Embodiment 1

[0028] figure 1 It is an implementation flowchart of the video file search method provided by the embodiment of the present invention, and is described in detail as follows:

[0029] In step S101, in the process of video recording, detect whether an external event is received;

[0030] In step S102, when the external event is received, it is judged whether the external event is in a pre-configured external event list;

[0031] Wherein, before step S102, an external event list is configured.

[0032] It should be noted that configuring the external event list may also be performed before step S101, and there is no limitation here.

[0033] Wherein, the external event list includes all external events defined by the user, and the external events include but are not limited to detection of flame events, detection of thick smoke events, detection of personnel car accident action events, and detection of item loss events.

[0034] In step S103, when the external event is in the ...

Embodiment 2

[0039] figure 2 It is an implementation flowchart of step S103 of the video file search method provided by the embodiment of the present invention, and is described in detail as follows:

[0040] In step S201, when the external event is in the external event list, record the trigger time and end time of the external event;

[0041] In step S202, a video file is generated according to the external event packaging, and the video file identifier of the video file is recorded;

[0042] Wherein, when the video file is packaged and generated according to the external event, the video file identifier is generated, and the video file identifier is the unique data identifier of the video file, and there is a one-to-one correspondence relationship between the two.

[0043] In step S203, a video file search information table is generated using a preset data structure according to the trigger time and end time of the external event and the video file identifier.

[0044] The preset dat...

Embodiment 3

[0047] image 3 It is the implementation flowchart of step S104 of the video file search method provided by the embodiment of the present invention, and is described in detail as follows:

[0048] In step S301, acquire the external event to be searched input by the user;

[0049] In step S302, in the video file search information table, call the video file identification corresponding to the external event to be searched;

[0050] In step S303, the video file is searched according to the video file identifier.

[0051] After searching the video file, the video file can be retrieved, and the video image can be located in the video file according to the trigger time of the external event, and the video image can be played frame by frame after positioning.

[0052] In the embodiment of the present invention, the video file is searched according to the video file identifier, which is convenient for searching the speed of the video file.

Abstract

The invention is suitable for the technical field of video file searching, and provides a searching method and device for video files. The searching method for the video files includes the steps of detecting whether an external event is received or not in the video recording process; when the external event is received, judging whether the external event exists in a pre-configured external event list or not; when the external event exists in the pre-configured external event list, generating a video file searching information table according to the triggering time and the end time of the external event and video file identification generated according to the external event; searching the video file searching information table for the video files. By means of the searching method and device for the video files, the conditions that when a video monitoring system is searched for the large number of video files in different types, the searching speed is low, the searching step is complex, and excessively-many resources of the video monitoring system are occupied are avoided, the video file searching convenience is improved, and the video file searching accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of video file search, in particular to a video file search method and device. Background technique [0002] In the application of video surveillance system, video search is an essential function, that is, according to the specified search conditions, the video files that meet the requirements are searched in all the video file collections. Recording files include ordinary recording files, recording files containing special marks (such as alarm recording files) and so on. Users can view the required video files through the video search function. [0003] However, the existing video file search method, when searching a large number of different types of video files in the video surveillance system, the search speed is slow, the search steps are complicated, and at the same time occupy too many system resources, affecting other functions of the system, and cannot meet the needs of today's high-definition , a ...
