Real time river water level measuring instrument and method through positioning data filtering

摘要

SubjectThe present invention comprisesThe watershed area is small by filtering the water level measurement data of the riverThe reliability of the measured water level data is guaranteed even in the case of a steep steep river.About real-time river water level measuring apparatus and method through positioning data filteringMeasurement section for measuring water level of riverAn imaging data filtering section that filters the water level data measured by the measuring means with a variable volume scatter smoothing technique of a local linear regression basis through application of a resilient bandwidth;Water level calculation unit which calculates the water level of the river to be measured by using the positioning data which is filtered by the positioning material filtering part and the uncertainty of the water level measurement uncertainty is minimized;.
