    Abstract: A vehicle control system for automated driver-assistance includes a low-resolution color camera that captures a color image of a field of view at a first resolution. The vehicle control system further includes a high-resolution scanning camera that captures a plurality of grayscale images, each of the grayscale images at a second resolution. The second resolution is higher than the first resolution. The grayscale images encompass the same field of view as the color image. The vehicle control system further includes one or more processors that perform a method that includes overlaying the plurality of grayscale images over the color image. The method further includes correcting motion distortion of one or more objects in the grayscale images. The method further includes generating a high-resolution output image by assigning color values to one or more pixels in the grayscale images based on the color image using a trained neural network.

    Abstract: Method and systems for image deblurring in a vehicle. The methods and systems include determining a point spread function based on vehicle motion data and a depth map received from vehicle motion sensors and a depth sensor. A deblur matrix is calculated based on the point spread function. A blurred input image, received from an imaging device, is deblurred based on the deblur matrix to thereby provide a deblurred output image. A function of the vehicle is controlled based on the deblurred output image.

    Abstract: A vehicle, system and method for aligning a sensor with the vehicle. A first inertial measurement unit (IMU) associated with the vehicle obtains a first measurement of a kinematic vector of the vehicle. A second IMU associated with the sensor obtains a second measurement of the kinematic vector. A processor determines a current relative orientation between a first reference frame associated with the vehicle and a second reference frame associated with the sensor from the kinematic vector, determines an alignment error between the sensor and the vehicle based on the current relative orientation and a specified relative orientation, and adjusts the sensor from the current relative orientation to the specified relative orientation to correct for the alignment error.

    Abstract: A method and apparatus for calibrating a LiDAR system at a first location with a radar system at a second location. A calibration target is placed at a location and orientation with respect to the LiDAR system and the radar system. Coefficients of a plane of the calibration target are determined in a frame of reference of the LiDAR system. Coordinates of the calibration target are determined in a frame of reference of the radar system. A cost function is composed from a planar equation that includes the determined coefficients and the determined coordinates and a relative pose matrix that transforms the frame of reference of the radar system to the frame of reference of the LiDAR system. The cost function is reduced to estimate the relative pose matrix for calibration of the LiDAR system with the radar system.
