面向虚拟场景生成的Morphing扩充方法

针对基于特征线段的Morphing方法在虚拟场景生成中的缺陷,研究提出了一种扩充方法,称为Morphing 。该方法通过增加图像间的映射关系,使其满足透视性质;增加了由点到特征线中点的距离控制参数,增强对特征线作用大小调节;同时,引入了位置特征线的概念来控制场景中对象可见性的变化,使得特征线的作用更合理,变换更真实。Morphing 克服了以前方法中存在的透视、可见性、特征线岐义、效率低等问题,提高了绘制效率,结果图像更逼真。

The Extended Morphing Method Facing Virtual Scene Rending

This thesis proposes an extended Morphing method to overcome the limitation of Morphing method based on diagnostic line. We called this method "Morphing ". This method adds the mapping relationship between images to satisfying perspective. And it adds the distance from pixel to the midpoint of diagnostic line as a parameter to adjust the effect of diagnostic line. At the same time, we introduce the concept of "position diagnostic line" to control the visibility of objects in the scene, that make the effect of diagnostic line more realistic. The Morphing overcome some problems in traditional morphing method based on diagnostic line, and accelerate the rending processing. The result scene image is more realistic.
