Intelligent fire-fighting monitoring and rescuing method based on indoor camera

Abstract

The invention relates to the technical field of fire rescue, and provides an intelligent fire-fighting monitoring and rescue method based on an indoor camera, and the method comprises the steps: building a three-dimensional visual map through three-dimensional modeling according to a building drawing; determining space coordinates of an indoor camera and displaying the space coordinates in a three-dimensional visual map; establishing a corresponding relationship between the personnel image and the personnel spatial position; positioning the floor and the specific position of personnel, and obtaining people flow information in the building; and making a fire-fighting plan and / or a fire-fighting rescue scheme according to the people flow information in the building. By means of indoor three-dimensional modeling, a camera, a mathematical model and other technologies, the real-time position and dynamic continuous information of personnel in a supermarket or a complex building are obtained,and technical support is provided for merchants and firefighters to master personnel dynamic information and shopping trend behaviors in real time; once a fire-fighting fire occurs, barrier-free or optimal path selection, prevention and control integration and targeted rescue are ensured by means of the method, and the method is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of firefighting and rescue, in particular to an intelligent firefighting monitoring and rescue method based on an indoor camera. Background technique [0002] Urban fire protection is an important task to protect the country's collective personal property and the safety of residents' lives. With my country's economic development and social progress, people's living standards continue to improve, urban construction is changing with each passing day, cities and buildings are expanding rapidly, and infrastructure is complex and diverse, so the requirements for fire protection work are getting higher and higher. Firefighting forces protect people's lives and property Safety is becoming more and more important. [0003] With the rapid development of urbanization in my country, large-scale complexes, chemical enterprises, underground and high-rise buildings continue to emerge, especially large-scale shopping malls...

Problems solved by technology

At present, a smart fire truck based on a 3D camera is proposed, which evaluates the optimal path based on the chromaticity and depth information of the target object, and solves the inconvenience of existing manual fire fighting to a certain extent, but only for fixed objects The information acquisition is relatively effective, and it cannot be applied to indoor fires in real time, so there are certain limitations; it is proposed to apply indoor cameras to early warning monitoring, and identify various critical situations such as thieves intrusion, fire, and water leakage through monitoring video analysis. It does play a role in prevention, alarm and fire general position judgment. However, when fires occur in large shopping malls and complex buildings, the flow of people is surging, coupled with the dynamic changes of the fire, it is still impossible to obtain the changes in the flow of people in real time, so that the fire commanders can formulate reasonable and scientific measures. It is proposed to use machine vision smart cameras for fire detection, monitoring of major hazards and fire alarms, which can automatically extract, analyze and understand useful information from a single image or image series, but its computing power is limited and requires external The cost of equipment is relatively high, and it does not combine 3D map information, so it is impossible to grasp the specific spatial location of personnel, which is not conducive to actual promotion and application.
