Method of synchronizing multiple vehicular cameras with an ECU
A method of synchronizing cameras for a vehicular vision system includes providing camera control signals to the cameras from the ECU via respective links from the ECU to the cameras. At least two of the cameras are in communication with a hub via respective links, and the ECU is in communication with the hub via a hub link. The camera control signals are provided to one camera via a link between the ECU and the camera, and are provided to at least two other cameras via the hub link and respective links between the hub and the other cameras. The camera control signals regulate timing of the respective camera via starting the camera synchronous to the ECU reference timing. Image data is captured by each camera and provided to the ECU via the respective link or links.
Method for determining alignment of vehicular cameras
A method for determining alignment of cameras at a vehicle includes mounting first and second cameras at a vehicle and providing an image processor at the vehicle. While the vehicle is moving along the road, first image data captured via the first camera is processed to determine movement of a road feature and second image data captured by the second camera is processed to determine movement of the road feature when the road feature is present in the second image data. The determined movement of the road feature in first image data is compared to the determined movement of the road feature in second image data, and an offset of the second camera relative to the first camera is determined, with the offset caused by a rotational or translational change in position of the first or second camera relative to the other.
PERIPHERY MONITORING DEVICE, WORK MACHINE, PERIPHERY MONITORING CONTROL METHOD, AND DISPLAY DEVICE
A periphery monitoring device (2) includes cameras (C1 to C7) that detects a periphery of a hydraulic shovel (1), a periphery monitoring monitor that displays a bird's-eye image based on image information acquired by the cameras (C1 to C7), and a state switching control unit that controls mode switching between a periphery monitoring mode and a monitoring pause mode. The state switching control unit transitions to the periphery monitoring mode in a case where an input of a key-on manipulation with respect to the hydraulic shovel (1) is received in the monitoring pause mode. In the monitoring pause mode, it is possible to transition to the periphery monitoring mode in time faster than transition from a power-OFF state.
Method for improving position information associated with a collection of images
A method and system for improving position information associated with a collection of images is disclosed, more in particular, a method and system for improving position information of images obtained using a camera system including at least one camera mounted on or to a vehicle. A 3D model is constructed from an overlapping region in which at least two images obtained at different positions of the vehicle among the collection of images at least partially overlap. By comparing the 3D model to an aerial image, the position of the 3D model can be updated.
Vehicle device, calibration result determination method, and non-transitory storage medium
A vehicle device includes a video acquisition unit configured to acquire videos captured by cameras configured to capture surroundings of a vehicle; a light emission controller configured to control light emission of a light beam pattern which is emitted by light emitting devices and with which the ground is irradiated at certain positions with respect to the vehicle; an image processing unit 24 configured to generate, using the videos acquired, a bird's-eye view video including the light beam pattern; a superimposing image generation unit configured to generate a superimposing image at a position corresponding to the light beam pattern included in the bird's-eye view video; and an image determination processing unit 27 configured to detect, in the bird's-eye view video, an overlapping portion of the superimposing image and an image of the light beam pattern and determine whether camera parameters for generating the bird's-eye view video are accurately calibrated.
METHOD OF GENERATING IMAGES FOR DISPLAY FOR VEHICULAR VISION SYSTEM
A method of generating images for display includes equipping a vehicle with a vehicular vision system that includes a rearward viewing camera, an ECU and a display. The camera captures image data as the vehicle moves forward or rearward. The ECU includes an image processor that processes multiple frames of captured image data. The ECU generates, for each frame of image data captured by the camera, a left side image portion and a right side image portion. The ECU combines the left side image portions of multiple frames of captured image data and the right side image portions of multiple frames of captured image data. The combined left side image portions and the combined right side image portions are displayed at the display for viewing by the vehicle driver during a parking maneuver of the vehicle.
METHOD FOR PROVIDING CAMERA OUTPUTS TO RECEIVERS OF VEHICULAR VISION SYSTEM USING LVDS REPEATER DEVICE
A method for providing outputs to receivers of a vehicular vision system includes disposing a camera at a vehicle and disposing an LVDS repeater device at the vehicle. The LVDS repeater device includes a de-serializer, a repeater and at least two serializers. The LVDS repeater device is powered at least in part via power-over-coax from a head unit or ECU of the vehicle. The camera captures image data and outputs an LVDS camera output. The LVDS camera output is received at the LVDS repeater device and is de-serialized via the de-serializer. The de-serialized LVDS camera output is provided to the repeater and at least two outputs are provided to the serializers and are serialized. The serializers each output a respective LVDS repeater output to a respective receiver of the vehicle. The receivers include a receiver of respective ones of the vehicle head unit and the ECU.
Vehicle display apparatus and vehicle having the same
A vehicle display apparatus that includes: a sensor unit that is configured to obtain a vehicle surrounding image and sense an appearance change of a vehicle; a display unit that is configured to display the vehicle surrounding image that includes a vehicle image showing at least a portion of a vehicle appearance; and a processor that is configured to: obtain, from the sensor unit, information on the appearance change of the vehicle, based on the information on the appearance change of the vehicle, generate the vehicle surrounding image to show the appearance change of the vehicle, and control the display unit to display the vehicle surrounding image is disclosed.
Generating bird's-eye view images
A bird's-eye view image generation device includes: an image data acquisition unit that acquires periphery image data obtained by photographing a periphery of a vehicle; an obstacle information acquisition unit that acquires positional information of an obstacle detected in the periphery of the vehicle; a bird's-eye view image generation unit that generates a bird's-eye view image obtained by combining periphery images acquired by the image data acquisition unit, the periphery images having been subjected to viewpoint conversion processing so that a virtual viewpoint is positioned at a position at which the vehicle and the obstacle can be overlooked, based on the positional information of the obstacle acquired by the obstacle information acquisition unit; and a display control unit that causes a display panel to display the bird's-eye view image generated by the bird's-eye view image generation unit.
Parking Assistance Method and Parking Assistance Device
A parking assistance device includes: a surrounding-image generation circuit that generates a surrounding image that is a view of surroundings of a mobile object from above; an image display circuit that displays an assistance image at a position of an empty parking space in the surrounding image, the first assistance image indicating the empty parking space; and a turning determination circuit that determines whether the mobile object is turning. In a case where it is determined by the turning determination circuit that the mobile object is turning, the image display circuit prohibits the assistance image from being displayed.
