Abstract

The invention relates to a video-based illegal parking monitoring system, which mainly solves a technical problem of lack of vehicle owner tolerance existing in the prior art. The technical problem is well solved by adopting the technical scheme that the video-based illegal parking monitoring system comprises cameras arranged in a distributed manner, a communication unit, a storage medium and a processor, and the processor is used for executing a violation vehicle detection and recognition program so as to execute the steps of reading video data of the cameras, performing mixed Gaussian background modeling to obtain a regular background image in adjacent video images, comparing an input image I(x, y) and the background image, and separating a vibration vehicle motion foreground image; judging illegal parking by adopting a continuous inter-frame displacement method; performing corrosion and expansion, filtering and smoothing and contour extraction to obtain a contour, acquiring bounding rectangle, performing length-width ratio screening to obtain an illegal parking vehicle image; extracting license plate information of the illegal parking vehicle; and calling a communication unit to notify a vehicle owner to eliminate the illegal parking behavior within an allowable time threshold. The video-based illegal parking monitoring system is used in illegal parking detection.

Description

technical field [0001] The invention relates to the field of violation monitoring, in particular to a video-based monitoring system for illegal parking. Background technique [0002] Video surveillance technology has been developed so far and has been applied in many fields. Specifically in terms of road traffic monitoring, there are many existing systems that accurately detect and record violations such as speeding, driving, and running red lights. However, the detection technology based on illegal parking is relatively lagging behind. For illegal parking detection technology, it is necessary to give car owners a certain tolerance. [0003] The existing illegal parking detection technology ignores the time tolerance for the owner's elimination behavior, and the robustness is low, and it cannot realize the illegal parking monitoring function with good effect and high accuracy. Therefore, it is necessary to provide a monitoring system for parking violations that provides to...
