Method for verifying speed of appropriate vehicle, involves calculating image angle based on displacement of vehicle in images taken at preset subsequent times and intrinsic parameters of camera, and comparing with object angle

摘要

The method involves creating several images of vehicle that pass through object region of camera (K) in roadway at the preset subsequent times. The location and orientation of vehicle with respect to roadway are detected. The distance traveled by vehicle between preset subsequent times in relative to camera is calculated as a function of speed based on travel direction so as to calculate object angle. The image angle is determined based on displacement of vehicle in images and intrinsic parameters of camera, and is compared with object angle for determining velocity of vehicle.
