Abstract
In accordance with one aspect of the disclosure, a driver monitoring apparatus includes: a camera having a field of view facing a driver's seat of a vehicle and configured to provide image data; and a controller configured to process the image data, and the controller is configured to identify at least one of a respiratory rate per minute or a respiratory volume of a driver based on the image data, identify whether the driver is in a state of a drowsy driving based on at least one of the respiratory rate per minute or the respiratory volume of the driver, and provide a control request to output a warning message through a display and speaker of the vehicle based on the drowsy driving of the driver.
Claims16
A driver monitoring apparatus comprising:
- a camera having a field of view facing a driver's seat of a vehicle and configured to provide image data;
- and
- a controller configured to process the image data, and
- wherein the controller is further configured to:
- identify at least one of a respiratory rate per minute or a respiratory volume of a driver based on the image data,
- identify whether the driver is in a state of a drowsy driving based on at least one of the respiratory rate per minute or the respiratory volume of the driver, and
- provide a control request to output a warning message through at least one of a display or a speaker of the vehicle based on the drowsy driving of the driver, and
- wherein the camera comprises:
- a light source;
- a first Schlieren mirror in a shape of a concave mirror that reflects light emitted from the light source toward a front of the driver's seat;
- a second Schlieren mirror in a shape of a concave mirror that reflects light passing through the front of the driver's seat;
- a blocker configured to block a part of the light reflected by the second Schlieren mirror;
- and
- an image sensor configured to receive light that is not blocked by the blocker.
A vehicle comprising:
- a display;
- a seat driving device configured to move a driver's seat;
- a power steering configured to assist a steering of the vehicle;
- a camera having a field of view facing the driver's seat and configured to provide image data;
- and
- a controller configured to process the image data, and
- wherein the controller is further configured to:
- identify at least one of a respiratory rate per minute or a respiratory volume of a driver based on the image data,
- identify whether the driver is in a state of a drowsy driving based on at least one of the respiratory rate per minute or the respiratory volume of the driver, and
- at least one of:
- control the display to output a warning message;
- control the seat driving device to vibrate the driver's seat;
- or control the power steering to vibrate a steering wheel based on the drowsy driving of the driver, and
- wherein the camera comprises:
- a light source;
- a first Schlieren mirror in a shape of a concave mirror that reflects light emitted from the light source toward a front of the driver's seat;
- a second Schlieren mirror in a shape of a concave mirror that reflects light passing through the front of the driver's seat;
- a blocker configured to block a part of the light reflected by the second Schlieren mirror;
- and
- an image sensor configured to receive light that is not blocked by the blocker.
A control method of a vehicle, the control method comprising:
- photographing an image by a Schlieren-type camera having a field of view facing a driver's seat of a vehicle;
- identifying at least one of a respiratory rate per minute or a respiratory volume of a driver based on the image;
- identifying whether the driver is in a state of a drowsy driving based on at least one of the respiratory rate per minute or the respiratory volume of the driver;
- performing at least one of:
- outputting a warning message based on the drowsy driving of the driver;
- vibrating the driver's seat based on the drowsy driving of the driver;
- or vibrating a steering wheel based on the drowsy driving of the driver, and
- wherein the camera comprises:
- a light source;
- a first Schlieren mirror in a shape of a concave mirror that reflects light emitted from the light source toward a front of the driver's seat;
- a second Schlieren mirror in a shape of a concave mirror that reflects light passing through the front of the driver's seat;
- a blocker configured to block a part of the light reflected by the second Schlieren mirror;
- and
- an image sensor configured to receive light that is not blocked by the blocker.
