INFORMATION PROCESSING APPARATUS, METHOD, AND PROGRAM
First Claim
1. An information processing apparatus comprising:
- an acquisition unit configured to acquire features used for deriving a positional attitude of an imaging device from an image captured by the imaging device;
a setting unit configured to set a plurality of partial regions included in the image as a plurality of candidate regions to which a feature is to be added;
an evaluation unit configured to evaluate the plurality of set candidate regions;
a determination unit configured to determine a position and/or an orientation of a feature to be newly added based on the plurality of evaluated candidate regions; and
an output unit configured to output the determined position and/or the orientation.

Abstract
In order to shorten the time required for a setting operation of features, an information processing apparatus includes an acquisition unit configured to acquire features used for deriving a positional attitude of an imaging device from an image captured by the imaging device, a setting unit configured to set a plurality of partial regions included in the image as a plurality of candidate regions to which a feature is to be added, an evaluation unit configured to evaluate the plurality of set candidate regions, a determination unit configured to determine a position and/or an orientation of a feature to be newly added based on the plurality of evaluated candidate regions, and an output unit configured to output the determined position and/or the orientation.

17. An information processing apparatus comprising:
-
a unit configured to acquire features which are included in an actual scene captured by an imaging device and used for deriving a positional attitude of the imaging device; a unit configured to determine a feature to be newly deleted, from among features included in the actual scene, based on a distribution of the acquired features; and a unit configured to output the determined feature.

18. An information processing method comprising:
-
acquiring features used for deriving a positional attitude of an imaging device from an image captured by the imaging device; setting a plurality of partial regions included in the image as a plurality of candidate regions to which a feature is to be added; evaluating the plurality of set candidate regions; determining a position and/or an orientation of a feature to be newly added based on the plurality of evaluated candidate regions; and outputting the determined position and/or the orientation.

19. A non-transitory computer-readable storage medium storing at least one program for causing a computer to execute an information processing method, the information processing method comprising:
-
acquiring features used for deriving a positional attitude of an imaging device from an image captured by the imaging device; setting a plurality of partial regions included in the image as a plurality of candidate regions to which a feature is to be added; evaluating the plurality of set candidate regions; determining a position and/or an orientation of a feature to be newly added based on the plurality of evaluated candidate regions; and outputting the determined position and/or the orientation.
