  • Patent number: 9652853
    Abstract: For reduced processing time involved in an image recognition process, correctors 26a and 26b corrects two source images, acquired by two cameras during the imaging of an object, so that when the two source images are arranged side by side in a lateral direction, the imaged object has the same height in both images. A parallax calculation section 28 calculates, by block matching process, a parallax on the basis of the two corrected source images. A parallax image generation section 30 generates a parallax image on the basis of the parallax calculated by the parallax calculation section 28.

  • Publication number: 20170041591
    Abstract: This vehicle-mounted image recognition device achieves improved performance in flashing light source recognition at low cost and without loss of performance in image recognition applications such as preceding vehicle recognition and white line recognition. At staggered exposure timing, imaging is performed alternately with a first imaging unit and a second imaging unit, which form a pair in a vehicle-mounted camera. A flashing light source is detected from one or both of the first image obtained from the first imaging unit and a second image obtained from the second imaging unit, and the following times, exposure of the first imaging unit and the second imaging unit is matched to when the flashing light source is on. Thereby, flashing light sources are recognized with high accuracy without loss of performance of the image recognition function.
