Field programmable gate array (FPGA)-based red light running automatic monitoring device

Abstract

The invention provides a field programmable gate array (FPGA)-based red light running automatic monitoring device, which belongs to an electronic and communication technology, an industrial measurement and control technology and a video image processing technology and realizes detection and image pickup of a red light running violation vehicle by using an FPGA. The FPGA is used as a core processor; an analog video signal of a charge coupled device (CCD) camera is used as an input signal source and is subjected to analog / digital (A / D) conversion to output a digital video signal; and image data is managed by the FPGA by means of an extended storage space, and motion detection of an image of a crossroad in a red light period is realized by an image motion detection algorithm, so that the red light running violation vehicle is identified, and red light running violation scene information is extracted. A working mode of the FPGA-based red light running automatic monitoring device can be selected according to actual requirements, and the device can be communicated with an external computer, so that system parameters are convenient to configure and modify. The FPGA is utilized to realize detection of a violation image without core processing units such as the computer, a digital signal processor (DSP) and the like; and the device has the advantages of simple system structure, high stability and high processing speed.

Description

technical field [0001] The invention relates to an FPGA-based automatic monitoring device for running a red light, which belongs to electronics and communication technology, industrial measurement and control technology, and video image processing technology. Background technique [0002] Urban transportation occupies an extremely important position in the development of the national economy, and has always been one of the country's key investment and construction contents. In recent years, my country's urban traffic has made great progress, but at the same time, traffic accidents have occurred more and more frequently. This not only endangers the life and property safety of the people, but also causes the country to suffer unnecessary economic losses. Running a red light is one of the most important causes of traffic accidents. Therefore, it is of great practical significance for traffic safety and management departments to monitor vehicles running a red light. [0003] T...

Problems solved by technology

But the price is high, the stability is not good, the video front-end (such as the acquisition, compression and communication of video signals such as CCD) is relatively complicated, and the reliability is not high; the industrial computer needs to be managed by a special person, especially in the monitoring point where the environment is harsh or the space is not suitable , this system is far from ideal to use

At present, most red light detection systems are implemented based on industrial computer or DSP platform. The main processing unit reads, processes and stores images, which often leads to low image acquisition and processing speed and cannot meet the requirements.
