Embodiment Construction

[0043] The basic idea of ​​the present invention is: to detect dangerous events on each frame of video images, and record the description information of dangerous events; when the user wants to retrieve video images with dangerous The event description information matches, and if it is matched, the video image with the dangerous event is found according to the dangerous event description information, and the video image is displayed to the user.

[0044] The present invention can also store only video images of dangerous events, so as to save storage space.

[0045] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0046] figure 1 The flow chart of detecting dangerous events in video images provided by the embodiment of the present invention, such as figure 1 As shown, the specific steps are as follows:

[0047] Step 100: Pre-set dangerous event triggering rules.

[0048] Step 101: Th...

Abstract

The invention discloses a method for searching a video, a system therefor and a device therefor as well as a video storing method and a system thereof. The method for searching the video comprises the following steps: performing motion detecting and tracking on a video sequence; if detecting a risk event existing in a video image, recording descriptive information of the risk event, wherein the descriptive information comprises at least an image identifier with the risk event; when searching the video image with the risk event, receiving a searching condition; matching the searching condition and the recorded descriptive information of the risk event, if matched, obtaining the video image from a video storing device according to the image identifier in the descriptive information of the risk event, and displaying the video image to a user. The invention improves the video searching efficiency. Furthermore, the invention only stores the video image with the risk event, thereby saving the storing space.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a video retrieval method, system, equipment, and video storage method and system. Background technique [0002] With the rapid development of multimedia technology and network technology, video surveillance technology has been widely used in various fields of security. It has become an urgent need to organize, express, manage, query and retrieve these massive surveillance video data containing a large amount of unstructured information. Therefore, intelligent video retrieval technology for surveillance video has become one of the important research topics in the security field in recent years. [0003] In the existing technology, when performing video content review and retrieval, manual review is often used, that is, the saved video is played and the video is manually judged. This review method is inefficient and prone to omissions. When manually reviewing, the video ...
