Disclosed herein is a method of detecting a vehicle speed. The method includes receiving a first vehicle image photographed by a camera at a first time; identifying an area occupied by the license plate from the first vehicle image and extracting a first number; receiving a second vehicle image photographed by the camera at a second time; identifying an area occupied by the license plate from the second vehicle image and extracting a second number; comparing the first number with the second number to determine whether the first number is equal to the second number; deciding an actual size of the number of plate; calculating a distance between the vehicle and the camera at first and second times; and calculating a vehicle speed.
