Solution Overview

Problem

Existing image dimension measurement devices require manual adjustment of the rotation angle for cylindrical members, such as D-cut surfaces and holes, which is time-consuming and labor-intensive for users.

Innovation Solution

An image dimension measurement device with a rotation mechanism that automatically adjusts the rotation angle based on pre-set reference shapes, using a control system to identify and align measurement elements like D-cut surfaces and holes with the imaging section without user intervention, by calculating the relative rotation angles and controlling the rotation mechanism to capture images at optimal angles.

AI summary

Convenience is improved by enabling an imaging section to capture an image of a measurement element without adjustment of a rotation angle of a measurement object performed by a user. A control unit identifies a reference rotation angle during measurement, and calculates a measurement angle to measure a measurement element based on a relative rotation angle with respect to the reference rotation angle stored in advance. The control unit controls a rotation unit such that a rotation angle of the rotation unit becomes the measurement angle. The control unit executes a process of measuring a dimension of the measurement element based on a measurement object image captured by an imaging section when the rotation angle of the rotation unit becomes the measurement angle.
