Embodiment Construction

[0047] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific examples, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention .

[0048] Such as figure 1 As shown, a video data linear storage method provided by an embodiment of the present invention includes the following steps:

[0049] S10. Obtain video data and store it in a conventional data area;

[0050] S20. When it is detected that the free storage space in the regular data area is close to the preset sliding window size, extract the key frame data in at least one piece of video data stored in the oldest video data area in the regular data area, and release the storage space occupied by these video data ;

[0051] S30. Store the key frame data in a resident data area.

[0052] In a preferred implementation manner, ...

Abstract

The invention discloses a linear storage method, device and terminal for video data. The method comprises the steps of acquiring video data, and storing the video data into a conventional data region; extracting key frame data in at least one section of video data stored for the longest time in the conventional data region when monitoring that an idle storage space in the conventional data region approaches to a preset sliding window in size, and releasing the storage space occupied by the video data; storing the key frame data into a resident data region. By using the linear storage method, the possibility that historical data is covered is delayed as much as possible, the scheduling policy is relatively balanced, and the requirements of a user for integrity, long-term storage and storage efficiency of the video data are met.

Description

technical field [0001] The present invention relates to the technical field of monitoring, in particular, to a video data linear storage method, device and terminal that can extend the recording time of video data and avoid fragmentation of storage media. The present invention can be applied to vehicle-mounted monitoring systems. Background technique [0002] At present, with the continuous improvement of people's security awareness, campus security, home security, and public facility security have received more and more attention from the society. High-quality image data provides convenience for criminal investigation and ensures the safety of people's lives and property. [0003] With the advent of the digital video era, the image quality is getting clearer and the data volume is getting bigger and bigger. Therefore, in terms of storage, people hope to store key information for as long as possible with a certain storage medium capacity. , and the video data access efficie...
