Video recording method, device, network camera and storage medium

Abstract

The invention discloses a video recording method, device, network camera and storage medium. The present invention compares the relative time stamp of the current image uploaded by the image sensor with the recording time stamp of the current recording frame, then determines the image to be recorded corresponding to the current recording frame according to the comparison result, and finally performs video recording according to the image to be recorded recording. It can be seen that, through the technical solution of the present invention, video recording is not performed directly according to the image reported by the image sensor, but is determined according to the comparison result between the relative time stamp of the current image uploaded by the image sensor and the recording time stamp of the current recording frame. The image to be recorded corresponding to the current recording frame, and then video recording is performed according to the image to be recorded, so that the relative time stamp of the image to be recorded can be closer to the recording time stamp of the current recording frame, so that the frame rate of the recorded video is stable, The smoothness of video playback is guaranteed.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a video recording method, device, network camera and storage medium. Background technique [0002] The main function of the network camera (IP Camera) is to monitor the scene in real time, obtain real-time images through the image sensor of the network camera, and use the application program in the control terminal of the network camera to choose to live broadcast the scene in real time or record the video and upload it to the server. For some network cameras with complex functions, in addition to acquiring images, it is also necessary to analyze the content of the images, such as acquiring moving objects in the current scene or detected actions. [0003] The analysis process is generally time-consuming, resulting in uneven time for the image sensor to report the image to the control terminal. At the same time, in the process of long-term operation, due to the system ins...
