摘要
三维虚拟视点合成能够让设计师在计算机上创建出非遗文创产品包装设计的立体效果,提供更真实、更全面的视觉体验,为此提出基于双边滤波算法的非遗文创产品包装设计三维虚拟视点合成。首先,采用基于相对高度深度的深度图提取方法,从非遗文创产品包装设计图像中获取其深度信息;针对深度图像提取过程中产生的缺陷如噪声、孔洞等,引入改进的自适应联合双边滤波方法,实施图像修复,从而获取更加完整、清晰的非遗文创产品包装设计深度图像;最后,引入基于深度图像的渲染(DIBR)技术,推出缺失深度的修复值,并通过DIBR的针孔相机模型和三维图像转换方程,将修复后的深度图像转换为三维虚拟视点图像,并实现其三维虚拟视点合成。实验结果表明,所提方法应用后,能够精确地修复填补非遗文创产品包装RGB图像空缺,整体完整度较高;完整且精确地展现出非遗文创产品包装设计的三维虚拟视点效果,色彩饱满,瑕疵较少;PSNR值和SSIM值均得到提高。三维虚拟视点合成方法能够有效修复缺陷图像,提升了三维虚拟点合成后的质量,满足实际非遗文创产品包装设计需求。
3D virtual viewpoint synthesis enables designers to create three-dimensional effects for packaging design of non heritage cultural and creative products on computers,providing a more realistic and comprehensive visual experience.Therefore,a 3D virtual viewpoint synthesis for packaging design of non heritage cultural and creative products based on bilateral filtering algorithm is proposed.Firstly,a depth map extraction method based on relative height depth is adopted to obtain depth information from packaging design images of non heritage cultural and creative products;Aiming at the defects such as noise and holes generated during the process of depth image extraction,an improved adaptive joint bilateral filtering method is introduced to implement image restoration,thereby to obtain more complete and clear depth images of packaging design for non heritage cultural and creative products;Finally,depth image-based rendering(DIBR) technology is introduced to derive the repair value for missing depth,and through DIBR pinhole camera model and 3D image conversion equation,the repaired depth image is converted into a 3D virtual viewpoint image,and its 3D virtual viewpoint synthesis is achieved.The experimental results show that the proposed method can accurately repair and fill the RGB image gaps in the packaging of non heritage cultural and creative products,with a high overall integrity;Fully and accurately display the three-dimensional virtual viewpoint effect of packaging design for non heritage cultural and creative products,with full colors and fewer defects;Both PSNR and SSIM values have been improved.The 3D virtual viewpoint synthesis method can effectively repair defective images,improve the quality of 3D virtual point synthesis,and meet the packaging design requirements of actual non heritage cultural and creative products.
