How accurate is edge-based AI?

Using a dedicated ADAS camera, typical accuracies are as follows:

• Lane Departure Warning  95%
  
• Forward Collision Warning  95%
• Pedestrian Detection Warning  90%

Factors affecting ADAS accuracy include:

• Placement and calibration of camera
• Sensitivity settings in configuration
• Very high speeds
• Extreme weather
• Poor light conditions
• The need for the preceding vehicle to be in the same 'recognized lane'
• Human-shaped standing signs or roadside dummies (however, portrait patterns on the preceding vehicle or on a roadside billboard rarely trigger)
• Accurate inputs from the Left and Right indicators
• Water stains, cement joints, or other line-like marks on the roadway.

Using a dedicated ADAS camera, typical accuracies are as follows:

• Fatigue                  95%
• Distraction          95%
• Phone                   95%
• Smoking                               95%
• Seat belt                               90%

Factors affecting DSM accuracy include:

• Placement and calibration of camera
• Sensitivity settings in configuration
• Frequently blinking
• Deep sunken eyes or long eyelashes
• Eye glass reflection
• Sunglasses and glasses that block infrared
• Masks, thick beards and other objects around the mouth
• Strong backlighting
• Seatbelt same color and texture as driver’s clothing
• Similar shaped and sized objects to a cigarette, e.g. pens
• Hand and cigarette must be in view at the same time
• Hand must not cover more than 80% of the cigarette
• Cigarette is directly facing the DSM camera (no discernible features)
• Cigarette is held horizontally
• Phone is held side-on to the camera (either vertically or horizontally)
• At least 20% of the phone must be visible
• Phone color same as background
• Similar shaped and sized objects to a phone, e.g. walkie-talkies and e-cigarettes
• Hands free calling not detected

In many of the above cases, the AI system will typically trigger an alarm, preferring not to miss a genuine event even though it may be a false positive.

Please also note that the DSM features on an AI Dashcam are largely dependent on the manufacturer firmware. While dashcams such as the VT3500-AI broadly support all main DSM features, its better detections are in the areas of Phone Use and Seatbelts. All other DSM features are better supported with a dedicated DSM camera.
