Embodiment Construction

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0029] Such as figure 1 As shown in the figure, it is a flow chart of the method for creating a two-dimensional curved surface with three-dimensional patterns based on the traditional technology according to the embodiment of the present invention. The principle of this method is as follows: first, a set of orthogonal projection surface images is obtained by rotating the model in situ; then all images are meshed and affine transformed, and the non-developable su...

Abstract

The invention discloses a two-dimensional method for a three-dimensional pattern of a traditional artware. The method comprises the following steps: firstly, rotating a three-dimensional curved surface model to obtain a plurality of orthogonal projection segments, and enabling the segments to have as many overlapping parts as possible; carrying out grid division and affine transformation by taking the obtained orthogonal projection sheet as a unit, and approximately processing the non-developable curved surface into a developable curved surface; after a deployable curved surface is obtained, curved surface segments of the deployable curved surface are unfolded through a boundary processing algorithm, and the concave-convex feeling of the curved surface segments is eliminated; and finally, splicing all processed planes into a complete two-dimensional image through a multi-plane splicing fusion algorithm for the expanded segments, and keeping the integrity and attractiveness of the image. According to the embodiment of the invention, the original shape and color of the pattern can be reserved, and the two-dimensional processing of the three-dimensional pattern curved surface is completed on the basis of no distortion.

Description

technical field [0001] The invention relates to the fields of image processing and computer vision, and relates to a two-dimensional method for three-dimensional patterns of traditional handicrafts, which involves curved surface development and image splicing. Background technique [0002] As a spiritual resource of culture, the three-dimensional patterned surface of traditional crafts belongs to culture and is an integral part of culture. The digital dissemination of cultural heritage is an indispensable part of cultural self-confidence and cultural power. With the continuous development of high technology, the digital technology of handicrafts has gradually matured. Especially with the development of three-dimensional technology, its application scope is also expanding, including restoration of cultural relics, technology display and so on. [0003] However, the focus of 3D process technology is still more focused on the modeling of the process. In addition to modeling,...
