ROAD SURFACE PROFILE CORRECTION PROGRAM AND ROAD SURFACE PROFILE CORRECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a road surface profile correction program and a road surface profile correction device that can improve the accuracy of a road surface profile by cancelling out a wavelength detection characteristic specific to a prescribed road surface measuring device in the road surface profile measured by the road surface measuring device.SOLUTION: A road surface profile correction program 1a corrects a road surface profile measured by a prescribed road surface measuring device. The road surface profile correction program causes a computer to function as: a correction filter calculation unit 31 that calculates a correction filter having a wavelength response inverse of a wavelength detection characteristic specific to the road surface measuring device; and a correction profile calculation unit 32 that calculates a correction profile by converting a measurement profile measured by the road surface measuring device into a signal in a space frequency region, applying the correction filter, and then inversely converting the resultant signal into a signal in a space region.SELECTED DRAWING: Figure 1
