摘要: 以艺术陶瓷异形外曲面为研究对象,提出一种基于虚拟现实技术的三维重构方案:利用立体视觉原理布置相机,配合面结构光投影技术采集艺术陶瓷异形外曲面图像;采用均值滤波方法处理采集图像,并以全卷积网络为基础,设置自动分割网络;设计虚拟三维数据场,在数据场内制作三维直接体,生成陶瓷异形外曲面重构结果。实验结果表明,与传统方法相比,本文方案曲面重构偏差显著减小,生成的三维模型完整、清晰,可为艺术陶瓷的再设计提供解决思路,促进产品智能化设计和生产。Abstract: Taking the special-shaped surface of art ceramics as the research object, a 3D reconstruction scheme based on virtual reality technology was proposed. The camera was arranged based on stereo vision principle, and the images of special-shaped surface of art ceramics were collected by surface structured light projection technology. The mean filtering method was used to process the collected images, and the automatic segmentation network was set up based on the full convolutional network. 3D reconstruction algorithm based on virtual reality technology was developed and virtual 3D data field was designed; The 3D direct volume was fabricated in the data field, and the reconstruction result of the special-shaped surface was generated. The experimental results showed that compared with the traditional method, the surface reconstruction deviation of the proposed scheme could be significantly reduced, and the generated 3D model was complete and clear, which provided a solution for the redesign of artistic ceramics and promoted the intelligent design of products.
