Claim 4:
5. The three-dimensional object modeling method according to claim 2, wherein the camera position is predetermined or obtained in the camera position acquisition step,
the camera position acquisition step comprises:
using a geometric relationship of at least two panoramic images shot for each three-dimensional object of the at least one three-dimensional object to be processed, performing feature point matching between the at least two panoramic images of each three-dimensional object, and recording feature points that match with each other in the at least two panoramic images of each three-dimensional object as the matching feature points; and
for each panoramic image of the at least two panoramic images of each three-dimensional object, reducing reprojection errors of the matching feature points on each panoramic image to obtain the camera position of the panoramic camera when shooting each panoramic image and the three-dimensional point coordinates of the matching feature points on each panoramic image.
