How It Works
DMS (Driver Monitoring System): an in-cabin infrared camera faces the driver. With a 940nm near-infrared active light source (no red glow, no driver distraction) and a global-shutter sensor, it eliminates motion blur from hand movements and road bumps, and steadily captures eyelid closure, eye-closure duration (PERCLOS), head pose and gaze direction. Algorithms detect fatigue, distraction, phone use and other risky behaviors in real time and trigger alerts.
BSD (Blind Spot Detection): wide-angle rear-side cameras mount on both sides of the tail or the rear bumper, watching vehicles approaching in adjacent lanes and blind-zone targets. Combined with turn-signal status they support blind spot detection (BSD), lane change assist (LCA), rear cross traffic alert (RCTA) and door open warning (DOW). Vision naturally supports target classification and trajectory prediction, and can share channels with surround view — more cost-effective than pure millimeter-wave approaches.
Applications
- Commercial fleet compliance: passenger, freight and ride-hailing fleets add driver monitoring per regulations and connect to government supervision platforms
- Passenger-car safety features: the EU GSR regulation already mandates drowsiness warning, required for vehicles exported to Europe
- Insurance & fleet management: fatigue/distraction event recording with cloud alerts to reduce fleet accident rates
- Passenger-car blind-zone safety: vision BSD replacing or augmenting millimeter-wave radar, supporting 5V/6V surround-view + blind-zone fusion architectures
Solution Advantages
- IR + RGB dual options: one platform supports pure-IR DMS and IR+RGB combined modules
- AA line + Class-1000 cleanroom: controlled IR-filter bonding and optical-axis precision for consistent night imaging
- Algorithm-ready: joint tuning with mainstream DMS/BSD algorithm vendors, or complete algorithm solutions available
- Automotive manufacturing & validation: full validation for -40℃~+105℃ wide temperature, vibration and EMC; 100% imaging test before shipment
