Problems solved by technology

Since the running time of the intelligent video processing task cannot be known in advance, and the processing capacity of the intelligent video analysis server (IVU) changes with time, it can be seen that when the traditional distributed task scheduling method is applied to the intelligent video surveillance system, it is easy to Unbalanced processor cluster load and insufficient resource utilization cannot meet the current intelligent surveillance video processing task requirements

Abstract

The embodiment of the invention discloses an off-line task scheduling method and device for an intelligent video monitoring system. The off-line task scheduling method for the intelligent video monitoring system is applied to a server in the video monitoring system. The video monitoring system further comprises a plurality of processors used for processing off-line tasks of the intelligent video monitoring system and a processing capability model pre-established for the processors. The method comprises the steps that an off-line task request of the intelligent video monitoring system is received, and the task request comprises at least one task to be processed; the weighting time length of each task to be processed is calculated; according to the processing capability model, the time needed for processing all the tasks to be processed at present of each processor is calculated; according to the weighting time length and the time, the tasks to be processed in the task request are scheduled to the processors. By means of the off-line scheduling method and device, the loads of the processors can be balanced..

Description

technical field [0001] The invention relates to the technical field of offline tasks of an intelligent video monitoring system, in particular to a method and device for scheduling offline tasks of an intelligent video monitoring system. Background technique [0002] In the face of a large number of surveillance videos, although the traditional offline video processing system uses Intelligent Video Analysis (IVA) technology, due to the limitation of the computing power of a single computer, it is usually unable to complete the surveillance video processing task within the time required by the customer. So we introduced distributed processing technology. In distributed computing, task management, task scheduling and resource management are the three basic functions of the system, among which task scheduling is an important aspect that affects the performance of the system. Task scheduling is an important part of the operating system, and for real-time operating systems, task ...
