Driver state sensing system, driver state sensing method, and vehicle including the same
First Claim
Patent Images
1. A driver state sensing system comprising:
- an image photographing unit comprising a channel to photograph images;
a controller that extracts at least two shape points from driver images sensed in the images and compares a motion vector calculated based on an amount of change of the shape points with at least one drowsiness vector stored in advance to determine whether a driver is in a drowsiness state; and
a warning unit to warn when it is determined that the driver is in a drowsiness state.

Abstract
Disclosed are a driver state sensing system, a driver state sensing method, and a vehicle including the same. The driver state sensing system includes an image photographing unit composed of a single channel to photograph images, a controller that extracts at least one shape point from a driver image sensed in the images and compares a motion vector calculated based on the amount of change of the shape point with at least one drowsiness vector stored in advance to determine whether a driver is in a drowsiness state, and a warning unit to warn when it is determined that the driver is in a drowsiness state.

5. A driver state sensing method comprising:
-
photographing images based on a camera sensor; extracting at least two shape points from driver images sensed in the images; calculating a motion vector based on an amount of change of the shape points; comparing the calculated motion vector with at least one drowsiness vector stored in advance to determine whether a driver is in a drowsiness state; and warning when it is determined that the driver is in the drowsiness state. - View Dependent Claims (6, 7, 8)
