Information processing apparatus, information processing method, and computer program
There is provided an information processing apparatus including an image acquisition unit configured to acquire images captured from a plurality of observation points for a predetermined object, a feature point extraction unit configured to extract a feature point in each of the images acquired by the image acquisition unit, a correspondence relationship acquisition unit configured to acquire a correspondence relationship of the feature points based on images from among adjacent observation points, and an information presentation unit configured to quantitatively present information about the correspondence relationship acquired by the correspondence relationship acquisition unit.
1. An information processing apparatus comprising:
an image acquisition unit configured to acquire images captured from a plurality of observation points for a predetermined object;
a feature point extraction unit configured to extract a feature point in each of the images acquired by the image acquisition unit;
a correspondence relationship acquisition unit configured to acquire a correspondence relationship of the feature points based on images from among adjacent observation points; and
an information presentation unit configured to quantitatively present information about the correspondence relationship acquired by the correspondence relationship acquisition unit.
2. The information processing apparatus according to claim 1 , wherein
the information presentation unit is configured to quantitatively present information about the correspondence relationship between a predetermined observation point and an observation point adjacent to that observation point.
3. The information processing apparatus according to claim 2 , wherein
the information presentation unit is configured to present a line that links the feature points as the information about the correspondence relationship.
4. The information processing apparatus according to claim 2 , wherein
the information presentation unit is configured to virtually generate and present an image from an observation point between the predetermined observation point and the observation point adjacent to that observation point as the information about the correspondence relationship.
5. The information processing apparatus according to claim 2 , wherein
the information presentation unit is configured to change and present a display of the information about the correspondence relationship at the predetermined observation point based on the number of correspondence relationships acquired between the predetermined observation point and the observation point adjacent to that observation point as the information about the correspondence relationship.
6. The information processing apparatus according to claim 5 , wherein
the information presentation unit is configured to present information about the correspondence relationship at the predetermined observation point as a change in color.
7. The information processing apparatus according to claim 5 , wherein
the information presentation unit is configured to present information about the correspondence relationship at the predetermined observation point as a change in grayscale.
8. The information processing apparatus according to claim 2 , wherein
the information presentation unit is configured to present information about the correspondence relationship between the predetermined observation point and the observation point adjacent to that observation point in graphical form projected on a spherical surface.
9. The information processing apparatus according to claim 1 , wherein
the correspondence relationship acquisition unit is configured to, when acquiring a correspondence relationship for the feature points based on images from among adjacent observation points, use information about a feature quantity of the feature points.
10. The information processing apparatus according to claim 1 , wherein
the image acquisition unit is configured to acquire images about the predetermined object from an observation point selected based on information about the correspondence relationship presented by the information presentation unit.
11. A non-transitory computer readable medium having stored thereon, a computer program having at least one code section executable by a computer, thereby causing the computer to perform steps comprising:
acquiring images captured from a plurality of observation points for a predetermined object;
extracting a feature point in each of the images acquired in the image acquisition step;
acquiring a correspondence relationship of the feature points based on images from among adjacent observation points; and
quantitatively presenting information about the correspondence relationship acquired in the correspondence relationship acquisition step.
