Problems solved by technology

[0003] Theories and methods based on single image 3D reconstruction technology have achieved certain results, including single image 3D reconstruction based on feature statistical learning method, shape restoration technology, single image 3D reconstruction technology based on geometric projection information, and single image 3D reconstruction technology based on geometric projection information. The single image 3D reconstruction technology achieved a relatively ideal reconstruction effect on the target image with geometric structure, but each method still has its own shortcomings and limitations.

Embodiment Construction

[0082] Such as figure 1 As shown in the present invention, a method for realizing a three-dimensional modeling based on a single picture, specifically includes the following steps:

[0083] Step 1. Input a single image and image segmentation

[0084] Based on the Unity3D development platform, use rendering texture (RTT for short) to realize the display of image files, and use OpenCvSharp to read local files, save them as Mat type, convert them into byte array type through ToBytes method, and then convert them into Texture2D type, and then display in the window;

[0085] Image segmentation includes foreground and background segmentation, using the difference in texture information and boundary information between the foreground and background, combined with a small amount of user interaction, to achieve foreground segmentation, obtain and save the required mask image, foreground image, and texture information;

[0086] Step 2. Combining the mask image in step 1, detect the ou...

Abstract

The invention discloses an implementation method for three-dimensional modeling based on a single picture, obtains foreground and background through image segmentation on a single picture input by a user, recognites and detectes four structural elements of a base, a layer, a cap and an edge in the foreground , carries out three-dimensional reconstruction through the modeling method of layered modeling and curve Morphing to achieve the effects of smooth, transitional and irregular curved surface modeling, and finally, carries out gridding, texture mapping and three-dimensional model format output to realize the three-dimensional modeling. According to the implementation method for three-dimensional modeling based on a single picture, the huge calculation amount and complex operation of multiple picture modeling are avoided, the real-time performance is good, the calculation amount is small, the visualization effect is good, and the application prospect and the application field are wide.

Description

technical field [0001] The invention belongs to the fields of three-dimensional reconstruction and computer graphics, in particular a three-dimensional modeling realization method of a single picture based on base-edge-hat-layer structure, layer modeling and curve Morphing. Background technique [0002] 3D reconstruction is a mathematical simulation and computer computing technology that reconstructs the 3D information, shape, texture, etc. of an object based on image information. It reconstructs a three-dimensional model with geometric information according to the data information provided by the picture. These 3D models can not only provide functions in virtual simulation, visualization, measurement, analysis, etc., but also have broad application prospects and application fields in the fields of digital cultural relics, 3D printing, virtual reality, augmented reality, and mixed reality. Research methods on 3D reconstruction include 3D reconstruction methods in the sense ...
