Abstract: A system and method of controlling operation of a host device in real-time, the host device operatively connected to an optical device and a radar device. The optical device is configured to obtain visual data of at least one object. The object is located at an incline, relative to the host device, the incline being characterized by an elevation angle (ϕ) and an azimuth angle (θ). The radar device is configured to obtain radar data, including a radial distance (r) of the object from the host device, the azimuth angle (θ), and a range rate (dr/dt). The controller is programmed to determine a time-to-contact for the host device and the object based at least partially on a 3-D position and 3-D velocity vector. The operation of the host device is controlled based at least partially on the time-to-contact.

Abstract: A method and apparatus for trailer recognition are provided. The method includes detecting a face of a trailer in a first and second image, taken at first and second distances respectively, generating a bounding box around the face of the trailer in the first and second images, determining a first and second set of feature points in the bounding boxes of the first and second images, determining a correspondence between the first set of feature points and the second set of feature points and a correspondence between corners of the bounding boxes and estimating at least one dimension of the trailer by performing a least squares analysis to solve for three-dimensional real world coordinates of the first and second set of features points and the corners of the bounding boxes. The method may assist an operator of a vehicle in aligning the vehicle hitch with a trailer coupler.

Abstract: A method of identifying a condition of a road surface includes capturing at least a first image of the road surface with a first camera, and a second image of the road surface with a second camera. The first image and the second image are tiled together to form a combined tile image. A feature vector is extracted from the combined tile image using a convolutional neural network, and a condition of the road surface is determined from the feature vector using a classifier.

Abstract: A method of determining a surface condition of a path of travel. A plurality of images is captured of a surface of the path of travel by an image capture device. The image capture device captures images at varying scales. A feature extraction technique is applied by a feature extraction module to each of the scaled images. A fusion technique is applied, by the processor, to the extracted features for identifying the surface condition of the path of travel. A road surface condition signal provide to a control device. The control device applies the road surface condition signal to mitigate the wet road surface condition.
