System for automatically monitoring illegally-parking vehicles and compressed transmission based on field programmable gate array (FPGA)

Abstract

The invention relates to a system for automatically monitoring illegally-parking vehicles and compressed transmission based on field programmable gate array (FPGA), belonging to the signal processing technology, the communication technology and the video image processing technology, and realizes automatic detection and image remote transmission on illegal parking vehicles in a detecting area by utilizing an FPGA chip as a digital image collection and processing unit. In the system, a monitor area in a charge coupled device (CCD) video image is determined according to an actual application environment, and firstly, a background image of an interested area is saved when monitoring is started; then, when each frame comes, the fact that whether a vehicle comes or not is judged according to the difference of the current frame and the background frame; a timer is started when a vehicle comes, if the difference constantly exists in a regular period, a vehicle is judged to be illegally parked in the monitor area, and the next frame image containing information of the illegally parking vehicle is compressed through a special image compression chip and transmitted to a remote control center.

Description

technical field [0001] The invention relates to an FPGA-based automatic monitoring and compression transmission system for illegal parking of vehicles, which belongs to signal processing technology, communication technology, and video image processing technology. Parked automatic detection and image remote sending. Background technique [0002] In recent years, with the strengthening of the country's economic strength, my country's urban transportation has been greatly developed, and the per capita vehicle occupancy rate has also been greatly increased. However, due to the large amount of funds needed for road construction and traffic network management and other infrastructure construction, and the construction period is long, its development speed is still far lower than the increase speed of transportation means, resulting in more and more frequent traffic accidents and traffic jams. It endangers the life and property safety of the people, and causes unnecessary economic...
