Abstract

See full text

A calibration system for a camera and an inertial sensor, respectively rigidly affixed to a vehicle, includes a controller having a processor and tangible, non-transitory memory on which instructions are recorded. The camera is adapted to capture one or more images and the inertial sensor is adapted to obtain motion data, including an angular velocity vector of the vehicle. The controller is configured to receive respective data from the camera and the inertial sensor. The controller is configured to perform adaptive feature selection on the one or more images, including extracting one or more regions of interest respectively from the images and calculating a respective optimal quality level for each of the regions of interest. The camera is aligned to the inertial sensor based in part on the adaptive feature selection and the respective data from the inertial sensor.
