1. A computer implemented method for detecting vehicle movement, the method comprising:

  • receiving, with one or more computing devices, first image data representative of a first vehicle'"'"'s wheel;

    determining, with the one or more computing devices and based on the first image data, a first location of a first portion of the wheel;

    receiving, with the one or more computing devices, second image data representative of the wheel captured subsequent to the capture of the first image data;

    determining, with the one or more computing devices and based on the second image data, a second location of the first portion of the wheel;

    generating, with the one or more computing devices, an initial determination whether the first vehicle is in motion;

    assigning, with the one or more computing devices, a confidence level to the initial determination;

    determining the confidence level satisfies a threshold value; and

    upon determining the confidence level satisfies the threshold value;

    calculating, with the one or more computing devices, a value based on an angular distance between the first location and the second location of the first portion;

    determining, with the one or more computing devices and based on the value, whether the first vehicle is in motion; and

    providing a signal that the first vehicle is in motion.
