Vision-Based Vehicle Speed Measurement Method

摘要

This paper introduces a novel method for vehicle speed detection based exclusively on visual information. The proposed system consisting only of a digital camera and a computer is able to identify both the speed of the passing vehicle and its licence plate numbers, which makes it an interesting alternative to existing and expensive photoradar systems. The principle of operation is simple: vehicles are identified by their licence plates and their speed is measured based on the vertical difference of their position in consecutive images. An experimental evaluation shows the high accuracy of vehicle speed measurement, comparable to the one provided by comercially available radar-based systems.
