Abstract
A system for calculating the sensitivity of a camera in a vehicle control system includes an internal parameter system, a controller, and a storage device. The internal parameter system is configured to determine an image coordinate of a first pixel in an image. The controller is configured to determine a point on the ground corresponding to the first pixel in the image based on external parameters. The controller is further configured to move the vehicle in a virtual world a predetermined distance, identify a second pixel in the image to which the point of the ground corresponds after the vehicle is moved in the virtual world, and calculate the sensitivity of the camera based on the distance between the position of the first pixel and the position of the second pixel. The storage device is configured to store the sensitivity of the camera.
