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: 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.

Abstract: An enhanced light detection and ranging (LiDAR) assisted vehicle navigation system includes a global positioning system (GPS). A LiDAR device is in communication with the GPS generating and transmitting LiDAR signals reflected off a target proximate to a vehicle. Multiple vehicle sensors including at least a LiDAR sensor receive the LiDAR signals reflected off the target as a point cloud of data. A line profile of the target is used to identify if blooming is present. A characterization device performs a characterization analysis to identify an existence and extent of blooming of the LiDAR signals using the line profile of the target. A filter receives an output of the characterization device and removes the blooming if present to provide edge detection of the target.

Abstract: Methods and systems are provided for generating image data from a vehicle having a plurality of cameras. A method includes: activating, by the processor, initial video feed from each of the plurality of cameras; determining, by the processor, configuration parameters for each of the plurality of cameras based on the initial video feed; in response to a trigger event, performing frame synchronization of subsequent video feed from each of the plurality of cameras based on the configuration parameters; and generating, by the processor, the image data based on the frame synchronization.

Abstract: Systems and methods for controlling a vehicle are provided. The systems and methods receive a frame of visible image data from at least one camera of the vehicle and a frame of invisible perception data from a perception sensor. The systems and methods fuse the frame of invisible perception data and the frame of visible image data to provide a fused frame of perception data. Object detection, classification and tracking are performed using a neural network based on the fused frame of perception data to provide object detection data. Steering, propulsion and/or braking of the vehicle are controlled based on the object detection data.

Abstract: A self-cleaning sensor system of a motor vehicle includes an object sensor having a lens surface facing a region located external to the motor vehicle. The object sensor generates a signal associated with an image or a video of the region. The system further includes multiple lens treatment devices for applying remedies for removing an obscurity formed on the lens surface. The system further includes a computer having one or more processors and a computer readable medium storing instructions. The processor is programmed to determine a classification of the obscurity, in response to the processor receiving the signal from the object sensor. The processor is further programmed to generate an actuation signal, and the associated lens treatment device applies the remedy, in response to the associated lens treatment device receiving the actuation signal from the processor.

Abstract: An in-vehicle violence detection system includes a speech and non-speech audio recognition module capturing occupant threat words and non-speech audio events. In-vehicle accelerometers generate data analyzed in a shaking movement recognition module. A heart rate and breathing rate detection module measures physiological changes in occupant heart rates and breathing rhythms. An in-vehicle semantic scene recognition module analyzes occupant non-verbal interactions. Occupant threat indicators including an audible threat indicator are generated by the speech and non-speech audio event recognition module. Visual threat indicators are generated by the in-vehicle semantic scene recognition module. Physiological threat indicators are generated by the heart rate and breathing rate detection module. Vibration-based threat indicators are generated by the shaking movement recognition module. The four threat indicators are fused to estimate a threat level, consolidated by incorporating contextual information including a vehicle location and time. Different actions are taken based on the consolidated threat level.
