Claim 11:
12. The three-dimensional object modeling method according to claim 1, wherein the multi-object splicing step comprises:
assuming that there are N plane contours of all panoramic images in the three-dimensional space, a p-th three-dimensional point of an n-th plane contour is indicated as Xpn, and the camera position where a panoramic image corresponding to the n-th plane contour is shot is indicated as {Rn, tn}, where Rn is a rotation matrix used to represent a rotation parameter of the camera position, and tn is a translation vector used to represent a translation parameter of the camera position, where N is an integer greater than 1, and n is an integer greater than or equal to 1,
selecting the camera position where a panoramic image corresponding to an i-th plane contour is shot as a reference coordinate system, and unifying the three-dimensional points of other plane contours under the reference coordinate system through a formula below:

Xpn→i=RiRn−1(Xpn−tn)+ti, and

converting all the three-dimensional points of the plane contours after the scale normalization except the i-th plane contour through the formula, to unify the three-dimensional points of all the plane contours under the same coordinate system, so as to splice the plane contours of the respective three-dimensional objects into the multi-object plane contour.
