Digitization of Matrix-Headlights That Move as in the Real Test Drive

This contribution presents a novel approach to transfer the illumination of a mechanical actuated automotive matrix-headlamp into a virtual environment. The digitization enables Hardware-in-the-Loop-Evaluations of high definition matrix-headlights in the light laboratory at any day time. This contribution explains the necessary modifications of the virtual night drive simulation for correct illumination with the actuated digitized headlight. The modifications depend on whether the camera is connected to the mechanical actuator or is rigid in the test stand. The advantages and disadvantages of each variant and its implementation are explained. The digitization under the influence of the mechanical movement is evaluated with a real matrix-headlight with 84 pixels as a demonstrator. The different camera variants are compared, and recommendations for the best implementation are given.
