Abstract

A circular shape characteristic measuring device includes a shape measuring device that obtains measured data by measuring a profile shape of a circular cross-section of an object to be measured having the circular cross-section, and a computation device that calculates a circular shape characteristic of the circular cross-section. The computation device includes: an input device configured to input one of three parameters including a cutoff value of the filtering process, a minimum number of samples, and a ratio of a radius of the circular cross-section to a radius of a gauge head; a parameter table that stores a relationship between the three parameters, and based on the input parameter, determines the other two parameters; and a sampler configured to perform sampling of the measured data based on the minimum number of samples.
