我们提出了一个获取和恢复扭曲文档图像的框架。我们恢复的目的是创建一个平面文件的平面表示，这个平面文件经历了任意和未知的刚性变形。为了完成这种恢复，我们的框架获取并平坦弯曲文档的3D形状，以确定可以纠正由文档形状引起的图像失真的非线性图像变换。我们的框架是为图书馆和博物馆的数字化工作而设计的，在这些工作中，非常古老和严重损坏的手稿被成像。
We present a framework for acquiring and restoring images of warped documents. The purpose of our restoration is to create a planar representation of a once planar document that has undergone an arbitrary and unknown rigid deformation. To accomplish this restoration, our framework acquires and flattens the 3D shape of a warped document to determine a nonlinear image transform that can correct for image distortion caused by the document's shape. Our framework is designed for use in library and museum digitization efforts where very old and badly damaged manuscripts are imaged.
