Abstract
There is provided an identification method including obtaining first information for each of first pixels constituting a first image obtained by imaging the first object with a first camera, the first information related to reflected light from a first object including a body, obtaining second information for each of the first pixels, the second information corresponding to a distance from the first object to the first camera, obtaining an index value as a result of a calculation using the first information and the second information for each of the first pixels, and identifying a first area of the first image corresponding to the body by judging whether each of the first pixels belong to the first area based on the index value.
Claims11
An identification method comprising:
- obtaining first information for each of first pixels constituting a first image obtained by imaging the first object with a first camera, the first information related to reflected light from a first object including a body;
- obtaining second information for each of the first pixels, the second information corresponding to a distance from the first object to the first camera;
- obtaining an index value as a result of a calculation using the first information and the second information for each of the first pixels;
- and
- identifying a first area of the first image corresponding to the body by judging whether each of the first pixels belong to the first area based on the index value.
A projection method comprising:
- obtaining first information for each of first pixels constituting a first image obtained by imaging the first object with a first camera, the first information related to reflected light from a first object including a body;
- obtaining second information for each of the first pixels, the second information corresponding to a distance from the first object to the first camera;
- obtaining an index value as a result of a calculation using the first information and the second information for each of the first pixels;
- identifying a first area of the first image corresponding to the body by judging whether each of the first pixels belong to the first area based on the index value;
- and
- projecting a projection image from a projector on the first object, the projection image being sectioned into a second area corresponding to the first area and a third area other than the second area, the second area is filled with a first color, and the third area is filled with a second color.
An identification system comprising:
- a first camera;
- and
- at least one processor executes:
- obtaining first information for each of first pixels constituting a first image obtained by imaging the first object with the first camera, the first information related to reflected light from a first object including a body;
- obtaining second information for each of the first pixels, the second information corresponding to a distance from the first object to the first camera;
- obtaining an index value as a result of a calculation using the first information and the second information for each of the first pixels;
- and
- identifying a first area of the first image corresponding to the body by judging whether each of the first pixels belong to the first area based on the index value.
