  • Publication number: 20190039518
    Abstract: A vehicular vision system includes a rearward viewing camera and a control, which includes a processor that processes image data captured by the camera. During a reversing maneuver of the vehicle, the control, via processing of captured image data, detects points of interest of detected objects. Responsive to detection of the points of interest of the detected objects, the control determines if the detected objects have height dimensions and determines that objects having a height dimension greater than a threshold height are objects of interest. During the reversing maneuver of the vehicle, the control determines distances to the determined objects of interest and determines which object of interest is closest to the vehicle. During the reversing maneuver of the vehicle, responsive to the determination of the closest object of interest rearward of the vehicle, the control determines whether the determined closest object of interest is a potential hazard.

  • Publication number: 20190001889
    Abstract: A vehicular vision system includes front, rear, driver-side camera and passenger-side cameras each having a respective field of view exterior of the vehicle. Each of the cameras connects with a central video/image processor via a respective mono coaxial cable. Image data captured by the imaging sensor of each camera is carried as captured to the central video/image processor via said the respective mono coaxial cable as a Low Voltage Differential Signal (LVDS). The central video/image processor generates an output provided to a video display device of the vehicle, with the video display device having a video display screen viewable by a driver of the vehicle. The video display screen is operable to display a birds-eye view of an area around the vehicle. The birds-eye view of the area around the vehicle is derived, at least in part, from image data captured by the imaging sensors of the cameras.
