基于三维边缘重构的文档图像自动矫正方法
Automatic Document Image Rectification through 3D Boundary Reconstruction
【摘要】 针对照相机对装订书籍拍照时由于书面弯曲产生文档图像变形的问题,利用从图像中提取的文档边缘作为特征信息,通过参数控制自动实现文档图像的矫正。与以往研究成果相比,本方法无须人工标记及特殊设备,具有一定的优越性。实验结果能够有效地对变形文档图像进行矫正。
【Abstract】 When taking bound document with cameras,image distortion occurs because of the warped document surface.An approach was proposed to rectify the bound document image automatically by abstracting document boundaries in the image as the feature information and through parameter controls.Compared with other people’s earlier research,the approach is advanced because it does not need manual marking or special equipment.The experiment results can rectify the distorted document image efficiently.
