摘　　要：针对在三维成像的虚拟重建过程中,以真实性为目标函数忽略了视觉传达需求下差异度重要性的问题,本文以视觉传达为约束条件,设计三维图像虚拟重建方法。通过将视觉传达中的差异度作为约束条件,采用视觉传达差异度的属性设计碰撞匹配重构算法,利用差异度阈值引起的区域碰撞,对三维图像进行重建。研究证明:所设计方法虚拟重建后的三维图像清晰度、边缘细节较为好,呈现的视觉传达效果较好。能够有效避免由于像素丢失造成的像素提取过程内存在不稳定状态或者呈现的不明显因素。In a virtual reconstruction,three-dimensional(3D)imaging takes authenticity as the objective function,ignoring the importance of difference under the demand of visual communication.In this paper,a 3D image virtual reconstruction was designed using visual communication as the constraint.The collision matching reconstruction algorithm was designed using the difference in visual communication.Furthermore,the 3D image was reconstructed using the regional collision caused by the threshold difference using the difference degree in visual communication as the constraint.It is proved that the 3D image reconstructed under visual communication constraints has good quality and edge details,and the visual communication effect is good.It can effectively avoid the unstable state or inconspicuous factors caused by pixel loss in the pixel extraction process.
