Flexible Modeling of High-Definition Matrix Headlights

The contribution at hand presents a novel flexible matrix headlight modeling approach for rapid prototyping that is not based on ray tracing and focuses on parameters which are meant to be intuitive and interpretable. The model parameters are directly linked to the beam pattern of the headlamp. The model is designed to generate illuminations of arbitrary matrix headlights that contain color information and inhomogeneities, making it possible to virtually prototype headlight design concepts in the pre-development phase of the system. The modeling approach is verified by comparing the generated intensity distribution with a real one of low and high resolution systems currently under development. The model has a mean absolute error of about one percent of the maximum intensity for all tested systems.
