Embodiment 1

[0032] see figure 1 , a kind of infrared image human body detection method that fire scene uses, comprises the following steps:

[0033] (1) Collect wide dynamic infrared image data;

[0034] (2) Perform high-frequency filtering on wide dynamic infrared images, extract all detailed information, and obtain high-frequency image data in the scene;

[0035] (3) Use a deep convolutional neural network classifier to detect human targets or local human targets in detailed images in infrared images;

[0036] (4) Give sound, light and vibration alarms to the detected targets, and remind fire rescue personnel to provide timely rescue;

[0037] The deep convolutional neural network classifier is obtained by the following steps:

[0038] (1) Collect wide dynamic infrared image data;

[0039] (2) Perform high-frequency filtering on wide dynamic infrared images, extract all detailed information, and obtain high-frequency image data in the scene;

[0040] (3) For samples of human target...

Embodiment 2

[0043] see figure 2 , an infrared image human detection device used in a fire scene, comprising an infrared camera, a high-frequency filter, a processor, an alarm device and a power supply device, the infrared camera, a high-frequency filter, a processor and an alarm device are all electrically connected to the power supply device , Infrared camera, high frequency filter, processor, alarm device and power supply device can be set on wearable and handheld devices. The shooting lens of the infrared camera uses a wide-angle lens. The alarm device is electrically connected with a warning light, and the alarm device is equipped with a buzzer and a small vibration motor inside. The detection device can be set on a wearable or handheld device, which is convenient for firefighters to carry into the fire scene. Compared with traditional rescue, it has Higher level of intelligence greatly improves rescue efficiency and accuracy.

Abstract

The invention discloses an infrared image human detection method and device used in a fire fighting scene. The infrared image human detection method used in the fire fighting scene comprises the stepsof: acquiring wide dynamic infrared image data; performing high-frequency filtering on a wide dynamic infrared image, and extracting all detailed information, so that high-frequency image data in thescene is obtained; detecting a human target or a local human target in a detailed image in an infrared image by utilizing a deep convolutional neural network classifier; and, giving a sound, light and vibration alarm on the detected target, and reminding a fire rescue personnel to rescue in time. According to the infrared image human detection method and device used in the fire fighting scene inthe invention, extracted image information can be processed through the deep convolutional neural network classifier; the human target or the local human target in an image is detected; therefore, thespeed of searching a stranded person by a fireman is increased; infrared imaging has relatively high anti-interference capability, and is difficultly influenced by delaying; therefore, the visible range of the fireman is enlarged; the stranded person can be easily rescued rapidly; and furthermore, a rescue missing condition can be reduced.

Description

technical field [0001] The invention relates to the technical field of intelligent fire protection technology, in particular to an infrared image human body detection method and device used in a fire scene. Background technique [0002] The intelligent fire protection system is an intelligent fire protection wireless alarm network service system integrating GPS (Global Satellite Positioning System), GIS (Geographic Information System), GSM (Wireless Mobile Communication System), computer, network and other modern high-tech. It successfully solves the problem of coordinated development of public facilities such as telecommunications, construction, power supply, and transportation; because the fire command center is connected to the user unit, it changes the traditional, backward, and passive methods of alarming, receiving, and handling, and realizes alarm automation. , Intelligent alarm reception, pre-planning alarm handling, network management, professional service, and mode...
