Three-dimensional modeling method based on multi-view geometric concept design

Abstract

The invention discloses a three-dimensional modeling method based on multi-view geometric concept design. The method comprises the following steps: constructing a multi-view geometric scene; hand-drawing a two-dimensional sketch in the multi-view geometric scene; identifying the two-dimensional sketch to obtain sketch elements of an image space; mapping the sketch elements to a three-dimensional space based on a multi-view geometric scene to form corresponding three-dimensional modeling elements; employing three-dimensional modeling elements as input, and completing the construction of basic voxels and a complex three-dimensional model; fusing the generated three-dimensional model into a multi-view geometric scene; repeating the steps, and adding a new image for the multi-view geometric scene. According to the scheme, a conceptual design scene in the brain of a person is abstracted into a multi-view geometric scene, and the process of constructing a three-dimensional model in the multi-view geometric scene is converted into the process of drawing a sketch on an image, which is more consistent with the thinking habit of a designer; the design efficiency can be improved, and a convenient and efficient support means is provided for three-dimensional modeling in the conceptual design stage.

Description

[0001] technical background [0002] The present invention relates to the field of image modeling techniques, and more particularly to a three-dimensional modeling method based on multi-view geometric concept. Background technique [0003] At present, with the increasingly fierce economic globalization and market competition, product innovation design capacity is increasingly becoming the key to enterprise survival. Due to uncertain factors, high degree of freedom, high creativity require high, conceptual design has become the core stage of innovation design, and the advanced concept design method has important application value for improving the core competitiveness of the enterprise and occupying market opportunities. Not only that, in the field of computer film and television animation, architecture, urban planning, advanced conceptual design methods and means have very broad application prospects. [0004] The image is the most close to the model representation of human thinkin...

Problems solved by technology

However, in the conceptual design stage, designers are more concerned about the functional form and structure of the product, and it is difficult to give accurate position, size and constraints. Therefore, the current CAD system is not suitable for the conceptual design stage, but more suitable for the Geometric design after product conceptual design proposal
