Abstract

The embodiment of the present invention relates to a fire detection method and system combining image processing technology and infrared sensor, including a digital signal processing unit, an image acquisition device, an infrared sensor and a laser ranging sensor, and accurately identifying targets through the laser ranging sensor and the infrared sensor At the same time, use the image acquisition equipment to visually identify the image data of the target area, input the surface temperature and image data into the BP neural network model and use the BP neural network to correctly identify and judge whether the target area is on fire, which can greatly improve the safety of the target area. The accuracy and stability of fire source identification in the target area. This method can be applied to forest fire detection, fire fighting, chemical plant environmental detection, agricultural assessment and other environments. The application of this method plays a great role in production and life, and also solves the It solves the technical problems that the existing fire detection system or method is limited in use places, and the detection process is easily disturbed.

Description

technical field [0001] The invention relates to the technical field of fire detection data processing, in particular to a fire detection method and system combining image processing technology and infrared sensors. Background technique [0002] At present, in the field of fire detection, the main applications are gas-type, smoke-type, temperature-type, photosensitive-type and image-type fire alarm systems. There are many factors affecting fire detection in nature, such as space height, thermal barrier, coverage, remote signal transmission, etc. Under these circumstances, traditional contact detection methods, such as temperature and smoke fire detectors, cannot be effectively used. Not only do they require high-cost support, but they also have low reliability, accuracy, and implementation. Fire detection does not work well. [0003] For example, the China Intellectual Property Office has published an invention patent with the application number 201510016281.4, the publicat...
