Problems solved by technology
In this way, only one warning image is presented on the warning terminal, and the information presented by the warning terminal is limited.
In addition, if a complete recording and analysis alarm video is provided for the alarm terminal, it is necessary to analyze and process each frame of the real-time video, and to identify the alarm condition, it is necessary to increase the frame extraction frequency and analyze each frame of the real-time video then the consumption of image processing resources will increase
It can be seen that currently, if real-time alarm video is provided for alarm terminals, it will impose a heavy burden on image processing resources and network resources, especially when multiple collection terminals alarm at the same time, the analysis service will be overloaded instantly, resulting in failure to request real-time video , then the recording also fails
In severe cases, it may affect the business being analyzed, and the user experience is relatively poor

Embodiment Construction
[0060] The technical content of the present disclosure will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0061] In order to enable those skilled in the art to better understand the present disclosure, some technical terms involved in the present disclosure are explained as follows:
[0062] Alarm terminal: a terminal used for alarm presentation, for example, it can display alarm video, alarm image, etc. The alarm terminal can be a computer, mobile phone, tablet computer, PDA (Personal Digital Assistant) handheld terminal, video phone, etc.
[0063] Acquisition terminal: the terminal that completes the video image acquisition work to provide video streams to the video analysis service (which can run on the video analysis service module, and the video analysis service module can be set at an external server, computer or the acquisition terminal.), the acquisition terminal It can be an image acquisition device, suc...

The invention relates to an alarm video acquisition method and device. The method comprises the following steps: firstly, performing video analysis on an original video stream, generating alarm starting information when a preset event occurs, and sending the alarm starting information to an alarm terminal, so that the alarm terminal records an alarm starting moment; when it is determined that thepreset event is ended, generating alarm release information and sending the alarm release information to the alarm terminal so that the alarm terminal records an alarm ending moment; receiving a to-be-analyzed alarm video sent by the alarm terminal, wherein the to-be-analyzed alarm video is intercepted from an original video stream of an acquisition terminal by the alarm terminal according to thealarm starting moment and the alarm ending moment; and identifying the to-be-analyzed alarm video according to the local processing resources to form a marked alarm video. The device does not need tosend the video stream to the alarm terminal in real time to cause overlarge load of network resources and processing resources, can fully utilize the local processing resources of a video analysis module, provides the alarm video for the alarm terminal, and guarantees the complete recording of the alarm video.
Description
technical field [0001] The present disclosure relates to a method for obtaining a warning video, and also relates to a corresponding device for obtaining a warning video, belonging to the technical field of video analysis. Background technique [0002] In some security, monitoring and other scenarios, it is generally necessary to perform video analysis on the video images collected by the acquisition terminal, so as to effectively monitor the relevant scenes and generate alarm records when monitoring abnormalities. [0003] In order to enable the alarm terminal in the background to know the monitoring situation in time, when an abnormality is detected in the monitoring, the alarm record can be pushed to the alarm terminal for display. In general, due to limited network resources, the same alarm terminal may need to receive alarm records from a large number of collection terminals, so the alarm record generally only contains one alarm image. , what is collected is a warning ...
