Problems solved by technology

[0004] The basic data of the intelligent service area is the real-time data collection of vehicle flow and human flow. This information plays an important role in arresting criminals, controlling the spread of diseases, and preventing illegal transportation of dangerous goods. Traditional service areas do not The data is collected in a centralized manner, and the informatization is relatively low, which urgently needs to be further improved to meet people's demand for intelligent services

Embodiment 1

[0032] The present invention provided herein is a flow monitoring system based on a high-definition infrared camera, and the flow monitoring system includes a front subsystem, a network subsystem and a central subsystem, wherein,

[0033] The front-end subsystem includes network high-definition cameras deployed at various locations in the service area. The network high-definition cameras are connected to large-capacity storage to transmit audio and video data to the storage. The front-end subsystem is used to detect the flow of people and vehicles Data, to manage the entry and exit of vehicles and tourists;

[0034] Described network subsystem adopts hotspot wifi to carry out networking to the equipment of front-end subsystem, transmits in the central subsystem through LAN network;

[0035] The central subsystem is a passenger flow analysis and management platform, including a server and a controller, which realize front-end data access, storage, query, system operation and ma...

Embodiment 2

[0054] As another improvement point of the present invention, through the system, the user can obtain face information, and the network high-definition camera adopts snapshot and monitoring combined with face recognition. The process of sensing the body temperature of tourists through the infrared dome camera mentioned above is:

[0055] First, the original infrared image is acquired through the bolometric sensor of the infrared dome camera; then the image is subjected to temperature normalization processing to eliminate the influence of the ambient temperature on the change of the body temperature of tourists; finally, the facial features are extracted and the threshold is determined by setting the Whether the body temperature is abnormal.

[0056] Furthermore, in the process of normalizing the temperature of the image, a reference ambient temperature is first set, and the temperature low point in the acquired original infrared image is used as the ambient temperature of the ...

Abstract

The invention relates to the application of an intelligent highway technology in a service area, in particular to a flow monitoring system based on a high-definition infrared camera. The system comprises a front-end subsystem, a network subsystem and a central subsystem, wherein the front-end subsystem comprises network high-definition cameras deployed at all positions of the service area, the network high-definition cameras are connected with a large-capacity memory to transmit audio and video data to the large-capacity memory, and the front-end subsystem is used for detecting pedestrian flow and traffic flow data and managing vehicles and tourists to get in and out; the network subsystem adopts hot spot wifi to carry out networking on equipment of the front-end subsystem, and transmits the networking information to the central subsystem through an LAN network; a network high-definition camera is deployed in an expressway service area, data collected by the camera is sent to a cloud server through a wireless network or in combination with a wired network, image data is processed through a controller, and information such as pedestrian flow and vehicle flow is obtained.

Description

technical field [0001] The invention relates to the application of intelligent highway technology in a service area, in particular to a flow monitoring system based on a high-definition infrared camera. Background technique [0002] The flow of vehicles and people in the expressway service area is huge. The traditional service area is only used as a rest area for drivers, providing basic services such as refueling, temporary rest, toileting, catering, and auto repair for long-distance vehicles and tourists. After years of development , the service area has gradually developed into a new type of commercial area featuring rich business forms and complete functions such as business management, leisure and entertainment, value-added marketing, and e-commerce featuring the Internet and Internet of Things informatization. [0003] The expressway smart service area will be based on a new generation of information and communication technology (TCT), integrating cloud computing (SaaS...
