Problems solved by technology
[0003] However, with the continuous expansion of the monitoring system, the number of monitoring channels such as IPC (Internet Protocol Camera, network camera) channels and analog channels under a monitoring system is increasing, resulting in an increasing amount of video data that electronic equipment needs to store. The larger the size, the electronic device must have enough storage space, which increases the hardware cost of the electronic device for storing video data

The embodiment of the invention provides a video data storage method and device. The method comprises the following steps: sequentially acquiring the video data of each channel according to a pollingmode, performing target identification on the video data of the channel after acquiring the video data of one channel each time, identifying a specified target in the video data of the channel, and storing the video data of the channel if the specified target exists in the video data of the channel; carrying out target identification on video data collected by one channel, and judging whether a specified target exists in the video data of the channel or not; if so, storing the video data of the channel; performing the operation on each channel in a polling mode. According to the method, that the electronic equipment stores the video data which is collected by all channels and has the specified target is ensured, the data size of the stored video data is smaller than that stored in a traditional mode, needed storage space is smaller than that needed in the traditional mode, and hardware cost of the electronic equipment storing the video data is saved.
Description
technical field [0001] The invention relates to the technical field of monitoring, in particular to a video data storage method and device. Background technique [0002] In the monitoring system, after the video acquisition equipment collects the video data, it needs to send the video data to electronic devices such as DVR (Digital Video Recorder, hard disk video recorder), NVR (Network Video Recorder, network hard disk video recorder), central storage device, etc. storage. In the current video data storage method, the electronic device directly stores the video data after receiving the video data. [0003] However, with the continuous expansion of the monitoring system, the number of monitoring channels such as IPC (Internet Protocol Camera, network camera) channels and analog channels under a monitoring system is increasing, resulting in an increasing amount of video data that electronic equipment needs to store. The larger the size, the electronic device must have suffi...
