[0047] The noun concepts involved in this application are explained below:

[0048]Atrous Convolution: Also known as Dilated Convolution. Atrous convolution is obtained by adding holes to ordinary convolution. In the case of the same parameter amount, the receptive field of dilated convolution is larger than that of ordinary convolution. Among them, the larger the hole rate (or expansion rate) of the hole convo...

Abstract

The invention provides an identification code position positioning model training and positioning method and device, and electronic equipment. The method comprises the following steps: acquiring a target sample image set comprising sample images obtained by carrying out image acquisition on printing paper printed with at least one identification code; performing N rounds of training on the identification code position positioning model based on sample images in the target sample image set to obtain a trained identification code position positioning model, wherein the identification code position positioning model comprises a first preset number of convolutional layers and a second preset number of hollow convolutional layers, the first preset number is greater than the second preset number, the second preset number of hollow convolutional layers are interspersed in the first preset number of convolutional layers, and the identification code position positioning model is used for identifying the position of the identification code in the image, and the convolution layer and the cavity convolution layer are both used for extracting features related to the position of the identification code in the image. According to the invention, the positioning accuracy of the position of the identification code is improved.

Description

technical field [0001] The present application relates to printing technology, in particular to a training and positioning method, device, and electronic equipment for an identification code position positioning model. Background technique [0002] An identification code for recording the identification information of the item is usually printed on the packaging box of the item. As the identification information of items, item identification codes are widely used in market circulation testing, quality testing, and item anti-counterfeiting. According to the relevant standards for printing identification codes, and user needs, etc., the identification code needs to be printed at a specific position on the item packaging box. Therefore, it is necessary to detect the position of the printed identification code to determine whether the printed position of the identification code is correct. [0003] At present, it is mainly determined whether the printing position of the identi...
