Embodiment Construction

[0042] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0043] The basic idea of ​​the present invention is to shorten the online query time with the storage space of the computer through the offline indexing process. Through simple configuration file information, the relationship between the characteristic data table and the index data table is mapped, thereby establishing the index of the characteristic data, and using the characteristic data ID value to ...

Abstract

The invention discloses a video feature data query method based on HBase and Solr, and the method comprises the following steps that a server receives a feature data query request from a user, and carries out the retrieval in an index storage set according to the feature data query request, so as to obtain a plurality of feature data ID values; the server retrieves a corresponding feature data setin an HBase database according to the plurality of feature data ID values obtained in the step 1, and returns the feature data set to the user. According to the invention, the configuration file is established; the feature data and the index are associated by using the feature data ID value, so that the data retrieval efficiency and accuracy are improved, and the technical problem that the massive feature data cannot be accurately queried due to the fact that the feature data storage time is prolonged and the feature data volume is increased in an existing video monitoring system can be solved.

Description

Technical field [0001] The invention belongs to the technical field of big data storage and query, and more specifically, relates to a method and system for querying video feature data based on HBase and Solr. Background technique [0002] With the advancement of Internet technology, surveillance systems and computer vision, surveillance systems have gradually developed in the direction of intelligent surveillance systems. In recent years, my country has realized a metropolitan area video surveillance system through the construction of Safe City and Skynet Project. [0003] At present, with the continuous expansion of the construction scale of the video surveillance system, the characteristic data of the converted videos and pictures collected by the video surveillance system will be stored for longer and longer, and the accumulation of characteristic data will become larger and larger. How to deal with these massive amounts Accurate data query has become a technical problem. Sum...
