Abstract
Official abstract text for this publication.
An information processing apparatus comprises a processing unit that acquires, based on an image captured by an imaging unit and including an identifier disposed in a space, a plurality of positions on an outline of a shape of the identifier in an image coordinate system, and determines a position of the imaging unit, based on the plurality of positions on the outline of the shape of the identifier in the image coordinate system and positions on the outline of the shape of the identifier in a world coordinate system.
First claim
Opening claim text (preview).
What is claimed is: 1 . An information processing apparatus comprising: one or more processors configured to: acquire, based on an image captured by an imaging unit and including an identifier disposed in a space, a plurality of positions on an outline of a shape of the identifier in an image coordinate system, and determine a position of the imaging unit, based on the plurality of positions on the outline of the shape of the identifier in the image coordinate system and positions on the outline of the shape of the identifier in a world coordinate system. 2 . The information processing apparatus according to claim 1 , wherein the identifier has an asymmetric shape, and wherein the one or more processors determine the position of the imaging unit, based on a plurality of positions on the outline of the asymmetric shape of the identifier. 3 . The information processing apparatus according to claim 1 , wherein the one or more processors acquire, as the positions on the outline of the shape of the identifier in the image coordinate system, either positions of vertexes of the shape of the identifier or a center position derived from the positions of the vertexes. 4 . The information processing apparatus according to claim 1 , wherein the one or more processors determine whether a size of the identifier in the image captured is equal to or larger than a predetermined value, and determine the position of the imaging unit based on the plurality of positions on the outline of the shape of the identifier in the image coordinate system, in a case where the size of the identifier is determined to be equal to or larger than the predetermined value. 5 . The information processing apparatus according to claim 3 , wherein the one or more processors determine whether a size of the identifier in the image captured is smaller than a predetermined value, and acquire the center position of the identifier and determines the position of the imaging unit based on the center position, in a case where the size of the identifier is determined to be smaller than the predetermined value. 6 . The information processing apparatus according to claim 1 , wherein the one or more processors acquire a primary position of the imaging unit, based on the positions on the outline of the shape of the identifier in the image coordinate system and the positions on the outline of the shape of the identifier in the world coordinate system, associate, based on the primary position of the imaging unit and a position of the identifier in the world coordinate system, a position of the identifier in the image coordinate system with the position of the identifier in the world coordinate system, and determine the position of the imaging unit, based on the position of the identifier in the image coordinate system and the position of the identifier in the world coordinate system associated with each other. 7 . A non-transitory computer-readable storage medium storing a program that causes a computer to perform operations comprising: acquiring, based on an image captured by an imaging unit and including an identifier disposed in a space, a plurality of positions on an outline of a shape of the identifier in an image coordinate system; and determining a position of the imaging unit, based on the plurality of positions on the outline of the shape of the identifier in the image coordinate system and positions on the outline of the shape of the identifier in a world coordinate system. 8 . A positioning method comprising: acquiring, based on an image captured by an imaging unit and including an identifier disposed in a space, a plurality of positions on an outline of a shape of the identifier in an image coordinate system; and determining a position of the imaging unit, based on the plurality of positions on the outline of the shape of the identifier in the image coordinate system and positions on the outline of the shape of the identifier in a world coordinate system.
