Embedded real-time intelligent traffic monitoring system based on video stream

Abstract

The invention provides an embedded-type real-time intelligent traffic monitoring system based on video streaming technique, which mainly comprises two DSP modules, an ARM module and an FPGA logic control module. The two DSP modules perform the high-speed real-time processing of video images. The ARM module controls the operating mode of the two DSP modules and transmits an image processing result to the peripheral equipment via a peripheral interface. The FPGA logic control module supports the coordination control of the system and the cache storage of the images. The embedded-type real-time intelligent traffic monitoring system integrates the functions of the DSP, the ARM and the FPGA, has the advantages of high computing capacity, various interfaces and flexible communication mode, is applicable to various complex traffic conditions, and has wide application range.

Description

technical field [0001] The invention relates to a traffic monitoring system, in particular to an embedded traffic video monitoring system for real-time processing of vehicles in video traffic flow based on video technology. Background technique [0002] Developed countries such as the United States, Western Europe and Japan have done a lot of research on the development of (intelligent transportation) ITS in order to solve the problem of intelligent road transportation. [0003] The ITS system realizes automatic vehicle classification and recognition, the first step that needs to be done is to detect and ingest the characteristic information of the vehicle. Since the 1970s, experts and scholars at home and abroad have developed many traffic information collection equipment, such as microwave radar detectors, induction coil detectors, ultrasonic detectors, laser detectors, infrared vehicle detectors, acoustic detectors, and magnetometer detectors. Wait. Therefore, the commo...

Problems solved by technology

[0007] Most of the current intelligent traffic video monitoring system CPUs use single-chip microcomputers or industrial computers, which can only execute timing algorithms, and use RS232 or RS485 as communication methods, which cannot meet the requirements of intelligent traffic for intersection controllers. Even if DSP video processing chips are selected, video input Mostly 1-way

There are very few 4-way or more than 8-way, the main problems are high cost, difficult development and production

Therefore, the existing video intelligent traffic monitoring system has problems such as poor adaptability, low detection accuracy, poor processor computing power, single communication mode, and narrow application range.
