Transcript of Dieter Laskowski Jesse Harvey Mark Cataldi. Outline Overview Analytical Components Testing...
Overview Drowsiness slows reaction time, decreases
awareness, and impairs judgment, just like drugs or alcohol
The driver was apparently drunk and fell asleep when he crashed into the cyclists. One rider was killed and 10 others injured in the incident.
The truck driver was driving fast and he was sleepy; consequently, the truck hit a palm tree then it flipped.
The day-care bus crashed into a bridge killing the driver and four of the six children aboard. The National Transportation Safety Board said the driver fell asleep.
Overview One camera will monitor
the drivers eyes
A second camera will monitor the roadway
If a situation arises the warning system will be activated, alerting the driver
Cameras Product: Logitech QuickCam®
Pro 9000
Retail Price: ~$100
Relevant Features:Premium autofocus: Images stay razor-sharp, even in
close-ups.
Ultra-wide field of view and intelligent face tracking: Keeps you right in the middle of the action.
Modifications:Infrared capabilities
Warning System Controller Alert devices are controlled using
Freescale HCS12 development board.
Software receives alert commands via serial port on laptop and takes appropriate action:Piezo buzzer issued appropriate PWM signal.Massage pad activated using DC signal.
External switch attached to board is capable of inhibiting alert peripherals
Power System Product: Sima STP-325
Retail Price: $30.62
Relevant Features:Low battery alarm
Two short circuit protected AC outlets
Mounting feet for easy and safe installation in any vehicle to vehicles 12v supply
Cigarette lighter plug provided
Alligator clips and cable for installation
Automatic thermal protection indicator
325 Watts Continuous, 650 Watts Peak power
Machine Perception Toolbox Supplies cross-platform libraries for real-
time perception primitives, including face detection, eye detection, blink detection and color tracking.
Our Application: Wrapper around Machine Perception Toolbox (MPT) blink detection to determine if user is becoming drowsy or sleeping.
Testing: MPT Blink Detection
Two team members will drive around together at different times throughout the day to determine how effective the blink detection is under different lighting conditions and real world situations.

Testing: Lane Detection Two team members will drive around together at different times
throughout the day to determine how effective the lane detection is under different lighting conditions and real world situations.
Approximate Time Testing Condition
Sunrise Sun shining directly into camera
10:00 am General observations
12:00 pm Sun overhead, observe effects on road
2:00 pm General observations
Sunset Sun shining directly into camera
Night Observe effectiveness of headlamps with image processing
Sunrise Test image detection when raining under various lighting conditions
10:00 am Test image detection when raining under various lighting conditions
12:00 pm Test image detection when raining under various lighting conditions
2:00 pm Test image detection when raining under various lighting conditions
Sunset Test image detection when raining under various lighting conditions
Night Test image detection when raining under various lighting conditions
Testing: Warning System During testing, the inputs will be forced to create a
warning condition. When the control system detects this, the alarm system should respond promptly.
Each component will be individually checked to verify that it does in fact turn on when commanded.
The warning system will also be thoroughly tested after integration with MPT and Lane Detection
Peripheral inhibit switch will be tested to ensure that no alerts are issued when the switch is activated.
Testing: Power Systems
When all devices are completed, they will be installed into the car and connected to the power inverter.
The system will be tested with maximum strain on the cars power system
Deliverables: Drowsy Driver Warning System set up inside
of a cardboard mock car
LCD monitor set up outside of the car so the audience will be able to see the results of the Blink and Lane detection.
Car driver will simulate falling asleep to force a response from the warning system
The demonstration will wrap up with a question and answer session as well as an opportunity for volunteers to try out the system.
