AI Technical Summary

Technical Problem

The prior art is difficult to efficiently and accurately detect the inkjet area on product packaging, especially due to the different shapes, sizes and arrangements of product packaging.

Method used

By acquiring and preprocessing the image acquisition sample containing the coded area, the instance segmentation results and rotation object detection results of the target to be detected in the image acquisition sample are determined, and the positioning information of the coded area is then determined. This method introduces a rotation detection mechanism to adapt to different shapes, sizes and arrangements of the inkjet region.

Benefits of technology

It realizes fast and accurate positioning of the inkjet coding area, effectively improves the detection accuracy problems caused by different product packaging shape, size and arrangement methods, and meets the higher requirements for inkjet coding use.

Abstract

The invention relates to a code spraying area positioning method and device, computer equipment and a readable storage medium. The method comprises the following steps: acquiring an image acquisition sample page containing a code spraying area, and preprocessing the image acquisition sample page; according to the preprocessed image acquisition specimen, determining an instance segmentation result and a rotation target detection result of a to-be-detected target in the image acquisition specimen; and determining positioning information of the code spraying area according to the instance segmentation result and the rotating target detection result. According to the method, the feature distribution of the code spraying area in the image acquisition sample page is rapidly extracted, so that the code spraying area is rapidly and accurately positioned in time, and the problem that it is difficult to efficiently and accurately detect the code spraying area on each product package due to different shapes, sizes and arrangement modes of the product packages is effectively solved; and higher requirements of code spraying use are met.
