UV imaging is an effective method to detect the early high voltage equipment corona discharge,to extract the UV image discharge region can obtain the contour.It helps us to study the corona discharge qualitatively and quantitatively.According to the discharge UV image feature,Using mathematical morphology algorithm,the noise and discrete discharge image are filtered effectively,and the main discharge regions are extracted,Using region labeling and the multi region boundary tracing algorithm,the discharge region contour and the boundary pixel coordinate value are obtained.According the coordinate value,the area,perimeter and the diameter are calculated.Practical application shows its effectiveness.
