more than one and a half million matrix-elements per light module in real-time. This performance is achieved by dividing the superposition process of the matrix-light-sources into an offline and an online part. The offline part creates a light database that is used by the online component to generate the illumination in memory access efficient way. For an ideal pixel-headlight the run-time of the approach is nearly constant by increasing the number of matrix-lights. This contribution evaluates the visual quality of the simulation. It also presents the changes in the run-time for different pixel-headlamp resolutions and solid angle discretizations.
