Title:
物理量補正システム
Document Type and Number:
Japanese Patent JP7000026
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a physical quantity correction system capable of correcting numerical diffusion error by high accuracy.SOLUTION: A physical quantity correction system that corrects physical quantities acquired on the basis of the characteristic curve method in xyz orthogonal coordinates includes: separation executing means (step S100) for separating into physical quantities for each frequency band by a low pass filter and a band pass filter; correction executing means (step S200) for acquiring a corrected physical quantity by multiplying physical quantities for each frequency band by different correction coefficients; and summing execution means (step S300) for summing the corrected physical quantities for each of the frequency bands, where the correction coefficient is calculated by an inverse number of an exponential function of a value obtained by multiplying a time by a damping coefficient γ and a constant.SELECTED DRAWING: Figure 6
