Three-in-One Vehicle Operator Sensor. Intelligent Transportation Systems

摘要

The Three-in-One Vehicle Operator Sensor envisioned by Northrop Grumman uses non-intrusive eye tracking and image analysis to perform the following functions: (1) drowsy driver recognition, (2) anti-theft protection, and (3) alcohol-impaired driver recognition. The drowsy driver recognition algorithms were successfully developed and tested using data gathered in the Northrop Grumman automobile simulator and using imagery of drowsy drivers obtained from a major domestic automboile manufacturer. The system correctly identified signs of drowsiness in the automobile manufacturer's imagery even though the subject in the video was wearing eyeglasses. An iris verification system developed at Los Alamos National Laboratory has been identified that can be modified to work in the vehicle environment. Northrop Grumman is currently utilizing the expertise available at Los Alamos to examine issues specifically related to the performance of iris verification for anti-theft protection of vehicles. The feasibility of alcohol-impaired driver recognition was demonstrated using Northrop Grumman independent research and development funds.
