Optical Fatigue Detection System

Innovative optical driver fatigue detection system based on machine vision and artificial intelligence


Purpose
Reduces risk for drivers, surrounding people and other road users
Reduces the cost of mitigating the damage caused by accidents
Can be mounted to any automobile or heavy equipment
Generates analytical data for decision-making
Reduces accident rate and risk of damage to machinery and facilities
Increases the safety of operations

The OKO optical fatigue detection system is designed to prevent accidents and emergencies caused by human factors, primarily by driver and heavy equipment operator drowsiness and loss of concentration.

The system is designed for:

  • drivers of cargo and passenger transport, taxis;
  • heavy equipment operators;
  • air traffic controllers;
  • security guards;
  • employees in other safety-related positions, whose activities are characterized by monotony and increased level of fatigue.

Areas of Application
Public and taxi transport

Monitoring of attention and concentration of drivers for safe road traffic
Passenger and cargo transportation
Real-time monitoring of drivers to ensure the safety of passengers and cargo
Mining

Proven, effective detection of driver and operator fatigue for safe mining operations
Industrial and infrastructure facilities
Supporting processes and security services at high-importance facilities
How it works

1) The optical sensors monitor the driver’s eye and pupil movement and head position

2) The machine vision algorithm analyzes the video feed in real-time

3) When an anomaly is registered, an alarm sound is played. If the driver does not restore his attention on the road, a second louder alert is activated

4) The system sends the info about the anomaly to the dispatching center (if deployed)


System Composition

The OKO system is based on the non-contact technology of continuous tracking and recognition of the driver’s eye and head movements.

The combination of equipment capabilities and complex algorithms has enabled a significant increase in the accuracy of the system, almost completely eliminated false alarms, and ensured ease of operation.
1. Optical sensors
The "eyes" of OKO are installed in front of the driver in a non-interfering way to monitor his eyes and face in real-time. The sensors gather data in visual and IR spectrums in a wide cone.

Fun fact: "oko" is Old Russian for "eye", and it was the basis for the name.
2. Central Unit
The central unit serves as the brain of the system. It analyzes the video feed using algotrithms tailored to detect fatigue, drowsiness and distracted attention. When an anomaly is registered, the system activates an alert. If the driver does not restore the attention soon, a second, louder alarm is played.

The unit is equipped with a powerful dual-core microprocessor. The block is integrated into the power grid of the vehicle and has the potential to support more functions and additional types of sensors.
3. Loudspeaker
The loudspeaker activates the alarms when a distraction is detected.
4. Cables
Cords necessary to install the system.
5. Fasteners
The fasteners are used to mount the sensors in the cabin in a comfortable position for the driver.
6. Calibration Button
The only active button in the system is used to initiate the calibration process and to manually turn off the loud alarm if triggered: the first alert is cancelled if the attention is restored, but to turn of the louder one the driver need to consciously press the button.
7. Power Cable
If necessary. the OKO can be connected to the cigarette lighter receptacle. It is usually not recommended convenience-wise, and is frequently used to test the system without connecting it to the vehicle power grid.
8. Antenna
The antenna is used to connect the OKO to the cellphone network and satellite navigation systems (GPS/GLONASS) and to remote-control the unit from the dispatching center.
9. Dispatcher's Account
The dispatcher’s account is used by the designated employee to monitor all the mounted OKO systems in real-time. Also here the dispatcher can export the statistical data accumulated by each individual OKO unit.
Dispatching Platform
The dispatching platform is used to remote control, maintenance and calibrations of the connected OKO units. It also provides the client with the means to gather and visualize the statistical data about the system’s performance.

Dispatching Capabilities
The system is able to function autonomously, without using the dispatching feature. At the same time, the dispatching service increases the usefulness of the system by providing greater management and analysis capabilities.
Control
Real-time monitoring of all drivers simultaneously

Safety
Ability to make informed decisions about pauses in work

Response
Visualization of current levels of fatigue on the basis of increased frequency of triggers

Analysis
Collection of objective data regarding labor productivity to make organizational changes and personnel decisions
