Closed large-area intelligent monitoring system based on code recognition and recognition method thereof

Abstract

The invention provides a closed large-area intelligent monitoring system based on code recognition and a recognition method thereof. The system comprises an identification subsystem and a video subsystem. The video subsystem carries out authorization registration on people to be registered in a non-closed area. During registration, the unique number is sprayed to an authorized person through ultraviolet or infrared paint, after spraying, the number and a camera shoot calibration object data, the calibration object data are sent to an image index server to load the number and a registration photo, and storage and filing are carried out for checking during identification of the identification subsystem. And the identification subsystem is used for performing identification judgment, classification and processing according to the serial numbers and the pictures shot by the AI camera in the video subsystem in a closed large area in real time. According to the system, the invisible light ismarked with a unique number, high-speed irradiation and shooting are carried out, the number is accurately identified in a long distance, high-speed checking and identification are carried out, and an AI closed area intelligent monitoring system is adopted, so that the identification accuracy and efficiency are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of identification, and more specifically relates to a closed large-area intelligent monitoring system based on code identification and an identification method thereof. Background technique [0002] With the advancement of technology, a large number of monitoring devices with AI functions have emerged. However, within the scope of a closed large area (closed large area can include museums, stadiums, conference centers, prisons, government buildings, parks, schools, shopping malls, etc., but not limited to these), there are many people and large mobility, How to accurately and quickly identify unauthorized personnel and record the behavior track of authorized personnel among thousands of personnel is very important for improving security and monitoring effects. At present, the technologies that can realize environmental identification and monitoring mainly include: [0003] 1. Based on image processing and ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a closed large-area intelligent monitoring system based on code recognition and its recognition method, which overcomes the need to compare the photos of people one by one in the existing AI recognition. The problem of sharp decline with the increase of the number of people in the closed area, the present invention uses a unique number of non-visible light marking, using a specific wavelength of invisible strong light LED, high-speed irradiation and shooting, long-distance accurate identification number, high-speed verification AI The closed area intelligent monitoring system effectively improves the accuracy and efficiency of identification
