Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0029] See figure 1 , this embodiment provides a multi-layer data structure formed by four layers of intelligent metadata stream, intelligent metadata, metadata components, and attribute information in order to achieve a structured description for target information in video surveillance, as follows :

[0030] 1) Intelligent metadata flow

[0031] The smart metadata stream may be generated by the monitoring device and contain at least one smart metadata.

[0032] Wherein, each smart metadata in the smart metadata stream may correspond to an object group (ObjectGroup), therefore, the smart metadata stream represents a data stream format with the object group as the basic unit. Alternatively, it can also be considered that the smart metadata flow repre...

Abstract

The invention discloses a method and device for achieving the structural description in a video monitoring system. According to the invention, a multilayer data structure is employed, wherein the multilayer data structure consists of an intelligent metadata flow, intelligent metadata, a metadata module, and attribute information, thereby achieving the structural description through the multilayer data structure. Based on the structural description through the multilayer data structure, the method can find a specific target in a large number of video files more easily and quickly, so as to carry out the intelligent applications, such as video search and positioning, and video abstract display. Moreover, the attribute information of each metadata module in the multilayer data structure can comprise one or any combination of time and space attributes, motion type attributes, detection type attributes and semi-structural attributes, thereby enabling the structural description achieved through the method to be more flexible and to be easier to expand.

Description

technical field [0001] The invention relates to video monitoring technology, in particular to a method for implementing structured description in a video monitoring system and a device for implementing structured description in a video monitoring system. Background technique [0002] The video surveillance system usually includes such monitoring equipment as a network camera (IPCamera, IPC), a network video recorder (NetworkVideoRecorder, NVR), a digital video recorder (DigitalVideoRecorder, DVR), etc., which are located at the monitoring front end, and are used to provide information to the back-end application platform. Video surveillance files. [0003] However, with the continuous improvement of the resolution supported by the monitoring equipment, the storage capacity required for the monitoring files stored on the application platform is getting larger and larger. It will consume a lot of time and resources to find a specific target in a large number of surveillance f...
