Disclosed is a panoramic space modeling method for observation of an object, which can observe an object without a special photographing environment by geometrically modeling a photographing environment of a camera which observes the object. The method comprises the steps of: (a) in a coordinate system for a 3D space defined by an x axis set for a left bottom direction of a specific photographing space, an y axis set for a vertical direction of the specific photographing space, and a z axis set for a right direction of the specific photographing space, photographing an object while maintaining an identical distance with respect to a center point of the object and horizontally rotating a camera by a predetermined angle in the x- and z-axis directions; (b) after photographing the object while maintaining the identical distance with respect to the center point of the object and horizontally rotating the camera by the predetermined angle in the x- and z-axis directions, modeling a panoramic space having a three dimensional trumpet shape in the 3D space coordinate system by forming a curved surface along a circular trajectory by consecutively photographing the object while vertically rotating the camera at a fixed location by a predetermined angle and matching images photographed through the vertical rotation of the camera; and (c) generating an object panoramic image having a trumpet shape, formed by a set of circles having different radii due to a center of an interior of the object and a focal length (Fc) of the camera, by mapping matched images of the object, photographed through the vertical and horizontal rotation of the camera during the modeling of the object panoramic space, to a panoramic space model. |
