Abstract

The invention relates to a 3D intelligent modeling method and system and a flexible manufacturing system of a 3D model. A single photograph or picture is converted into a 2D shadow picture; after a 3D model is constructed, the information of the 2D shadow picture is hidden in the 3D model, a shadow presented by the 3D model with the hidden information of the 2D shadow picture through illumination angle projection is in an original picture or photograph shape, and 3D intelligent modeling can be realized by methods, such as accumulation, splicing, stretching, extrusion and the like. The flexible manufacturing system of the 3D model enables a user to integrally experience the processes of 3D modeling and 3D printing, 3D modeling compatible data is created, stored, transmitted and managed for a user, and the user is guaranteed to carry out 3D printing at any time and place so as to realize the flexible manufacture of the 3D model.

Description

technical field

[0001] The invention relates to the technical fields of computer graphics and flexible manufacturing, in particular to a 3D intelligent modeling method and system and a 3D model flexible manufacturing system. Background technique

[0002] With the continuous advancement of technological development, 3D intelligent digitization and 3D printing technology are constantly merging and developing rapidly. Its application fields are becoming more and more extensive. In recent years, 3D modeling has played a huge role in the actual manufacturing process of industrial engineering fields such as geographic information, urban architecture, mechatronics, medical and aerospace; especially, 3D modeling The continuous compatibility and technological development of mold and 3D printing have made the application of 3D intelligent digital technology more and more perfect, realizing a new realm of using "virtual" to recreate "reality", and gradually expanding from the field of ...

Examples

Embodiment Construction

[0038] The present invention will be described below in conjunction with the accompanying drawings.

[0039] The invention relates to a 3D intelligent modeling method, which includes the steps of intelligently digitizing a 3D model, three-dimensional modeling of touch accumulative stitching, three-dimensional modeling of touch stretching, and three-dimensional modeling of touch extrusion. Wherein, in the intelligent digital generation step of the 3D model, the picture or photo is converted into a two-dimensional shadow picture using graphics processing technology, and the two-dimensional shadow picture includes black and white picture information; and then each pixel in the two-dimensional shadow picture is generated into a two-dimensional point cloud data, and endow the third-dimensional coordinate data, re-serialize the 3D point cloud data to form a 3D model; Grid unit division; then convert the screen coordinates of the touch points into three-dimensional world coordinates,...
