Abstract: In various embodiments, methods, systems, and vehicles are provided for distance determinations using cameras from different vehicles. The system includes a first camera onboard a first vehicle, providing a first image, the first image having therein an object of interest (OOI) for which a distance from the first vehicle is desired; and a second camera, providing second camera data including a second image having therein the OOI. The system further includes a control module configured to process and time synchronize first camera data and second camera data to generate a distance determination for the OOI, using the first camera data, the second camera data, and a distance between the first and second camera.

Abstract: Systems, methods, and apparatus are provided for real-time adjustment of image quality parameters. The system includes a controller configured to: acquire an image frame, having a fixed-pixel region that defines a region-of-interest, from one or more imaging devices; apply image processing techniques to determine a modified fixed-pixel region that excludes non-relevant object pixels; alter one or more image quality parameters based on statistics of pixels in the modified fixed-pixel region; and provide the altered one or more image quality parameters to the one or more imaging devices for use with subsequent image frames; wherein the one or more imaging devices produce an image that is tuned, based on the altered one or more image quality parameters, to the portions of the image in the region-of-interest that does not include the non-relevant object pixels.

Abstract: Vision sensor systems and methods detect banding and flicker. The method includes receiving camera data and identifying a light source location in a frame of camera data and assigning a luminance measure at the light source as a signal reference. A region of interest (ROI) is then associated with the light source. The frame is incremented, and then a signal to noise ratio (SNR) at the light source is calculated. A number, N of frames may be processed to identify banding when it is present, and to identify flicker when it is present. Responsive to identifying banding or identifying flicker, a response for a display system or for a machine vision system is generated.

Abstract: Methods and systems are provided for controlling camera images for a camera of a vehicle are provided. In certain examples, a vehicle includes a camera, an input unit, and a processor. The input unit is configured to obtain data pertaining to a light pattern in proximity to the vehicle. The processor is configured to at least facilitate: (i) determining the light pattern in proximity to the vehicle using the data; and (ii) providing instructions for selectively binning the camera images based on the light pattern, the selectively binning including binning first pixels together for a particular image or portion thereof, but leaving second pixels for the particular image un-binned, based on the light pattern.

Abstract: Vehicles and related systems and adaptive display adjustment methods are provided. One method involves obtaining image data captured using an initial frame rate from an imaging system onboard the vehicle, obtaining current vehicle state information, determining a representative exposure setting for the imaging system based at least in part on the current vehicle state information, determining an estimated illuminance of a surrounding environment of the vehicle based at least in part on the image data and the representative exposure setting and automatically configuring the imaging system for a different, updated frame rate based on the estimated illuminance. Thereafter, the method continues by obtaining subsequent image data captured using the updated frame rate, providing a graphical user interface including a graphical representation of the subsequent image data on a display device associated with the vehicle, and dynamically adjusting a display characteristic after configuring the imaging system for the updated frame rate.
