In recent years, urban management is gradually developing towards informationization. There are corresponding processing mechanisms for illegal billboards and illegal parking in urban management, but the method of detecting illegal billboards based on machine vision is still under study. At present, the automatic detection method of illegal billboards based on machine vision is generally carried out under ideal conditions, and the experiment is carried out under a simple background. This paper takes a street in Hebei Province as the research object, and studies the illegal billboard area under natural conditions, and proposes to use the machine vision-based method to automatically detect the illegal billboards. In the surveillance image, according to the street scene detected by the computer. Image information enables status evaluation of billboard placement. The detection algorithm of this paper uses the multi-angle suggestion area to accurately locate the illegal billboards in the image, and mark the detected billboards. Compared with the direct detection of the billboard in the image, the interference of the background factor on the target area is removed, and the false detection rate is effectively reduced. In billboard detection, this paper proposes an improved region suggestion algorithm to generate higher quality candidate regions in an image for adapting to billboards of various poses under natural conditions. Experimental data shows that the algorithm has good adaptability to the detection of billboards in surveillance images.
Violation of parking is a legal term. Our country's law stipulates that there should be no-stop signs and markings, road sections with isolation facilities between motor vehicles and non-motor vehicle lanes and sidewalks, and crosswalks and construction sites. No parking; Railway crossings, sharp bends, narrow roads with widths less than 4 meters, bridges, steep slopes, tunnels, and sections within 50 meters of the above locations are not allowed to stop. In recent years, urban management is gradually developing towards information There are corresponding treatment mechanisms for illegal parking in urban management, but the method of detecting illegal parking based on machine vision is still under study. This paper takes a street in Hebei Province as the research object, and studies the illegal parking under the surveillance image. It also proposes to use the machine vision-based method to automatically detect the illegal parking. In the monitoring image, according to the street view image information detected by the computer, A status assessment of the vehicle placement can be achieved. The detection algorithm in this paper uses the multi-angle suggestion area to accurately locate the offending vehicles in the image and mark them on the detected vehicles. The experimental data shows that the algorithm has good adaptability to the detection of illegal parking in surveillance images, and effectively improves the inspection efficiency.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
