Claim 5:
6. The three-dimensional object modeling method according to claim 5, wherein the scale normalization step comprises:
in a case where the camera position is obtained in the camera position acquisition step,
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 an extracted contour height hc′ of the contour of the specific category; and according to a ratio of the assumed contour height hc of the contour of the specific category to the extracted contour height hc′ of the contour of the specific category, generating normalized plane contours of at least two panoramic images of each three-dimensional object in the three-dimensional space based on the plane contours of the at least two panoramic images of each three-dimensional object in the three-dimensional space; and
in a case where the camera position is a camera definition height Hc′ that is predetermined,
according to a ratio of a camera assumed height Hc that is assumed to the camera definition height Hc′, generating normalized plane contours of at least two panoramic images of each three-dimensional object in the three-dimensional space based on the plane contours of the at least two panoramic images of each three-dimensional object in the three-dimensional space,
wherein the assumed contour height hc of the contour of the specific category is an arbitrarily assumed height.
