[0027] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0028] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0029] Figure 1 A flow chart of a detection screen switching method is provided for an embodiment of the present invention. This embodiment can be applied to the situation where detection screens corresponding to different detection scenes are quickly switched and displayed when the detection scene is switched. The method can be executed by a detection screen switching device. The detection screen switching device can be implemented in the form of hardware and / or software. The detection screen switching device can be configured in any electronic device with network communication function.

[0030] like Figure 1 As shown, the method for detecting screen switching in this embodiment may include the following process:

[0031] S110: Perform video stream negotiation on a shooting device corresponding to a next detection scene.

[0032] S120. After completing the negotiation of the video stream of the shooting device corresponding to the next detection scene, execute the switching operation of the next detection screen window corresponding to the next detection scene. The switching operation of the next detection screen window includes executing the following actions in sequence: deactivating the video stream of the shooting device corresponding to the current detection scene, closing the current detection screen window corresponding to the current detection scene, and opening the next detection screen window.

[0033] As the number of inspection targets continues to increase, more shooting equipment (such as gun cameras, hemispherical cameras, integrated cameras, infrared day and night cameras, high-speed ball cameras, network cameras, etc.) needs to be deployed for all-round coverage inspection. At the same time, in order to better manage the inspection process of each shooting device, the inspection images of batch shooting devices need to be presented in the same display screen. However, due to the large number of deployed shooting devices, it takes a lot of manpower and material resources to realize simultaneous presentation for inspection, which derives the concept of inspection scene planning.

[0034] See also Figure 2, the detection scene plan can refer to multiple detection scenes switching at set time intervals, and each detection scene is used to display the detection screen of the camera associated with the detection scene. The switching time interval between the detection scenes corresponding to detection scene 1 and detection scene 2 is set to 60s, and the detection scene is switched every 60s through the timer, and the camera associated with the detection scene is stored in the cache. Figure 3 As shown, the shooting devices associated with detection scene one include camera 1, camera 2, ..., camera 9, and the shooting devices associated with detection scene two include camera 1, camera 2, ..., camera 16.

[0035] See also Figure 4 , take detection scene 1 as the current detection scene and detection scene 2 as the next detection scene as an example, when starting to switch from the current detection scene to the next detection scene, if the video stream negotiation with the shooting device associated with the current detection scene in the current detection scene is closed in sequence, all the detection screen windows corresponding to the current detection scene are closed, and then all the detection screen windows corresponding to the next detection scene are opened, and the video stream negotiation with the shooting device associated with the next detection scene in the next detection scene is established. In the above detection scene switching process, the switching time determines the time when the picture is still during the detection scene switching process, which will cause the picture to freeze or flash black, and the longer the detection scene switching time is, the worse the visual effect is.

[0036] See also Figure 5 , since the video stream negotiation with the shooting device corresponding to the detection scene is the most time-consuming process during the detection scene switching process, the present application solution negotiates the video stream of the shooting device corresponding to the next detection scene in advance when switching from the current detection scene to the next detection scene, and still uses the video stream of the shooting device corresponding to the current detection scene to display the detection screen during the negotiation. After closing the video stream negotiation of the shooting device associated with the current detection scene in the current detection scene in turn, closing all the detection screen windows corresponding to the current detection scene, and then opening all the detection screen windows corresponding to the next detection scene, since the video stream negotiation with the shooting device corresponding to the next detection scene has been performed in advance, the video stream of the shooting device corresponding to the next detection scene can be quickly provided, so that the detection screen can be quickly switched and displayed as the detection scene switches.

[0037] S130: Use the next detection picture window to process the video stream of the shooting device corresponding to the next detection scene.

[0038] As an optional but non-limiting implementation, performing video stream negotiation on a shooting device corresponding to the next detection scene includes the following steps:

[0039] When the detected duration of the current detection scene reaches a first reference duration, video stream negotiation is performed on the shooting device corresponding to the next detection scene, and the first reference duration is less than a pre-configured detection scene switching time interval between the current detection scene and the next detection scene.

[0040] Although the efficiency of switching detection scenes can be improved by negotiating the video stream of the shooting device corresponding to the next detection scene in advance, negotiating the video stream of the shooting device corresponding to the next detection scene in advance will occupy more network negotiation resources. Since the number of network links is limited by the system, it is necessary to consider how to use network negotiation resources efficiently while achieving fast switching of detection scenes.

[0041] To this end, in the application of the detection scene plan, the present application sets a first reference duration according to the detection scene switching time interval between the current detection scene and the next detection scene, and configures the first reference duration to be less than the pre-configured detection scene switching time interval between the current detection scene and the next detection scene. When switching to the current detection scene, the detected duration of the current detection scene will be timed, and when the detected duration of the current detection scene reaches the first reference duration, the video stream negotiation for the shooting device corresponding to the next detection scene will be started, so that the video stream negotiation can be performed by occupying part of the network connection resources in the current detection scene, and the video stream of the shooting device corresponding to the next detection scene is negotiated in advance in the current detection scene, so that the detection screen can be quickly switched to display the detection screen after the detection scene is switched.

[0042] Optionally, the first reference duration can enable video stream negotiation for a shooting device corresponding to a next detection scene to be completed no later than before switching from a current detection scene to a next detection scene is initiated.

[0043] Optionally, the completion time of the video stream negotiation for the shooting device corresponding to the next detection scene is no later than the start time of switching from the current detection scene to the next detection scene.

[0044] As an optional but non-limiting implementation method, the first reference duration is determined based on a pre-configured detection scene switching time interval between the current detection scene and the next detection scene, the number of video streams of the shooting device corresponding to the next detection scene, and the time consumed for video stream negotiation with each shooting device corresponding to the next detection scene.

[0045] Since the video stream of the shooting device corresponding to the next detection scene will be negotiated in advance in the current detection scene, the network connection resources of the current detection scene will be occupied to a certain extent, affecting the video stream transmission of the current detection scene. For this reason, this application will fully consider the number of video streams of the shooting device corresponding to the next detection scene and the time consumed for the video stream negotiation of each shooting device corresponding to the next detection scene in the application of the detection scene plan, so that the start time of the video stream negotiation of the shooting device corresponding to the next detection scene can be dynamically allocated according to the minimum time consumed for the video stream negotiation of the shooting device corresponding to the next detection scene, and the video stream negotiation is performed according to the dynamically allocated time setting, so as to reduce the image of the video stream transmission corresponding to the current detection scene as much as possible. Due to the limited network link resources of the system, the above method can not only effectively improve the scene switching effect, but also improve the utilization rate of network connection resources.

[0046] As an optional but non-limiting implementation, before performing video stream negotiation on a shooting device corresponding to the next detection scene, the following steps are also included:

[0047] When switching to the current detection scene and starting detection, the first timer is started, and the first timer is used to detect whether the detection time of the current detection scene reaches the first reference time.

[0048] See also Figure 5 The video stream negotiation time M of the shooting device corresponding to the next detection scene can be determined in advance based on the number of video streams of the shooting device corresponding to the next detection scene and the time consumed for video stream negotiation with each shooting device corresponding to the next detection scene. Then, the difference between the detection scene switching time interval between the current detection scene and the next detection scene based on the pre-configured detection scene and the video stream negotiation time M of the shooting device corresponding to the next detection scene is used as the first reference duration.

[0049] See also Figure 5 , configure and start the first timer a when starting to switch to the current detection scene, the timing duration is the first reference duration, and the first timer is used to detect whether the detected duration of the current detection scene reaches the first reference duration, so that when the first timer a detects that the detected duration of the current detection scene reaches the first reference duration, start video stream negotiation for the shooting device corresponding to the next detection scene.

[0050] As an optional but non-limiting implementation, executing the switching operation of the next detection scene corresponding to the next detection picture window includes the following steps:

[0051] When the startup duration of the video stream negotiation for the shooting device corresponding to the next detection scene reaches the second reference duration, the switching operation of the next detection screen window corresponding to the next detection scene is executed, and the first reference duration plus the second reference duration is equal to the pre-configured detection scene switching time interval between the current detection scene and the next detection scene.

[0052] The above switching process solution saves the time for negotiating the video stream of the shooting device corresponding to the next detection scene, improves the speed of displaying the detection screen of the next detection scene, and thus improves the efficiency of switching the detection scene. By dynamically allocating the time for pre-collecting the scene network stream, the occupation of network negotiation resources is reduced, and the utilization rate of network resources is improved. By improving the switching efficiency of the video source in the scene, the overall effect of scene switching is improved, and the user's visual experience is improved, the network pre-collecting stream time is dynamically allocated, the network cache occupation is reduced, and the resource utilization rate is improved.

[0053] As an optional but non-limiting implementation, before executing the switching operation of the next detection scene corresponding to the next detection screen window, the following steps are also included:

[0054] When starting to switch the video stream negotiation for the shooting device corresponding to the next detection scene, the second timer is started, and the second timer is used to detect whether the started duration of the video stream negotiation for the shooting device corresponding to the next detection scene reaches the second reference duration.

[0055] See also Figure 5 When starting to switch the video stream negotiation for the shooting device corresponding to the next detection scene, configure and start the second timer b, the timing duration is the second reference duration, the second reference duration is the video stream negotiation time M of the shooting device corresponding to the next detection scene, and the second timer is used to detect whether the started duration of the video stream negotiation for the shooting device corresponding to the next detection scene reaches the second reference duration, and when the second reference duration is reached, the switching operation of the next detection screen window corresponding to the next detection scene is performed.

[0056] The above optional solution is used to pre-cache the network negotiation of the next scene, saving the time spent on network negotiation during the switching process, thereby improving the efficiency of scene switching and reducing visual differences. Due to the limited network link resources, a timer mechanism is used to dynamically allocate the cache network resource time according to the number of network flows in the next scene, thereby reducing the occupation of network link resources and improving the utilization of network link resources.

[0057] The technical solution of the embodiment of the present invention is to negotiate the video stream of the shooting device corresponding to the next detection scene. After completing the video stream negotiation of the shooting device corresponding to the next detection scene, the switching operation of the next detection screen window corresponding to the next detection scene is executed. The switching operation of the next detection screen window includes executing the following actions in sequence: deactivating the video stream of the shooting device corresponding to the current detection scene, closing the current detection screen window corresponding to the current detection scene, and opening the next detection screen window, and then using the next detection screen window to process the video stream of the shooting device corresponding to the next detection scene. By occupying more optimal network link resources, completing network negotiation with the camera in advance to receive the video stream in advance, and improving the switching efficiency of the video stream in the detection scene, the detection scene switching can be quickly output, saving the time consumed by the network negotiation during the scene switching process, and improving the scene switching output speed.

This embodiment can be applied to the situation where detection screens corresponding to different detection scenes are quickly switched and displayed when the detection scene is switched. The detection screen switching device can be implemented in the form of hardware and / or software, and the detection screen switching device can be configured in any electronic device with network communication function.

[0060] Negotiation module 610, used to negotiate the video stream of the shooting device corresponding to the next detection scene;

[0062] The processing module 630 is used to process the video stream of the shooting device corresponding to the next detection scene using the next detection picture window.

[0063] Based on the above embodiment, optionally, performing video stream negotiation on a shooting device corresponding to a next detection scene includes:

[0064] When the detected duration of the current detection scene reaches a first reference duration, video stream negotiation is performed on a shooting device corresponding to a next detection scene, and the first reference duration is less than a pre-configured detection scene switching time interval between the current detection scene and the next detection scene.

[0071] Based on the above embodiment, optionally, the first reference duration can enable the video stream negotiation for the shooting device corresponding to the next detection scene to be completed no later than before the switching from the current detection scene to the next detection scene is started.

[0072] Based on the above embodiment, optionally, the first reference duration is determined based on a pre-configured detection scene switching time interval between the current detection scene and the next detection scene, the number of video streams of the shooting device corresponding to the next detection scene, and the time consumed for video stream negotiation with each shooting device corresponding to the next detection scene.

[0073] The technical solution of the embodiment of the present invention is to negotiate the video stream of the shooting device corresponding to the next detection scene.
