Development of pottery image reconstruction enhancement and reconstruction platform

陶器制作工艺和长时间保存下,会出现各种损伤问题。针对以上问题,设计了一套陶器图像的数字纹理修复、纹饰增强和三维交互展示系统。在获取陶器图像并梳理损伤问题,基于OpenCV开源视觉库,提出基于快速步进算法的数字纹理修复,基于Sauvola算法改进后的局部二值化算法实现纹饰提取与增强,在Unity3D平台下根据二维图像建立三维模型,最后建立基于VR的交互展示子系统。结果表明,使用快速步进算法可有效修复陶器表面的损伤问题,改进后的局部二值化算法相较于其他算法具有良好的效果,数字化VR展示子系统可有效还原三维陶器模型。

Under the pottery making process and long-term preservation,various damage problems will occur.In response to the above problems,a set of digital texture restoration,ornamentation enhancement and three-dimensional interactive display system of pottery images were designed.In order to obtain the image of the pottery and comb the damage problem,based on the OpenCV open source visual library,the digital texture restoration based on the fast marching algorithm is proposed.The improved localized binarization algorithm based on the Sauvola algorithm is used to extract and enhance the texture.Based on the 2 Dimage in the Unity 3 Dplatform.Establish a 3 Dmodel and finally build a VR-based interactive presentation subsystem.The results show that the fast travel algorithm can effectively repair the damage problem of the ceramic surface.The improved local binarization algorithm has better effect than other algorithms.The digital VR display subsystem can effectively restore the 3 Dpottery model.
