Abstract

The invention discloses a calibration auxiliary device, a calibration system and a calibration method. The calibration plate comprises a calibration plate body, wherein the calibration plate body is provided with a calibration plate top surface; calibration plate feature points are formed on the top surface of the calibration plate; a calibration plate groove with an upward opening is also formedin the top surface of the calibration plate; the calibration plate groove is used for accommodating a calibrated product, and the depth of the calibration plate groove is the same as the thickness ofthe calibrated product, so that when the calibrated product is placed in the calibration plate groove, the top surface of the calibrated product, the top surface of the calibration plate and the characteristic points of the calibration plate are positioned on the same plane. The method has the beneficial effects that the calibration precision is greatly improved, and the calibrated image can meetthe requirement of precise image measurement.

Description

Technical field [0001] The invention relates to the field of machine vision calibration, in particular, a calibration auxiliary device, a calibration system and a calibration method. Background technique [0002] In the field of machine vision calibration, the calibration method is basically to first calibrate the calibration board (such as the "robot vision system calibration board" announced by Chinese utility model patent CN202622812U) through the machine vision camera to determine the calibration coordinate system of the machine vision camera. Then move the calibration board out, move into the calibrated product, and calibrate the calibrated product under the aforementioned calibration coordinate system through the machine vision camera. In actual operations, the thickness of the calibration board and the thickness of the product to be calibrated are often different, and the accuracy of the aforementioned calibration coordinate system is reduced, which is not conducive to pre...
