  • Patent number: 10315570
    Abstract: An image processing apparatus extracts, as a display image, a part of an image captured by a wide angle camera, the wide angle camera being arranged at a position deviated from a vehicle center line that is a center line of a vehicle in a longitudinal direction and being configured to increase a degree of size reduction of an object as being farther from a center of the captured image. The image processing apparatus includes a control circuit that extracts the display image. The control circuit includes an extraction determination portion. The extraction determination portion determines an extraction position of the display image in the captured image according to a center position of the display image to the vehicle center line and the degree of size reduction of the object represented at a pixel of a specific position in the display image.

  • Patent number: 10235772
    Abstract: An installation error detection apparatus of an onboard camera includes: an input portion that receives a photographed image; a storage portion that stores position information of a feature point of the vehicle; a feature point detection portion; a determination portion that determines whether the installation position of the onboard camera is the proper position; and a notification portion that informs installation defect of the onboard camera. The notification portion calculates the installation position of the onboard camera required to minimize the deviation amount and corrects the photographed image by the onboard camera. The notification portion detects the feature point and calculates a similarity degree of the position of the feature point and the position information. The notification portion determines the installation defect of the onboard camera and informs the installation defect. The notification portion determines that a vehicle body is deformed and informs the vehicle body being deformed.

  • Publication number: 20180350108
    Abstract: A system for determining an estimated backup path or forward path of a trailer hitched to a vehicle. The system includes two cameras for identifying hitch angle without reliance on a predetermined target having a known shape or known dimensions, such as by using automatic camera calibration. The system determines trailer width and trailer tip location without relying on stored trailer parameters.

  • Patent number: 9967526
    Abstract: An image processing device includes an image input section inputting images taken by a vehicle camera, a calibration target specifying section specifying a calibration target included both in a first image and in a second image, a vehicle information input section inputting information indicating travel distance and orientation change of the vehicle, a calculation section, and a storing control section. The calculation section converts the first and the second images to the first and second bird's-eye view images, respectively, arranges the first and the second birds-eye view images on common coordinate system with consideration of corresponding image taking positions and image taking orientations, and calculates at least one orientation parameter of the camera which minimizes position difference and rotation angle difference between the two calibration targets included in the first and second birds-eye view images. The storing control section stores the orientation parameter in storage.

  • Publication number: 20150319370
    Abstract: An onboard image generator is provided. The onboard image generator includes a first camera capturing an image in front of or behind a vehicle, and a second camera and a third camera capturing images on right and left sides of the vehicle, respectively. Based on the images captured by the second and third cameras, a first viewpoint converter generates a set of symmetrical viewpoint conversion images shaped viewed toward the front or rear of the vehicle from a pair of parallel virtual viewpoints. Based on the image captured by the first camera, a center image generator generates a center image. A combined image generator generates a combined image by arranging the center image in a center of and arranging the set of viewpoint conversion images besides the center image.

  • Patent number: 8670034
    Abstract: An image processor outputs an image containing relatively much information of a central area in the horizontal direction. A mask composed of an upper mask and a lower mask is superimposed on the image. The upper mask is concave on the lower side thereof and disposed along the upper side of the image. The lower mask is concave on the upper side thereof and disposed along the lower side of the image. When the image is masked with this mask, the peripheral portion of the image that is prone to be distorted becomes invisible. Therefore, discomfort a user feels because of distortion can be reduced. In addition, the user can view the image with the much information of the central area of the image in the horizontal direction.

  • Publication number: 20110106380
    Abstract: A vehicle surrounding monitoring device includes an image display control section and a guide line overlapping section. The image display control section makes a view image based on a shot image of a surrounding of a vehicle and displays the view image on a display device. The guide line overlapping section overlaps a guide line for assisting a forward parking of the vehicle on the view image. The guide line includes a front end guide line extending from a first position to a second position. The first position is a position obtained by rotationally transferring a position of a rotational outer front end of the vehicle by 90 degrees around a rotational center of the vehicle. The second position is located at a distance of a width of the vehicle from the first position toward a rear in a front-rear direction of the vehicle.
