Method of identifying a position of object in camera image
First Claim
1. A method of identifying images of three-dimensional objects displayed by a camera as a two-dimensional camera image, comprising the steps of:
- mapping coordinates of vertexes and a center point of a cursor window, including at least one of said objects from the camera image, the cursor window and the center point being mapped from two-dimensional coordinates into spherical polar coordinates with a position of said camera as an origin for the spherical polar coordinates;
pointing to a point in said camera image, said pointed-to point being mapped from said camera image to spherical polar coordinates with the position of said camera as the origin, the spherical polar coordinates of said pointed-to point being adjusted in accordance with at least one of an elevation angle, horizontal angle, and view angle of said camera; and
comparing said mapped pointed-to point with said mapped cursor window vertexes to identify an object included in the cursor window corresponding to said pointed-to point.

Abstract
The present invention relates to a method of identifying object images displayed in a camera image, the method comprising the step of, comparing a predetermined point mapped in the camera image in a spherical polar coordinates with a position of the camera as an origin, with a plurality of cursor windows including the object images respectively in the camera image, in which vertexes and center point of each window are mapped in the camera image in a spherical polar coordinates with a position of the camera as an origin, so that an object included in a cursor window corresponding to the predetermined point is identified.
