Opencv flatten curved sheet
Webfirst implemented to project a curved surface to a rectangle area. Then pose normalization is performed on word level to restore the local distortions. The key problem of geometric correction of a document image is to recover its 3D shape. A direct way to this is to use the range data obtained from a 3D scanner [9], [1], [2]. WebFigure 1. Left: Frontal view RGB. RIght: BEV from IPM Homography based IPM. In computer vision, homography is a transformation matrix H when applied on a projective plane maps it to another plane (or image).
