Abstract: A method for stitching image data captured by multiple vehicular cameras includes equipping a vehicle with a vehicular vision system having a control and a plurality of cameras disposed at the vehicle so as to have respective fields of view exterior the vehicle. Image data captured by first and second cameras of the plurality of cameras is processed to detect and track an object present in and moving within an overlapping portion of the fields of view of the first and second cameras. Image data captured by the first and second cameras is stitched, via processing provided captured image data, to form stitched images. Stitching of captured image data is adjusted responsive to determination of a difference between a feature of a detected and tracked object as captured by the first camera and the feature of the detected and tracked object as captured by the second camera.

Abstract: A method of synchronizing cameras with an electronic control unit (ECU) of a vehicular vision system includes providing camera control signals to the cameras from the ECU via respective links from the ECU to the cameras, with the camera control signals regulating timing of the respective camera to be synchronous with reference timing of the ECU. The timing regulation of the cameras includes starting the camera synchronous to the ECU reference timing and holding the camera synchronous to the ECU reference timing. Image data is captured with each camera and provided to the ECU via the respective link. Image data captured by at least one of the cameras may be processed to detect an object present exterior of the vehicle.

Abstract: A vehicle door control system includes a camera disposed at a portion of the vehicle and having a field of view that encompasses a region exterior of the vehicle that is swept by a door of the vehicle as the door is opened and closed via a powered door opening/closing system of the vehicle. An image processor is operable to process image data captured by the camera to detect an object present in the region that is swept by the door when the door is opening and to determine if the door may collide with the detected object when the door is being opened. During opening of the door and responsive to determination of a potential collision of the opening door with the detected object, the vehicle door control system positions the door at a partially open position whereby a gap is established between the door and the detected object.

Abstract: A vehicular vision system includes an image sensor operable to capture image data and an image processor operable to process frames of captured image data. The image processor is operable to detect edges or corners in the captured images. The image processor is operable to determine a number of edges detected in individual frames of captured image data. The vision system adjusts a sensitivity of the image processor responsive to the determined number of edges detected in at least one frame of captured image data. The image processor may detect up to a selected maximum number of edges in a frame of captured image data, and the vision system may adjust the sensitivity of the image processor so that the determined number of edges detected in a subsequent frame of captured image data is at or near the selected maximum number of edges.

Abstract: A vehicular vision system includes a plurality of cameras disposed at the vehicle and having respective fields of view exterior of the vehicle and being operable to capture frames of image data. Image data captured by each of the first camera is provided to an ECU via a respective ETHERNET link from the respective camera to the ECU. Control signals controlling operation of each camera are provided from the ECU to the respective camera via the respective ETHERNET link. Each camera receives from the ECU via the respective ETHERNET link a camera control signal that regulates timing of the respective camera to be synchronous with reference timing of the ECU. Regulation of timing of each camera includes starting the respective camera synchronous to the ECU reference timing and holding the respective camera synchronous to the ECU reference timing.
