Embodiment Construction

[0048] In order to clearly illustrate the distributed retrieval method of the present invention, a specific description will be given below in conjunction with the accompanying drawings.

[0049] figure 1It is an architectural diagram of a Hadoop-based distributed retrieval method for transmission line monitoring video, supported by HDFS and Map / Reduce modules of the Hadoop platform, supplemented by OpenCV (an open source computer vision library) vision library and key frame extraction Algorithm, massive original transmission line video data is converted into corresponding key frames, and the final retrieval results are displayed to users on the web interface through the key frame index. It mainly includes three parts: the storage of massive video data, the extraction of key frames and the index of key frames, and finally display the retrieval results on the web interface. The HDFS part in the architecture diagram is mainly used to store a large amount of original transmissio...

Abstract

The invention provides a Hadoop-based distributed retrieval method for power transmission line monitoring videos. The method comprises the steps of based on a Hadoop platform, dividing massive video data storage into different video clips and storing the video clips in Blocks of Hadoop; extracting key frames under the assistance of OpenCV; performing similarity comparison on the key frames and a sample picture submitted by a user to obtain N key frames most similar to the sample picture, and obtaining the video clips corresponding to the key frames; and displaying a retrieval result in a Web interface, thereby finishing video data retrieval work. The distributed retrieval method provided by the invention has the advantages of quickness, high efficiency and expansibility in processing large-capacity data, and solves the high-performance demand problem of power transmission line monitoring video retrieval of large data volume.

Description

technical field [0001] The invention relates to the field of computer data processing, in particular to a Hadoop-based distributed retrieval method for transmission line monitoring video. Background technique [0002] As an important information carrier, video is an important content of multi-modal data content processing. Power transmission and transformation status monitoring in the power industry, smart business halls, and various computer rooms all have high requirements for video systems. With the rapid development of computer technology and digital image acquisition technology and the popularization and application of Internet, Internet of Things, sensor network and mobile Internet in ubiquitous cyberspace, in ubiquitous cyberspace, through massive sensors, intelligent processing equipment and other terminals to realize The effective connection between things and things, things and people, people and people, information and information, information and people, informa...
