Patent number: 11995077Abstract: According to one embodiment, a parameter optimization apparatus stores data sets which each include a first parameter value of a first number of dimensions and an observed value of an objective function corresponding to the first parameter value. The apparatus determines a search space of a second number of dimensions smaller than the first number of dimensions. The apparatus acquires one or more data sets each having a first parameter value present within a predetermined distance from the search space. The apparatus searches the search space for a first parameter value that may optimize the objective function, using a surrogate model of an objective function based on one or more data sets acquired.Type: GrantFiled: August 30, 2021Date of Patent: May 28, 2024Assignee: KABUSHIKI KAISHA TOSHIBAInventors: Hideyuki Nakagawa, Yasunori Taguchi, Hiro Gangi

Patent number: 10429166Abstract: A processing device includes: a coordinate acquisition unit that acquires a moving amount of a measuring probe and a probe output; a matrix generation unit that generates a correction matrix including linear correction elements and non-linear correction elements; and a probe output correction unit that corrects the probe output with the correction matrix. The coordinate acquisition unit acquires the moving amount and the probe output of the measuring probe in each of measurement points in a quantity larger than or equal to the sum of the number of the linear correction elements and the number of the non-linear correction elements. Consequently, a non-linear error of the probe output supplied from the measuring probe can be corrected, and thus shape coordinates of an object to be measured can be obtained with high accuracy.Type: GrantFiled: August 18, 2017Date of Patent: October 1, 2019Assignee: MITUTOYO CORPORATIONInventors: Hideyuki Nakagawa, Nobuhiro Ishikawa

Patent number: 10422636Abstract: A processing device includes: a pushing drive mechanism control unit that brings a measurement tip into contact with a surface of a calibration artifact at a single point in each of five directions are all normal directions to the surface of the calibration artifact; a scanning drive mechanism control unit that reciprocates the measurement tip on the surface of the calibration artifact on each of three planes perpendicular to one another; a coordinate acquisition unit that acquires a moving amount and a probe output of a measuring probe; a matrix generation unit that generates a correction matrix; and a probe output correction unit that corrects the probe output with the correction matrix. This enables an improvement in asymmetric probe characteristics of the probe output, which is outputted from the measuring probe, in a particular plane. Thus, shape coordinates of an object to be measured can be obtained with high accuracy.Type: GrantFiled: August 21, 2017Date of Patent: September 24, 2019Assignee: MITUTOYO CORPORATIONInventors: Hideyuki Nakagawa, Nobuhiro Ishikawa
