Abstract

The invention discloses a vehicle traveling speed and license plate recognition system and method based on TOF imaging. The system comprises a monitoring equipment mounting frame and a TOF camera, andan image processing computer arranged in a monitoring center. The monitoring equipment mounting frame comprises a column and a mounting bar fixedly connected at the top of the column and arranged perpendicularly to the column, and a TOF camera is mounted at the top of the mounting bar; The vehicle traveling speed method comprises the following steps: step A1, video acquisition and transmission; step A2, vehicle traveling speed identification; The license plate recognition method comprises the following steps: step B1, video acquisition and transmission; step B2, license plate recognition. Theinvention has the advantages of low cost, convenient installation and maintenance of the system, high recognition accuracy of vehicle traveling speed and high recognition accuracy of vehicle licenseplate, can effectively manage and control the road traffic, reduce traffic accidents, and avoid light pollution and safety hidden danger caused by visible light supplementation when vehicle speed measurement and vehicle license plate recognition are carried out by using visible light.

Description

technical field [0001] The invention belongs to the technical field of video detection, and in particular relates to a vehicle speed and license plate recognition system and method based on TOF imaging. Background technique [0002] In today's society, intelligent transportation system is the development trend of road transportation. The continuous development and continuous improvement of the visual intelligent traffic monitoring system has laid a good foundation for the practical application of the management system of vehicle road transport infrastructure. In recent years, my country's intelligent transportation industry has developed rapidly. As an important component of intelligent transportation, the vehicle identification system is widely used in off-site law enforcement in cities. However, there are still many problems in the current vehicle identification system. The traditional vehicle identification system is based on LED supplementary light. system, and adopts th...
