Title:
IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, IMAGE PROCESSING PROGRAM, AND IMAGE PROCESSING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/087673
Kind Code:
A1
Abstract:
The present invention facilitates association between an object and a stable refection point on an image. This image processing device is provided with: a stable reflection point identification unit; a phase acquisition unit; and a clustering unit. The stable reflection point identification unit of the image processing device identifies stable reflection points where reflections are stable on a plurality of images. The phase acquisition unit of the image processing device acquires phases of the identified stable reflection points. The clustering unit of the image processing device clusters the stable reflection points on the basis of the positions and the phases of the stable reflection points.
