Example Embodiment

[0031] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings.

[0032] In the present invention, the video summary is independently generated by the network storage device, and there is no need to set up another PC to assist it, thus simplifying the information interaction and saving the cost; and the network storage device only stores the moving target information, and the moving target information includes the moving target information. The coordinate position of the target in the video image, the video frame number and time point of the video image are greatly reduced compared to a large number of moving target images.

[0033] see image 3 , is a schematic flow chart of the method for generating a video summary based on a moving target of the present invention, which includes the following steps:

Abstract

The invention discloses a video abstraction generating method, system and network storage equipment based moving on objects. The method includes separating background images and moving objects in the video bitstream, and generating and storing moving object information; receiving a video abstraction generating request, extracting the stored moving object information, and dividing the moving object information according to set time slots; stacking and sequencing the groups of moving object information according to corresponded time sequence, and acquiring the sequenced abstraction track information; reading the moving object information of the abstraction track information according to the sequences, extracting corresponded video images from the stored video bitstream according to video frame numbers of the moving object information, capturing the moving object images from the extracted video images according to coordinate locations of the moving object information, and stacking the captured moving object images with the background images. By the aid of the method, the cost can be saved, and the storage capacity for generating the video abstraction can be decreased.

Description

technical field [0001] The invention relates to multimedia video processing technology, in particular to a method, system and network storage device for generating video summaries based on moving objects. Background technique [0002] In the video monitoring solution, the video monitoring equipment collects video of the monitoring scene, and sends the acquired video code stream to the network storage device for storage. The application scenarios of video surveillance include public security, justice, important meeting records, etc. [0003] Later, when the video information of the monitoring scene needs to be viewed, the stored video data can be extracted to obtain video information about a specified moving target. In recent years, with the continuous development of storage technology in the surveillance industry, a large amount of surveillance video data has emerged, and the current network storage device only saves the video data. If you want to find the content related t...
