Abstract

The invention discloses a ceramic prototype three-dimensional mesh model generation method and device based on multi-view sketching, wherein the method comprises the following steps: acquiring ceramicprototype sketches of a plurality of orthogonal views, sequentially sampling the ceramic prototype sketches of the plurality of orthogonal views one by one, and acquiring the segment-by-segment sampling results; constructing an energy function according to the segment-by-segment sampling results, and obtaining the modeling curve by a minimization method; conducting three-dimensional mesh fillingon the modeling curve, and outputting the result. This method takes advantage of the characteristics of ceramic prototype design, takes the sketch of multiple views as input, and constructs the three-dimensional mesh model by correlation sampling and energy function minimization. The method improves the efficiency of ceramic prototype construction and is simple and easy to implement.

Description

technical field [0001] The invention relates to the technical fields of computer vision and computer graphics, in particular to a method and device for generating a three-dimensional mesh model of a ceramic prototype based on multi-view sketching. Background technique [0002] Related technologies, the generation of ceramic prototype models is an important issue in the field of ceramic design. The existing ceramic prototype generation methods mostly use the interactive operation of geometric features as input. For ceramic designers who are not familiar with interactive modeling of geometric features, it is difficult to quickly generate Ceramic prototype model. At the same time, this kind of generation process has obvious shortcomings in the process of communicating with users. Most of the time, customers' needs for ceramic products can be described through sketches. Therefore, building a sketch-based ceramic prototype generation method will form a public-oriented The simple...
