Abstract

At present, in the analysis task of hundreds of video streams, the general processing method is to pull the video streams to the data center and apply a graphics processing unit (GPU) cluster for centralized analysis and processing. However, the cost and power consumption of establishing GPU clusters are relatively high, and GPU clusters are not good at processing large quantities of video streams. For the above scenarios, this paper proposed an edge real-time video analysis system based on distributed Artificial Intelligence (AI) cluster. A distributed software platform based on distributed Advanced RISC Machine (ARM) cluster and Akka cluster technology was established. It achieves distributed cluster state management, two-level horizontal capacity expansion, three-level task scheduling mechanism and complete data link processing. The core functions of the whole system include distributed cluster state management, two-level horizontal expansion, etc. The three-level task scheduling mechanism and the processing of complete data links are realized. RK3399 Pro was applied as the carrier of real-time computing. The measured data shows that compared with the embedded single board, the system can improve the AI computing speed by more than 20 times, which is comparable to the computing effect of GPU. It is suitable for the application scenarios of recalculation power such as real-time AI computing.
