Claim 8:
9. The three-dimensional object modeling method according to claim 8, wherein the single-image plane contour generation step comprises:
inputting the at least two panoramic images of each three-dimensional object into the trained deep learning model to obtain a category of a contour feature corresponding to each pixel in the at least two panoramic images of each three-dimensional object;
extracting edge pixels that are at edges among pixels, whose contour features belong to a specific category, on each panoramic image of the at least two panoramic images of each three-dimensional object as specific category edge pixels;
assuming that all specific category edge pixels on each panoramic image of the at least two panoramic images of each three-dimensional object have the same height hc that serves as an assumed contour height of a contour of the specific category, projecting the specific category edge pixels on each panoramic image onto a three-dimensional plane to obtain specific category three-dimensional points corresponding to each panoramic image, and then forming a plane contour of each panoramic image in the three-dimensional space based on the specific category three-dimensional points corresponding to each panoramic image,
wherein the specific category comprises a top portion of a three-dimensional object in the panoramic image.
