Example one
The first embodiment of the invention provides a fire disaster treatment method, which can be applied to the second embodiment of the fire disaster treatment system, and is suitable for fire disaster treatment of indoor places such as a high-voltage motor room and a host machine room of a power grid, which cannot extinguish fire through water.
Fig. 1 is a schematic flow chart of a fire hazard processing method according to an embodiment of the present invention, and referring to fig. 1, the method according to the embodiment includes steps S101 to S104.
And S101, acquiring a current indoor image in real time.
Specifically, in the step, a camera is used for carrying out video monitoring on the indoor environment, namely, continuous multiframe indoor images are shot. In addition, the monitoring room is independent of the indoor place to be monitored, and the image recognition module and the signal generation module can be arranged in the indoor place or the monitoring room.
And S102, carrying out image recognition on the current indoor image to obtain fire information, wherein the fire information comprises whether a fire occurs and a fire position.
Specifically, in the step, the image recognition module performs image recognition on the current indoor image shot by the camera, namely the current frame image, so as to obtain the fire information.
Wherein, step S102 specifically includes:
step S201, acquiring a normal indoor image.
Step S202, color conversion processing is respectively carried out on the current indoor image and the normal indoor image to obtain characteristic parameters, and the characteristic parameters comprise hue, color saturation and brightness.
Step S203, comparing the characteristic parameters of the current indoor image and the normal indoor image and preliminarily judging whether flames appear in the current indoor image according to the comparison result.
Step S204, if the flame appears in the current indoor image is preliminarily judged, extracting the characteristic parameters of the flame area in the current indoor image, matching the characteristic parameters of the flame area with the characteristic parameters of the reference flame, and further judging whether the flame appears in the current indoor image according to the matching result.
Wherein, the step S201 specifically includes:
and acquiring the indoor image at the integral point in a preset time period, wherein the default time period is at least 3 days.
And screening the indoor images at the integral point in the default time period to take the images with the largest number of pixel points as normal indoor images.
Specifically, an indoor image at a time of a few days integration is acquired, and since the indoor image employs a data sample at a time of a few days integration, the sample may exclude movement or person data. The rest is the main data of forbidden articles, the data passes through the pixel points, the pixel points with the largest number are used as effective pixel points, the pixel points with the data appearing for several days are eliminated, and then the image of the still picture can be obtained and used as a normal indoor image.

and if the characteristic parameters of the current indoor image and the normal indoor image have a difference area and two colors appear alternately on the periphery of the difference area in the current indoor image, preliminarily judging whether flames appear in the current indoor image or not.
Specifically, when a fire occurs indoors, the area of the shot frame image corresponding to flames can have a significant difference from the characteristic parameters of the normal indoor image, which is reflected in that the hue, saturation and brightness of the flames are significantly different from those of the non-flames, so that the difference area can be determined by comparing the characteristic parameters of the current indoor image and the normal indoor image. It can be understood that the characteristic parameters corresponding to different colors are different, and accordingly, whether the peripheral color of the difference area presents an image background color and a flame color which alternately appear or not can be judged by comparing adjacent frame images through continuous multi-frame indoor images acquired in real time.
In step S204, the matching the characteristic parameter of the flame region with the characteristic parameter of the reference flame and further determining whether a flame appears in the current indoor image according to the matching result specifically include:
and S301, matching the color tone of the flame area with the color tone of the reference flame to obtain a first matching degree. Specifically, the first matching degree refers to a similarity of the color tone of the flame region and the color tone of the reference flame.

It should be noted that the reference flame may be a flame in a fire condition in a reference indoor location, and the characteristic parameter of the reference flame is obtained and used as a reference standard to compare with the characteristic parameter of the flame in the current indoor image.
Specifically, since the outer periphery of the flame region is in a pulsating state, the matching range in steps S301 to S303 is the characteristic parameter matching of the flame center region. And if the first matching degree, the second matching degree and the third matching degree are all larger than the preset proportion, judging that the flame appears in the current indoor image.
For example, the preset ratio is preferably, but not limited to, 95%, and when the first matching degree, the second matching degree, and the third matching degree are all greater than 95%, it is determined that flames appear in the current indoor image.
It should be noted that, for the existing flame identification technology, in the embodiment, when flame identification is performed, a difference region is determined by comparing a current indoor image with a normal indoor image, and then, whether two colors appear alternately on the periphery of the difference region is determined to primarily determine that flame appears; and finally, comparing the characteristic parameters of the reference flame with the characteristic parameters of the difference area to finally judge the occurrence of the flame. The present embodiment carries out the secondary to the current indoor image that obtains of shooing and judges for the discernment accuracy of flame improves greatly.
Further, it is preferable that the color of the entire screen is biased toward red and yellow due to the fire, i.e., the fire illuminates the environment, in order to improve the accuracy of flame recognition. Therefore, on the basis of the secondary judgment, the color deviation and the color deviation range can be calculated, and if the color deviation and the color deviation range accord with the characteristics of flames, the flames in the current indoor image are judged.
Wherein, the step S102 further includes:
step S401, dividing the current indoor image into a plurality of squares, as shown in fig. 2, where each square corresponds to a carbon dioxide valve installed on the fire extinguishing pipe.
Specifically, each square of the image shown in fig. 2 corresponds to each area of the room, and correspondingly, each area is provided with a carbon dioxide gas valve.
It should be noted that, in the steps, the specification is performed in a field grid manner, and as more pictures shot by the camera are large and small, the drawn dividing lines are also corresponded in a near-large and far-small manner, so that the gas valves are ensured to be accurately corresponded on the pictures. How many gas valves are distributed in a chamber is divided into several grids.
Step S402, when flame appears in the current indoor image, determining a square grid corresponding to the flame, wherein the square grid is the fire position.
Specifically, each square has a square number, each carbon dioxide valve has a valve number, each valve number corresponds to a square number, when flame appears in a certain square of the current indoor image, the position information of the flame is generated according to the number of the square, and the carbon dioxide valve corresponding to the number can be determined according to the number of the square.
And step S103, generating a first alarm signal and a fire extinguishing signal according to the fire information.
Specifically, in the step, the fire information of the image recognition module is received through a signal generation module, and a first alarm signal and a fire extinguishing signal are generated according to the fire information, wherein the first alarm signal represents the condition of fire in a monitored indoor place, and the fire extinguishing signal at least comprises the position information of flame.
