Abstract

An information processing device includes an image acquirer that acquires a shot image of an object having a marker, a marker detector that detects an image of the marker from the shot image, and an information processing section that executes information processing based on a detection result by the marker detector. The marker detector identifies the image of the marker among color regions that are extracted from the shot image and have predetermined colors based on the positional relationship between a region that is assumed when one color region of the color regions extracted is a marker and is covered by an image of an object having the marker and another color region extracted.

Claims

1. An information processing device comprising:

an image acquirer configured to acquire a shot image of an object having a marker;

a marker detector configured to detect an image of the marker from the shot image; and

an information processing section configured to execute information processing based on a detection result by the marker detector,

wherein the marker detector identifies the image of the marker among color regions that are extracted from the shot image and have predetermined colors based on a positional relationship between a region that is assumed when one color region of the color regions extracted is a marker and is covered by an image of an object having the marker and another color region extracted.

2. The information processing device according to claim 1, wherein the marker detector acquires distance of the object from a camera and derives the region covered by the image of the object based on the distance.

3. The information processing device according to claim 1, wherein the marker detector assumes, for the color regions extracted, the region covered by the image of the object when the color region is deemed as a marker in decreasing order of area of the color region, and excludes another color region at least part of which is included in the assumed region from the detection result of the image of the marker.

4. The information processing device according to claim 2, wherein the marker detector acquires distance of a person who is holding the object from the camera and estimates the distance of the object from the distance of the person.

5. An information processing method comprising:

acquiring a shot image of an object having a marker and storing the shot image in a memory;

detecting an image of the marker from the shot image read out from the memory; and

executing information processing based on a detection result,

wherein the detection of an image of the marker includes identifying the image of the marker among color regions that are extracted from the shot image and have predetermined colors based on a positional relationship between a region that is assumed when one color region of the color regions extracted is a marker and is covered by an image of an object having the marker and another color region extracted.

6. A computer program for a computer, comprising:

acquiring a shot image of an object having a marker and storing the shot image in a memory;

detecting an image of the marker from the shot image read out from the memory; and

executing information processing based on a detection result,

wherein the detection of an image of the marker includes identifying the image of the marker among color regions that are extracted from the shot image and have predetermined colors based on a positional relationship between a region that is assumed when one color region of the color regions extracted is a marker and is covered by an image of an object having the marker and another color region extracted.

7. A computer-readable recording medium in which a computer program is recorded, the computer program for a computer including:

acquiring a shot image of an object having a marker and storing the shot image in a memory;

detecting an image of the marker from the shot image read out from the memory; and

executing information processing based on a detection result,

wherein the detection of an image of the marker includes identifying the image of the marker among color regions that are extracted from the shot image and have predetermined colors based on a positional relationship between a region that is assumed when one color region of the color regions extracted is a marker and is covered by an image of an object having the marker and another color region extracted.
