Abstract

The present invention provides an Hadoop-based video processing method and a system. The method comprises the steps of uploading to-be-processed video files to a Hadoop distributed file system; based on Fuse-DFS sub-items, mounting to-be-processed video files on a local file system at each of all cluster nodes of the Hadoop distributed file system; and invoking the OpenCV and FFMEPG to conduct the parallel analysis on MapReduce-based parallel computational models of to-be-processed video files mounted on the local file system and stored in the Hadoop distributed file system by means of Java CV. By means of the video processing method, the acceleration in proportional to the number of cluster nodes is realized for the Hadoop system.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of digital image processing, in particular to a Hadoop-based video processing method and system. Background technique [0002] At present, large-scale video surveillance systems are deployed more and more in traffic control, such as traffic intersections, highways, etc., and sensitive public places, such as airports, railway stations, banks, etc., resulting in a large amount of video data. [0003] More and more massive video data has the demand of processing and analysis. This demand exceeds the ability of manual processing, and even the time for traditional computer processing programs to face large-scale video data pre-processing exceeds the range that the demand can bear. Supercomputing is one way to solve problems. However, the supercomputer itself is expensive, and the operation and maintenance costs cannot be underestimated, which is unaffordable for ordinary users. Contents ...
