论文摘要
在将三维对象的表面投射到二维表面的过程中，由于透视扭曲，该物体表面上的图像将根据表面曲率的水平具有不同程度的失真程度。本文提出了一种不精确的方法，可以使这种类型的变形在规则弯曲的身体的表面上。该方法的主要思想是大致估计网格表面细分，该细分可用于通过对象的二维图像的轮廓曲线来描述三维对象的表面。然后，将每个网格块带有不同尺寸和形状成反比的矩形，形状和大小完全相同。最后，每个相同的矩形依次进行拼接和重组以获得大致平坦的矩形。本文将介绍并展示使用此方法解决弯曲页面扁平问题的特定过程和结果，然后证明此方法的可行性和局限性。
In the process of projecting the surface of a three-dimensional object onto a two-dimensional surface, due to the perspective distortion, the image on the surface of the object will have different degrees of distortion according to the level of the surface curvature. This paper presents an imprecise method for flattening this type of distortion on the surface of a regularly curved body. The main idea of this method is to roughly estimate the gridded surface subdivision that can be used to describe the surface of the three-dimensional object through the contour curve of the two-dimensional image of the object. Then, take each grid block with different sizes and shapes inversely transformed into a rectangle with exactly the same shape and size. Finally, each of the same rectangles is splicing and recombining in turn to obtain a roughly flat rectangle. This paper will introduce and show the specific process and results of using this method to solve the problem of bending page flattening, then demonstrate the feasibility and limitations of this method.
