A theoretical justification of warping generation for dewarping using CNN

•A mathematical model for warping generation is proposed.•The model uses geometric parameters like the camera angle, camera position, distance from the object to camera and curvature the surface to generate warping.•Synthetic images are generated using the model.•Value of the geometric parameters is estimated using CNN from a 2D warped image.•Performances of both the synthetic image generation and dewarping model are analysed.
