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.
