It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings, not all of them.
Example one
Fig. 1a is a flowchart of an indoor fire alarm warning method according to an embodiment of the present invention, where the embodiment is applicable to monitoring and warning conditions in a shooting range of a camera, and the method may be executed by an indoor fire alarm warning device, where the device may be implemented in a software and/or hardware manner, and is integrated in a server, and specifically includes the following steps:
s110, acquiring an indoor scene image from a video stream acquired by an indoor camera in real time, and identifying an indoor fire alarm according to the indoor scene image.
Wherein, indoor camera can possess the network connection environment, and the quantity can be one or more, and indoor camera has corresponding identification information. The indoor scene image may be an indoor condition image photographed by a camera.
In this embodiment, the current indoor scene image can be acquired in real time from the indoor scene video stream acquired by the indoor camera in real time, so as to identify an indoor fire alarm according to the current indoor scene image.
Optionally, the indoor fire alarm is identified according to the indoor scene image, the indoor scene image may be compared with each fire image in the fire image library, and the indoor fire alarm is identified according to the comparison result.
The fire images in the fire image library may be images of different fire degrees, for example, a scene image when a fire just occurs and a scene image in which the fire degree is continuously deepened. The comparison result can be obtained according to the similarity degree between the indoor scene image and each fire image.
In this embodiment, the current indoor scene image acquired in real time may be compared with each of the fire images to obtain a comparison result, so as to perform indoor fire alarm recognition according to the comparison result.
Optionally, comparing the indoor scene image with each fire image in the fire image library, and identifying an indoor fire alarm according to a comparison result, may include:
sequentially acquiring a current fire image from the fire image library according to the sequence of the fire degrees from low to high; calculating the image similarity between the indoor scene image and the current fire image, and judging whether the image similarity exceeds a preset similarity threshold value; if yes, determining that an indoor fire alarm is identified; and otherwise, returning to execute the operation of sequentially acquiring a current fire image in the fire image library according to the sequence of the fire degrees from low to high until the comparison of all the fire images is completed.
The current fire image may refer to an image currently used for comparison with an indoor scene image. The image similarity may refer to a degree of similarity between the indoor scene image and the current fire image, and may be specifically determined by identifying fire elements such as smoke and flames in the indoor scene image. The similarity threshold may refer to a threshold value of the similarity between the indoor scene image and the current fire image, for example, 50%.
In this embodiment, after the current indoor scene image is obtained, a fire image with the lowest fire degree is obtained from the fire image library according to the sequence of the fire degrees from low to high, the image similarity between the current indoor scene image and the current fire image is calculated, and then whether the image similarity exceeds a preset similarity threshold is determined.
It should be noted that if fire elements such as smoke and flames are not identified from the current indoor scene image, it may be determined that the current indoor is in a safe state. If it is determined that the image similarity exceeds a preset similarity threshold, i.e., it is determined that an indoor fire alarm is recognized, acquisition of a new current fire image may be stopped.
The advantage of this is that it can be identified in time with a minimum of fire, thereby providing conditions for a great reduction in personnel and property losses.
Optionally, before acquiring the indoor scene image from the video stream acquired by the indoor camera in real time, the method may further include:
responding to a registration request of the contact client, and acquiring contact identification and real-time IP (Internet Protocol) information of the contact client; and storing the binding relationship between the contact person identification and the indoor camera and the association relationship between the contact person identification and the real-time IP information.
Wherein, the registration request can be an initial registration request of the contact client. The contact identification may be identity information of the contact client.
In this embodiment, a registration request of the contact client is received, and the contact identifier and the real-time IP information of the contact client can be obtained from the registration request, so that the binding relationship between the contact identifier and the indoor camera and the association relationship between the contact identifier and the real-time IP information are stored.
Optionally, the method for warning an indoor fire alarm may further include: responding to an update registration request sent by the contact client regularly, and extracting new real-time IP information of the contact client in the update registration request; and updating and storing the association relation between the contact person identification and the real-time IP information according to the new real-time IP information.
The update registration request may be a request initiated by the contact client at each fixed interval, for example, the contact client may initiate the update registration request every 60 seconds.
In this embodiment, the current real-time IP information of the contact client is extracted from the update registration request of the contact client, and whether the current real-time IP is the same as the stored real-time IP information of the contact is checked, if so, the real-time IP information of the contact client may not be updated and stored, and if not, the association relationship between the contact identifier and the real-time IP information may be updated and stored according to the current real-time IP information.
The method has the advantages that the real-time IP information of the contact client can be acquired in time, the real-time IP information is synchronously stored, and conditions are provided for the contact client to be positioned accurately.

If the user agent identity is found to be legal, the user IP information is stored, and a registration success response 200OK is sent to the user agent. If the user agent identity is found to be illegal, a response is sent 403. If the user identity is not found to exist, a response is sent 404.
5: the user agent sends UPDATE request (UPDATE registration request) to the signaling control service unit at set time interval every 60 seconds, and in the process of UPDATE registration, if the current user IP information is different from the stored user IP information, the stored user IP information is updated; if so, no update is made. The signaling control service unit sends an update registration success response 200OK to the user agent. If the user identity is not found to exist, a response is sent 404. The updating registration process is to obtain the current IP information of the user, synchronize the IP information into the database and provide conditions for accurately positioning the client later.
The signaling control service unit can obtain the user IP information by reading the content behind the REGISTER request @. Illustratively, the REGISTER request may be as follows:
Contact:"101xxxx"<sip:101xxxx@xx.xx.xx.xx>；expires＝3600；R＝1,"102xxxx"<sip:102xxxx@xx.xx.xx.xx>；expires＝3600；R＝2,"103xxxx"<sip:103xxxx@xx.xx.xx.xx>；expires＝3600；R＝3.
