TSR (Traffic Sign Recognition), as a core functional module of ADAS (Advanced Driver Assistance Systems), primarily aims to detect and recognize traffic signs on the road (such as speed limits, no overtaking, parking, etc.) in real time through on-board cameras or sensors, and provide the information to the driver in visual or auditory form, thereby enhancing driving safety and regulatory compliance. Technically, TSR relies on high dynamic range cameras and image processing algorithms, enabling accurate sign recognition under varying lighting and weather conditions, and integrates with navigation systems or Adaptive Cruise Control (ACC) to automatically adjust vehicle speed according to speed limit requirements. The TSR systems in current mainstream vehicle models can already recognize various complex signs, including dynamic electronic signs, with a false alarm rate maintained below 0.1%, while complying with international safety standards such as UN-R152. As autonomous driving technology advances, TSR will be further integrated with systems like lane keeping and path planning, thereby minimizing the risk of human operational errors.
