Claim 15:
16. The three-dimensional object modeling method according to claim 15, wherein in the 3D model generation step, a height value of an extracted height, which is taken as the extracted contour height hc′ of the contour of the specific category, from the camera to a top portion of a corresponding three-dimensional object in all the obtained three-dimensional point coordinates on the top plane contour of each three-dimensional object is replaced by an extracted height hc from the camera to a bottom portion of the corresponding three-dimensional object and length values and width values in all the obtained three-dimensional point coordinates on the top plane contour of each three-dimensional object remain unchanged, to obtain the bottom plane contour of each three-dimensional object,
the extracted contour height hc′, which is a height from the camera to the top portion of the corresponding three-dimensional object, of the contour of the specific category is obtained in a following manner: sorting from small to large height values of all three-dimensional point coordinates, which are obtained when the camera position is obtained, on at least one panoramic image of each three-dimensional object, and taking a median value or an average value of the height values sorted in front as the extracted contour height hc′, which is the height from the camera to the top portion of the corresponding three-dimensional object, of the contour of the specific category, and
the extracted height hf′ from the camera to the bottom portion of the corresponding three-dimensional object is obtained in a following manner: sorting from small to large the height values of all three-dimensional point coordinates, which are obtained when the camera position is obtained, on the at least one panoramic image of each three-dimensional object, and taking a median value or an average value of the height values sorted in rear as the extracted height hf′ from the camera to the bottom portion of the corresponding three-dimensional object.
