Problems solved by technology

Although with the development of storage technology, large-capacity storage devices can better solve this problem, but in view of the image data itself has the defect of occupying a lot of bytes, even if a large-capacity storage device is used at any cost, it is still a problem. Difficulty saving all video images over a long period of time
[0004] In the existing technology, when performing video content retrieval and review, 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 playba

Embodiment Construction

[0054] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention.

[0055] In a video system for shooting by a still camera, it is common that the obtained and stored video images do not change significantly for a long time. figure 1 An embodiment of a video analysis and storage system is shown, which embodiment includes a detection module 110, a preservation module 120 and a storage module 130, wherein:

[0056] The detection module 110 detects the motion of the video image, and judges whether the video image contains an object in motion, that is, a moving target, and if so, further performs target detection, and notifies the preservation module 120, such as detecting that it is in motion The state of the human body or car, etc., tha...

Abstract

The invention discloses a video analysis and storage method, a system and a video detection method and a system, respectively saving the storage space of the video image and increasing the efficiency of the video search, wherein the analysis and storage method and the system analyze the video image and store the motion segment containing the motion target, while the video detection method and the system analyze the video image and store motion segment containing the motion target, and the related motion target information and the motion segment information, search the stored motion segment according to the information and the index term input by the users. The invention can be widely applied in the video processing system, particularly the video monitoring system.

Description

technical field [0001] The invention relates to image processing technology, in particular to a video analysis and storage method and system, and a video retrieval method and system. Background technique [0002] The existing video surveillance system stores video images in a way that generally the video recorded by the camera is stored in a database in real time and completely. For general video surveillance application scenarios, such as warehouses, factories, etc., during some periods of time such as night, the monitored scenes rarely change, and few moving objects enter these monitored spaces. For an application scenario where a static camera is used for monitoring, the scene picture is generally static, that is to say, the image will remain the same picture for a long time without obvious changes. [0003] The existing technology saves the video images at every moment to storage devices such as hard disks and video tapes in real time, so as to prepare for applications ...
