MARKER RECOGNITION DEVICE, MARKER RECOGNITION METHOD, AND RECOGNITION PROGRAM

摘要

A marker recognition device includes: an image acquisition unit that acquires an image including a marker having a predetermined feature value; a detection unit that generates scale-space image groups by applying a disturbance to the image including the marker acquired by the image acquisition unit, and detects a key point in the image including the marker by detecting the predetermined feature value based on a difference between the generated scale-space image groups; and a recognition unit that recognizes a position of the marker based on the key point detected by the detection unit.

1. A marker recognition device comprising:
image acquisition means for acquiring an image including a marker having a predetermined feature value; detection means for generating scale-space image groups by applying a disturbance to the image including the marker acquired by the image acquisition means, and for detecting a key point in the image including the marker by detecting the predetermined feature value based on a difference between the generated scale-space image groups; and recognition means for determining whether or not a marker is present at a position of the key point detected by the detection means, and for recognizing a position of the marker based on the position of the key point where the marker is present, the key point being detected by the detection means.
