The present disclosure provides a three-dimensional object modeling method, an image processing method, and an image processing device. The three-dimensional object modeling method includes: a plane contour extraction step, in which for at least one panoramic image shot for each three-dimensional object, a plane contour of the at least one panoramic image in a three-dimensional space is extracted; a scale normalization step, in which a scale of the plane contour of the at least one panoramic image 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, in which based on the camera position, rotation and translation operations are performed on three-dimensional point coordinates of the normalized plane contours, so as to unify the three-dimensional point coordinates in the same coordinate system, to splice plane contours of respective three-dimensional objects into a multi-object plane contour.
