In this embodiment, a method for automatically inspecting quality of a monitored picture is provided, fig. 1 is a flowchart of the method for automatically inspecting quality of a monitored picture according to an embodiment of the present invention, as shown in fig. 1, including:
s100, scanning a monitoring database and generating a picture quality inspection task, wherein the monitoring database at least stores ID information and picture quality information of a monitoring camera;
In the embodiment of the invention, at least the ID information and the corresponding picture quality information of the monitoring camera are stored in the monitoring database, specifically, a picture quality table may be established in the monitoring database, the ID information, the picture quality information, etc. of the monitoring camera may be recorded in the table, and the inspection time, etc. of the monitoring camera may also be recorded.
S200, running the picture quality inspection task and obtaining a picture quality inspection result, wherein the picture quality inspection task is used for establishing data link connection with a corresponding monitoring camera according to the ID information of the monitoring camera so as to obtain the picture quality inspection result;
In the embodiment of the invention, the picture quality inspection task is operated, and the picture quality inspection task can establish data link connection according to the ID information of the monitoring camera and the corresponding monitoring camera, and determine the picture quality inspection result based on the feedback information of the data link connection.
S300, determining picture quality information of a monitoring camera according to the picture quality inspection result, wherein the picture quality information is any one of smoothness, slowness, blocking and abnormality;
Specifically, after the picture quality inspection result is obtained, the picture quality inspection information of the monitoring camera can be determined based on the picture quality inspection result. For example, the inspection result fed back by the image quality inspection task is compared with a preset image quality level, so as to determine corresponding image quality information.
And S400, updating the picture quality information to the monitoring database.
After the picture quality information is determined, the record information in the monitoring database is updated according to the ID information of the monitoring camera, and the inspection time can be updated into the monitoring database.
Therefore, the automatic inspection method for monitoring picture quality provided by the embodiment of the invention generates the picture quality inspection task after scanning the monitoring database, and determines the monitoring picture quality according to the inspection result of the picture quality inspection task, thereby realizing automatic inspection of the monitoring picture, solving the problem of missed inspection misjudgment of manual operation in the prior art and improving the efficiency of picture quality inspection.
As a specific embodiment, scanning the monitoring database and generating a picture quality inspection task includes:
scanning the monitoring database according to preset interval time, and judging whether a monitoring camera in an inspection-free state exists in each scanning result;
If the monitoring cameras in the non-inspection state exist, the ID information corresponding to the monitoring cameras in the non-inspection state is added into a cache;
And generating a corresponding picture quality inspection task according to the monitoring cameras in the non-inspection state in the cache.
It should be understood that in this embodiment, when the service backend does not receive the operation instruction of the user, the monitoring database is scanned according to the preset interval time to generate the inspection task.
Specifically, for example, there are currently 100 monitoring cameras, and ID information and picture quality information of the 100 cameras are stored in the monitoring database. And the operation instruction of inquiring the monitoring camera is not sent by the user at present, the monitoring database is scanned according to the preset interval time, for example, the monitoring database can be scanned every 30 seconds, and a scanning result is obtained every scanning. Because the inspection state and inspection time of each monitoring camera are recorded in the monitoring database, whether the monitoring cameras in the non-inspection state exist in the current scanning result can be determined after the end of each scanning of the monitoring database. For example, if 50 monitoring cameras in an unobserved state exist in the current scanning result, the ID information of the 50 monitoring cameras is added into a cache, and a picture quality inspection task for the 50 monitoring cameras is generated. If the monitoring camera in the non-inspection state does not exist in the scanning result, the inspection task is not generated.
In this embodiment, when the user does not operate the page, the inspection tasks are sequentially established for the monitoring cameras that do not complete inspection to perform image quality judgment, and the judgment result is written into the monitoring database.
As another specific embodiment, scanning the monitoring database and generating a picture quality inspection task, further includes:
When the service rear end receives a user operation instruction, the ID information of a monitoring camera marked by a user in the monitoring database is added into a cache when the monitoring database is scanned next time according to a preset interval time;
And generating corresponding picture quality inspection tasks according to the monitoring cameras marked by the users, wherein the picture quality inspection tasks corresponding to the monitoring cameras marked by the users have higher priority than the picture quality inspection tasks corresponding to the monitoring cameras in the non-inspection state.
In this embodiment, the service back end receives the user operation instruction, that is, there is a case that the user inquires the quality of the monitoring image, in this manner, the user marks the monitoring cameras which want to inquire, for example, the user wants to inquire the quality of the monitoring images of 30 cameras, the service back end marks the monitoring cameras which the user wants to inquire in batches in the monitoring database, and meanwhile, the service back end directly inquires the monitoring database, and directly feeds back the current result after inquiry to the user, so that the service back end responds to the inquiry requirement of the user in time. And then, aiming at the monitoring cameras marked by the users, adding the ID information of the monitoring cameras marked by the users and the ID information of the monitoring cameras in an inspection-free state into a cache when the monitoring database is scanned next time, generating corresponding picture quality inspection tasks aiming at the monitoring cameras marked by the users, and further carrying out picture quality inspection again aiming at the monitoring cameras. It should be noted that, the priority of the picture quality inspection task corresponding to the monitoring camera marked by the user is higher than that of the picture quality inspection task corresponding to the monitoring camera in the non-inspection state, that is, the requirement of the user is preferentially met, after inspection is completed, the picture quality information of the monitoring camera marked by the user can be fed back to the service rear end in time, so that the service rear end can update the picture quality information of the monitoring camera marked by the user to the user in time.
It should be understood that, for the situation that the service backend receives the user operation instruction, the user marked monitoring cameras are monitoring cameras focused or queried by the user, and for the monitoring cameras focused and queried by the user, in order to respond to the user in time, the service backend firstly displays the picture quality information of the monitoring cameras focused and queried in the monitoring database to the user in time through a page, and the monitoring cameras focused and queried are taken as the monitoring cameras with marks, and as the current inspection task may not be interrupted, the current inspection task is added into a cache when the monitoring database is scanned next time, namely, the priority of the inspection tasks of the monitoring cameras marked by the user is set to be higher than the priority of the inspection tasks of the monitoring cameras in a non-inspection state, so that the picture quality information of the monitoring cameras marked by the user can be updated in time, and the query requirement of the user is met.
The flow interactive chart shown in fig. 2 is an implementation manner of the user to query the monitoring camera, when the user opens the monitoring camera page, the page will call the interface for obtaining the picture quality of the camera, the service back end queries the database, the picture quality status of the monitoring camera is fed back to the front end of the page in batch, and the batch of cameras are marked in the database as needing to judge the picture quality again. At this time, the service of camera quality judgment can perform deserialization/parallelization according to the actual situation, and establish an actual link to judge the picture quality in a single/multi-thread mode, and write the result into a database.
It should be appreciated that in this manner shown in fig. 2, the result of the user obtaining the picture quality of the monitoring cameras is returned in real time, and thus, the user can obtain without waiting for all the monitoring cameras to finish inspection.
In the embodiment of the invention, the running of the picture quality inspection task and the obtaining of the picture quality inspection result comprise:
And running the picture quality inspection task according to a preset inspection mode and obtaining a picture quality inspection result, wherein the preset inspection mode comprises single threads or multiple threads.
It should be appreciated that taking serial-parallel or single multithreading is based primarily on two factors: the server performance and the network bandwidth can be judged by the application of the service back end, and the serial-parallel or single multi-thread mode can be selected by the user specification.
For example, whether single-threaded or multi-threaded may be determined based on the manner of Table 1 below.

and obtaining a picture quality inspection result according to the data link connection state.
It should be understood that, in this embodiment, the picture quality inspection task can query the monitoring database according to the ID information of the monitoring camera to determine whether the corresponding video stream address exists, and when it is determined that the video stream address exists, establish a data link connection with the corresponding monitoring camera according to the video stream address, and obtain a picture quality inspection result according to the link connection state.
Further specifically, obtaining a picture quality inspection result according to the data link connection state includes:
judging whether a video stream can be obtained within a preset link response time;
If the video stream can be obtained within the preset link response time, determining the average frame rate of the video stream according to the obtained video stream, and recording the link response time;
If the video stream cannot be obtained within the preset link response time, the feedback link response time is overtime.
In the embodiment of the invention, because the link connection is established and whether the link connection is successful or not is required to be judged, the video stream can be obtained only under the condition that the link connection is established successfully, and therefore, the judgment is carried out according to whether the video stream can be obtained within the preset link response time.
When the video stream is obtained within the preset link response time, determining that the link connection is successful, namely calculating the average frame rate of the video stream according to the obtained video stream, and recording the response time of the link connection; if the video stream is not obtained within the preset link connection response time, the feedback of the link response time is overtime, and the video stream cannot be obtained.
Specifically, the preset link response time may be, for example, 10 seconds, if the video stream is received within 10 seconds, the average frame rate of the video stream can be determined, otherwise, the link response times out, and is marked as abnormal.
In the embodiment of the present invention, the image quality inspection task is configured to establish a data link connection with a corresponding monitoring camera according to ID information of the monitoring camera to obtain an image quality inspection result, and further includes:
