AI Technical Summary
Technical Problem
Feature point matching between multiple images is not easy and presents challenges with existing technologies.
Method used
By generating a reference image, the color of the transparent part of the object image is set as the medium color, and the color information of the outer part is appended to the read image. Image alignment is performed using feature point matching technology, and feature points are detected and calculated using Accelerated-KAZE technology for feature point matching.
Benefits of technology
It improves the accuracy and reliability of image feature point matching, and can properly perform feature point matching between read images and reference images, thereby enhancing the precision of image inspection.

Abstract
Feature point matching between a plurality of images is performed. A generation process of generating a reference image using printed image data representing an object image is executed. A process of performing feature point matching using a plurality of feature points in a read image and a plurality of feature points in the reference image is executed. The read image is generated by optically reading the object image printed on a medium using the printed image data. Here, the reference image includes a reference transmission portion representing no color material or no color material, and the generation process can include a process of setting a color of the reference transmission portion to a color representing the medium, that is, a medium color. In addition, the generation process can include an addition process of adding an outer portion to the reference image, the outer portion being a portion outside the object image and displaying a color representing the medium, that is, a medium color.
