Highway billboard identification system and method based on vehicle-mounted camera

Abstract

The invention discloses a highway billboard identification system and method based on a vehicle-mounted camera, and the system comprises a high-definition industrial camera and a satellite positioningreceiver, and is used for photographing a highway billboard, and obtaining the satellite positioning data of a photographing position; a vehicle-mounted terminal used for preprocessing and matching the acquired pictures; the processed data is uploaded to the central service system through the wireless transmission module; and a central service system receiving the uploaded data from the vehicle-mounted terminal and is used for recording, comparing and displaying advertising board data. The vehicle-mounted camera is used for collecting conditions along the highway, and the satellite positioning receiver is used for carrying out feature recognition and positioning on billboards along the highway. The collected and identified billboard information is compared with the existing billboard GISlayer database, so that whether the collected and identified billboard is a newly-added or illegal billboard or not is quickly and accurately judged, the detection efficiency is greatly improved, andthe labor cost is reduced.

Description

technical field [0001] The invention relates to a billboard recognition system and method, in particular to a highway billboard recognition system and method based on a vehicle-mounted camera. Background technique [0002] At present, the advertising industry is growing rapidly under the background of my country's economic development, and the billboards along the expressways have gradually become hot because of their good publicity effects. At the same time, in the process of planning and setting up highway billboards, there are still loopholes in the planning and construction management of advertising facilities, insufficient supervision, and imperfect laws and regulations. Specifically, it is reflected in the following two aspects: [0003] 1. Lack of planning and management, and the phenomenon of privately building billboards is serious. [0004] The planning of advertising facilities on expressways in our country should meet the relevant requirements of the Department...

AI Technical Summary

Problems solved by technology

[0004] The planning of advertising facilities on expressways in my country should meet the relevant requirements of the Department of Transportation, but at present, there is a lack of special planning for billboards in many expressway control areas and outside expressway control areas in my country, and the phenomenon of privately erecting and building billboards is serious

[0005] 2. Lack of effective supervision of illegal billboards

[0006] At present, there are no approval procedures for the construction of billboards outside the control area along the expressway in my country, and the construction of billboards at the junction of expressways and urban areas, and the actual jurisdiction ownership is not clear, which has led to the junction becoming a frequent place for illegal billboards to be set up.

At present, the detection of billboards along the line mainly relies on manual detection and recording. It is difficult to display the detection results directly on the map, and human factors are greatly affected, which may easily lead to missed detection, false detection, and low detection efficiency.
