  • Patent number: 9313462
    Abstract: A method for detecting the position of a target object in the environment of a host vehicle. The method may include receiving a first position of the target object as detected by an object position sensor which emits waves and receives the waves that are reflected back by the target object, and receiving an image containing the target object as detected by an image sensor. The method may also include projecting the first position on the image, and refining the first position by computing a second refined position of the target object on the basis of a symmetry search within the image.

  • Patent number: 9123247
    Abstract: A surrounding area monitoring apparatus for vehicle includes an infrared camera mounted on a vehicle for capturing images of surrounding area around the vehicle, a unit for generating and displaying images based on image data captured by the camera, and a controller for calibrating output of the camera with respect to a relation between pixels, based on image data produced by imaging a surface of a shutter that opens and closes an aperture introducing a light to the camera, The controller estimates whether a temperature of the camera is stable, based on an operation state of the vehicle, and determines a possibility that a driver is looking at the unit, based on a behavior of the vehicle. When the temperature of the camera is estimated stable and the possibility that the driver is looking at the unit is determined to be low, the means for calibrating executes the calibration.

  • Patent number: 8922648
    Abstract: A moving image capture device captures a first image at a first location along a motion path and captures a second image at a second location along the motion path. The optic center of the first image and the optic center of the second image are determined and a line intersecting the optic centers of the first image and the second image is determined. An imaging plane perpendicular to the line intersecting the optic centers of the first image and the second image is then determined and used to generate a first rotation-cancelled image and a second rotation-cancelled image. The first image is warped onto the generated imaging plane to create the first rotation-cancelled image and the second image is warped onto the generated imaging plane to generate the second rotation-cancelled image. Translational motion is preserved by the first rotation-cancelled image and the second rotation-cancelled image.

  • Patent number: 8406506
    Abstract: A system and method are disclosed for fast sub-pixel optical flow estimation in a two-dimensional or a three-dimensional space. The system includes a pixel-level optical flow estimation module, a matching score map module, and a sub-pixel optical flow estimation module. The pixel-level optical flow estimation module is configured to estimate pixel-level optical flow for each pixel of an input image using a reference image. The matching score map module is configured to generate a matching score map for each pixel being estimated based on pixel-level optical flow estimation. The sub-pixel optical flow estimation module is configured to select the best pixel-level optical flow from multiple pixel-level optical flow candidates, and use the selected pixel-level optical flow, its four neighboring optical flow vectors and matching scores associated with the pixel-level optical flows to estimate the sub-pixel optical flow for the pixel of the input image.

  • Patent number: 8395659
    Abstract: Systems and methods for identifying moving objects from received images are disclosed. Images are received from a stereo image capture device and from a moving image capture device. Distances from the stereo image capture device to points in a captured image are stored in a stereo distance map and distances from the moving image capture device are determined from pairs of images captured by the moving image capture device and stored in a moving distance map. Stereo disparities are determined from distances in the stereo distance map and motion disparities are determined from distances in the moving distance map. A scale is generated from the stereo disparities and the motion disparities. The scale is applied to the motion disparities and the scaled motion disparities and the stereo disparities are used to identify pixels in an image associated with a moving object.

  • Patent number: 8351653
    Abstract: Distance from a moving image capture device to one or more points is determined. An optical flow is calculated from a first image and a second image captured by the moving image capture device. The horizontal component of the optical flow is used to generate a horizontal distance map including horizontal distances and the vertical component of the optical flow is used to generate a vertical distance map including vertical distances. Horizontal weights are applied to the horizontal distance map to generate a modified horizontal distance map where horizontal distances proximate to a vertical line intersecting a focus of expansion are attenuated. Vertical weights are applied to the vertical distance map to generate a modified vertical distance map where vertical distances proximate to a horizontal line intersecting the focus of expansion are attenuated. The modified vertical distance map and the modified horizontal distance map are then summed.
