Image Correction Technology Supporting Power Device Monitoring

An automatically monitoring method of electrical device is proposed in this paper. Various visualization monitoring systems are built to save maintenance costs and improve operation efficiency. Limited to the working principle of ordinary camera lens, obtained image is easy to produce image deformity and aberration. In order to solve this problem, an image correction method based on phase-only correlation (POC) in power industry is suggested to get the image information of the actual situation of device. Experimental results show that proposed method can effectively save testing cost and achieve a high correction accuracy of device image.
