Title: PARAMETER ESTIMATION DEVICE, PARAMETER ESTIMATION METHOD, AND COMPUTER-READABLE RECORDING MEDIUM
Abstract:
A parameter estimation device 10 is a device for calculating a threshold value for separating a plurality of data points into outliers and inliers, and estimating a parameter which fits the inliers. The parameter estimation device 10 is provided with: a parameter estimation unit 13 for estimating a parameter using a plurality of data points as inputs; a threshold value decision unit 14 for calculating a threshold value on the basis of statistical information of a residual of each data point; and a convergence determination unit 15 for determining whether the parameter estimation is converged or not on the basis of the estimated parameter and the calculated threshold value, and, if it is determined that the parameter estimation is not converged, causes each of the parameter estimation unit 13 and the threshold value decision unit 14 to execute processing again.
