Abstract:
Systems and method are provided for controlling a vehicle. In one embodiment, a vehicle includes a camera onboard the vehicle, a lidar device onboard the vehicle, a data storage element onboard the vehicle maintaining one or more transformation parameter values associated with a pairing of the camera and the lidar device, one or more sensors onboard the vehicle, and a controller. The controller detects a stationary condition based on output of the one or more sensors, obtains a first set of image data from the camera during the stationary condition, filters horizontal edge regions from the first set, obtains a second set of the ranging data during the stationary condition, and validates the one or more transformation parameter values based on a relationship between the filtered set of the image data and the second set of the ranging data.
