Problems solved by technology
[0003] Existing image registration methods include interactive information method, sequential similarity detection algorithm, phase correlation method, etc. These registration methods do not fully consider the characteristics of product posture on the production line, resulting in a large amount of calculation and relatively slow image registration speed. Slow, difficult to adapt to the running tempo of production flow

The invention provides an image registration method and device, a storage medium and an image printing assembly line device, belonging to the technical field of image registration. The image registration method comprises the following steps: controlling a standard image to coincide with an image to be registered; controlling the standard image to perform a plurality of translation operations withrespect to the image to be registered and recording the result of each translation operation; selecting the optimal translation operation from all the translation operations; controlling the standardimage to perform the optimal translation operation; controlling the standard image to perform multiple multi-dimensional fine adjustment operations with the center of gravity of the standard image asa center and recording the results of each multi-dimensional fine adjustment operation; selecting the optimal multi-dimensional fine adjustment operation from all the multi-dimensional fine adjustmentoperations; and controlling the standard image to perform the optimal multi-dimensional fine adjustment operation. The image registration method does not need to cycle the translation operations andthe multi-dimensional fine adjustment operations, which saves a lot of computation and registration time, and improves the efficiency of image registration.
Description
technical field [0001] The present disclosure relates to the technical field of image registration, and in particular to an image registration method, device, storage medium and image printing assembly line equipment. Background technique [0002] With the extensive application of machine vision technology in the field of industrial production, image registration technology is widely used in different stations on the production line. For example, an industrial camera can be installed at the inspection station of the production line, and the pictures collected by the industrial camera are used to judge whether the product on the inspection station is qualified or not after image registration. [0003] Existing image registration methods include interactive information method, sequential similarity detection algorithm, phase correlation method, etc. These registration methods do not fully consider the characteristics of product posture on the production line, resulting in a la...
