Abstract
The invention enables assessment and monitoring of attentiveness of a driver of a vehicle. The invention provides systems, methods and computer program products that determine a driver specific baseline degree of eye openness for a vehicle driver, and thereafter monitor and determine driver attentiveness or alertness based on the determined driver specific baseline degree of eye openness.
Claims19
A method for monitoring a degree of attentiveness for a driver of a vehicle, the method comprising:
- detecting a predefined vehicle operation event;
- responsive to detecting the predefined vehicle operation event, initiating a session specific driver enrolment process for the driver, comprising:
- acquiring at least one baseline eye image of the driver;
- determining baseline eye openness of the driver based on image information within the at least one baseline eye image;
- prior to detection of a predefined session termination event:
- acquiring a set of images of the driver;
- determining real time eye openness of the driver based on image information within the acquired set of images;
- determining a difference value representing a difference between the real time eye openness of the driver and the baseline eye openness of the driver;
- and
- generating a data signal triggering a state change in response to determining that the difference value is greater than a threshold value.
A method for monitoring a degree of attentiveness for a driver of a vehicle, the method comprising:
- detecting a predefined vehicle operation event;
- responsive to detecting the predefined vehicle operation event, initiate a session specific driver enrolment process for the driver, comprising:
- acquiring at least one baseline image of the driver, and responding to determining that the at least one baseline image complies with a set of predefined requirements by:
- determining baseline eye openness of the driver based on the eye image information within the at least one baseline image;
- determining a difference value representing a difference between the baseline eye openness of the driver and a threshold value for eye openness of the driver;
- and
- selecting between a first driver monitoring mode and a second driver monitoring mode, wherein the selection is based on the difference value;
- wherein in the first driver monitoring mode, driver alertness is determined based on image characteristics corresponding to the driver's eye;
- and
- in the second driver monitoring mode, driver alertness is determined based on one or more detected non-eye related characteristics of the driver.
A system for monitoring a degree of attentiveness for a driver of a vehicle, the system comprising:
- a memory;
- and
- a processor configured for:
- detecting a predefined vehicle operation event;
- responsive to detecting the predefined vehicle operation event, initiating a session specific driver enrolment process for the driver, comprising:
- acquiring at least one baseline eye image of the driver;
- determining baseline eye openness of the driver based on image information within the at least one baseline eye image;
- prior to detection of a predefined session termination event:
- acquiring a set of images of the driver;
- determining real time eye openness of the driver based on image information within the acquired set of images;
- determining a difference value representing a difference between the real time eye openness of the driver and the baseline eye openness of the driver;
- and
- generating a data signal triggering a state change in response to determining that the difference value is greater than a threshold value.
