IMAGE DE-NOISE RESEARCH ON SWITCHING ARC ACQUISITION SYSTEM

摘要：

Research on the switching arc motion is important for the improvement of low voltage apparatus. But the arcing time is very short in the operation of switchgear under real situation. In order to observe and analyze the whole process of arcing, the thesis presents a kind of visual simulation method based on arc image. Because of the strong radiation of arc, the weak reflection of contacts, and the shake of apparatus due to the impact of mechanical motion, the arc image was affected by noise during the process of switching arc image acquisition. In order to avoid the drawbacks, and to provide a clear arc image, a new type of mapping function is introduced in de-noise process which can get threshold from different scales and directions, based on the wavelet transform theory. Experiment result shows that the processed image with a good vision effect was obtained, and for showing the shape of arc more clearly.
