Abstract:
1. A method for determining the velocity of a moving object, the method comprising the steps of: locating an image capture plane; capturing a first image at a first time interval from the image capture plane location, the first image comprising an image of at least one moving object; capturing a second image at a second time interval from the image capture plane location, the second image comprising an image of at least one moving object and wherein the second time interval is greater than the first time interval; determining the rate of growth of the image of the at least one moving object based on a dimensional comparison between the image of the at least one moving object from the first image and the image of the at least one moving object from the second image; and calculating the velocity of the at least one moving object based on the rate of growth of the image of the moving object relative to the image capture plane.
