Research On Technologies Of Image Processing And Recognition Of Icing Transmission Lines

In order to recognize and calculate the icing thickness of transmission lines accurately,a method based on remote digital video image processing tectmology is introduced.The digital images gotten from the transmission line video stream which is sent to monitoring center are the research objects.They are processed by several pretreatment technologies,including gray processing,two-dimensional image segmentation.In the segmentation process,a new two-dimensional otsu method based on simulated annealing genetic algorithm is proposed. And then identifying whether there is ice stream in the images of transmission lines,if there is, processing it.Finally,an improved eight-connected region mark algorithm is used to mark the regions of different transmission lines.Through the calculation of pixels of each transmission line before and after being iced,an average ratio is gotten,and then the icing thickness of each transmission line is known.When the icing thickness of any transmission line oversteps the safe range,it will alarm and make it deiced,ensuring the safety of the electric power system.
