1. A three-dimensional object modeling method, comprising:
a plane contour extraction step, wherein for at least one panoramic image shot for each three-dimensional object of at least one three-dimensional object to be processed, a plane contour of the at least one panoramic image of each three-dimensional object in a three-dimensional space is extracted;
a scale normalization step, wherein a scale of the plane contour of the at least one panoramic image of each three-dimensional object in the three-dimensional space is normalized based on a camera position, to obtain normalized plane contours of respective panoramic images in the three-dimensional space; and
a multi-object splicing step, wherein based on the camera position, rotation and translation operations are performed on three-dimensional point coordinates of the normalized plane contours of the respective panoramic images in the three-dimensional space, so as to unify the three-dimensional point coordinates in same one coordinate system, to splice plane contours of respective three-dimensional objects into a multi-object plane contour.
