Problems solved by technology

[0005] The disadvantage of a video analysis and retrieval method in the above-mentioned prior art is that in this method, the definition and realization of the analysis attributes, the configuration and realization of the retrieval logic, and the customization of the display mode of the retrieval results all require experts to formulate corresponding logic rules. Afterwards, it is time-consuming and labor-intensive for specific custom development by developers, and it is not easy to quickly put it into other industries or other application types

Embodiment 1

[0041] The embodiment of the present invention provides a method for retrieving media data based on a data model, so as to meet the rapid configuration requirements of various industries for the rapid retrieval of massive videos and other media contents. The processing flow of this method is as follows figure 1 As shown, the following processing steps are included:

[0042] Step S110, configure the data model of the media data through the data model configurator.

[0043] In the embodiment of the present invention, the data model is configured through the data model configurator. The data model configurator is a tool that realizes independent packaging and is presented in the form of an application program. The data model configurator is used to create, modify and activate a data model for media resource management. The operation of configuring the data model can be completed before or after the collection of media data, as long as the required data model is activated accord...

Embodiment 2

[0075] This embodiment provides a device for retrieving media data based on a data model, and its specific implementation structure is as follows figure 2 As shown, it can specifically include the following modules:

[0076] The data model configuration model 21 is used to configure the data model of media data through the data model configurator, and the data model includes language elements, object class elements, main data class elements, attribute group elements, attribute elements, association elements, and metadata forms element, search form element, and result list element.

[0077] Metadata establishment module 22, for utilizing the metadata form in described data model to establish the metadata of media data;

[0078] The search result acquisition module 23 is used to search in the media database using the search form in the data model to obtain search results;

[0079] The search result display module 24 is configured to display the search result by using the resu...

Abstract

The embodiment of the invention discloses a method and device for searching media data based on a data model. The method mainly comprises the steps of allocating the data model of the media data by a data model allocator, establishing metadata of the media data by using a metadata form in the data model, searching in a media database by using a searching form in the data model to obtain searching results, and displaying the searching results by using a result list in the data model. By adopting the method and the device disclosed by the embodiment, definition and implementation of analytic attribute of the media data can be rapidly implemented, the allocation and implementation of searching logic can be implemented, the customization of displaying modes of the searching results can be implemented; the shortcomings that the traditional mode that specialists formulate corresponding logic rules, and then developers develop corresponding logic strategies in a customized way is long in time, heavy in task, poor in portability can be overcome; the analysis and searching efficiency of the media data are improved.

Description

technical field [0001] The invention relates to the technical field of business system management, in particular to a method and device for retrieving media data based on a data model. Background technique [0002] Video surveillance has been widely used in many fields such as safe cities and intelligent transportation. The video surveillance market is growing every year, and front-end cameras are constantly being laid. At the same time, massive video data, massive media data, and Applications have been gradually put on the agenda. In order to further meet the business needs of related industries and effectively use massive video data, it is necessary to analyze and retrieve video data. [0003] In the process of analyzing and retrieving video data, it is necessary to perform video analysis on these massive video data to obtain the relevant attributes of the video, and complete the association between attributes and video data, so as to realize the rapid retrieval of massive...
