【 摘 要 】

The distributed vibration signal has a large amount of data. It can waste insufficient storage space and have low efficiency of data analysis. Therefore, the paper proposes to save data information in the image format. The images have the original signal feature. The Phi-OTDR is pre-processed by the smooth filter. After the filter, the signal is stored by the image format. The image is extracted by the improved Speeded-Up Robust Features. The signal feature is kept in the image. Then a series of experiments prove the methods effectiveness.
