Tool measuring and positioning device, has evaluation unit determining image positions of characteristic of calibration object from two images, and determining aberration of camera by comparing image positions with target positions

摘要

The device has a camera (10) for measurement of characteristic of a tool (14), and a measuring device to determine camera positions. An evaluation unit (18) determines image positions of the characteristic of a calibration object (24) from two images acquired from different camera positions in a calibration process and determines an aberration of the camera by comparing the image positions with target positions determined from the camera positions.
