Embodiment Construction

[0058] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. In particular, the following examples are only used to illustrate the present invention, but not to limit the scope of the present invention. Likewise, the following embodiments are only some but not all embodiments of the present invention, and all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0059] The present invention provides an automatic registration method based on machine vision, which can realize the use of machine vision to take pictures and identify color standard images, and calculate the actual position for automatic registration. The registration is accurate, and the registration error caused by the color standard printing relationship can be avoided. accurate question. The automatic registration method is not limited to pri...

Abstract

The invention discloses an automatic register method, system and equipment based on machine vision. The automatic register method based on machine vision includes the following steps: an industrial control computer transmits calculated center distance deviation ([delta]X and [delta]Y) of actual color codes and reference color codes of all groups of cameras and register error data to a control system, the control system calculates transverse and longitudinal register values according to the transmitted center distance deviation ([delta]X and [delta]Y) of the actual color codes and the referencecolor codes of all the groups of the cameras and the register error data, and the control system carries out automatic register according to the calculated transverse and longitudinal register values. Through the method, the recognition of color code images by shooting can be realized by using the machine vision, an actual position is calculated for the automatic register, the register is accurate, and the problem of inaccurate register caused by color code printing can be avoided.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to an automatic registration method, system and equipment based on machine vision. Background technique [0002] The existing automatic registration schemes for printing equipment, bronzing equipment, and die-cutting equipment generally use a color mark sensor to identify the position of the color mark on the plate, and then perform automatic registration. The existing automatic registration solutions for printing equipment, bronzing equipment, and die-cutting equipment are very affected by the accuracy of the color mark sensor and the printing quality image of the color mark. If the color mark is not printed well, it is very likely that the automatic registration will be misjudged or The error is relatively large, resulting in inaccurate overprinting. Contents of the invention [0003] In view of this, the purpose of the present invention is to propose an automatic re...
