Embodiment Construction

[0066] Hereinafter, preferred examples of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.

[0067] like figure 1 As shown, the UAV of the present invention immediately takes off to the fire alarm point after receiving the fire alarm; after arriving at the destination, the alarm point is taken as the origin, the alarm floor is the plane, and the video is taken in a 360° cruise state with a radius of 20 meters And thermal infrared images, after the shooting is completed, the flight height is about three times the flight height of the building, the aerial photography angle is 30°, and the image of the roof and its surroundings is obtained at a downward angle of 30° towards the building; At the same time, the video and images are transmitted to the server in real ...

Abstract

The invention discloses a fire occurrence determining method and a fire occurrence determining device based on an unmanned aerial vehicle. The fire occurrence determining method comprises the steps that: the system which mainly consists of the unmanned aerial vehicle (UAV), a remote server and a control system on the ground is adopted, the unmanned aerial vehicle flies to a fire alarm region according to GPS position information of a fire alarm point, shoots a field video image and a thermal infrared image of the alarm point, and sends the field video image and the thermal infrared image to the remote server through a 4G mobile cellular network; the remote server receives data and obtains the real-time field video and thermal infrared image; and a result whether a fire occurs is obtained through naked eye identification or subjecting the thermal infrared image to comparison by means of a classifier. The fire occurrence determining method and the fire occurrence determining device can send out the unmanned aerial vehicle timely after receiving an alarm, save a large amount of manpower and material resources of fire fighting, can master field condition of the fire occurrence point quickly, provide reliable and effective real-time information for carrying out the rescue operation, and compensate for the defect that the existing method of confirming fire occurrence lacks of a method of confirming fire occurrence through aerial photography by means of the unmanned aerial vehicle.

Description

technical field [0001] The invention relates to a method for confirming the occurrence of a fire, in particular to a method for confirming the occurrence of a fire in the field of unmanned aerial vehicle research. Background technique [0002] Fire refers to the disaster caused by burning out of control in time or space. Among various disasters, fire is one of the main disasters that most frequently and commonly threaten public safety and social development. [0003] According to statistics from the Fire Department of the Ministry of Public Security, in 2014, a total of 395,000 confirmed fire alarms were received across the country, resulting in 1,817 deaths, 1,493 injuries, and direct property losses of 4.39 billion yuan. However, the number of calls received is much more than that. If, without confirming whether a fire has occurred, the fire department rushes to the rescue blindly, it will waste a lot of manpower and material resources for fire fighting, and even the ala...
