The embodiments and features of the embodiments of the present invention may be arbitrarily combined with each other without conflict. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.

Furthermore, the term "comprises" and any variations thereof, which are intended to cover non-exclusive protection. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
In the embodiment of the present invention, the "plurality" may mean at least two, for example, two, three, or more, and the embodiment of the present invention is not limited.
As described above, in the prior art, when video stream data of a plurality of scenes are acquired, the video stream data are sorted first, and then the video stream data sorted most forward is sent to all the video stream processing units, so that all the video stream processing units process and judge the video stream data sorted most forward, and when it is determined that the processing is possible, the video stream data sorted most forward is processed, which results in a waste of computing power of other processing units, and a low efficiency of processing the video stream data of the plurality of scenes.
In view of this, the present invention provides a method for processing a multi-scene video stream, by which a scene of a multi-path multi-scene video stream data can be determined in advance, and then the video stream is sent to a video stream processing unit corresponding to the multi-scene video stream data, so that the efficiency of checking that the video stream data belongs to a certain scene is improved, and the efficiency of processing the multi-scene video stream is improved.
After the design idea of the embodiment of the present invention is introduced, some simple descriptions are made below to application scenarios to which the technical solution of the method for processing a multi-scene video stream in the embodiment of the present invention is applicable, and it should be noted that the application scenarios described below are only used for illustrating the embodiment of the present invention and are not limited. In specific implementation, the technical scheme provided by the embodiment of the invention can be flexibly applied according to actual needs.
In an actual implementation process, a plurality of scenes for acquiring high-density crowd image data information may be set at different places and at different heights, and specifically, the scenes may be shopping malls, campuses, high-speed rail stations, subway stations, and the like.
Referring to fig. 1, in an embodiment of the present invention, a computer device may receive a plurality of capturing devices for capturing video data of different places, which are set in a shopping mall, specifically, the capturing devices may be cameras or video capturing devices including video capturing accessories and cameras, where the video capturing accessories include lenses, holders, decoders, supports, protective covers, video distributors, and the like. It should be noted that fig. 1 is only exemplarily shown with one computer device and 3 video capture devices. In a specific implementation, a plurality of video capture devices, for example, 5 video capture devices, may transmit video data to the computer device, or 10 video capture devices may transmit video data to the computer device. Of course, a plurality of computer devices may interact with a plurality of different video capture devices, which is not limited in the embodiment of the present invention.
In a specific implementation process, real-time video data acquired by an acquisition device (e.g., a camera) with a definition of 1080P and a length of less than 9 meters may be used as real-time video data of a scene, data acquired by a camera with a definition of 8K and a length of more than 9 meters may be used as real-time video data of a scene, and of course, real-time video data acquired by an acquisition device with a definition of 1080P and a length of more than 9 meters may be used as real-time video data of a scene. That is to say, the real-time video data of multiple scenes in the embodiment of the present invention may be understood as the real-time video data collected by the video collecting devices with different set heights and different collection definitions.
Further, after the real-time video data acquired by the plurality of acquisition devices is obtained, the scene parameters corresponding to the acquisition devices can be synchronously acquired, the scene parameters are used for representing the setting parameters of the video acquisition devices, for example, the setting height of the video acquisition devices can be 7 meters, the definition is 1080P, and then the real-time video data and the scene parameters are synchronously packed into one path of video stream data to be transmitted, so that the computer device can acquire the path of video stream data. In a specific implementation process, the multiple paths of multi-scene video stream data acquired by the computer device may be in the aforementioned acquisition mode, and the acquired video stream data includes real-time video data and scene parameter information.
In the embodiment of the invention, after the video stream data is obtained, the computer equipment can firstly carry out scene check on the input multi-path multi-scene video stream data, so that the scene identification information corresponding to the video stream data can be determined, and then the index identification of the corresponding video stream processing unit is determined according to the scene identification information.
In a specific implementation process, the computer device may set a plurality of different video stream processing units in advance for a plurality of scenes to be processed, where the video stream processing units may be understood as algorithm models for different scenes. It should be noted that, in the embodiment of the present invention, for convenience of description, the processing library including multiple video stream processing units may be referred to as a multiple video stream processing unit, and a processing mechanism of the multiple video stream processing unit is multi-thread concurrent processing.
The method for processing a multi-scene video stream according to the embodiment of the present invention is described below with reference to the method flowchart shown in fig. 2, and the steps shown in fig. 2 can be executed by the aforementioned computer device in fig. 1. In an implementation, the computer device may be a server, such as a personal computer, a midrange computer, a cluster of computers, and so forth.
A plurality of video stream data corresponding to a plurality of scenes is received, step 201.
In the embodiment of the present invention, the computer device may receive a plurality of video stream data corresponding to multiple scenes, specifically, the video stream data of the multiple scenes received by the computer device may be a plurality of video stream data corresponding to multiple scenes belonging to the same application scene (for example, a shopping mall), for example, video stream data acquired by a video acquisition device including a video acquisition accessory and a camera, of a plurality of different scenes set in a department store; or multiple video stream data corresponding to multiple scenes of different application scenes, for example, the computer device may receive video stream data collected from a video capture device disposed in an airport and video stream data collected from a video capture device disposed in a high-speed rail station.
In a specific implementation process, the computer device receives a plurality of video stream data corresponding to a plurality of scenes, wherein each video stream data in the plurality of video stream data at least comprises real-time video data corresponding to one scene and scene parameter information corresponding to one scene, and specifically, the real-time video data at least comprises crowd flowing audio/video information and crowd conversation audio/video information.
Step 202: according to scene parameter information included in each video stream data in the plurality of video stream data, synchronously performing scene parameter verification processing on the plurality of video stream data to determine scene identification information corresponding to each video stream data.
In the embodiment of the present invention, it may be determined whether scene parameter information included in each of the plurality of pieces of video stream data and any setting parameter information of the plurality of paths of video stream processing units have an association, and if the scene parameter information included in a first piece of video stream data among the plurality of pieces of video stream data and the setting parameter information of the first piece of video stream processing units have an association, scene identification information corresponding to the first piece of video stream data is determined.
In a specific implementation process, the method for checking and processing the scene parameter included in any one of the video stream data may be to determine whether the scene parameter information included in the video stream data and any setting parameter information of the multiple video stream processing units have a relationship, and specifically, in the embodiment of the present invention, the relationship may be that the scene parameter information and the setting parameter information have partial information that is the same or information that is completely the same, and certainly, the scene parameter information and the setting parameter information have a corresponding relationship.
For example, when it is determined that the scene parameter information of the a video stream data is 5 meters in set height and 1080P in video definition, it may be determined whether there is setting parameter information of 5 meters in set height and 1080P in video definition from a place (for example, a storage unit or a database) where the setting parameter information corresponding to the multiple video stream processing unit is stored.
Further, in the embodiment of the present invention, when it is determined that the scene parameter information included in the first video stream data of the plurality of video stream data has an association relationship with the setting parameter information of the first video stream processing unit, the scene identification information corresponding to the first video stream data may be determined. The scene identification information may be a character, a number, a letter, or the like, which is not limited in the embodiment of the present invention.
For example, continuing with the foregoing example as an example, when it is determined that the setting parameter information of the first video stream processing unit is 5 meters in setting height and 1080P in video definition, it may be determined that the a video stream data has an association with the first video stream processing unit, and thus the scene identification information, i.e., 1, corresponding to 5 meters in setting height and 1080P in video definition may be taken as the scene identification information of the a video stream data.
In this embodiment of the present invention, the foregoing method may be adopted to perform scene parameter verification processing on multiple pieces of video stream data synchronously according to scene parameter information included in each piece of video stream data, so as to determine scene identification information corresponding to each piece of video stream data.
In the embodiment of the present invention, when the foregoing method is adopted to perform scene parameter verification processing on multiple pieces of video stream data synchronously, and when it is determined that the scene parameter information included in a second piece of video stream data in the multiple pieces of video stream data does not have a relationship with the setting parameter information of any video stream processing unit, the second piece of video stream data is discarded.
In a specific implementation process, there may be video stream data that cannot be processed by the multiple video stream processing units in the multiple video stream data received by the computer device, and during the scene parameter verification processing, the video stream data that cannot be processed by the multiple video stream processing units is determined, so that the video stream data is discarded. In such a mode, the received multiple video stream data can be judged in parallel in advance, and the processing efficiency of the multiple video stream data is improved.
Step 203: and triggering a video stream processing unit corresponding to the scene identification information in the multi-path video stream processing unit according to the scene identification information corresponding to the video stream data, and processing the real-time video data in the video stream data so that the multi-path video stream processing unit can process a plurality of video stream data in parallel.
In the embodiment of the present invention, when the scene identification information corresponding to the video stream data is obtained, the video stream processing unit corresponding to the scene identification information in the multi-path video stream processing unit may be triggered to process the real-time video data in the video stream data, so that the multi-path video stream processing unit may process a plurality of video stream data in parallel.
In a specific implementation process, the unit index information of the video stream processing unit corresponding to the scene identification information may be determined according to the scene identification information and a preset rule, and then the video stream processing unit corresponding to the unit index information in the multiple paths of video stream processing units may be triggered according to the unit index information to process real-time video data in the video stream data.
In the embodiment of the present invention, the scene identification information may be understood as identification information of video stream data, the unit index information may be understood as identification information of a video stream processing unit, and then the scene identification information and the unit index information may be matched by a preset rule, so that a corresponding video stream processing unit capable of processing the video stream data may be determined. The preset rule may match the scene identification information according to a corresponding matching pair of the predetermined scene identification information and the unit index information, so as to determine the corresponding unit index information.
Further, the multi-path video stream processing unit performs parallel processing on the plurality of video stream data, and may obtain processing information of the plurality of video stream data at the same time, for example, heat map information of the crowd flowing corresponding to the video stream data.
