Information processing method and information processing apparatus

摘要

A multi view-point image composed of a great number of images according to a shape of an object is generated or an information processing method used for generating a three-dimensional model or performing image processing of arbitrary view-point object recognition is provided, and based on a plurality of captured images obtained by imaging of the object from a plurality of view points by an imaging means, a relative position and orientation with respect to the object relative to the imaging means for each of the plurality of view points is calculated, and based on the calculated plurality of relative positions and orientations, a missing position and orientation of the imaging means in a direction in which imaging by the imaging means is missing is calculated, and an image used for displaying the calculated missing position and orientation on a display means is generated.

主权项

1. An information processing apparatus comprising:
a memory; and a processor coupled to the memory which executes the following: obtaining a plurality of relative positions and orientations with respect to an object relative to an imaging unit for each of a plurality of view points based on a plurality of images captured by imaging the object from the plurality of view points by the imaging unit; deriving, as a lacking relative position and orientation, a relative position and orientation of the imaging unit from which imaging by the imaging unit is lacking with respect to the object based on the obtained plurality of relative positions and orientations; and outputting information which indicates the derived lacking relative position and orientation, wherein the deriving includes: setting a plurality of virtual relative positions and orientations from which the object is imaged approximately uniformly with the object at a center; determining whether each of the virtual relative positions and orientations is similar to at least one of the obtained relative positions and orientations; and deriving the lacking relative position and orientation based on the virtual relative positions and orientations to each of which it is not determined that any of the obtained relative positions and orientations is similar.
