The Approach of Real-time Monitoring Based on Background Subtraction

Real-time monitoring is the important research content of safety domain and real-time control, and the study on its related key technology has great significance. In this paper, an algorithm of real-time monitoring is proposed, which is based on background subtraction. By using the frame image obtained from real-time monitor or video, the images are divided into moving object area and still area, which is used for updating the background. Then the moving area is compared with background to capture the moving object and its position, which is used to recognize the security of the monitored real-time system. Studying the problem the real-time system, and discussing the complete solution methods to the problem. Experiment results demonstrate that the algorithm can quickly and exactly detect the moving objects and give the alarm.
