| Abstract: | In this paper, measuring the humidity of SF6 using cold mirror dew point meter is introduced. And image processing methods are used to replace the traditional manual testing and photoelectric detection method. For the limitation of the traditional methods, texture analysis method based on wavelet packet is put forward. The system＇s overall program is also introduced in this paper. The Matlab simulation result shows the method is effective. |
