摘要
针对传统虚拟现实图像生成速率较低问题,提出一种基于真实感的虚拟现实图像生成技术。依据给定的阈值对比灰度方差最小值,进行初始匹配、松弛匹配,建立特征点对应关系,通过最小中值法对匹配误差进行消除,利用递归操作构建网格纹理虚拟现实图像层次模型以及纹理快速合成算法对模型中的图像颜色进行匹配与合成,并对纹理进行映射处理,从而生成具备真实感的虚拟现实图像,将该技术与传统虚拟现实图像生成技术进行对比实验,实验结果表明该技术的图像生成速率最高,更适用于虚拟现实图像的生成。
In view of the problem that the traditional virtual reality image generation rate is low,this paper proposes a virtual reality image generation technology based on reality.According to the given threshold,the minimum value of gray variance is compared,and the initial matching and relaxation matching are carried out.The corresponding relationship of feature points is established,and the matching error is eliminated by the minimum median method.Then the grid texture virtual reality image hierarchical model is constructed by recursive operation,and the fast texture synthesis algorithm is used to match and synthesize the image color in the model,and the texture is mapped.The experimental results show that this technology has the highest image generation rate and is more suitable for the generation of virtual reality images.
