Image Surveillance System in the Unattended Substation Based on Harris Corner Detection
The applications of the remote image surveillance in the unattended substation were limited by the narrow bandwidth of wireless communication network.A novel method is proposed to adapt the wireless environment.The technique,implemented to obtain the digital instruments reading which is set as the ROI (region of interest) automatically,utilizes Harris corner detection.Then the ROI encoding in JPEG2000 technology is used in the image of the region of interest compressed at a higher quality than the rest of the image.The instruments reading information of unattended substation can be transmitted to dispatching center using wireless network effectively.Results show that the proposed method is feasible in terms of image quality and compression,adapting the narrow bandwidth,and improving the image of the real-time transmission.
