Referring to fig. 1, a method for displaying a video in a virtual scene includes:
s11: a video display indication is obtained.
The video display instruction may be understood as a real-time video for instructing to display one or more target cameras in an interactive picture of the virtual scene, and specifically, if a main body for operating the method is an electronic device, the video display instruction may be specifically understood as a real-time video for instructing the electronic device to display one or more target cameras in an interactive picture of the virtual scene. It may be generated by other devices and sent to the electronic device, may be generated by the electronic device, or may be generated under the interactive operation of the user, and thus, as long as the indication capable of indicating the real-time video display is generated, no matter what form, or what device, the description of the embodiment is not deviated.
The real-time video may be understood as a current video that changes in real time with time, and may be transmitted and played in a media streaming manner, or may be combined with a buffer or other means. Meanwhile, the real-time video may be a real-time video itself collected by a camera, and in some embodiments of this embodiment, the real-time video may also be obtained by further processing according to the real-time video collected by the camera, for example, the real-time video may be subjected to noise reduction processing, or may be subjected to cutting processing, or may be subjected to color processing, and the like.
The target camera can be understood as a camera which is selected from a plurality of cameras and is required to display real-time videos on an interactive interface. In a specific implementation process, the video display indication may carry an identifier of the camera in reality, where the identifier may be, for example, a preset identification number, a uniquely identified device number, or other information bound to the camera, where the other information may be, for example, a camera point, a location point, or the like.

The virtual scene may be any three-dimensional scene formed by virtual construction, which may be constructed based on a real scene, and thus it can be understood that the embodiment is applied to a real-scene three-dimensional smart city, and meanwhile, the embodiment does not exclude the possibility of being constructed based on a non-real scene.
The entity element in the virtual scene may be any content used for representing an entity structure in a three-dimensional scene, and may also be understood as any entity capable of occupying a certain three-dimensional space in the three-dimensional scene, for example, a building, a vehicle, an animal and plant, a street lamp, a guideboard, a signal lamp, a step, a bridge, a fence, an overhead structure, a road, and the like, where the corresponding entity element is: building elements, vehicle elements, animal and plant elements, street light elements, signpost elements, signal light elements, step elements, bridge elements, fence elements, overhead elements, road elements, and the like.
Fig. 2 is a flowchart illustrating step S11 according to an embodiment of the present invention.
Referring to fig. 2, in one embodiment, step S11 may include:
s111: and determining that an abnormal event occurs according to the data detected by the detection equipment.
The detection device can be understood as any device which exists in a real scene and can detect an event occurring in reality, and the used detection devices can be different according to different events needing to be detected.
The abnormal event can be understood as any event predefined as an abnormal event.
In one embodiment, the detection device may include a camera, for example, at least one of the cameras related to the method according to this embodiment, and the camera may collect a real-time video, and may also be used as a detection device for determining whether an abnormal event occurs.
meanwhile, the embodiment does not exclude the use of a camera which is not used for acquiring the real-time video as the detection equipment, and specifically, a camera of other terminal or computer can be used as the detection equipment. In one example, the camera of the electronic terminal of the inspection staff may be used, the inspection staff may use the electronic terminal to collect the picture or the video at irregular intervals, and then the collected picture or the video may be used to determine whether an abnormal event occurs, if so, the camera of the electronic terminal of the inspection staff may be indicated to be displayed as the target camera to continue the subsequent processing, and other related cameras may also be indicated to be used as the target cameras to continue the subsequent processing.
In addition, the camera serving as the detection device can feed back the identification of the camera so as to determine the target camera, and the camera serving as the detection device can also feed back the position of the camera so as to determine the target camera based on the position.
correspondingly, if the detection device is a camera, the corresponding abnormal event may include at least one of the following:
Identifying a preset first abnormal person from a person in a picture acquired by the camera;
identifying a preset abnormal vehicle from a person in a picture acquired by the camera;
And recognizing the occurrence of the collision accident from the pictures collected by the camera.
The first abnormal person may be any person defined as abnormal, and it is seen whether it is abnormal or not, depending on whether it is defined as abnormal person or not.
The basis of this definition may be deterministic, in one instance the deviant may be a wanted person or a person who has a president, in another instance the person may not necessarily be socially unusual, for example may be a person of a particular age, a particular disease, a particular identity and therefore needs to be particularly noticed, for example may be an elderly person over 80 years, a young child under 10 years, etc.
the basis of the definition may also be uncertain, and in one example, the definition may be freely defined by a human according to historical statistics or a customized configuration, and specifically, for example, some local cities, undesirable sales of cells, misbehaving personnel, and the like may be customized as abnormal personnel.
Meanwhile, whether the person is an abnormal person or not can also be changed according to different requirements, for example, part of the persons who are not allowed to enter or exit through the back door can not be regarded as the abnormal person if the person is shot by the front door camera, and can be regarded as the abnormal person if the person is shot by the back door camera.
In a specific implementation process, if the abnormal event includes that a preset first abnormal person is identified from a person in a picture acquired by the camera, the first abnormal person is identified by comparing a current person image in the acquired picture with a preset abnormal person image of the first abnormal person.
The abnormal vehicles can be, for example, a vehicle with a special photograph, a vehicle with a special size, a vehicle with a special type and the like, wherein the special size can be suitable for a scene with a part of the site with a limited high requirement, and the vehicle with the special type can be suitable for a scene with a part of the site not allowing goods or passenger cars to pass through.
The collision accident can be, for example, a collision between a vehicle and a person, a collision between a vehicle and a vehicle, a collision between a vehicle and a building, and the like, and how to identify the collision accident can be realized through a trained model.
in one embodiment, the detection device may also include an access control device.
The entrance guard equipment can be understood as equipment for verifying the identity when the door is arbitrarily accessed, and the identity can be verified in any mode such as passwords, fingerprints, two-dimensional codes, bar codes, irises and the like.
Correspondingly, if the detection device is an access control device, the corresponding abnormal event may include, for example: and identifying the identity of the person using the access control equipment as a preset second abnormal person. The second abnormal person may be understood by reference to the description of the first abnormal person above.
in one embodiment, the detection device may also include an electronic fence device, a sensor device, etc., and the sensor device may be any device capable of detecting an objective physical world based on physical and chemical principles, such as a temperature sensor, a humidity sensor, an air content sensor, a distance sensor, etc.
Correspondingly, the abnormal event may be, for example, that the quantified data detected by the sensor device exceeds a preset safety threshold.
S114: and determining the target camera according to the occurrence position of the abnormal event and the actual position information corresponding to each camera.
the occurrence location of the abnormal event may be determined, for example, by location information corresponding to the detection device stored in the database, and may be a location of the detection device itself, or a location of a detected object thereof, and for another example, may also be determined by location information reported by the detection device.
in step S114, since the position of the abnormal event is known, the target cameras corresponding to the position of the abnormal event can be compared and determined in combination with different real position information corresponding to different cameras.
After step S114, step S115 may be implemented: and generating the video display indication according to the target camera.
in one embodiment, between step S111 and step S114, the following steps may be further implemented:
S112: and outputting an abnormal prompt to the outside by utilizing the interactive picture.
the exception reminder may be any display content that enables a user to know the occurrence of an exception event through an interactive screen, and may be output externally in the form of a notification or a dialog box, for example.
s113: and acquiring a viewing request, wherein the viewing request is input by a user aiming at the abnormal reminding.
In one example, after the user views the abnormal reminder, corresponding processing may be performed, for example, if the abnormal reminder is output externally in a dialog box, a key capable of triggering generation of the viewing request may be provided in the dialog box, and after the key is pressed, the electronic device may obtain the viewing request.
step S114 may then be understood as being carried out in response to the viewing request.
after step S11, it may include: s12: and acquiring target position information.
the target position information is determined based on the actual position information of the target camera, and may be determined after step S11, or may be stored after being determined in advance before step S11, and further, after the target camera is determined, the stored position information in the corresponding virtual scene may be retrieved.
the real position information may be understood as representing a position of the target camera in a real scene, or a position of a picture acquired by the target camera in the real scene.
In one embodiment, the real position information is two-dimensional real position information in a real scene. In a specific implementation process, the target location information may be determined through a process described later, and the implementation timing may be various.
and determining two-dimensional virtual position information in the virtual scene according to the two-dimensional real position information. For example, two-dimensional coordinates in the real scene, which are two-dimensional real position information, may be projected into the virtual scene, resulting in two-dimensional coordinates in the virtual scene, which are two-dimensional virtual position information.
In one example, the two-dimensional virtual position information may be used as target position information of a camera.
in another example, a specific building element corresponding to the virtual scene may be determined according to the two-dimensional virtual position information; and determining the target position information according to the relative position information of the camera in the specific building corresponding to the specific building element and the position of the specific building element in the virtual scene.
For example, if the position corresponding to the two-dimensional virtual position information is determined as a building element corresponding to a certain building, and if the relative position information indicates that the target camera is located on the roof of the building, the target position information may be determined as the position of the roof of the building element.
In another example, a specific building element corresponding to the virtual scene may be determined according to the two-dimensional virtual position information, and then the position represented by the target position information is determined as the position of the specific building element in the virtual scene, that is, it is not necessary to distinguish which part of the building element is in.
In another example, a specific building may be determined according to the two-dimensional real position information, then the position information of the specific building element corresponding to the specific building in the virtual scene is determined, and then the target position information is determined according to the relative position information of the target camera in the specific building corresponding to the specific building element and the position information of the specific building element in the virtual scene.
therefore, through the above process, a three-dimensional position can be determined based on two-dimensional position information, so that in a virtual scene, a real-time video can be displayed at a specific three-dimensional position, and the real-time video can be more accurately matched with the position corresponding to the real-time video.
After step S12, it may include:
S13: and accessing the real-time video, and displaying the real-time video in the interactive picture of the virtual scene according to the position indicated by the target position information.
In one embodiment, the process of accessing the real-time video may access the video real-time video, for example, to a video management system of a security company.
wherein, according to the position indicated by the target position information, the real-time video is displayed, which can be understood as: the position of the final real-time video is associated with the position indicated by the target position information, which may for example be in its vicinity, but also for example a certain point, a certain line, a certain area of the video window overlapping, being close to, etc. the position indicated by the target position information.
FIG. 3 is a schematic interface diagram of a video display according to an embodiment of the invention.
Referring to fig. 3, the target location information can be understood as the doorway of the north door 1, and further, when displaying the real-time video, the lower line of the window of the real-time video can be set to be located at the upper side of the north door 1, so that it can be easily known that the video corresponds to the location.
In the specific implementation process, the accessed real-time video can be one path or multiple paths. The method comprises the condition of simultaneously accessing different real-time videos of different target position information, the condition of accessing a plurality of real-time videos of the same target position information, the condition of accessing one real-time video of one target position information, and the condition of accessing one real-time video corresponding to a plurality of target position information.
if the same target position information corresponds to a plurality of real-time videos which need to be accessed, the windows of the real-time videos can be uniformly and/or symmetrically distributed relative to the target position information.
In one embodiment, when the real-time video is displayed, the associated description information of the abnormal event may be displayed in the interactive screen.
The association description information may be any information associated with the abnormal event, for example, if the abnormal event is related to an abnormal person, the association description information may be description information of the abnormal person; for example, if the abnormal event is related to an abnormal vehicle, the associated description information may be description information of the abnormal vehicle; in addition, the associated description information may also have location information of the abnormal event.
Therefore, the video display method in the virtual scene provided by the embodiment can access the real-time video after acquiring the video display instruction, and display the real-time video in the interactive picture of the virtual scene. Furthermore, the embodiment can be convenient for the user to carry out real-time and effective monitoring on the object monitored by the camera through displaying the real-time video.
