System, method and program for perspective projection image creation, and recording medium storing the same program
First Claim
1. A perspective projection image creation system, comprising:
- an optical system including a hyperboloidal mirror which has a hyperboloidal shape of one sheet of a two-sheeted hyperboloid;
an imaging section receiving light concentrated by a lens opposed to the hyperboloidal mirror so as to create input image data;
an image transformation section transforming input image data obtained by the imaging section into image data of a perspective projection having a projection center at a focal point of the hyperboloidal mirror;
a scale model creation section transforming image data for an object in an object plane perpendicular to a line extending through a focal point of the hyperboloidal mirror into image data for a scale model of the object, based on a ratio of a distance between the focal point of the hyperboloidal mirror and the object plane to a distance between the focal point of the hyperboloidal mirror and a perspective projection image plane, such that a size of the scale model of the object corresponds to that of the object in a perspective projection image;
an image combining section creating combined image data created by combining the perspective projection image data and the image data for the scale model; and
a display section displaying the combined image data.

Abstract
A perspective projection image creation system of the present invention includes: an optical system including a hyperboloidal mirror; an imaging section receiving light so as to create input image data; an image transformation section transforming input image data obtained by the imaging section into image data of a perspective projection; a scale model creation section transforming image data for an object in an object plane into image data for a scale model of the object such that a size of the scale model of the object corresponds to that of the object in a perspective projection image; an image combining section creating combined image data created by combining the perspective projection image data and the image data for the scale model: and a display section displaying the combined image data.

9. A method for creating a perspective projection image, comprising the steps of:
-
obtaining input image data using an omnidirectional vision sensor, the omnidirectional sensor including an optical system which includes a hyperboloidal mirror having a hyperboloidal shape of one sheet of a two-sheeted hyperboloid and the omnidirectional sensor including an imaging section which receives light concentrated by a lens opposed to the hyperboloidal mirror so as to obtain input image data;
transforming input image data obtained by the imaging section into image data of a perspective projection having a projection center at a focal point of the hyperboloidal mirror;
creating a scale model by transforming image data for an object in an object plane perpendicular to a line extending through a focal point of the hyperboloidal mirror into image data for a scale model of the object, based on a ratio of a distance between the focal point of the hyperboloidal mirror and the object plane to a distance between the focal point of the hyperboloidal mirror and a perspective projection image plane, such that a size of the scale model of the object corresponds to that of the object in a perspective projection image;
combining the perspective projection image data and the image data for the scale model so as to create combined image data created; and
displaying the combined image data. - View Dependent Claims (10, 11)
