Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

The embodiment of the present invention discloses a method for transmitting fire scene images, which is applied to a handheld fire-fighting thermal imager. Referring to Fig. 1, Fig. 1 is a kind of flowchart of the fire scene image transmission method of the embodiment of the present invention, comprises the following steps:

Step 101, through the INS, obtain the location information of the firefighters; and generate a visible spectrum image and a thermal imaging far-infrared spectrum image of the fire scene;

In the existing technology, the handheld fire-fighting thermal imager does not have a positioning function, so that the background command center cannot obtain the location information of the firefighters. When an emergency occurs at the fire scene, the background command center may not be able to make a contingency plan in time, which may lead to Serious personal or property damage.

In addition, because the embodiment of the present invention is mainly applied to indoor fire scenes. However, satellite signals such as the Global Positioning System (GPS) and the BeiDou Navigation Satellite System (BDS) that are commonly used for position positioning have poor indoor signals, and GPS and BDS can only measure the position. Longitude and latitude information, the height information of the location cannot be measured. In addition, since most fires are unexpected emergencies, it is not convenient to arrange equipment for positioning on site in advance.

Therefore, the embodiment of the present invention may use the INS to determine the location information of the firefighters. In a preferred embodiment of the present invention, the location information may include the location information and movement trajectory of the firefighters. Among them, the INS can usually include sensors such as gyroscopes, accelerometers, and barometers, which can obtain the target's movement direction, movement speed, and height information.

It should be noted that since the use of the INS to obtain location information belongs to the prior art, details will not be described here.

It should also be noted that the thermal imaging far-infrared spectral image is a thermal image generated according to the surface temperature distribution of the target. The thermal imaging far-infrared spectral image shows the shape of the target more accurately, and can also obtain accurate image. However, compared with the visible spectrum image, the contrast between the target and the background in the thermal imaging far-infrared spectrum image is low, the edges are blurred and the noise is large, and the details of the target are not clearly reflected.

In order to obtain more accurate on-site images, the embodiments of the present invention also need to obtain on-site visible spectrum images, so as to realize the combination of on-site thermal imaging far-infrared spectrum images and visible spectrum images to generate on-site images that can accurately reflect on-site conditions.

In yet another preferred embodiment of the present invention, the generation of on-site visible spectrum images may specifically include:

Obtain the visible light channel signal of the fire scene through the visible light sensor;

A visible spectrum image of the fire scene is generated according to the visible light channel signal.

Among them, the visible light sensor can acquire rich color image information in low-light conditions without any auxiliary light source. Then, in the embodiment of the present invention, the visible light sensor is used to ensure the signal strength of the generated visible light channel, so that the visible spectrum image generated according to the signal of the visible light channel can achieve the effect of presenting the details to the greatest extent. In practical applications, the visible light sensor may specifically be a starlight level sensor.

Step 102, according to the thermal imaging far-infrared spectrum image and the visible spectrum image, superimpose and generate the scene image of the fire scene corresponding to the position information;

In the embodiment of the present invention, the dual-spectrum image fusion function is adopted, which can combine the on-site thermal imaging far-infrared spectrum image and the visible spectrum image, and on the basis of the thermal imaging far-infrared spectrum image, superimpose the visible spectrum image that can display image details , to achieve the purpose of detail enhancement, and finally generate a scene image that can accurately reflect the scene situation; it can not only help firefighters observe the scene of the fire, but also meet the needs of fire scene detection and evidence collection.

It can be understood that the location information of the firefighters can reflect the shooting location information of the simultaneously generated scene images, so that the location information of the firefighters can be associated with the scene images to distinguish fire scene images in different regions.

Step 103, transmitting the location information and the on-site image to the background command center through the mobile network.

In the embodiment of the present invention, the mobile network may specifically include a public network and a private network. The specific form of the public network may be a 4G public network or a 3G public network, and the specific form of the private network may be a 4G private network or a 3G private network. In practical application, it can be selected according to the site conditions. For example, in the case of insufficient public network signal, the solution of private network module plus mobile base station can be used. The present invention does not limit the specific form of the mobile network.

In this way, the background command center can obtain the location information of the firefighters from the fire scene and the scene images corresponding to the location information in real time through the mobile network.

In practical applications, the background command center can model the 3D motion trajectory through algorithm processing based on the acquired positioning information and motion trajectory of the firefighters, and present the firefighters' running trajectory through the 3D model. It enables the background command center to grasp the location information of firefighters in real time, and protects the life safety of firefighters to a large extent.

At the same time, the background command center can also combine the positioning information of firefighters with the scene images to determine the shooting position of the scene images, so as to grasp the fire alarm situation in different areas and locations of the fire scene. Moreover, since the location information acquired by the INS may also include height information, the background command center can also determine the height information of the shooting location, such as which floor the shooting location of the live image is located on. In this way, the background command center can generate a global scene map of the fire scene by receiving the location information from multiple handheld fire-fighting thermal imagers and the scene images corresponding to the location information, and then monitor the different fire scenes according to the global scene map of the fire scene. The location and area of the fire point, so that the corresponding search and rescue implementation plan can be made in a timely manner.

In addition, in another preferred embodiment of the present invention, the method also includes:

Measuring the temperature of the fire scene and generating a temperature curve corresponding to the fire scene;

The temperature curve is transmitted to the background command center through the mobile network.

The implementation method of the invention can measure the temperature of the fire scene and determine the surrounding high temperature area, so that the firefighters can find possible danger sources in advance. Moreover, the temperature curve can also be generated according to the measured on-site temperature, and sent to the background command center through the mobile network, so that the background command center can also understand the scene of the fire.

It can be seen that the embodiment of the present invention can use the INS to obtain the location information of firefighters; and generate the thermal imaging far-infrared spectrum image and visible spectrum image of the fire scene; and then superimpose the thermal imaging far-infrared spectrum image and the visible spectrum image A fire scene image corresponding to the location information is generated; finally, the fire scene image is transmitted to the background command center through the mobile network; in addition, the temperature of the fire scene can also be obtained, and the temperature curve of the fire scene is also transmitted to the background command center. In this way, the background command center can obtain the location information of the firefighters and the scene image corresponding to the location information in time, and grasp the location information of the firefighters, the fire scene image and the temperature of the fire scene; The location information of a handheld fire-fighting thermal imager and the scene image corresponding to the location information generate a global scene map of the fire scene to monitor the fire points in different locations and areas of the fire scene, and help the background command center to formulate a reasonable rescue plan, reducing the risk of fire. loss of persons and property.
