Driver gaze detection system

摘要

A method for detecting an eyes-off-the-road condition based on an estimated gaze direction of a driver of a vehicle includes monitoring facial feature points of the driver within image input data captured by an in-vehicle camera device. A location for each of a plurality of eye features for an eyeball of the driver is detected based on the monitored facial features. A head pose of the driver is estimated based on the monitored facial feature points. The gaze direction of the driver is estimated based on the detected location for each of the plurality of eye features and the estimated head pose.

1. Method for detecting an eyes-off-the-road condition based on an estimated gaze direction of a driver of a vehicle, comprising:
monitoring facial feature points of the driver within image input data captured by an in-vehicle camera device; detecting a location for each of a plurality of eye features for an eyeball of the driver based on the monitored facial feature points, comprising;
detecting a location of an iris;detecting a location for a first eye corner indicative of an inner eye corner proximate to a nose bridge;detecting a location for a second eye corner indicative of an outer eye corner;for each corresponding eye feature of the plurality of eye features, training a classifier, comprising:
assigning image patches around a reference eye feature respective to the corresponding eye feature obtained from a database; andidentifying one or more of the assigned image patches that are centered around the reference eye feature; estimating a head pose of the driver based on the monitored facial feature points; and estimating the gaze direction of the driver based on the detected location information for each of the plurality of eye features and the estimated head pose.
