The group meeting is "Distributed Fiber Optical Sensing in high-speed railway vibration detection, and experimental analysis based on image processing", during which we introduced a image processing method to improve the performance of optical fiber sensing, and discussed whether this method could be used in the relevant vibration sensing job of our own group. Short-time Fourier transform processing was used to analyze the field test data of high-speed railway vibration. The charactere of time and frequency variation of high-speed rail is preliminarily obtained, by the image denoising method. Then, the group team discussed the contents of the report and analyzed the problems we mentioned.
