Accessory Structures of the Eye01:17

Accessory Structures of the Eye

4.4K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

    • Human-Computer Interaction

    Background:

    • Driver fatigue is a significant factor contributing to traffic accidents.
    • Developing effective driver fatigue detection systems is crucial for road safety.

    Purpose of the Study:

    • To develop a machine vision-based method for detecting driver fatigue.
    • To utilize the PERCLOS (percentage of eye closure time) parameter for fatigue assessment.

    Main Methods:

    • Implemented a workflow including face and eye detection, tracking, and state recognition.
    • Calculated the PERCLOS value by analyzing eye closure ratio over a defined period.
    • Developed a driver fatigue testing system based on the PERCLOS metric.

    Main Results:

    • The system successfully identified driver fatigue based on a predefined PERCLOS threshold.
    • Alerts were triggered when the driver's eye closure exceeded the set limit.

    Conclusions:

    • The developed system demonstrates rapid computing speed and high accuracy.
    • The system meets real-time requirements for effective driver fatigue detection.
    • Experimental validation confirms the system's efficacy in accord with real-time needs.
