DATA PROCESSING DEVICE, DISPLACEMENT OBSERVATION SYSTEM, DATA PROCESSING METHOD, AND DATA PROCESSING PROGRAM

摘要

PROBLEM TO BE SOLVED: To effectively suppress noise including non-Gaussian noise and to enhance followability to variation in data.;SOLUTION: The data processing device includes a forward smoothing processing section 11, a backward smoothing processing section 12, and a smoothing method determination section 13. The forward smoothing processing section 11 calculates time-series data of forward smoothing by sequentially smoothing the obtained unprocessed time-series data and the time-series data from the past to the present. The backward smoothing processing section 12 calculates time-series data of the backward smoothing by sequentially smoothing the forward smoothing time-series data from the present toward the past. The smoothing method determination section 13 determines the response of the forward smoothing processing section and the backward smoothing processing section according to an integral value within a predetermined period of a difference value between the backward smoothing time series data and the time-series data before processing or the forward smoothing time series data, or the time difference value of any of these time series data.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
