Video Surveillance System for Extra-high Voltage Power Transmission Lines with an Optimal Image Compression Method

摘要

This paper presents a real-time online monitoring system scheme for power transmission line to achieve the objective of giving early warning to disaster and making decision for extra-high voltage power transmission line. Monitoring terminals with a S3C6410 ARM11 processor as core is equipped on the line towers to get the video data captured by the camera on board and other important information. An image optimal compression ratio is discussed based on JPEG2000 baseline compression in RGB space, and then a mathematical model for co-relationship of three color components in RGB is developed. The system has been installed on the power transmission line and works for a long time, and then it has indicated that the work efficiency of detecting the transmission line is raised.
