Abstract
In order to improve the effect of substation operation remote video monitoring system, a new image mosaic method based on Canny operator and Harris corner detection is presented. Firstly, the edge feature points from two images are extracted by Canny edge detection; secondly, the corner feature points are extracted by Harris corner detection based on edge images; thirdly, the corresponding feature point pairs are got by the normalized cross correlation method around the corner feature points; finally, the images can be stitched by matched corner feature point pairs. The experiment of remote viewing image mosaic in substation shows that this method can achieve image mosaic effectively and it will be benefited to improve the safety and reliability of substation operation.
