Print registration dataset

This dataset is constructed for testing image registration algorithms in print defect detection, simulating scenarios involving global linear deformations caused by camera angle deviations and changes in shooting distance, as well as local non-linear deformations induced by external forces and uneven placement surfaces during the acquisition of printed images. The original images of the dataset were collected using a machine vision platform in a laboratory that simulates industrial scenarios, covering typical printed product categories such as medicine boxes, cigarette and alcohol boxes, food packaging boxes, express delivery boxes, and document bags. It contains a total of 25,200 image pairs, which fully reflect the diversity in size, texture, and material of printed products in actual production.
