Description

technical field [0001] The present invention relates to a technology in the field of navigation, specifically a visual ADAS (Advanced Driving Assistant System, Advanced Driving Assistant System)-ECU (Electronic Control Unit, Electronic Control Unit) hardware-in-the-loop simulation based on a high-fidelity game engine test system. Background technique [0002] With the rise of related industries such as unmanned driving systems and vehicle intelligence, the testing of vehicle intelligent systems has become a hot issue today. In the field of vehicle intelligence, vision-based ADAS-ECU sensors have covered target recognition, traffic sign recognition, night vision, lane departure, blind spot monitoring, panoramic parking and many other usage scenarios. Due to the need for sensor safety, robustness, and intelligence, there is a wide range of requirements for ADAS controller hardware-in-the-loop simulation testing. [0003] For vehicle-mounted sensors, the stability and robustn...
