  • Patent number: 8836781
    Abstract: Technology for system and method of providing surrounding information of a vehicle which accurately calculates positions of obstacles around the vehicle is provided. The system includes a plurality of image acquisition units installed in the vehicle at a preset interval, an image acquisition unit selector which selects at least two image acquisition units of the plurality of image acquisition units and receives image data from the selected acquisition unit selector, and a control unit which recognizes an obstacle from the image data received from the image acquisition units, calculates a position of the obstacle, and controls the image acquisition unit selector to select the at least two image acquisition units of the plurality of image acquisition units according to information for vehicle speed of the vehicle.

  • Patent number: 8340368
    Abstract: The present invention relates to a face detection system for a vehicle. At least one first lighting unit is configured to radiate infrared light onto a left side of a driver's face. At least one second lighting unit is configured to radiate infrared light onto a right side of the driver's face. An image capturing unit separately captures the driver's face onto which the infrared light is radiated from the first and second lighting units. A control unit acquires left and right images of the face from the image capturing unit, and obtains a difference image between the acquired left and right images, thus determining whether the driver is inattentive in looking ahead. The system stably performs the face detection function with no or less effect by external optical environments as well as reduced computational load.

  • Publication number: 20080133091
    Abstract: An apparatus for adjusting a position of a side mirror camera of a vehicle includes a light source at the rear of the vehicle, emitting light toward the front of the vehicle. An image processing unit matches an image obtained by the camera with a reference image. A control unit adjusts the position of the camera based on the matching of the images. A method of adjusting a position of a side mirror camera of a vehicle includes: providing a light source at the rear of the vehicle to emit light toward the front of the vehicle, obtaining an image with the camera, matching the image obtained by the camera with a reference image, and adjusting the position of the camera based on the result of the matching. The matching may include binarizing the image obtained by the camera.
