ADAS HIL (Hardware-in-the-Loop) video injection is a test method for advanced driver assistance systems. It takes video data collected from real roads or generated by simulation and sends it directly into the video input interface of the ADAS controller through a video injection device, simulating real-time camera images. In a lab environment, it can reproduce various complex, extreme, or dangerous driving scenarios, enabling closed-loop verification of perception, fusion, decision-making algorithms, and more. Compared to real‑vehicle road testing, video injection offers advantages such as high repeatability, high efficiency, low cost, and no safety risks. It is a key method for ADAS
