    Abstract: Examples of techniques for dynamically selecting a batch size used in vehicle camera image processing are disclosed. In one example implementation, a method includes generating, by a processing device, a batch table and a mode table. The method further includes determining, by the processing device, image processing performance requirements for a current mode of a vehicle using the mode table, the vehicle comprising a plurality of cameras configured to capture a plurality of images. The method further includes selecting, by the processing device, a batch size and a processing frequency based at least in part on the image processing performance requirements for the current mode of the vehicle. The method further includes processing, by an accelerator, at least a subset of the plurality of images based at least in part on the batch size and processing frequency.

    Abstract: A method for determining wetness on a path of travel. A surface of the path of travel is captured by at least one image capture device. A plurality of wet surface detection techniques is applied to the at least one image. An analysis for each wet surface detection technique is determined in real-time of whether the surface of the path of travel is wet. Each analysis independently determines whether the path of travel is wet. Each analysis by each wet surface detection technique is input to a fusion and decision making module. Each analysis determined by each wet surface detection technique is weighted within the fusion and decision making module by comprehensive analysis of weather information, geology information, and vehicle motions. A wet surface detection signal is provided to a control device. The control device applies the wet surface detection signal to mitigate the wet surface condition.

    Abstract: A vehicle includes at least one image capture device and a user display configured to display images receive from the at least one image capture device. The vehicle also includes a controller programmed to generate a user prompt to set a home vehicle position in response the vehicle entering a first parked state. The controller is also programmed to store at least one reference image indicative of an area in a vicinity of the vehicle corresponding to the home vehicle position. The controller is further programmed to collect a current image corresponding to a current vehicle position in response to a subsequent approach toward the vicinity, and compare the current image to the reference image. The controller is further programmed to generate a user display depicting the vicinity, the current vehicle position, and the home vehicle position.

    Abstract: Methods and systems are provided for analyzing tires of a vehicle utilizing camera images from one or more cameras mounted on the vehicle (or infrastructure). In one example, the method includes obtaining camera images of one or more tires of a vehicle, utilizing one or more cameras that are mounted on the vehicle, during operation of the vehicle; and processing the camera images, via a processor, in order to generate an analysis of one or more of the tires based on the images that were obtained via the one or more cameras that are mounted on the vehicle.

    Abstract: A vehicle guidance system facilitates maneuvering of an autonomous vehicle with respect to an object in a scene. The vehicle includes a steering apparatus having a range of angular positions and a multitude of actuators for controlling the dynamics of the vehicle. The system includes a steering angle sensor, a camera device, and a video processing module. The sensor is configured to monitor the angular position of the wheel. The device is configured to capture an original image of a scene having the object. The module is configured to receive and process the original image from the device, detect the object in the original image, receive and process the angular position from the sensor, generate a dynamic trajectory based on at least the angular position, orientate the dynamic trajectory with regard to the object, and operate at least one of the actuators to guide the vehicle along the dynamic trajectory.
