Embodiment Construction

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

[0049] figure 1It is an architecture diagram of a distributed retrieval method for transmission line surveillance video based on Hadoop. With the support of HDFS and Map / Reduce modules of Hadoop platform, it is supplemented by OpenCV (an open source computer vision library) vision library and key frame extraction. Algorithm, the 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 the retrieval results are displayed on the web interface. The HDFS part in the architecture diagram is mainly used to store massive amounts of or...

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 distributed retrieval method for monitoring video of transmission lines based on Hadoop. Background technique [0002] As an important information carrier, video is an important content of multimodal data content processing. Power transmission and transformation status monitoring, intelligent business halls, and various computer rooms in the power industry all have high requirements on video systems. With the rapid development of computer technology and digital image acquisition technology and the popularization and application of the Internet, Internet of Things, sensor network and mobile Internet in the ubiquitous cyberspace, in the ubiquitous cyberspace, through massive sensors, intelligent processing equipment and other terminals The effective connection between things and things, things and people, people and people, information and information, information and peo...
