摘要

In this study, an embedded remote video surveillance system based on ARM was build. The hardware system is composed of ARM S3C2440 processor, OV9650 CMOS camera, and mobile phone; and the software platform includes three modules-video capture, video processing, and video transmission. Moreover, an improved moving target detection algorithm was proposed, which combines real-time background updating and three frame differencing to reduce the impact from the gradient and emergency in ambient light when long-term monitoring. The test results showed that, when someone appears in the monitoring scene, the system will send the relevant video information to the user's mobile phone via e-mail, that is, an alarm is sent to the user to complete remote video surveillance. In addition, it can adapt to the changes in ambient light when long-term monitoring and also has a good resistance to the sudden appearance of highlight, having good security and stability.
