Claim 17:
18. An image processing method, comprising:
a camera position acquisition step, wherein using a geometric relationship of at least two panoramic images shot for each three-dimensional object of at least one three-dimensional object to be processed, a position of a panoramic camera when shooting the at least two panoramic images of each three-dimensional object and three-dimensional point coordinates of matching feature points on the at least two panoramic images of each three-dimensional object are obtained;
a single-image plane contour generation step, wherein for each panoramic image of the at least two panoramic images of each three-dimensional object, a plane contour of the panoramic image in the three-dimensional space is generated based on a contour surrounded by edge pixels in pixels, whose contour features belong to a specific category, on the panoramic image; and
a scale normalization step, wherein a scale of the position that is obtained of the panoramic camera when shooting the at least two panoramic images of each three-dimensional object and scales of the plane contours of the at least two panoramic images of each three-dimensional object in the three-dimensional space are normalized, to obtain normalized plane contours of respective panoramic images in the three-dimensional space.
