A Hadoop-based Distributed Retrieval Method for Transmission Line Monitoring Video

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...
