PROBLEM TO BE SOLVED: To simply express a physical phenomenon in a two-dimensional plane or a three-dimensional space by a simple physical equation.SOLUTION: A data estimation method for estimating a physical quantity of a physical phenomenon in a two-dimensional plane or a three-dimensional space in a data estimation device connected to a plurality of sensors, includes the steps of: acquiring measurement data output from the sensors in time series, and storing the measurement data in data storage means; reading the measurement data stored in the data storage means, and mapping the measurement data on one two-dimensional plane or three-dimensional space at every arbitrary time; and estimating a velocity vector from the mapped measurement data on the basis of a spatial distribution and a time series change, calculating spatial interpolation and a temporal prediction by a physical equation using a diffusion coefficient, and outputting estimation data. |
