To satisfy the requirements of road condition assessment an embedded lightfield system, combining 2D texture and 3D geometry, is required. An experimental prototype is proposed. Various approaches for lightfield acquisition were considered. In the end multi-view stereo was identified as the most suitable. Four camera pairs provide the raw data which is preprocessed and transmitted to the main processing unit, where the data is fused into one coherent dataset, via HDMI/DVI. Hybrid Zynq SoC technology was chosen to be able to support sequential and parallel computation paradigms. The system is adaptable to different fields of application due to its modular setup.
