FPGA-based Hardware-in-the-Loop environment using video injection concept for camera-based systems in automotive applications

In this paper an FPGA-based video HiL (Hardwarein-the-Loop) solution is presented. It was designed to evaluate an of-the-shelf ADAS (Advanced Driver Assistance System) smart camera consisting of a video sensor (so-called forward looking camera (FLC)) and video processing unit. It allows to directly capture and store on a PC the video stream from the sensor. Then, the pre-recorded sequences can be directly injected into the video processing unit. Therefore, it is possible to evaluate the vision system in the laboratory under conditions almost identical to those present during real test drives. Moreover, all experiments are fully repeatable. The proposed system supports video streams with resolution 1280×960 @ 30 fps in the RCCC (Red/Clear)1 colour system. It is used in research and development projects in Delphi Technical Center Krakow.
