Three-dimensional modeling method based on plane image

Abstract

The invention discloses a three-dimensional modeling method based on a plane image. The plane image after graying is subjected to edge detection to obtain edges of the image; dilation is used at the edges to remove the transition color between adjacent colors in the image; a bitmap is decomposed to a gray matrix, the outer contour of the matrix is acquired and segmented, each gray value is corresponding to one height, a segmentation point is enhanced to a height corresponding to the gray value, three adjacent segmentation points are used to form a triangular patch, normal vectors obtained by the triangular patch are used to determine an inner side and an outer side, and a three-dimensional model map is finally obtained. Through acquiring the gray values in the image, each gray value is corresponding to one height value, simple three-dimensional modeling is thus realized, the method is particularly suitable for three-dimensional test for kid teaching, and the kid can realize drawing ofa three-dimensional space model through a simple color drawing.

Description

technical field [0001] The invention relates to a 3D modeling method for computer graphics, in particular to a method for performing three-dimensional modeling based on plane images. Background technique [0002] 3D modeling systems are one of the most valuable applications in the field of computer graphics. After a long period of development, its functions have been very rich and powerful, and it has been widely used in many fields. However, the development of shape modeling methods in the field of graphics is relatively backward. The currently dominant 3D modeling systems include 3DMAX, SoftImage, Maya, UG and AutoCAD, etc., which adopt the WIMP modeling method, which means: windows, icons, menus and pointers. However, this traditional modeling method still has many shortcomings, such as: [0003] 1. Strong professionalism. Operating the system requires a certain understanding of the software and a certain software foundation, and it is not suitable for people without p...

Problems solved by technology

Operating the system requires a certain understanding of the software and a certain software foundation, and it is not suitable for people without professional training to operate

[0004] 2. When modeling, a lot of details and precise information are required, which is not conducive to the fuzzy conceptual design in the early stage

[0005] 3. During the modeling process, users need to frequently select and switch among various menus and icon buttons, which is not conducive to the natural expression of design ideas

[0006] 4. Not suitable for use on mobile devices

[0007] Due to these deficiencies in the traditional 3D modeling system, it is difficult for people without professional training to operate the system, and it needs to be operated with the help of complex equipment, which is not conducive to the promotion of this technology
